An experiment was conducted at research farm of Rajendra Agricultural University, Pusa (Samastipur), Bihar during rabi season of 2003-04 with four sowing dates i.e., 27th November, 11th December, 25th December and 8th January along with four test varieties i.e., K 9107, PBW 343, HP 1744 and NW 1014 under split plot design to find out suitable sowing time for newly released wheat varieties under irrigated condition of Bihar and their economics of production. It was found that delay in sowing beyond 11th December drastically reduced the grain yield to the tune of 47.5 and 70.6 per cent, respectively when sown on 25th December and 8th January with respect to normal sowing on 27th November. Among varieties, K 9107 and PBW 343 achieved significantly higher grain yield than HP 1744 and NW 1014 varieties. Net return and B:C ratio were also significantly higher when wheat was sown on 27th November and followed by 11th December. Beyond 11th December, it registered 334 and 337 per cent decrease in net return/ha. Sowing of wheat on 8th January was found uneconomical. Wheat varieties K 9107 and PBW 343 were found suitable for irrigated condition of Bihar.
