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.

Impact of Zinc and Thiourea Application on Growth and Yield of Summer Green Gram (Vigna radiata L.)

“…Application of Zn encouraged greater root growth and sink size development (number of pods plant -1 ), which ultimately led to increased seed yield [9]. Ram and Katiyar also concluded that application of 10 kg Zn/ha significantly increased number of nodules and pods per plant, seeds per pod, test weight over preceding levels [10]. Seed soaking with thiourea@ 500 ppm TU2 Foliar spray of thiourea @ 500 ppm at 30 DAS TU3 Foliar spray of thiourea @ 500 ppm at 45 DAS TU4 Foliar spray of thiourea @ 500 ppm at 30 and 45 DAS With the application of 4.5 kg Zn ha -1 together with the recommended dose of NPK (20-40-00 kg ha -1 ) significantly increased seed yield (873 kg ha -1 ) and stover yield (1378 kg ha ) (Table 2).…”
