Evaluation of the Agronomic Traits and Grain Yield of Mung bean (Vigna radiata L.) by Different Levels of Phosphorus Fertilizer with Row Spacings at Abine Germama Kebele in Adamitulu Jido kombolcha Wereda

Mung bean is among the most important pulses crop cultivated from low to midland agro-ecological zones of world including Ethiopia. The study was conducted at Abine Germama Kebele in 2020/21 cropping season ( rainy ) on Adamitulu Jido Kombolcha Wereda. We used mung variety so called Arkebe for this experiment. trial also determine optimum row spacing and phosphorus fertilizer rate better grain yield assess economic value using Phosphorus production. soil medium total nitrogen (0.143%), had available (2.42 mg kg -1 soil), moderate organic matter (2.252) contents cation exchange capacity (6.15 cmol soil). highest number seeds per plant (12.37) counted interaction effects 40kg/ha 15cm spacing. above ground biomass (8064.48 ha (2493.83 obtained 60kg/ha 10cm intra (0.25) harvest index calculated effect 60kg P 2 O 5 with 40cm x maximum net benefit (86772.51 ETB − 1 . marginal return unit production cost recorded when planted application (MRR = 942%). we advised farmers 60 best production, but since level treatments so, needs add levels beyond future study.
