Flood recession farming is as an important supplement to rainfed agriculture in West Africa. Every year, large areas are flooded along riverbanks and temporary lakes. When water recedes from the flooded areas, farmers plant crops. This study describes the flood recession farming in the Yelimane district of Kayes region in Mali and assesses different ways to intensify the system. The use of external inputs in this system is minimal. Field experiments were undertaken over two years to test crop establishment methods, soil tillage, increasing plant density, use of organic and mineral fertilizer, and improved varieties. These technologies increased sorghum yield as compared to the control in the following descending order: Seed priming + fertilizer (77.1%), NPK + organic fertilizer (74%), seedling transplantation + micro fertilization (61.3%), improved varieties (49%), mounding (34%), and urea application (24.9%). The technology seed priming in combination with mineral fertilizers was promising because of the high yield and the low labor demand. Nitrogen fertilizer is needed in flood recession agriculture as the soils and the deposited sediments are low in nitrogen. Farmers’ choice of technology will depend on the yield level, net return per hectare, labor use, and access to inputs.
This paper examines the subject of linking local knowledge with scientific research on soil fertility, in both theoretical and applied terms. The end goal of this effort is to collaborately develop improved soil management techniques via epistemological integration of local and scientific knowledge. A brief examination of some of the historical problems and failings of introduced agricultural technologies is presented. In an effort to explicate the shared and divergent perspectives, local knowledge systems and institutional scientific research are compared according to classificatory systems and fertility management regimes. The scientific bases for soil classification and soil fertility management are based on a review of the literature. The final part of this paper examines how cultivators in the Commune of Madiama in Mali have received and perceived scientific research.
A study was conducted to evaluate the viability of existing and alternative technologies adaptable to the study landscape and similar areas in Madiama Commune, Mali, using cropping systems simulation modelling, Crop Syst. Results showed that overall yield efficiency compared to the attainable optimum production for 2- and 3-year rotation was 52 and 47%, respectively. In addition, long-term simulation has allowed for the determination of yield probabilities and risks linked to production and the choice of the best technology among the compared systems. PR 2t, which is small ruminant manure at 2 tonnes every year, was the dominant and most risk-efficient practice among the four organic fertilizer application technologies. The long-term 30-year average yield outputs from the three fertilizer microdosing management practices showed no significant yield difference.
IMPACT OF BREWERY REFUSE AND Leucaena leucocephala AS FOOD SUPPLEMENT ON CANE RAT GROWTH UNDER BREEDING CONDITIONS The impact of brewery's on cane-rat growth refuse and Leucena leucocephala added to food supplement was tested on sixteen cane-rat were used for the experiment. Ten animals were submitted to a standard food ration. Six of the animals were organized in three groups of two animals per group. A food ration made of a brewery refuse was used for the first group. The second group received a food ration consisting of leaves of Leucaena leucocephala. The third group received no food. All animals were fed with grass twice daily and each animal received a daily ration of 83 g of food supplement. Biochimical analysis of ingredients Fantodji A. et al.
