Abstract:

Although area of wheat (Triticum aestivum L.) under rainfed conditions is less in North-western India but selection of appropriate variety plays an important role in the success of crop. The experiment was conducted at the Punjab Agricultural University, Ludhiana (300 54' N and 750 48' E; 247 m ASL) during winter seasons of 2009-10 and 2010-11 on loamy sand soil with low in organic matter. The experiment was laid out in a split plot design with three nitrogen levels [N 40, 60 and 80 kg N/ha] as main plot treatment and four wheat varieties (C 306, PBW 175, PBW 396 and WH 1080) as subplot treatments with three replications. The grain yield recorded in 60 and 80 kg N/ha was 28.5 and 38.5% higher than that recorded in 40 kg N/ha, respectively. But lower dose of nitrogen (40 kg N/ha) had significantly higher nitrogen use efficiency than other doses of N application. Rainfed wheat variety, PBW 175 recorded the highest grain yield and nitrogen use efficiency which was significantly higher than WH 1080, PBW 175 and PBW 396.
