Abstract:
An experiment was conducted at Instructional Farm, Department of Agronomy, Faculty of Agriculture, AKS University, Sherganj, Satna (M.P.) during kharif season of 2017-2018. The experiment consisted of randomize block design having Factorial arrangement in three replications. In this experiment, 12 treatment combinations including three varieties (MTU-1010, IR-64 and JR-201) and four levels of nitrogen (0, 60, 120 and 180 kg/ha). The treatments comprised three varieties (MTU-1010, IR-64 and JR-201) and four levels of nitrogen (0, 60, 120 and 180 kg/ha). It was found that variety and nitrogen significantly affected plant height, number of tillers per plant, number of tillers per plant, number of grains/panicle, thousand grain weight, grain and Stover yield of rice. The plant height, number of branches per plant were, in general, increased in all the treatments with the successive growth and development stages of crop i.e. 30, 60 and at 90 DAT stages of plant growth. Among these vegetative growth parameters, plant height, in general, enhanced at the faster between 30 days up to the 60 days stage of observations. At 90 DAT stage, plant height ranged from 85.22 to 92.57 cm and tillers 9.26 to 11.97/plant as well as effective tillers 11.26 to 12.23/plant at 65 DAT stage under different treatments. Similarly, the factor which are directly responsible for ultimate grain production viz. number of panicles/plant, number of filled grains/panicle and seed yield/plant were augmented almost significantly due to rice variety JR 201 as against IR-64 and MTU-1010. Thus, the maximum number of panicles were 10.36/plant, number of filled grain 10.40/panicle and 31.69 g seed yield/plant in case of JR-201.
