Abstract
The present work was conducted at the Experimental Farm of the Agriculture Research Center in Al-Azhar Univ. at Assiut, Governorate during 2016/2017 and 2017/2018 seasons to study the effect of three sowing dates (1st November, 15th November and 1st December), nitrogen fertilizer three rates (30, 50 and 70 kg N /fad.) and foliar application with boron (control, 50 and 100 ppm( on the production and quality of wheat (cv. Sids-12). The experiments were performed in a split-split plot design with replicates three, where sowing dates were assigned to the main plot, while nitrogen rates and boron were distributed randomly in the sub and sub-sub plot, respectively.The obtained results showed that sowing dates significant effect in plant height, flag leaf area, number of grains/spike, 1000-grains weight (g) and carbohydrate percentage in both seasons, except number of spikes/m2 in the second season only, as well as grain yields ton/fad in the first season only. On the otherhand, number of tillers/plant, straw yield ton/fad. and protein percentage didn't show significant effects in both seasons. In generally, sown wheat in 15- November produced the highest values in all studied traits except of 1000-grains weight (g), in the first season only from sowing on 1- December. Increasing the level of nitrogen fertilizer from 30 or 50 to 70 kg N /fad. caused a significant increases in all traits under study in both seasons, except straw yield ton/fad. in the second season only. Foliar application with boron significant increases in all studied characters, i.e. plant height, no., of tillers/plant, flag leaf area, no. of spikes/m2, number of grains/spike and 1000-grains weight (g) as well as grain and straw yields/fad. Also, such treatment increased protein and carbohydrate percentages of wheat grains.In general, the highest value of grain yield/ fad. and quality were obtained from sowing wheat on the 15th Nov. when received 70 N / fad. and boron foliar application concentration of 100 ppm under Assiut conditions.
