Effect of Pseudomonas Fluorescens in the Germination and Growth of Prosopis Laevigata under Greenhouse Conditions

Abstract Mesquite (Prosopis laevigata) is a tree of arid and semi-arid areas of northern and central Mexico. This species allows erosion control, atmospheric nitrogen fixation, and improves soil quality. Pseudomonas fluorescens is a rhizobacterium that favors plant growth-promoting rhizobacteria (PGPR). Also, promotes seed germination and development of Mesquite plants under adverse environmental conditions.

The aim is to evaluate the role of bacterial strains A7 and Sv of P. fluorescens, using two types of soil (vertisol and phaeozem), and adding vermicompost (0, 25, 50, 75 and 100 tons/ha) in the germination and growth stages of mesquite (Prosopis laevigata).We tested the characteristics developed by the plants over 180 days. A randomized experimental design with four repetitions was used to test the seed germination rate and 16 more variables in the greenhouse, such as morphology, dry biomass accumulated, and morphological indices through the randomized factorial experimental design with three factors, 2x3x5x3.

Regarding the control treatment, the use of the bacterial strain A7 of P. fluorescens inhibited the germination of mesquite seeds, while the strain Sv favored seedlings development. We observed opposite effects; inhibition and growth in the germination stage, and development of the seedlings observed at 180 days when using the A7 and Sv strains of P. fluorescens.

Keywords Arid and semi-arid areas, Bacterial strain, Biofertilizer, Mesquite, Plant growth-promoting Rhizobacteria (PGPR), Pseudomonas fluorescens, Vermicompost.

Effect of Industrialization and Urbanization on Agriculture

Abstract Industrialization and urbanization becomes a bane for the agriculture now days. With increase in industrialization and urbanization, the growth of agriculture sector decline continuously. Large area of land is covered under industry and infrastructure, which results in shortage of agriculture productive lands. The waste products of industry and urban areas are flowed in water bodies such as river, lakes and ponds which pollute them and make them unsuitable for any kind of use. The harmful effluents released from industry contaminate the air with harmful gases and suspended material. These gases and suspended particles affect the growth and development of plants and animals. The suspended particles are inhale during breathing and cause blockage in veins and arteries of animals and humans. To feed the ever increasing population of our country, the farmer put high pressure on shrinking land to get higher output. For this, farmer use modern technology and chemicals which reduce the productivity and fertility of soil. The polluted water of lakes and ponds become poisonous for the water living entities and results in death of plants and animal species. The waste effluents of urban areas and industry have high concentration of heavy metals which are very poisonous for animals and plants which survive under water and on land. The growth of plants and microbes in soil is reduced due to increase in concentration of heavy metal in soil. The effects of industries and urbanization need to be decreased to get a healthy environment for plants and animals. Special management practice needs to be developed to suppress this increasing problem to survive on earth.

Keywords— industrialization, urbanization, suspended particles, productivity, fertility, heavy metals, etc.

Extraction and Formulation of Perfume from Lemongrass

Abstract Perfume extraction is the extraction of aromatic compounds from raw materials, using methods such as distillation, solvent extraction etc. The extracts are essential oils, absolutes, butters, depending on the amount of waxes in the extracted product. Here, in this work solvent extraction, Enfleurage method, hydrodistillation and steam distillation methods were used to extract essential oil from lemongrass leaves. Distillation based recovery processes such as steam and vacuum distillation are preferred for the extraction of essential oils from plant materials. Other methods include solvent extraction, expression or enfleurage. In the present work, four methods are used for oil extraction namely solvent extraction, hydrodistillation and enfleurage. By using solvent extraction, 2.07% yield of essential oil was obtained. In enfleurage method, we obtained 1.957% oil yield. 0.946% yield of oil was obtained by hydro distillation process. The steam distillation process gave 0.70% yield of oil. From the analysis solvent extraction gave the highest yield because of the less exposure air and heat and this confirm the literature value. The extracted essential oil was formulated into perfume using a fixative and carrier solvent.

Keywords— Perfumes, Lemongrass, Enfleurage method, hydrodistillation.

One Case of Internal Fixation Treatment for Tibia and Fibula Fracture of Dogs

Abstract Tibia and fibula fracture is a common fracture of hind limb in dogs. It is caused by external force on the hind limb. After fracture happens, external fixation is often used for treatment, and the effect is ideal. However, if the fracture site is close to the joint, we suggest to use internal fixation as far as possible, so as not to cause sequelae of joint stiffness. The author diagnosed the fracture of tibia and fibula in the left hind limb of the poodle through combining the incidence, clinical manifestations and DR examination, and then used the internal fixation plate for internal fixation. Under postoperative care, the dog recovered well.

