Agro-ecosystem degradation is a real socio-environmental problem in the Sahel. Face to the declining of yields from cultivated soils, populations are adopting various adaptation strategies. This study was conducted to assess the impact of three agricultural technologies on the evolution of soil fertility in the Sahel area of Burkina Faso. Soil was sampled from the agro-systems and submitted to physico-chemical and biological analyzes in laboratory. We evaluated soil infiltration capacity , inventoried herbaceous vegetation.Also grasses biomass was measured, and millet straw and grains were weighted in the field. Results from this study showed that plowing + bund + organic manure (LDF) treatment was the best management option in the Sahel. It reduces soil infiltration time by 1.65%, increase soil fine elements (clay and silt), chemical elements (N, P and K), exchangeable bases and cation exchange capacity. In addition, soil respiration under LDF treatment is significantly higher (P = 0.001) than other treatments. Simple plowing, is not recommended in the Sahel. It must necessarily be accompanied by measures to improve the nutrient content of soils, especially with manure. These results could guide agricultural actors (farmers, agricultural extension agents, NGOs) for sustainable farming in the Sahel areas.

Land degradation is a threat to biodiversity and has negative impacts on agricultural communities by aggravating food insecurity. The objective of this study was to examine the responses of native woody species and soil variables to different levels of glacis degradation in the Sahelian zone of Burkina Faso. Field investigations were performed according to the degradation gradient outlined in the Braun-Blanquet method. Soil samples were collected and analyzed in the laboratory. The results indicate that the diversity and diametric structure of woody species are functions of the glacis degradation stage. A total of eight (08) woody species were recorded on the glacis (7 species in non-degraded glacis, 7 species in moderately-degraded glacis and only 1 species in degraded glacis). Acacia raddiana is the only local woody species present in all three glacis degradation stages. It is recommended to rehabilitate degraded glacis in the Sahel in response to desertification. The high levels of sand, nitrogen (N) and carbon (C) characterize the non-degraded and moderately-degraded glacis, whereas the high levels of silt, clay, bulk density, pH-H20 and pH-Kcl indicate degraded glacis. This study can inform the future rehabilitation and management of Sahelian glacis.

Beans play a significant role in human diet especially in developing nations like Nigeria, the largest producer and consumer of beans in the world. To ensure food safety, heavy metal levels need to be monitored on regular basis to control human exposure through dietary intake. This study aimed at assessing the levels of heavy metals in some species of beans available in Ife market, Osun State, Nigeria. Samples of each species of beans were bought and analyzed for heavy metals using X-ray Fluorescence spectroscopy. Results showed that the concentration of heavy metals such as Cu was present at a level ranging from 0.131–0.205 ppm, and Zn was present at level ranging from 0.073–0.182 ppm. Cd was present at concentration < 0.039 ppm. Cu, Zn and Cd levels in natural beans sample were observably below maximum permissible limit set by WHO in Table 2. Therefore, it can be concluded that majority of these beans species were not contaminated with the studied heavy metals, hence pose no immediate health risk to human.

Aims: Evaluate four potato genotypes in terms of sprouting and coloring depending on the storage time at 8 °C and their potential for use by the potato processing industry.
Study Design: The experiment was carried out in a completely randomized design, in a split-plot scheme with five replications, each replication consisting of two tubers.
Place and Duration of Study: Tubers were obtained from the production area of Perdizes, Minas Gerais, Brazil (Latitude 19º 21’ 10’’ N and Longitude 47º 17’ 34’’ E and 1000 m).
Methodology: The genotypes Alibaba, Arsenal, Antartica and Babylon were stored at 8° C for up to 180 days, with the analysis of sprouting, visual coloration before and after frying, parameters L*, b* and c*.
Results: All potato genotypes were light colored before frying, category 1 (USDA). Babylon obtained the best parameters of b * and c *. Antartica and Babylon potato genotype showed low sprouting.
Conclusion: The Arsenal and Antartica potato genotype have potential for use by the processing industry due to the color of the sticks before and after frying and low sprouting.
The Alibaba potato genotype was darkly colored after frying.
Babylon was the potato genotype with the best color of the sticks after frying and less germination.

A pot experiment was conducted at the experimental net house of the Department of Soil Science, Sylhet Agricultural University, Sylhet, Bangladesh to observe the effect of fertilizers on yield and nutrient uptake of local aromatic rice varieties during the Aman season of 2015. The experiment was laid out in a Randomized Complete Block Design with three replications. Five local aromatic rice varieties (Kalizira: V1, Muktasail: V2, Nagrasail: V3, Maloti: V4 and Chinigura: V5) and four packages of fertilizers (F1:  Recommended package i.e. 45-10-20-10-0.5 kg ha-1 of N-P-K-S-Zn, F2: 2/3rd of recommended package, F3: 1/3rd of recommended package, and F4: Control) were used. Urea, TSP, MoP, gypsum and ZnSO4 were used as N, P, K, S and Zn source, respectively. According to the treatment, all fertilizers were applied as basal during final pot preparation while urea was applied in two equal splits (one half as basal and another half at 40 DAT). Nutrient content and uptake of the aromatic rice varieties were significantly affected by the application of different fertilizer packages (with few exceptions). Mostly Kalizira (1.10-0.44-2.31-0.67-13.75 g pot-1 of N-P-K-S-Zn) and/or Nagrasail (1.15-0.46-2.70-0.62-11.74 g pot-1 of N-P-K-S-Zn) varieties showed the highest nutrient uptake in grain and straw with recommended package of fertilizers. While in maximum cases Chinigura (0.41-0.16-0.76-0.197-3.17 g pot-1 of N-P-K-S-Zn) was observed to have the lowest with control treatment. In case of post harvest soil nutrient analyses, Kalizira and/or Chinigura variety associated with recommended package of fertilizers showed the highest nutrient status.
