Field experiment was conducted to evaluate effect of planting methods and fertilization modules on the growth and yield of rice (Oryza sativa L.) in tarai region of Uttarakhand at the Norman E. Borlaug Crop Research Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, during the Kharif season of 2010-11. The experiment was laid out in randomized block design with four replications and comprising five treatments i.e. T1- conventional method of transplanting with RDF (150:60:40 kg/ha N:P2O5:K2O+0.5% ZnSO4), T2-conventional method of transplanting with 180 kg N+Sesbania green manuring and recommended phosphorus, potassium and 0.5% ZnSO4, T3-conventional method of transplanting with 10% extra RDF (165:66:44 kg/ha N:P2O5:K2O+0.5% ZnSO4), T4-direct rice seeding with recommended dose of NPK and 0.5% ZnSO4 and T5-direct rice seeding with 10% extra recommended dose of NPK and 0.5% ZnSO4.The analysis of data indicated that values of growth attributes like plant height, number of shoots /m2 and dry matter accumulation (g/m2) was maximum due to T2-conventional method of transplanting with 180:60:40 kg/ha N:P2O5:K2O+0.5% ZnSO4+Sesbania green manuring followed by T3-Conventional method of transplanting with 10% extra RDF (165:66:44 kg/ha N:P2O5:K2O+0.5% ZnSO4.Whereas, the highest straw yield (67.25 q/ha), biological yield (129.54 q/ha) and grain yield (62.39 q/ha) was due to T2-conventional method of transplanting with 180:60:40 kg/ha N:P2O5:K2O+0.5% ZnSO4+Sesbania green manuring followed by T3-Conventional method of transplanting with 10% extra RDF (165:66:44 kg/ha N:P2O5:K2O+0.5% ZnSO4 compared with other treatments. The results showed that green manuring with NPK+Zn had direct beneficial effect of growth and yield of rice.
