Abstract:

One experiment was conducted in the district of Bla during the rainy seasons 2015 and 2016. The object was to test in farmer field’s technique package susceptible to improve crop yields and income in the context of climate change. The relay cropping of maize-cowpea, the intercropping of millet-cowpea and sorghum-cowpea with and without technique package were assessed in a dispersed blocks experimental design where each farmer was representing one replication. The technique package was involving: confection of diguettes perpendicular to the direction of the slope, use of improved and soaked seed, mineral fertilizer micro dosing and seeding mechanization, plant density, sowing at right date. The practice of technique package has significantly improved crop yields (53% for maize and 75% for cowpea in relay cropping; 73% and 60% for millet and cowpea in intercropping; 49% and 39% for sorghum and cowpea in intercropping). It has allowed improvement in the water use efficiency (62% in the relay cropping, 70% in the intercropping millet-cowpea and 47% in the intercropping sorghum-cowpea). Net benefits of 125 000, 112 000 and 121 000 FCFA/ha were from the relay cropping, intercropping millet and sorghum-cowpea. The anticipation of the practice of recommended agricultural techniques has improved the resilience of the cropping systems. Yield of the cropping systems and farmer’s income have been improved in the context of climate change.
