This study was conducted during two crop seasons to investigate the effect of nitrogen fertilizer quantity and application form on grain yield and quality in Eskisehir Transitional Zone Agricultural Research Institute by using seven bread wheat cultivars in rainfed and eight in irrigated conditions. In the study, urea as a source of nitrogen was applied in heading time (Zadoks 59) in granular and foliar form. In all treatments grain yield, some technological quality characteristics were determined of the genotypes. In both conditions while sedimentation value, protein content, aggregation energy (AGGEN) and maximum torque (BEM) values increased, peak maximum time (PMT) decreased with foliar urea applications. it was determined that there were statistically significant differences between the varieties in terms of SDS sedimentation values in both rainfed and irrigated conditions. In this study, In irrigated and rainfed conditions the values obtained from foliar urea applications compared to granular ones with relation higher bread quality in the genotypes which contain Glu-A1 locus 2* subunit; 9% for grain yield, 6.5% for protein content, 17.0% for sedimentation value and 3.8% increase of BEM, Glu-D1 locus; 5+10 subunit 8% for grain yield, 5.6% for protein content, sedimentation 16.0%, 6.4% for BEM increase, for Glu-B1 locus; 7+9 subunit 7.0% for grain yield, 6.0% for protein content, 19.6% for sedimentation value, and 7.2% for BEM value increase. This study was observed that the foliar application during the heading time provided the improvement of bread wheat grain yield and quality characteristics.

Short periods of high temperature (> 35�C) are common during the post-anthesis period in Australian wheat crops and have recently been shown to significantly reduce grain yield and quality. In view of this, 75 cultivars of wheat were screened for tolerance to 3 days of high temperature (max. 40�C). Detailed results for grain yield and quality are presented for five wheat cultivars in order to illustrate the wide range of responses to short periods of high temperature. Individual kernel mass decreased by up to 23%, depending on variety, and the gliadin : glutenin ratio altered in the range -9 to +18% in response to high temperature treatment, also depending on variety. Noodle swelling power was significantly affected by heat in two cultivars, but there was no significant change due to heat in the apparent amylose content in any variety. The marked response of several yield and quality components to a heat treatment lasting only ca 5% of the grain-filling period suggests that starch and protein synthesis do not immediately andlor fully recover from short, severe heat stress. In addition, we conclude that wheat shows considerable genetic variability in tolerance to short periods of high temperature for both grain yield and quality.
