An experiment was conducted during winter season of 2009-10 on sandy clay loam soils of Students’ farm, College of Agriculture, Acharya N. G. Ranga Agricultural University, Rajendranagar, Hyderabad to find out the Effect of different varieties and levels of nitrogen on Growth functions wheat (Triticum aestivum L.) The treatments consisted of three varieties (HP 4080, RAJ 4037 and HI 8682) and four nitrogen levels (0, 60, 120 and 180 kg N ha-1). The experiment was laid out in randomized block design with varieties as first factor and nitrogen levels as second factor with three replications. The findings of experiment are summarized below. Crop growth rate was maximum between 60-90 DAS and maximum for variety RAJ 4037 and at 180 kg N ha-1 among all the levels of nitrogen. Relative growth rate and net assimilation rates were found maximum between 10-30 days after sowing. Leaf area duration was maximum with RAJ 4037 among the varieties and 180 kg N ha-1 produced higher Leaf area duration. Among the varieties RAJ 4037 produced highest grain yield with 180 kg N ha-1.