Keywords— fracture, tibia and fibula, internal fixation, internal fixation plate.

Rubber Tree Cultivation and Improvement: Rootstock-Scion Compatibility between Hevea Species and Cultivated Planting Materials

Abstract Rootstocks have a clear effect on rubber tree growth and development during the seedling and immature stages. However, the exploration of Hevea species as rootstocks is relatively uncommon in the general practices in the cultivation and improvement programmes in Malaysia. Hevea species were tested in this research including Hevea brasiliensis, Hevea benthamiana, Hevea camargoana, Hevea guianensis, Hevea nitida, Hevea pauciflora, Hevea rigidifolia and Hevea spruceana. This research examined the successful bud-grafted percentage between scion and rootstock of different Hevea species and cultivated planting materials. The results demonstrated that rootstock-scion of H. benthamiana-PB 260 achieved the highest successful bud-grafted percentage at 94.5%, followed by H. nitida-RRIM 2001 (93.8%), H. nitida-PB 350 (92.3%) and H. pauciflora-PB 260 (90.8%). The lowest successful bud-grafted percentage came from H. benthamiana-RRIM 2025 at 51.1 %. Therefore, the exploration of Hevea species as potential rootstocks based on the successful bud-grafted percentage between rootstock-scion and their compatibility could be applied as a speed indicator for rubber nurseries to produce high quality planting materials.

Keywords bud-grafted, Hevea species, rootstock-scion.

Criteria for the Selection of Vegetable Growth-Promoting Bacteria to be applied on Roselle Crop (Hibiscus Sabdariffa L.) and Bioremediation

AbstractIn order to define which are the most important criteria for the selection of plant Growth-Promoting bacterial strains of the Hibiscus sabdariffa L. crop (Roselle), bacterial strains isolated from the roots of Roselle plants of two varieties (Creole and Spider) were used, collected in the community of Río de los Peces, municipality of Candelaria Loxicha, Oaxaca and seeds of the same varieties. To characterize the varieties, the following were determined: total germination percentage (TGP), germination speed (GS), the root length (RL), the stem length (SL), the dry root biomass (DRB), the dry stem biomass (DSB) and the chlorophyll content (CC). Three types of LED lamps were used to illuminate the seedlings. The seeds inoculated with cells of six selected bacterial strains were grown in a greenhouse to determine: the stem length (SL) at 3, 45 and 65 days after sowing (das). The treatments were distributed under a completely random design and comparison of means (Tukey, p = 0.05). The TGP, DSB and DRB parameters were not useful in the selection process of the strains that promoted plant growth to a greater degree. The GS and SL to be considered safe criteria or not, what is important is the relationship of what happens at the time of germination and development of the seedlings in the laboratory and greenhouse. The SL of the plants in the greenhouse showed differences between strains, but not regarding the control and also only observed in the first days of development (3 das). The CC did not prove to be a good selection criterion either. The lamp composed of 15% white light, 27% blue light and 58% red light was the one that most promoted root growth.

Keywords—Plant Growth-Promoting bacteria strains, Hibiscus sabdariffa L, Bacterial strains selection criteria, LED lamps.

Inoculation of (Prosopis Laevigata) by Arbuscular Mycorrhizal Fungi in Different Doses of Organic Matter in Two Types of Soil

AbstractThe mesquite tree (Prosopis laevigata), besides its conventional uses, has a high potential to recover agricultural areas with salinity problems. It improves the physical and chemical properties of the soil, and in the rehabilitation of degraded arid and semi-arid zones, or those tending to desertification.The aim of this research was to test the effect of organic fertilization and inoculation with Glomus sp. on mesquite trees. We did the experiment under greenhouse conditions. The effect of applying Glomus sp. and organic matter in different doses during the growth of shoots and roots was evaluated in 13 agronomic variables in mesquite seedlings grown in Lithosols and Xerosols soils. We used a complete randomized block design with three replications. After 180 days, we analyzed the data using Statistical Analysis Software (SAS) version 9.2. We observed a positive and significant effect on the growth of the agronomic variables studied under greenhouse conditions, and inoculation with Glomus sp. The organic matter factor presented significant differences (p ≤ 0.05). We determined that the ideal dose was 55 g per experimental unit. According to the soil used, positive effects (p ≤ 0.05) were observed for 50% of the agronomic variables in the Xerosols soil with relation to the Lithosols soil. We concluded that the inoculation of Prosopis laevigata with Glomus sp., and adding organic matter favors the growth of both the shots and the roots of the plant.

