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).
