The results of the study conduded on secondary data from experiments on rice in Research Stations of Assam Agricultural University revealed taht the performance of N on rice can be made more mobile within the limits of 30 kg to 50 kg/ha in better environment. Similarly, the mobility of P can be assured in a better environment when applied in a dose between 30 kg/ha to 60 kg/ha. The dose 30 kg/ha could assure better result with more mobility in varying condition of environment. The treatment combinations N60P30, N80P80, N60P30K30 were found to be more mobile with hihger level of performance in changing environmental conditions. The time period third week of July for transplantation of rice was considered better for achieving mobility with higher level of production in better environmental situations. Regarding the stability of treatments, the study revealed that the levels within 30 kg to 60 kg of N, 30 kg to 60 kg P and 10 kg of K/ha on rice provided better result with average to more stability over different environments. The time period-second week of August was considered better for better yield with average stability over the environments.