Cattle Ticks and Risk Factors Related to Tick Infestation of Livestock in Periurban Farms in Southern Cote D'ivoire

Abstract Tick-borne diseases are a global public health problem, particularly in sub-Saharan Africa, where most of the disease is caused by malaria and many other diseases of viral, parasitic or bacterial origin. This study aimed to identify the bovine tick’s species in cattle farms and to determine possible risk factors related to tick infestation in Abidjan district and Azaguié commune. Thus, in July 2019, thirteen (13) herds distributed in these localities were visited for tick sampling and to conduct epidemiological investigations. At each visit, ticks were harvested from 15 cattle per herd. All the farms visited were infested with ticks. 96.92% of sampled animals had ticks. A total of 1796 ticks were collected of which 89.42% (1606) were adults, 10.41% (187) were pupae and 0.17% (3) was larvae. Two species of ticks have been identified, Amblyomma variegatum with 25% of the population and Rhipicephalus (Boophilus) microplus with 75%. 96% of the cattle were infested by ticks of the species R. (B.) microplus and 56% of the cattle were infested by ticks of the species A. variegatum. The co-infestation of cattle by the two identified species was 53%. The distribution of the sexes showed that in the species A. variegatum, males were more numerous (13.44% for males and 8.76% for females). However in the species R. (B.) microplus, females were more numerous (5.08% for males and 62.3% for females).The analysis of risk factors associated with tick infestation in cattle has shown that factors such as Undefined parks, Type of pasture, Training in the use of acaricides and Presence of wild animals contribute to major ectoparasite infestations in cattle. Tick samples collected from peri-urban farms in the district of Abidjan and the locality of Azaguié as part of this study, indicate that the relatively recent introduction of the species Rhipicephalus (Boophilus) microplus presents a threat to animal and human health.

Keywords— Ticks, Rhipicephalus (Boophilus) microplus, Risk factors, Côte d’Ivoire.

Rubber Tree Cultivation and Improvement: Biological Aspects and the Risk of Inbreeding Depression

Abstract Rubber trees (Hevea spp.) are among the essential plants cultivated and have contributed to Malaysia’s economy growth for many decades. Latex harvested from rubber trees is an irreplaceable raw material and accounts for a wide range of uses in tires, tubes, footwear, rubber gloves, and other rubber-based products. There were many attempts to produce ideal rubber tree for increasing latex yield production through the improvement programmes since 1950s. However, the risk of inbreeding depression and the planting materials produced from the chosen parents that are closely related in the improvement programmes is fairly high. Inbreeding depression caused discouraging effects such as uneven bark surface, leaf disease infection, easily damaged by wind blows and eventually reducing the production of latex yield overall. This review highlights the important of biological aspects for latex production in rubber tree and seeing minimizing the risk of inbreeding depression with the necessity of broader genetic base in the rubber tree cultivation and improvement programmes.

Malting Sludges as Soil Amendment

Abstract Residual sludge that results from the treatment of malt house effluents produced during the malting of barley in malt house (Argentina) was evaluated to determine its fertilising potential and capability for improving soil as a way to reuse or recycle this material. The Cabildo soil (Southwest of Buenos Aires Province), of the typic Argiustoll subgroup had a sandy clay-loam texture and was tested in this field experiments. This soil plots (4 m2) were amended with equivalent malting sludges doses of 5, 15, and 25 Mg/ha. When biosolids, like malting sludges, are incorporated as an amendment, many micronutrients are provided. Chemical properties of the soil, particularly the pH, EC (Electrical Conductivity) and Cation Exchange Capacity (CEC), were improved. Dactylis glomerata L. were utilised as growing crop (forage) in this field test, productivity ( Dry matter) and quality (protein %) gave results following 0,205 kg/m2 and 11.94 % at control in comparison with 0,4 kg/m2 and 15.15 % of amended soil. Calcium concentration in grasses was significantly different for control (4651 mg/kg-1) in comparison with high sludge dose (8907 mg/kg-1), the same trend was found with micronutrients like Copper and Molybdenum. This result from field test indicate that this residual sludge constitutes a suitable amendment for agricultural soils, increasing quality and productivity of Dactylis glomerata L and improving several soil properties.

