Effect of different levels of nitrogen on the economic yield of Wheat (Triticum aestivum L.) variety Aas-11

The present study was planned to determine the effect of different levels of Nitrogen on the economic yield of wheat (Triticum aestivum L.) variety Aas-11. Thus, an experiment was carried out in the research area of Regional Agriculture Research Institute Bahawalpur (RARI) during 2013-14 to test the effect of various Nitrogen levels on the yield and yield component of wheat. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. Nitrogen levels i.e, 0, 30, 60, 90, 120 and 150 kg/ha were tested in this study. The results revealed that 120 and 150 kg/ha levels of nitrogen fertilizer significantly increased the fertile tillers, plant height, spike length, number of spikelet per spike, number of grains per spike, 1000 grain weight, grain yield per plot and grain yield kg/ha. The application of nitrogen fertilizer was found to be most effective for enhancing the quantitative and qualitative growth of wheat.
