Effect of micro nutrient application in soybean grown on zinc, iron and boron deficient soil of Renapur tahsil, Latur

The field experiment was carried out on “Effect of Micro Nutrient Application in Soybean Grown on Zinc, Iron and Boron Deficient Soil of Renapur Tahsil, Latur” during Kharif season of year, 2023-24 at farmer’s field having zinc, iron and boron deficient soils of shri. Prabhakar Ramrao Nagargoje R/O. Dawangaon Tal. Renapur Dist. Latur. The experiment was laidout in RBD with three replications and recommended variety of soybean KDS-753 as a test crop along with ten treatments. The results indicated that the growth and yield were significantly influenced by application of micronutrient sources in soybean. The growth parameters viz., plant height, number of branches, number of nodules, leaf area and dry matter yield were significantly increased with application of RDF + S.A. Grade-I @ 25 kgha-1 + F.A. Grade-II @ 0.5% at 30 and 45 DAS (T4) but found at par with treatment T2 (RDF + S.A. Grade-I micro-nutrient @ 25 kgha-1) and T9 (RDF + S. A. FeSO4 @25 kg ha-1+ ZnSO4 @25 kg ha-1+ Borax @10 kg ha-1). Significantly higher seed yield and straw yield were recorded with application of RDF + S.A. Grade-I @ 25 kgha-1 + F.A. Grade-II @ 0.5% at 30 and 45 DAS (T4) and it was at par with treatment T2 (RDF + S.A. Grade-I micro-nutrient @ 25 kgha-1), T9 (RDF + S. A. FeSO4 @25 kg ha-1+ ZnSO4 @25 kg ha-1+ Borax @10 kg ha-1) and T8 (RDF + S.A. FeSO4 @ 25 kgha-1 + S.A. ZnSO4 @ 25 kgha-1).