Evaluation of the Development of Roselle (Hibiscus Sabdariffa L.) in Two Soil Types with Interaction of Bacterial Cells and Vermicompost

Abstract— In this study, we tested the growth of two varieties of Roselle (Hibiscus sabdariffa) cultivated in two types of soils and the effects of the inoculation of seeds with cells of bacterial strains and vermicompost. (H. sabdariffa) are a member of the Malvaceae family and an important plant because its calyxes are used to produce beverages, prepare food, in the textile industry, cosmetology, perfumery, medicine, etc.

This research was carried out at the Postgraduate College, Montecillo Campus, Mexico. The experimental design was completely randomized blocks with a factorial arrangement (4x3x2): four levels of organic matter factor, three levels of bacterial strains factor, and two levels of soil factor with three repetitions. The variables tested were: germination percentage (GP), plant height (PH), stem diameter (SD), the number of leaves (NL), foliar area (FA cm2), radical volume (RV cm3), dry aerial part biomass weight (DAPBW), dry root biomass weight (DRBW), dry calyx biomass weight (DCBW) and chlorophyll content (CC). The effects of soil and bacterial strains showed significant differences (p ≤ 0.05) on the agronomic characteristics of (H. sabdariffa) plants. The organic matter factor only presented significant differences (p ≤ 0.05) in the germination percentage and growth variables of the vegetative phase.

To increase crop production, the use of wastewater and microorganisms is proposed. Vermicompost exploded the percentage of germination, height, the number of leaves and stem diameter during the first weeks of growth, presenting important results in Creole variety (farmers’ local variety). By inoculating seeds with cells of bacterial strains, A9m and A7 helped significantly to stimulate plant growth, finding a better response in A9m strain. The effects of soil factor showed significant differences (p ≤ 0.05) in soil irrigated with residual water over agronomic characteristics satisfying the nutritional requirements of the crop.

Inoculation of (Prosopis Laevigata) by Arbuscular Mycorrhizal Fungi in Different Doses of Organic Matter in Two Types of Soil

AbstractThe mesquite tree (Prosopis laevigata), besides its conventional uses, has a high potential to recover agricultural areas with salinity problems. It improves the physical and chemical properties of the soil, and in the rehabilitation of degraded arid and semi-arid zones, or those tending to desertification.The aim of this research was to test the effect of organic fertilization and inoculation with Glomus sp. on mesquite trees. We did the experiment under greenhouse conditions. The effect of applying Glomus sp. and organic matter in different doses during the growth of shoots and roots was evaluated in 13 agronomic variables in mesquite seedlings grown in Lithosols and Xerosols soils. We used a complete randomized block design with three replications. After 180 days, we analyzed the data using Statistical Analysis Software (SAS) version 9.2. We observed a positive and significant effect on the growth of the agronomic variables studied under greenhouse conditions, and inoculation with Glomus sp. The organic matter factor presented significant differences (p ≤ 0.05). We determined that the ideal dose was 55 g per experimental unit. According to the soil used, positive effects (p ≤ 0.05) were observed for 50% of the agronomic variables in the Xerosols soil with relation to the Lithosols soil. We concluded that the inoculation of Prosopis laevigata with Glomus sp., and adding organic matter favors the growth of both the shots and the roots of the plant.

Keywords— Earthworms, Glomus sp., Lithosols soil, mesquite tree, vermicompost, Xerosols soil.

Cattle Ticks and Risk Factors Related to Tick Infestation of Livestock in Periurban Farms in Southern Cote D'ivoire

