Abstract A field experiment was conducted during 2016–17 dry season to study the relative effect of prilled and Indorama granular urea on the yield and uptake of N by maize and rice crops at varying levels of N (0, 75, 75+25FYM and 100% of recommended dose) in a factorial RBD design. Nitrogen was supplied through prilled and Indorama granular urea separately. The grain and straw yield of maize and rice increased with increasing levels of N. relatively higher yields of maize and rice were obtained when N was supplied through Indorama's granular urea. The yield obtained in 75%+25FYM of recommended dose treatment from Indorama's granular urea (GU) was at par with the yield obtained in 100% of recommended dose treatment from prilled urea (PU) in both the crops indicating 25% saving in N with GU in comparison to PU. The magnitude of increase in grain yield with GU varied from 10.9 to 15.3% in maize and 8.6 to 14.9% in rice in various treatments. The N and K uptake also showed similar trend as obtained in grain and straw yields of both the crops. These results implied that efficiency of Indorama Granular Urea was found to be higher on the yield of both the crops and 25% N might be saved using it as compared to Prilled Urea. Top |
