Effect of Soil and Foliar Application of Zinc and Iron on Yield, Nutrient Content and Quality of Summer Mungbean

Abstract

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.
