 ABSTRACT

A field experiment was conducted at Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa- Bihar during kharif 2015 to assess the effect of nitrogen scheduling on yield and yield attributing characters in rice under different establishment methods in split plot design. The factors under study comprised the effect of nitrogen scheduling viz. LCC based and splitting of N along with slow release N fertilizer and crop establishment methods viz. transplanting, direct seeded rice (DSR) dry and wet.  Among different rice establishment methods, transplanting method registered the maximum grain yield  (39.11 q ha-1) which remain comparable to DSR-wet. Under different nitrogen scheduling, LCC-4 recorded maximum grain yield (44.12 q ha-1) and it was significantly superior to rest of the treatments except neem coated urea. However, an appraisal of data indicated that different rice establishment system didn’t produced significant effect on yield attributing characters of rice. With regard to nitrogen scheduling yield attributing characters was significantly superior over the control. The maximum, test weight was recorded under N5 – NCU (100% B) (21.63 g), harvest index N5 – NCU (100% B) (43.01 %), number of panicles m-2 LCC-4 (252), number of grains panicle-1 N2 – LCC-4 (117), panicle length N2 – LCC-4 (27.83 cm), panicle weight N2 – LCC-4 (2.82 g) and grain weight panicle-1 N2 – LCC-4 (2.51 g) during the experiment.

Key words: Nitrogen scheduling, Transplanting, Direct seeded rice, Neem coated urea, LCC.
