Performance of mungbean under deficit irrigation application in the semi-arid highlands of Ethiopia

摘要: Abstract Knowing the performance of short season crops under deficit irrigation has a paramount importance for arid and semi-arid regions with limited access to on-farm water harvesting or other infrastructure. In this research, mungbean, newly introduced crop into cropping systems in Ethiopia, stage-wise uniform was tested at Sekota Dryland Agricultural Research Center, Northern Ethiopia. Eight treatments – four applications were evaluated during 2010/2011 dry season. Plant phenological variables, grain yield use efficiency used evaluation. The results showed that stress shortened dates 50% flowering maturity, but proportionate reduction yield. obtained varied between 1366 kg/ha 331 mm optimal seasonal 492 kg/ha when one-fourth ETc (102 mm) uniformly applied though out growing flowering/reproductive stage noted as most sensitive growth 24.9% compared control treatment. all stages, is linearly associated (R2 = 0.93) amount applied, over range tested. IWUE values ranged from 0.248 0.304 kg/m3. It can therefore be concluded provided midseason avoided depending on volume available, different arrangements using pond possible.
