Effect of stabilized-n fertilizer (SNT) use on yield attributes, yield, nutrient uptake and quality of wheat (Triticum aestivum L.)

摘要

Field experiments were conducted during rabi 2010-11 and 2011-12 with wheat as a test crop using different SNT urea at Fertilizer Research Station, UttariPura of Chandra Shekhar Azad University of Agriculture & Technology, Kanpur. The present work wasundertaken to study the effect of different SNT urea on yield, nutrients uptake and quality of wheat (PBW-343). The use of different SNT urea (46%) at 100% local rate significantly increased grain and straw yield of wheat over T_3. Urea (46%) at 100% local rate highest yield grain 5460 kg/ha and straw 9349 kg/ha were recorded with urea (46%) SNT-C (46%) at 100% local rate.The yield attributes increased with the use of different SNT urea over plain urea and highest value was noted with T_6. The NPK uptake and per cent protein in wheat grain also significantly increased with the application of different SNT urea over plain urea and higher values were recorded with T_6.
