In order to increase N use efficiency of transplanted rice in vertisol, a field experiment with medium duration rice. variety "Mahamaya" was conducted with SoU : FYM conditioned and neem based products coated urea during khari! 1997. The application of Soil : FYM : Urea (1:3:1) 2/3 as basal and remaining 1/3 atpaniCIe initiation stage of rice produced the maximum grain yield (47.78 q/ha) and N use efficiency (30.21 kg grain /kg N), which was significantly superior than priDed urea (PU), best split and PU coated with neem based products (Nimin. Nimico, Neem sona) and applied whole amount as basal. Urea coated with neem based products and applied 2/3 as basal and remaining 1/3 at PI stage found to be· equally effective as Soil: FYM : Urea (1:3:1) for grain yield of rice. Urea coated with neem based products and applied either 2/3 as basal and remaining 1/3 at PI stage or whole amount as basal, although produced similar grain yield, but N use efficiency was higher when it was applied 2/3 as ba!>al and 1/3 at PI stage.
