Sesame (Sesamum indicum L.) is an important cash crops that generates substantial income for producers in eastern region of Burkina Faso. Although sesame production has increased during this decade, but the yields remained low. The present study aims to improve sesame productivity, through determination of its cropping system in three agro-climatic zones of Burkina Faso. A survey was carried out on a sample of 300 producers in six communes (Bogandé, Mani, Diabo, Tibga, Pama and Kompienga) in eastern zones of Burkina Faso. A semi-structured questionnaire was used to collect information quantitative and qualitative information. Results of the Ascending Hierarchical Classification showed three types of cropping system in the study area. A semi-intensive system (SCS1) with highest yields (358.17 ± 131.7 kg/ha) in the Sahelian and South Sudanian zone, and two extensive systems (SCS2 and SCS3) in the North Sudanian zone and South Sudanese zone. All of these different cropping systems are characterized by the cropping practices especially, the types of seeds used, the sowing method, the weeding method, soil fertility management, the level of education of farmer and sesame yield recorded. The study allowed to establish the typology of sesame-based cropping system in the study area, an important tool for the development of the sesame sector and technology adaptation for improving productivity.

This research aims to characterize and establish a typology of garden farmers according to their knowledge and use of biopesticides. The study was conducted in Louda, a village in the commune of Boussouma in the North Central region of Burkina Faso. A semi-structured socio-economic survey was conducted among 20 garden farmers, equally divided between men and women. The results of the survey showed that 70% of the garden farmers cited caterpillar as the major pest and leaf curl as the major disease. Twenty-five (25) % and 15% of the garden farmers use biopesticides as a phytosanitary treatment against caterpillar and leaf curl respectively. Unregistered industrial synthetic chemical pesticides for other crops are often used by garden farmers. Ignorance or not of the existence of biopesticides and their use against crop pests are the main criteria that establish the typology of garden farmers in Louda. Age, sex, instruction, mode of access to land, family size, number of salaried agricultural workers and average annual income of the garden farmers are the socio-economic parameters that discriminate this typology. This typology is therefore associated with the socio-economic characteristics of garden farmers.

Bambara groundnut is a food seed legume with enormous agronomic and nutritional potential. However, it remains a neglected crop. In order to improve its productivity in relation to soil and climatic conditions, the present study was conducted in Tenkodogo from July to October 2021. Soil characterization was carried out according to FAO guidelines directives before the setting up of experimental device. Experimental design consisted of the trial following a completely randomized block design with four replications. The effects of applying of 0 (BP0), 30 (BP30), 60 (BP60), 90 (BP90) and 120 (BP120) kg ha-1 of Burkina phosphate (BP) on two varieties KVS246 and KVS 235 of Bambara groundnut were compared. Crop management consisted of a flat plowing, direct application of BP, sowing distances of 0.40 m x 0.20 m and ridging on the 49th day after sowing. Results showed that the soil of experimental site are an iron and manganese sesquioxide’s soils class, specifically to shallow leached ferruginous tropical soil and should corresponding an endo petroplinthic lixisol. This acidic soil is characterized by a sandy surface texture and clay at depth, well drained, with low mineral content. In reference to the research results, the soil and climatic conditions of experimental site are potentially suitable for Bambara groundnut cropping. Treatments not significantly improved Bambara groundnut yields by verities. On this soil, the variety KVS 246 would better interact with applying of 60 and 90 kg ha-1 of BP and the variety KVS 235 with 120 kg ha-1 of BP to improve Bambara groundnut yield parameters compared to the control. Further research is needed over several years to better understand the effects of rock phosphate on Bambara groundnut crop and residual soil fertility.

Knowledge of the characteristics of upland rice cultivation systems is a lever for the development of rice cultivation in Burkina Faso. This study aims to highlight the typology of upland rice cultivation systems in three localities: East, Hauts Bassins and Central Plateau regions of Burkina Faso. A survey was carried out among a sample of 293 producers in the localities concerned. The Multiple Correspondent Analysis identified three upland cultivation systems: the low-intensive Upland rice cultivation system with rotation (SCRPS1); the Intensive Upland Rice Cultivation System (SCRPS2) and the low-Intensive Upland Rice Cultivation System without rotation (SCRPS3). Elements that make it possible to distinguish the systems are: age, sex, level of education of the farmer, upland rice area, equipment, crop rotation, type, quantity and the number of fertilizers used in upland rice system. The practices of cropping systems differ from one locality to another. In short, the SCRPS1 type is the most practiced by producers and the SCRPS2 type with a high yield (2759.04 kg / ha) presents itself as an interesting prospect to promote for rice production generating income for an improvement of income women farmers.
