| Title : | RESERVES FOR INCREASING THE YIELD OF SUNFLOWER SEEDS IN THE UKRAINIAN STEPPE |
| Abstract : | The highest yields of sunflower hybrids are provided when plants are placed after surface plowing and chiseling at a depth of 25-27 cm. Reducing the depth of cultivation to 10-12 cm and direct sowing in untreated soils leads to a significant decline in sunflower yield by 20-30%. An important factor in increasing the crop yield is the use of fertilizers (N40Р60К30), which is better during the basic soil treatment in the autumn or under pre-sowing cultivation, which provides an increase in the yield of seeds at a level of 0,2-0,4 t / ha. High efficiency in the technology of sunflower growing is also provided by the use of physiologically active substances.The yield increasing from their application varies within 0,09-0,32 t / ha or 3,2-10,4%. |
