Effect of forms of urea on the yield of rice

Abstract

Field trials conducted in the farmers' fields at eight different farming situations for four seasons proved that large granule urea (LGU) is an economic and efficient source of N for low land rice, especially in areas with heavy rnonsoonic rains . LGU having no extra cost either in production or application over the ordinary prilled urea (PU) offers greater potential for efficient N nutrition in rice. The results also reveal that the entire quantity of LGU can be broadcast as a single basal dose.
