Effect of micronutrient application on growth and yield in green gram (Vigna radiata L.)

Abstract

The present investigation entitled “Micronutrient Management in Green Gram (Vigna radiata L.)” during Kharif season of the year, 2023-2024 at a field experiment was conducted at experimental field College of Agriculture Latur. The experiment was layout in RBD with three replications and a recommended variety of green gram BM 2003-2 as a test crop along with ten treatments.The results in a nutshell indicated that the growth and yield were significantly influenced by the application of iron and zinc with RDF of green gram. The growth parameters viz., plant height, number of branches, leaf area, dry matter content and number of nodules significantly increased with application of RDF + 25 kg ha-1 FeSO4 + 25 kg ha-1 ZnSO4 + 10 Kg Borax and was found at par with treatment T8 RDF + 25 kg ha-1 FeSO4 + 25 kg ha-1 ZnSO4, T4 RDF + S.A. Grade-I micro-nutrient @ 25 kg ha-1 + F.A. Grade-II micro-nutrient @ 0.5% at 25 and 40 DAS and treatment T2 RDF + S.A. Grade- I micro-nutrient @ 25 kg ha-1.A significantly higher number of seed yield ha-1 and straw yield ha-1 with application of RDF + 25 kg ha-1 FeSO4 + 25 kg ha-1 ZnSO4 + 10 Kg Borax (T9) and was found at par with treatments T8 RDF + 25 kg ha-1 FeSO4 + 25 kg ha-1 ZnSO4, T4 (RDF + S.A. Grade-I micro-nutrient @ 25 kg ha-1 + F.A. Grade- II micro-nutrient @ 0.5% at 25 and 40 DAS) and treatment T2 (RDF + S.A. Grade- I micro-nutrient @ 25 kg ha-1).
