Frequency of Various N Levels, Lodging and Seed Quality in Wheat
Zia- ul- Islam, Sherin Khan , Jehan Bakht and Wajid Ali Shah

Abstract:
The study was conducted to determine the frequency of various N levels, lodging and seed quality in wheat, at Malakandher Research Farms, NWFP Agricultural University, Peshawar, during 2000. Statistical analysis of the data revealed that various levels of nitrogen had a significant effect on all parameters except seed vigor. Plots fertilized with 170 kg N ha-1 had maximum productive tillers m-2, spikelet spike-1, grains spike-1, grain yield and harvest index. Whereas minimum biological yield was recorded in plots fertilized with 200 kg N ha-1. Nitrogen levels of 140 kg ha-1 significantly increased germination %age and seed size by weight. In case of nitrogen application frequencies, plots applied with nitrogen in 2 split doses i.e., 50 % at seeding time and 50 % at 2nd irrigation significantly increased number of productive tillers m-2, spikelets spike-1, grains spike-1, grain yield, harvest index, germination % age and seed size by weight. However, nitrogen applied in full at 2nd irrigation recorded maximum biological yield.
