Most of the peoples of the world depend on rice for their secured livelihood and a way of life. It is the staple food for more than 65 per cent of the people and provides employment and livelihood to 70 per cent of the Indians. There is a need to enhance the productivity of the rice to meet the growing demand under conditions of declining quantity and quality of land (Raju, 2013). Nitrogen is a key nutrient in promoting the plant growth and determining the yield level of rice. Recovery of applied nitrogen in rice is very low owing to various losses. Optimization of applied nitrogen at critical growth stages, coinciding with the period of efficient utilization is essential to meet the nitrogen requirement of crop throughout the growing season (Pandey et al., 2002). Nitrogen management is an important aspect for obtaining good yield of rice. Optimum dose and schedule of fertilizer application is necessary to achieve higher yields, minimize lodging and damage from insect pests (DRR, 2013). Nutrition is the critical input in yield realization of rice under rainfed shallow lowland situation as availability of required nutrients is low-medium in red and lateritic areas of West Bengal.....
