Study of factors affecting the yield of rapeseed hybrid in the “Viktoriia–92” farm, Ternopil district

Abstract

The challenges facing modern agriculture require the search for effective ways to grow rapeseed. These ways should contribute to innovatively increasing the yield of the studied hybrid rapeseed variety and enriching vegetable oil resources for food and technical purposes, as well as providing livestock with feed protein. Our research was conducted by studying literary sources on the specified topic and on the areas of winter rapeseed cultivation on the Victoria-92 farm. It was found that the formation of the yield of winter rapeseed seeds of the KUGA hybrid and its sowing qualities significantly depend on the type of pollination. The results of the conducted analysis of the research show that cross-pollination contributes to the positive dynamics of increasing the yield of this hybrid rapeseed. In addition to the type of pollination, the yield is affected by weather conditions in the years of cultivation, as well as a number of agrotechnical measures. For example, sowing dates, sowing methods and seed sowing rates affect plant density, their growth and development in the autumn period, as well as disease resistance and frost resistance. Morphological indicators of the KUGA hybrid indicate its yield potential. Yield showed a close correlation with indicators such as the number of pods per plant. Based on the results studied, it can be recommended to farms to grow the KUGA hybrid on their lands. Cross-pollination turned out to be the most optimal method of pollination to achieve high yields of this rapeseed hybrid.
