Abstract

A present investigation was conducted for two rabi seasons during 2005-06 and 2006-07 in field of College Agronomy Farm, B.A. College of Agriculture, Anand Agricultural University, Anand, Gujarat, to study the effect of integrated nutrient management on wheat (Triticum aestivum L.) on loamy sand soil. There were twenty-four treatment combinations comprising combination of three organic manure treatments (M0: Control, M1: Vermicompost @ 5 t/ha and M2: FYM @ 10 t/ha) with four phosphorus/bio-fertilizer treatments (P1: 60 kg P2O5/ha, P2: 20 kg P2O5/ha + PSB, P3: 40 kg P2O5/ha + PSB and P4: PSB alone) and two sulphur levels (S0 : 0 kg S/ha and S1: 40 kg S/ha) were tested in the split plot design with four replications. The results revealed that application of FYM@ 10 t/ha recorded significantly higher seed yield over control treatment, but it was at par with vermicompost 5 t/ha treatment. Application of FYM @ 10 t/ha treatment recorded 22.72 and 20.86% grain yield over control and vermicompost 5 t/ha treatments. Application of phosphorus @ 60 kg P2O5/ha recorded higher yield and which was statically at par with 40 kg P2O5/ha + PSB treatment. Higher dose 40 kg S/ha produced maximum yield. Protein content, P content in straw and S content in grain and straw was higher in FYM @ 10 t/ha treatment, while N and P content in grain was higher in organic manure treatments. Recommended dose of phosphorus fertilizer recorded higher protein content, N content in grain and S content in straw. Application of 40 kg S ha-1 recorded higher protein content, N content in grain and S content in grain as well as straw.
