GRAIN YIELD AND YIELD COMPONENTS OF TRITICALE UPON APPLICATION OF DIFFERENT FOLIAR FERTILIZERS

摘要

Field experiments were conducted in the growing seasons of 2000-2001 and 2001-2002 to investigate the effects of various commercial foliar fertilizers containing N, P, K and micro nutrients on yield and yield components of triticale. Yield and yield component values were different among years because of dry season. The results revealed that foliar treatments had significant positive effect on grain yield, spikelet number per spike, number of grain per spike, 1000 grain weight and harvest index in both years. The most effective foliar fertilizer on yield and yield components during drought stress was Zn-15, a chelated (EDTA) form of zinc. Both NZN and ZnSO_4 increased grain yield of triticale under no stress conditions.
