Abstract:
A field experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture & Technology Kumarganj, Faizabad (U.P.) during kharif season of 2013 to access the effect of various nutrients on rainfed rice and to work out the best combination of foliar spray of nutrients on the performance of rice. The experiment was conducted in RBD with 3 replications with 12 nutrient management modules viz., T₁-100% RDF as basal, T₂-100% RDF as basal + 3 water spray, T₃-75% RDF + 2.5 Tonnes FYM, T₄-50% RDF + 5 Tonnes FYM, T₅-50% RDF + 3 foliar spray of 20 kg Urea ha^-1, T₆-50% RDF + 3 foliar spray of 20 kg Urea ha^-1+ 10 kg ZnSO₄ ha^-1, T₇-100% RDF + 30 kg ZnSO₄ ha^-1 as soil application, T₈-100% RDF + 2 foliar spray of 5 kg FeSO₄ ha^-1, T₉-100% RDF + 2 foliar spray of 10 kg Borax ha^-1, T₁₀-100% RDF + 2 foliar spray of 10 kg Sulphur ha^-1, T₁₁-100% RDF + 2 foliar spray of 20 Urea ha^-1+ 10 kg ZnSO₄ ha^-1 and T₁₂-100% RDF + 2 foliar spray of 10 kg ZnSO₄ ha^-1+ 5 kg FeSO₄ ha^-1+ 10 kg Borax ha^-1+10 kg Sulphur ha^-1. Treatment T₁₂ (100% RDF + 2 foliar spray of 10 kg ZnSO₄ ha^-1+5 kg FeSO₄ ha^-1+10 kg Borax ha^-1+10 kg Sulphur ha^-1) found significantly superior over all the rest treatments in all the aspects of growth parameters during the investigation. Treatment T₁₂ (100% RDF + 2 foliar spray of 10 kg ZnSO₄ ha^-1+5 kg FeSO₄ ha^-1+10 kg Borax ha^-1+10 kg Sulphur ha^-1) increases all the growth parameters viz., plant height, number of shoots, dry matter accumulation and leaf area index. Treatment T₁₂ found significantly superior and produced taller plants (76.72 cm), maximum number of shoots (432.0), dry matter accumulation (158.0) and leaf area index (4.32) as compared to the other treatments. Protein content also found maximum in Treatment T₁₂ (8.875%) which was significantly superior over rest of the treatments.
