Response of Mung Bean Yield to Boron and Different NPK Formulas

A factorial field experiment was conducted in the autumn season of 2018 to study the effect of different NPK formulas (control, di-ammonium phosphate NPK 18-46-0, neutral fertilizer 20-20- 20, and high potash 18-46-30) and boron levels (0, 20, 40 mg L-1 ) on mung bean yield in a randomized complete block design (RCBD) with three replications. Local variety seeds were planted on 15/8/2018 on both sides of ridges 80 cm at 15 cm between hills. The results showed that adding all NPK formulas improved yield and its components by giving high plant pods number, seeds number pod-1 , and yield of seeds compared to the control, and adding high potash formula was superior (26.77, 6.99 and 1300.2 kg ha-1 ). Boron levels caused a significant increase in pods per plant, seeds number per pod, and yield of seed compared to the control treatment, and the level 40 mg l-1 gave 24.9 pods, 6.99 seeds, and 1207 kg ha-1 . The interaction between NPK fertilizer and boron caused a significant effect and high potash fertilizer with 40 mg l-1 boron gave the highest seed yield (1207 kg ha-1 .)
