Abstract:

In the plain of SENO located in the Sahelian Est zone of Mali, farmers grow mainly pearl millet intercropped with cowpea on Sandy-loam soils. In order to improve yields of these crops, farmer apex organization, the association of professional farmer organizations of Mopti has conducted demonstrations on the package of technologies in pioneer farmers’ fields. One study was undertaken in this area to assess the impact of this technology package on crop yields             and farmer income. The investigations concerned 25% of 200 producers in the area where 7 farmers were from the control village, 18 and 15 from the first and the second scaling out villages, 10 from the village test.  Crop yields and net benefit have proportionally varied according to the increase of technical package contents. The fertilizer option in Bérély was one dominated treatment. The marginal rate of return was 106% and 87% in the scaling out village of Anakana and the village test of Téna respectively. Referring to the minimum marginal rate of return of 50%, all the tested packages are economically attractive. However huge efforts should be put in extension activities and agricultural input supply in order to reduce the costs that varied recorded in the test villages.
