Abstract

The N use efficiency of low land rice was studied with the modified urea products, such as coaltar coated urea, Neem cake blended urea and urea supergranules in com- parision with prilled urea as basal and in splits Neem cake blended urea was significantly superior to coaltar coated urea and prilled urea. Urea super granules in placement record ed the highest gross return at both the levels of N and was significantly superior to all other sources. When comparing the prilled urea, at 75 per cent of the recommended level of N as urea super granule in placement was significantly superior to 100 parcent level of N as Prilled urea and indicating a saving of 25 per cent N.
