Abstract
A field trial and a laboratory experiment were conducted during 2011/2012 and 2012/2013 seasons. The main objective of this research was to study the performance of some wheat cultivars as affected by sowing dates and seed treatments and their effect on growth, yields and its components and seed quality. Each sowing date (10th November, 25th November and 10th December) was practiced in separate experiments. Every experiment was carried out in split-plot design with four replications. The main plots were occupied with wheat cultivars (Sakha 93, Sakha 94 and Gemmiza 10). The sub-plots were assigned to seed treatments (without seed treatment, treated seed with fungicide Vetavax and soaking seed in the mixture of Fe + Zn).
Results showed that early sowing date (10th November) markedly resulted in the highest values of growth, yields and its components, shoot and root length and seedlings dry weight. Whereas, sowing on 25th November came in the second rank and resulted in the highest values of germination % and speed of germination. While, delay sowing wheat up to 10th December came in the last rank and resulted in the highest values of protein %.
Gemmiza 10 cultivar surpassed other studied cultivars (Sakha 93, Sakha 94) and recorded the highest values of flag leaf area, spike length, number of grains/spike, grains weight/spike, 1000-grain weight, grain yield/fed, speed of germination, and seedlings dry weight. While, Sakha 94 cultivar recorded the highest values of plant height, number of spikes/m2, straw yield/fed, shoot and root lengths. However, Sakha 93 cultivar recorded the highest values of protein % and germination %.
Soaking wheat seeds before sowing in the mixture of Fe + Zn surpassed other studied seed treatments and resulted in the highest means of all studied characters. Treated wheat seeds with fungicide "Vetavax" followed by aforementioned treatment.
It can be concluded that, sowing Gemmiza 10 cultivar on 10th November and treated its seeds before sowing with mixture of micronutrients (Fe + Zn) could be recommend to maximize wheat productivity and quality of grains and seeds under the environmental conditions of Dakahlia Governorate.
