Nutrient management is one of the most significant strategies that have an impact on mungbean (Vigna radiata L.) growth and development. Therefore, the field trial was carried out at RRTTSS, Kirei, Sundargarh during summer season 2021. Experiment consists of eight treatment including T1- control (RDF: 20-40-20 kg/ha and FYM 5 tha-1), T2 - T1+ 0.5% ZnSO4 FI, T3 - T1+ 0.5% ZnSO4 FI & PI, T4 - T1+ 0.5% FeSO4 FI, T5 - T1+ 0.5% FeSO4 FI & PI, T6 - T1+ 0.5% ZnSO4 and 0.5% FeSO4 FI, T7 - T1+ 25 kgha-1 ZnSO4 soil application, T8 - T1+ 50 kg ha-1 FeSO4 soil application and replicated thrice with RBD. The results of the experiment revealed that yield attributes viz. pods per plant (15.63), seeds per pod (10.50), Seed yield (521 kg ha-1) and stover yield (1307 kg ha-1), total uptake of N (36.47 kg ha-1), P (4.60 kg ha-1), K (27.95 kg ha-1), Zn (47.99 g ha-1) and Fe (156.98 g ha-1) were recorded significantly highest under the treatment of 0.5% ZnSO4 and 0.5% FeSO4 foliar spray at flower initiation stage along with RDF and FYM. The highest N, P and K uptake was found with application of 0.5% ZnSO4 and 0.5% FeSO4 at flower initiation stage (20.09 kg ha-1), (2.17 kg ha-1) and (3.37 kg ha-1) in seed & stover (16.38 kg ha-1), (2.43 kg ha-1) and (24.58 kg ha-1), respectively.

The culinary value of mungbean (Vigna radiata L.) makes it one of the most valuable pulses.  The enhanced and inorganic farming method of India has been able to attract special attention from scientists and growers. The crucial aspect in pulse productivity is the use of the proper micronutrients in the appropriate proportions. Therefore, the field experiment was carried out at RRTTSS, Kirei, Sundargarh during summer season 2021. Experiment consists of eight treatments replicated thrice with RBD. The results revealed that seed yield (521 kg ha-1), stover yield (1307 kg ha-1), gross returns (Rs. 36470/ha), net returns (Rs. 8020/ha) and benefit cost ratio  (1.28) and nutrient content N (3.86% & 1.25% in seed and stover), P (0.45% & 0.19% in seed & stover), K (0.65% & 1.88% in seed and stover) were recorded significantly highest  under the treatment of 0.5% ZnSO4 and 0.5% FeSO4 foliar spray at flower initiation stage along with RDF and FYM. Highest Zn content (51.01 ppm) in seed and (17.43 ppm) in stover  was obtained in T3- T1+ 0.5% ZnSO4 FI & PI stage. The maximum iron content in seed (117.50 ppm) as well as in stover (84.97 ppm) was observed in T5 - T1+ 0.5% FeSO4 at FI & PI   stage.

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.
