| dc.description.abstract | Mungbean (Vigna radiata (L) Wilczek), is a recently introduced grain legume crop with multiple uses for food, fix nitrogen from the atmosphere, source of animal feed and income for small holder farmers in Ethiopia particularly in Ankober District. Despite its high potential uses and export demand, current national productivity is 1.2 ton ha -1 which is much lower than its’ attainable yield 1.5-2.0 ton ha -1 due to poor crop management such as poor site selection, imbalance fertilization, improper planting density, diseases and insect pests. Field experiment was conducted to in Ankober district North East Ethiopia in 2020 cropping season to evaluate the effects of blended NPSB biofertilizer rates, and intra row spacing on yield and yield components of mungbean. The Treatment consisted of factorial combinations of three blended NPSB rates (75, 100, and 125 kg NPSB ha -1 ), two biofertilizer rates (0 and 500 gm ha ), and three intra row spacing of planting (5, 10, and 15 cm) laid out in randomized complete block design with three replications. Data on plant height, number of total and effective branches, number of pods per plant, number of seed per pod, above-ground biomass and grain yield of mungbean were collected and subjected to ANOVA and LSD at 0.001, 0.01% and 0.05% SAS version 9.4. The results indicated that the two-way interaction effect of blended NPSB with biofertilizer rates; blended NPSB with intra row spacing; and biofertilizer rates with intra row spacing had significantly affected grain yield. Accordingly, the highest above-ground dry biomass yield (3871.70 kg ha -1 ) and grain yield (1639.82 kg ha -1 ) was recorded by the interaction blended 100 kg NPSB ha -1 with 10 cm intra row spacing. Similarly, the partial budget analysis revealed that the highest net benefit 38,525.38 ETB ha -1 with acceptable MRR 2587.36 % was obtained from 100 kg blended NPSB + 10 cm intra row spacing. Therefore, it can be concluded that producing mungbean at the rate of 100 kg NPSB ha -1 + 10 cm intra row spacing was found to be a promising treatment combination for better production and productivity and higher net benefit in the study area for mungbean. However, repeating similar experiments over season and across locations is important to give reliable recommendations. | en_US |
