			To ensure the achievable rice yield, adequate fertilization especially nitrogen (N) plays a crucial role in rice production. Nitrogen management for respective rice cultivars in specific paddy cultivating areas should be formulated to promote the sustainable and profitable rice production while improving N use efficiency and the environmental conservation.

Eight treatments including different rates and application methods of N fertilizer; T1 (No fertilization), T2 (0 kg N ha−1), T3 (30 kg N ha−1), T4 (77.6 kg N ha−1 as prilled urea, PU), T5 (100 kg N ha−1), T6 (130 kg N ha−1), T7 (160 kg N ha−1) and T8 (77.6 kg N ha−1 as urea super granule, USG) were laid out as randomized complete block design with three replications.
