The high gain of a crop was provided with entering at crop Р10. Thus the gain of productivity has made 2,1-5,9 centner/h, and a level of profitability of 78-108 %. Also a high gain of a crop on hybrids Siver and Kharkov 49 has provided radical N30, a gain 2,1-5,9 centner/h, but the level of profitability was a little bit lower than 50-92 %. Processing of seeds and plants of sunflower reakom has allowed to receive an increase of a crop on hybrid Siver - 1,8 centner/h, and on a hybrid Kharkov 49 - 2,3 centner/h. Processing of seeds and plants and their sharing has not provided with molybdenum of reception of an essential gain of a crop of sunflower. Entering of herbicide on crops of hybrids of sunflower has essentially affected reception of a gain of productivity on 2, 6-2,7 centner/h at НСР05 1,2 centner/h. Thus the tendency to decrease on 2 % and increase of contents of oil on 0, 4-1,0 % was observed. For hybrid Siver optimum density makes 60 thousand/h with a width 45 sm and 70 sm, and for a undersized hybrid Kharkov 49 it is expedient to narrow to 45-30 sm, and density thus needs to be increased up to 80 thousand/h.
