Response of Integrated Nutrient Management on Wheat (Triticum aestivum L.) and its Residual Effect on Succeeding Crop

A field experiment was conducted at College Agronomy Farm, BA College of Agriculture, Anand Agricultural University, Anand, Gujarat during rabi season during of 2005 and 2006 on loamy sand soil. The experiment was conducted to study the effect of integrated nutrient management on wheat ( Triticum aestivum L. ) and its residual effect on green gram under middle Gujarat Agro-climatic Conditions. There were twenty-four treatment combinations comprising combination of three organic manure treatments (Control, Vermicompost@5 t/ha and FYM @ 10 t/ha) with four phosphorus/bio-fertilizer treatments (60 kg P 2 O 5 /ha, 20 kg P 2 O 5 /ha + PSB, 40 kg P 2 O 5 /ha + PSB and PSB alone) and two sulphur levels (0 kg S/ha and 40 kg S/ha) were tested in the split plot design with four replications. Application of organic manures, i.e., FYM@10 t/ha and vermicompost 5 t/ha with 60 kg P 2 O 5 /ha or 40 kg P 2 O 5 /ha + PSB and 40 kg S/ha produced maximum wheat grain and straw yield. Significantly higher green gram grain and straw yield was recorded in organic manure treatment with application of 60 kg P 2 O 5 /ha or 40 kg P 2 O 5 /ha + PSB and 40 kg S/ha in succeeding crop. Treatment FYM@10 t/ha with 60 kg P 2 O 5 and 40 kg S/ha recorded higher grain and straw yield under residual nutrient. In wheat-green gram cropping sequence treatment FYM@10 t/ha with 60 kg P 2 O 5 and 40 kg S/ha recorded higher net realization.
