Effect of Foliar vs. Broadcast Application of Different Doses of Nitrogen on Wheat

摘要

In order to study the effect of foliar versus broadcast application of various nitrogen levels on the yield and yield components of wheat, an experiment was conducted at Malakandher Research Farms, NWFP Agricultural University, Peshawar during 1999-2000. Statistical analysis of the data revealed that various doses of nitrogen and their methods of application had a significant effect on plant height, days to heading, days to maturity, number of grains spike ^-1, productive tillers m ^-1, spike length, 1000-grain weight, grain and biological yield. Plant height and days to heading were maximum when nitrogen was applied at the rate of 140 Kg ha ^-1. When the effect of application method was taken into an account, it was observed that foliar application of nitrogen had a profound effect on plant height, days to heading, days to maturity, number of productive tillers m ^-1, number of grains spike ^-1, 1000-grain weight, grain yield and biological yield. Foliar application of nitrogen resulted in taller plants, heavier grain and maximum grain yield and biological yield.