Abstract Tick-borne diseases are a global public health problem, particularly in sub-Saharan Africa, where most of the disease is caused by malaria and many other diseases of viral, parasitic or bacterial origin. This study aimed to identify the bovine tick’s species in cattle farms and to determine possible risk factors related to tick infestation in Abidjan district and Azaguié commune. Thus, in July 2019, thirteen (13) herds distributed in these localities were visited for tick sampling and to conduct epidemiological investigations. At each visit, ticks were harvested from 15 cattle per herd. All the farms visited were infested with ticks. 96.92% of sampled animals had ticks. A total of 1796 ticks were collected of which 89.42% (1606) were adults, 10.41% (187) were pupae and 0.17% (3) was larvae. Two species of ticks have been identified, Amblyomma variegatum with 25% of the population and Rhipicephalus (Boophilus) microplus with 75%. 96% of the cattle were infested by ticks of the species R. (B.) microplus and 56% of the cattle were infested by ticks of the species A. variegatum. The co-infestation of cattle by the two identified species was 53%. The distribution of the sexes showed that in the species A. variegatum, males were more numerous (13.44% for males and 8.76% for females). However in the species R. (B.) microplus, females were more numerous (5.08% for males and 62.3% for females).The analysis of risk factors associated with tick infestation in cattle has shown that factors such as Undefined parks, Type of pasture, Training in the use of acaricides and Presence of wild animals contribute to major ectoparasite infestations in cattle. Tick samples collected from peri-urban farms in the district of Abidjan and the locality of Azaguié as part of this study, indicate that the relatively recent introduction of the species Rhipicephalus (Boophilus) microplus presents a threat to animal and human health.

Keywords— Ticks, Rhipicephalus (Boophilus) microplus, Risk factors, Côte d’Ivoire.

Rubber Tree Cultivation and Improvement: Biological Aspects and the Risk of Inbreeding Depression

Abstract Rubber trees (Hevea spp.) are among the essential plants cultivated and have contributed to Malaysia’s economy growth for many decades. Latex harvested from rubber trees is an irreplaceable raw material and accounts for a wide range of uses in tires, tubes, footwear, rubber gloves, and other rubber-based products. There were many attempts to produce ideal rubber tree for increasing latex yield production through the improvement programmes since 1950s. However, the risk of inbreeding depression and the planting materials produced from the chosen parents that are closely related in the improvement programmes is fairly high. Inbreeding depression caused discouraging effects such as uneven bark surface, leaf disease infection, easily damaged by wind blows and eventually reducing the production of latex yield overall. This review highlights the important of biological aspects for latex production in rubber tree and seeing minimizing the risk of inbreeding depression with the necessity of broader genetic base in the rubber tree cultivation and improvement programmes.

Malting Sludges as Soil Amendment

Abstract Residual sludge that results from the treatment of malt house effluents produced during the malting of barley in malt house (Argentina) was evaluated to determine its fertilising potential and capability for improving soil as a way to reuse or recycle this material. The Cabildo soil (Southwest of Buenos Aires Province), of the typic Argiustoll subgroup had a sandy clay-loam texture and was tested in this field experiments. This soil plots (4 m2) were amended with equivalent malting sludges doses of 5, 15, and 25 Mg/ha. When biosolids, like malting sludges, are incorporated as an amendment, many micronutrients are provided. Chemical properties of the soil, particularly the pH, EC (Electrical Conductivity) and Cation Exchange Capacity (CEC), were improved. Dactylis glomerata L. were utilised as growing crop (forage) in this field test, productivity ( Dry matter) and quality (protein %) gave results following 0,205 kg/m2 and 11.94 % at control in comparison with 0,4 kg/m2 and 15.15 % of amended soil. Calcium concentration in grasses was significantly different for control (4651 mg/kg-1) in comparison with high sludge dose (8907 mg/kg-1), the same trend was found with micronutrients like Copper and Molybdenum. This result from field test indicate that this residual sludge constitutes a suitable amendment for agricultural soils, increasing quality and productivity of Dactylis glomerata L and improving several soil properties.

Evaluation of the Development of Roselle (Hibiscus Sabdariffa L.) in Two Soil Types with Interaction of Bacterial Cells and Vermicompost

Abstract— In this study, we tested the growth of two varieties of Roselle (Hibiscus sabdariffa) cultivated in two types of soils and the effects of the inoculation of seeds with cells of bacterial strains and vermicompost. (H. sabdariffa) are a member of the Malvaceae family and an important plant because its calyxes are used to produce beverages, prepare food, in the textile industry, cosmetology, perfumery, medicine, etc.

This research was carried out at the Postgraduate College, Montecillo Campus, Mexico. The experimental design was completely randomized blocks with a factorial arrangement (4x3x2): four levels of organic matter factor, three levels of bacterial strains factor, and two levels of soil factor with three repetitions. The variables tested were: germination percentage (GP), plant height (PH), stem diameter (SD), the number of leaves (NL), foliar area (FA cm2), radical volume (RV cm3), dry aerial part biomass weight (DAPBW), dry root biomass weight (DRBW), dry calyx biomass weight (DCBW) and chlorophyll content (CC). The effects of soil and bacterial strains showed significant differences (p ≤ 0.05) on the agronomic characteristics of (H. sabdariffa) plants. The organic matter factor only presented significant differences (p ≤ 0.05) in the germination percentage and growth variables of the vegetative phase.

