INFLUENCE OF BUTTERS ON WATER POWER LEVELS OF SUGAR BEETS
Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 4, Issue 4
Abstract
The results of researches on determination of types of annual weeds in sugar beet crops in the conditions of the Kyiv region and the level of water absorption by plants, depending on their species, are presented. In the years of research (2015-2018), the largest volume of water absorption from the third decade of April to the second half of July was carried out by plants in sugar beet crops such as common Amaranthus retroflexus L - 37.38 l/m2, Chenopodium album L - 37.41 l/m2, Echinochloa-crus-galli (L.) Pal.Beauv - 39.44 l/m2, Setaria glauca (L .) Pal. Beauv--20.36 l / m2 and others. Experimental studies have determined that from the beginning of the vegetation to the time of formation of the maximum mass of weeds absorbed from the soil during the years of research on an average of 245,3 l/m2 of water. Such amount of water available to plants is sufficient for the formation of 58,1 t/ha of sugar beet root crops. An estimation of the competitive danger of wild plants in their ability to absorb moisture reserves in the soil in the process of vegetation and interaction of weeds and sugar beet plants is conducted.
