Abstract

With the objectives of testing the optimum population and fertilizer combinations (NK) for getting higher yield in rice (IR.50), an experiment was conducted at wetlands, Tamil Nadu Agricultural University, Coimbatore during Kharif 1986. Population of 66 and 80 hills/m² and fertilizer combinations (N-K20 kg/ha), control (No NK), 75-50, 150-50, 150-100, 225-50 and 225-100 were tested in a split plot design replicated four times. The population of 80 hills/m² was found to increase the yield parameters and yield of rice. Fertilizer combination of 150-50 kg N K20/ha was optimum in increasing the growth and yield parameters, DMP, nutrient uptake and production of rice.
