The influence of various methods of weed control on the productivity of sunflower hybrids |
|
|
Hence the researches it has been found that the using herbicides Euro-Lightning, Euro-Lightning Plus and Express on resistant to these products hybrids can be considered an effective method of sunflower cultivation technology. It significantly increases the yield of this crop and has maximum economic efficiency. On average for two years of study the using herbicide Euro-Lightning at a dose of 1.2 l/ha contributed to the oilseed yield gain compared to the control 1.29 t/ha (155.4 %). When applying the herbicide Euro-Lightning Plus at a dose of 1.6 and 2.0 l/ha, the oilseed yield gain noted compared to the control 1.40 and 1.36 t/ha or 168.7 and 163.9 %, respectively. When applying the herbicide Express at a dose of 0.045 kg/ha, the yield of oilseeds increased up to 1.27 t/ha (153.0%) compared to the control.
