| Abstract | ||
| Two field experiments were carried out in the Research and Experiment Center of the Faculty of Agriculture at Moshtohor. Kalubia Governorate. Zagazig University during 1996197 and 1997/98 seasons to study the response of some wheat cultivars (Gemmeiza 1. Side 7. Giza 183 and Sakha 69) to different nitrogen fertilization levels {30. 60. 90 and 120 kg led). Results indicated that increasing nitrogen fertilization levels significantly increased wheat growth, yield and its components compared to the control which fertilized with 30 kg Ntfed, Nitrogen level of 90 kg ted gave the best results for most of the studied wheat character as spike length. number of spikesi‘mz. weight of spike. number of graini‘spike. weight of grainslspike. grain yield (kgffed) and protein percentage as well as lOOO—graln weight and straw yield in the first season. Such results were obtained in the two growing seasons. However, the superiority of the application of 120 kg led was noticed only with plant height and spike length in the two seasons. and straw yield per feddan in the first season. Meanwhile. nitrogen fertilization level of 60 kg led produced the highest moo-grain weight in 1996097 season only. Regarding wheat cultivars. Gemmelza 1 produced the highest values of plant height. number of spikesimz. number of grainlspike. weight of grainsfspike. grain and straw yieldsffed in the two growing seasons. While. Side 7 produced the tallest spikes, heaviest 1000-grain weight and highest protein percentage in each of the two growing seasons. On the other hand. the lowest grain yieldlfed was produced from Side 7 wheat cultivar in both seasons. Also. Sakha 69 gave the heaviest value for weight of spike in the two seasons. The interaction between cultivars and N rates significantly affected number of spikes/m2. number of grainslspike. grain yieldrfed and straw yieldifed in both seasons. ln addition. spike length. weight of spike and protein percentage were significantly affected by cultivars X N levels in the first season only. whereas of weight of grainsfspike and tOOO-grain weight in the second season. | ||
