The soil is clayey in texture (Vertisol) with pH 7.95, bulk density 1.27 dS/m, available nitrogen, phosphorus and potassium of 224, 20.8 and 342 kg per ha, respectively. The experiment included two factors. The main factor had two levels of manure treatments (M1-no manure and M2-FYM at 5 t/ha) and the sub-factor had five levels of fertilizers (F1-no fertilizer, F2-recommended NPK @ 40:40:12 kg per ha, F3-SSNM based on STCR equation, F4- F3 + micronutrients @ Zn @25 kg/ha+S@10 kg/ha and F5 - F3+if soil is deficient add 25 % more than F2 and if soil is medium apply 25% less than recommended). The experiment was laid out in split-plot design with three replications at fixed site during both the years.
