Yield, quality and nutrient removal of wheat (Triticum aestivum) as influenced by levels and sources of fertilizer

Abstract

Response of HD 2189wheat (Triticum aestivum L. emend. Fiori & Paol.) to , different levels and sources of fertilizer was studied during the winter (rabi) season of 1993-94 and 1994-95, to investigate efficiency of 5 sources of fertilizer at 4 levels of cfertilizer in relation to yield, quality and uptake of nutrients. The grain yield, straw yield and protein content were increased significantly with the increase in levels of NPK. The yield of grain was 19.73, 30.93, 39.03 and 45.62 qlha due to application of 30,15 and 15; 60, 30 and 30; 90,45 and 45 and 120,60 and 60 kglha N, P,O, and K,O respectively. Significant improvement due to increased levels of NPK was also noticed for uptake of nutrients. There were no significant differences between the sources tried in terms of yield, protein content and uptake of nutrient, indicatingequal availability of nutrients from all sources.
