Abstract
A field experiment was conducted during wet and dry seasons of 2010-11 and 2011-12 at Instructional farm, Orissa University of Agriculture and Technology, Bhubaneswar on sandy loam soil with medium availability of organic carbon (0.54%), available N (295 kg ha-1), P (15 kg ha-1), K (162 kg ha-1) and low availability of S (8 ppm), Zn (0.33 ppm) and B (0.43ppm).The experiment was laid out in randomized block design with eleven treatments and three replications. During kharif season, rice variety ‘Lalat’ was raised with different integrated nutrient management practices involving RFD (N-P2O5-K2O @ 80-40-40- kg/ha), FYM, S, Zn and B. During rabi season ‘Lalat’ was grown in these treatment plots with acommon dose of N-P2O5-K2O @ 80-40-40 kg ha-1 only to study the residual effect of FYM, S, Zn and B on growth, yield, nutrient uptake and economics of rice, as well as the effect on rice-rice cropping system. Application of recommended fertilizer dose (N-P2O5-K2O @ 80-40-40 kg ha-1)+ZnSO4 @ 25 kg ha-1+B @ 1 kg ha-1 recorded the highest values of yield attributes viz. number of panicles m-2,length of panicle, fertile grains panicle-1 and test weight resulting in the maximum grain and straw yield of the rice-rice cropping system followed by application of RFD+Zn-EDTA @1kg ha-1+S @ 30 kg ha-1+B @1kg ha-1. Application of RFD+ZnSO4+B recorded highest gross return, net return and B: C ratio over other management practices.
