Abstract

Water saving in agriculture intends to raise water use efficiency resulting in higher economic yield on irrigated farm land with minimum usage of water. An experiment was conducted to investigate the effect of deficit furrow irrigation and mulching on yield and water productivity of Phaseolus Vulgaris, in Anchar Woreda, Eastern Ethiopia. The experiment was conducted using a randomized complete block design (RCBD) with three replications considering three irrigation level (100%ETc, 85%ETc and 70% ETc) and three mulching technique (no mulch, straw and plastic mulch). The results showed that maximum Phaseolus vulgaris yield (5.38 ton ha-1) was achieved under full irrigation combined with plastic mulch, which significantly exceeded all other treatments. The application of plastic mulch under full irrigation increase yield by 28.70% compared to non-mulched conditions. However, the highest water use efficiency (0.64 kg m-3) was observed under deficit irrigation at 70% ETc combined with plastic mulch. Therefore, for water scarce regions such as Anchar district the adoption of deficit furrow irrigation at 85% ETc combined with plastic mulching is recommended. In areas with sufficient water resources, full irrigation under plastic mulch is preferable.
