Özet:

Grain yield of wheat depends on plants per area, tiller per plant, kernels per spike, and weight per kernel. However only some tillers produce grain; other fail to develop a spike and die before the main stem matures and this is related to genetic factors and other environmental conditions. This research is aimed to determination of effect on different nitrogen applications to ear characters and kernel protein contents of tillers by using six different triticale genotypes (Tatlıcak 97, Melez-2001, MIKHAM-2002, Karma 2000, Samur Sorti, Presto 2000). In this experiment, differences for tillers were observed in triticale genotypes where nitrogen doses were applied during growing period of the year 2006/2007. Considering the effects of nitrogen doses for tillers, while importance of the length of ear is 5%, kernels in ear, weight of kernel, the number of ear was found 1% important. When characterization of kernel examined, 80 kg nitrogen ha-1 application on yield and thickness of kernel and protein content was found important by 1%, but the same application on width, length and thousand weight of kernel was found unimportant.
