| Popis: | Three sets of field experiments were conducted both on farmer fields and on experiment stations on Kobo areas of eastern Amhara region during 2013 and 2014 cropping seasons to evaluate and introduce dry land crop production technologies that would reduce crop failure and increase productivity of crops. Integrated technologies that were evaluated include: micro-dose fertilizer, moisture conservation, seed priming, intercropping, and row planting. The experimental design was randomized complete block (RCB) with three replications consisted of 14 treatments. The results revealed that the highest grain yield (5032 and 4328 kg/ha) of sorghum was recorded with application of recommended fertilizer rate + primed seed + tied ridge and micro-dose fertilizer + primed seed + tied ridge + intercropping with haricot bean, respectively. For pearl millet, the highest grain yield (3355 and 3145 kg/ha) was recorded with application of micro-dose fertilizer + dry seed + tied ridge and recommended fertilizer rate + dry seed + tied ridge, respectively. For maize, the highest grain yield (4414 and 4392 kg/ha) was recorded with application of micro-dose fertilizer + primed seed + tied ridge + intercropping mung bean and recommended fertilizer rate + dry seed + tied ridge. From the results of on-station and on-farm trials at Kobo, recommended fertilizer rate + primed seed + tied-ridge for sorghum testing crop, recommended fertilizer rate + dry seed + tied-ridge for pearl millet and micro-dose fertilizer + primed seed + tied ridge + intercropping with mung bean for maize was recommended for kobo and similar areas. |
