Abstract:
A field experiment was conducted during Zaid 2021 Crop Research Farm, Department of Agronomy, SHUATS, Allahabad, (U.P.). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 6.7), low in organic carbon (0.35%), available N (230 kg ha^-1), medium available P (20 kg ha^-1) and available K (189 kg ha^-1). The treatment consisted of 0.5% foliar spray of FeSO₄ and ZnSO₄ at 35 and 55 days after sowing with soil application of FeSO₄ and ZnSO₄ @ 20 kg/ha and 25 kg/ha respectively. There were 10 treatments each replicated thrice. The experiment was laid out in Randomized Block Design. The result showed that growth parameters viz., plant height (181.71 cm), dry weight (77.32 g), number of leaves/plant (18.13), Leaf area index (4.40), CGR (15.33 g m^-2 day^-1) and RGR (0.0155 g/g/day) and yield attributes viz., number of grains/head (1980.40), test weight (12.02 g), grain yield (3.22 t/ha), stover yield (6.58 t/ha) and harvest Index (32.83%) were recorded maximum in treatment T₇ (75% RDN + 25% nitrogen through vermi compost + 0.5% Foliar spray of FeSO₄ at 35 and 55 Days after sowing). These parameters were significantly influenced by application of foliar spray of FeSO₄ along with vermi compost. However, net return of ₹ 74,023.32 and B.C. ratio 2.25 was recorded higher with application of 75% RDN + 25% nitrogen through vermi compost + 0.5% Foliar spray of FeSO₄ at 35 and 55 Days after sowing.
