Abstract

An experiment was carried out during rabi 2013 and 2014 under All India Co-ordinated Wheat Improvement Project, at research farm BTC, College of Agriculture & Research Station, Bilaspur (CG). Experiment was comprised of different level of seed rate (125, 150,175 &200 Kg/ha) as main plot and Nitrogen levels (80,100,120 &140 Kg/ha) as sub plot were laid out in split plot design replicated thrice with wheat variety HD 2932. Experiment is harvested and seed yield and yield attributing traits were recorded. The highest two year mean grain yield was recorded for150 Kg\ha seed rate (33.48q\ha),which was 17.02 percent higher than recommended seed rate 125 Kg/ha and 19.46 percent higher than 175 Kg/ha, lowest seed yield was recorded with seed rate 200 Kg/ha. Similar trend was also found for straw yield. This might be due to higher yield attributing character i.e. no. of tillers/sqm., number of grains/earhead and test weight (g) were recorded under seed rate 150 Kg/ha. Among four different ni
