Abstract

Micronutrients like zinc and iron play an important role in growth and development of mungbean. The scarcity of these micronutrients also has an impact on seed quality of mungbean. A field experiment on optimization of nutrient management practices through soil and foliar application in mungbean was conducted during summer season 2021. The treatments included control, 0.5% ZnSO4 at flower initiation (FI), 0.5% ZnSO4 at FI & pod initiation (PI), 0.5% FeSO4 at FI, 0.5% FeSO4 at FI & PI, 0.5 % ZnSO4 & 0.5% FeSO4 at FI, 25 kg ha-1 ZnSO4 soil application, 50 kg ha-1 FeSO4 soil application. Plant height (29.85 cm), number of branches per plant (8) and number of nodules per plant (16) were improved significantly by foliar spraying of 0.5% ZnSO4 and 0.5% FeSO4 at FI. Significantly maximum no. of pods per plant, seeds per pod, seed yield (521 kg ha-1) and stover yield (1307 kg ha-1), net returns (Rs. 8020/ha) and benefit cost ratio (1.28) were recorded under 0.5% ZnSO4 and 0.5% FeSO4 spray at Flower initiation stage.
