Effect of Micronutrient Application on Growth, Yield and Quality of Green Gram Growing Iron and Zinc Deficient Soils of Renapur Tahsil, Latur

Abstract

The present investigation entitled “Effect of micronutrient application in green gram growing iron and zinc deficient soils of Renapur Tahsil, Latur” during Kharif season of the year, 2022-2023 at A Field experiment was conducted at farmers field At. Post-Dawangaon Tq-Renapur Dist- 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. Among the various treatments the application of RDF + 25 kg ha-1 FeSO4 + 25 kg ha-1 ZnSO4 (T7) significantly increased the growth parameters viz., highest plant height (52.19 cm at 60 DAS), number of branches(10.64 at 60 DAS), leaf area (540.67 cm2 plant-1at 60 DAS), dry matter content (9.54 g plant-1 at 60 DAS), total chlorophyll content (9.93 mg g-1 at 45 DAS) and number of nodules per plant (19.70), Yield parameters viz., higher number of pods plant-1(15.43), number of grains pod-1(11.88), seed yield kg ha-1 (1575.46) and straw yield kg ha-1 (1864.68) at harvest and the improvement in quality parameters i.e. test weight (35.23 g), protein content (22.37 %) and protein yield kg ha-1 (347.27) at harvest and was found at par with treatments 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).
