ارزیابی اثر مدیریت بقایاء و روش‌های خاک‌ورزی بر ویژگی‌های کیفی عملکرد سویا

Oilseeds are of high value agricultural products, which play major role as a supplier of raw material resources and needs cleansing oils, fats, proteins, vitamins in living organisms. To evaluate the effect of tillage systems and crop residue management and soil microorganism’s activity and soybean yield and quality in Gorgan, experiments were carried out in strip plot based on randomized complete block with three treatments and three tillage systems on crop residue management in triplicate at the Agricultural Research Station of Gorgan in 2011. The results of data analysis showed that crop residue management had a significant effect on seed oil and protein at 1%. But there was no significant effect of tillage on yield and oil content of protein and protein as well as the total amount of oil. There was a significant negative correlation between oil and protein at 1%, but there was a significant positive correlation between the percentages of oil yield.
