چکیده
Summary Increasing yields in farmer fields is a priority to address increasing food demands. The study was conducted within four wheat-growing areas Ethiopia: Debre Birhan, Hosaina, Sinana and Maychew. objectives were identify (1) best-bet soil fertility management options based on agronomic performance economic evaluation (2) key yield-reducing factors an survey among 55 participating farmers. Two types of on-farm experiments conducted: researcher-managed trials that tested combinations nutrients, including micronutrients, organic resources or both over two cropping seasons farmer-managed comparing ‘ improved practice ’ against ‘farmer’s practice’ . Fertilizer treatment affected wheat productivity Birhan ( p < 0.01), site limited sulphur. Here, full NPK increased the control 0.05), whereas combination manure better than application as only source added nutrients 0.05). Applying half recommended with micronutrients achieved similar fertilizer treatment. In had no significant effect productivity, although zinc resulted additional 26–57% yield relative other treatments. Maychew, 0.05) observed. lower rates nitrogen phosphorous A plant densities also We conclude nutrient use important specific cases, investments optimize have huge potential increase productivity.
