An experiment was conducted during rabi of 2011-12. To evaluate the effect of integrated nutrient management on phenology, growth and dry matter accumulation of different parts (leaf, stem and ear head) of wheat (Triticum aestivum L.). Results showed that the application of 150% NPK took maximum days of 50% flowering (71.0 days) and days to physiological maturity (119.8 days) of wheat. The growth of wheat in terms of plant height, leaf area index, at 30, 60, 90 DAS and at harvest were observed maximum with application 100% NPK + 10 tonnes FYM ha super(-1). The study of dry matter accumulation and its distribution in various parts of wheat revealed that application of 100% NPK in conjunction with 10 tonnes FYM ha super(-1) accounted maximum partioning at different stages of crop growth after sowing which were 55.19 (at 30 DAS), 111.03 and 56.68 (at 60 DAS) percent increase in dry weight of leaf and stem over control, respectively. Furthermore this treatment resulted 191.94, 80.04, and 160.92% higher biomass accumulation by leaf, stem, and ear head at 90 DAS and 172.85, 136.76 and 220.17% higher biomass at harvest over control, respectively. The soil enrichment with 100% NPK + 101 FYM ha super(-1) attained maximum CGR (13.54 and 20.24 g m super(-2) day super(-1)) between 30-60 and 60-90 DAS, respectively. The RGR between 30-60 DAS was statistically unaffected due to different mode of nutrition, however it was significantly enhanced between 60-90 DAS with application of 100% NPK + 10 t FYM ha super(-1) and 100% NPK + S + Zn both were attained statistically at par value of RGR (0.029 g g super(-1) day super(-1)) and higher than remaining treatments.
