Effect of different levels of Nitrogen and seed rates on growth and yield of nontraditional crop wheat (Triticum aestivum) in Telangana

An experiment on effect of different N levels and seed rate on wheat crop was conducted during rabi seasons of 2010-11 and 2011-12 at Agricultural Research Institute, Rajendranagar, Hyderabad Telangana. The experiment was laid out in Randomized Block Design with factorial concept (FRBD) at three different seeding rates of 100, 125 and 150 kg ha-1 and three nitrogen levels of 120,180 and 240 kg N ha-1. Two years pooled data indicated that significantly more number of tillers and panicles recorded in 125 kg seed rate ha-1 than 100 kg ha-1 and on par with 150 kg ha-1. Accordingly, 125 kg seed rate ha-1 recorded significantly higher grain yield (3084 kg ha-1) than 100 kg ha-1(2688 kg ha-1) and statistically similar with 150 kg ha-1 (3054 kg ha-1). Grain yield and yield attributing characters did not differ significantly among different N levels. Interaction effect showed that wheat at 125 kg ha-1 in combination with 240 kg N ha-1 obtained higher grain yield (3823 kg ha-1) which was on par with most of the treatments combinations.