To increase crop production, the use of wastewater and microorganisms is proposed. Vermicompost exploded the percentage of germination, height, the number of leaves and stem diameter during the first weeks of growth, presenting important results in Creole variety (farmers’ local variety). By inoculating seeds with cells of bacterial strains, A9m and A7 helped significantly to stimulate plant growth, finding a better response in A9m strain. The effects of soil factor showed significant differences (p ≤ 0.05) in soil irrigated with residual water over agronomic characteristics satisfying the nutritional requirements of the crop.

Short Communication: Interactive Association of fungus and root-knot nematodes on Sarnalli crop (Ipomea Reptans)

Plants develop close association with many soil microorganisms especially with fungi and nematodes under field conditions that are either beneficial or harmful to plants. (Goswami et al., 2000) The fungus nematode interactions are numerous, varied and provide open field for significant research. (Goswami and Mittal, 2002) Fungus is an essential component of the interacting system of fungus—nematode complex disease and plays an important role in the disease etiology. Since the publication of Atkinson’s report (1892) that Fusarium wilt of cotton was more severe in the presence of root-knot nematode (Meloidogyne spp.) than in its absence, a large volume of data has been accumulated to date which firmly establishes the involvement of plant-parasitic nematodes in interactions with fungal plant pathogens on various crop plants. (Mittal and Goswami, 2002) In the present paper an attempt has been made to study the fungi associated with root-knot nematodes from trans-Yamuna river belt of Delhi infecting Sarnalli crop (Ipomea reptans).

Assessment of the Profitability Window of Broiler Chickens Farming in Bobo-Dioulasso, Burkina Faso

Abstract The purpose of this study, was to determine the optimal size for broiler farming and the optimal hen’s raising time to achieve technically and economically profitable farming .The study was conducted in the suburban area of Bobo-Dioulasso where three groups of six broiler farms were identified: the 1st group was made of farms that had 200 to 400 heads, the 2nd group had between 400 to 600 heads, and the 3rd group had more than 1000 heads.. In each group, three farms had completed the hen raising within 35 days and the other three within 42 days. We found that among the chicken coops, 17% respected the building orientation standards and most had low roofs (< 2.5 m) with a short extended eave (< 1 m) and a low dwarf wall (< 20 cm). Almost all of the producers (94.4%) used concomitantly a feed formula and a vaccination schedule. In terms of conduct, crawl space, lighting, preheating and heating were effective on all farms. In fact, 72.2% used coal-fired heaters, 16.7% radiant heater and 11.1% heating bulbs. Upon installation of the chicks (day 1), 76.5% of producers were administering veterinary products. In terms of good density of feeding and watering material, 61% were met at start-up, 43% at growth and 29% at finish. For those who observed the recommended density standards, 88.89% were encountered at start-up, 44% at growth and 5.2% at finish. The highest mortalities and average live weights (AVL) were found on large farms and 42 days raising while the highest Feed conversion ratios (FCR) were recorded in farms with 35 days of driving. The highest chicken production costs were seen in smaller flocks (1831±233) and the larger the flock size at finish, the better the profit (822 ± 151). In conclusion, the category of flock size that allowed the highest benefit for farmers in the suburban area of Bobo-Dioulasso is the group had more than 1000 heads and therefore should be recommended for extension purpose.

Characterization of the Sweet Potato Production System in the Kou Valley in the Western Zone of Burkina Faso

Abstract— In the search for diversification of sources of income, producers have adopted the cultivation of sweet potato in their rotation, especially in irrigated plains. Despite the growing interest of producers for this crop, few results exist on the production systems as practiced by producers with a view to the sustainability of the activity.

The present study aims to characterize the sweet potato production system on the developed perimeter of the Kou valley. To this end, surveys were carried out in the farming community on 30 farms. The results showed that sweet potato is cultivated in rotation with rice in the plain. One hundred percent (100%) of the producers surveyed practice rotation on their agricultural plot. Fertilization is a common practice, growers use NPK and Urea. Labor remains a concern for the crop for more than 80% of producers. Strengthening the technical capacities of producers would be beneficial through appropriate training.

Keywords— Sweet potato, sustainability, system, production, Kou valley, Burkina Faso.
