چکیده مقاله :

به منظور ارزیابی تاثیر تاریخ کاشت روی عملکرد و اجزا عملکرد ارقام سویا یک آزمایش در شهرستان سلماس در سال 1390 اجرا شد. فاكتور اول، تاريخ كاشت در چهار سطح شامل 25 ارديبهشت، 10 خرداد، 25 خرداد و 10 تیر و فاكتور دوم، رقم در سه سطح شامل ويليامز، L17 و زان در نظر گرفته شدند. صفات مورد اندازه گيري شامل، وزن صد دانه، تعداد نیام در بوته، تعداد دانه در نیام ، تعداد انشعاب در بوته، درصد روغن و عملكرد دانه بودند. تجزيه واریانس داده ها نشان داد كه اثر تاريخ كاشت بر وزن صد دانه، تعداد نیام در بوته، تعداد دانه در نیام ، تعداد انشعاب در بوته، درصد روغن و عملكرد دانه معني دار بود و با تأخير در كاشت همه صفات اندازه گيري شده كاهش يافتند و بیشترین عملکرد دانه به میزان 4/333 گرم در مترمربع در تاريخ كاشت 25 ارديبهشت ماه مشاهده گردید. اثر رقم نیز بر صفات مورد آزمون به غير از تعداد دانه در نیام معنی دار شد و بیشترین عملکرد دانه به میزان 4/235 گرم در مترمربع از رقم زان حاصل شد.

چکیده انگلیسی:

To evaluate the effect of planting date on the yield and components of soya variety, an experiment was carried out in 1390 in Salmas. The first factor, the planting date, was assigned in four levels: Ordibehesht 25th and Tir 10th; the second factor was the cultivar in three levels: William, L17, and Zan. The measurable traits included: weight of 100-grain, number of pods in the shrub, number of grain in the pod, number of offshoots in the shrub, oil percentage and grain yield. The analysis of date variance showed that the impact of planting date on the weight of 100-grain, the number of pods in the shrub, number of grain in the pod, number of offshoots in the shrub, oil percentage and grain yield were meaningful. All the measured traits were reduced with delay in plantation, and the utmost grain yield appeared in Ordibehesht 25th plantation for 333.4g per square meter. The effect of cultivar on the tested traits, except the grain number was significant and the highest grain yield, 235.4g per square meter was allocated to Zan variety.
