IMPACT OF CROP PROTECTION FROM THE DYNAMICS WEEDS ZABURYANENNYA INCREASE IN SOYBEAN LEAF SURFACE AND ITS PERFORMANCE
Abstract
The article shows that the growth of leaf surface and absolutely dry weight of soybean plants depends on growing conditions, but primarily - on the level of weed-infested crop and highly efficient use of herbicides in the care of the culture. Through the use of herbicides and tank mixtures Pivot Galaxy topu of poastom, leading to the reduction of weed-infested crops, there is an increase in foliage 1,5-2,1 times more compared to the control variant. Destroying weeds and improve the growing conditions of Culture accompanied by productivity growth and increase dry weight. The maximum rate of photosynthesis in soybean growing season is in the range of hilkuvannya to bloom. In version control without herbicides from hilkuvannya to flowering intensity of photosynthesis was at 5.2 g / m2 leaf area per day, while the version with Pivot - 6.9 and with the use of the Galaxy topu poastom - 6.3 g / m2 per day 33 and 21% higher than the rate in the control variant respectively.
