WHITE LUPIN SEEDS YIELD (LUPINUS ALBUS L.) DEPENDING ON HERBICIDAL EFFECT

Abstract

Due to small amount of scientific publications on the herbicidal effect on sowing qualities of lupine seeds and almost complete lack of data on their effect on yield properties, it is relevant to carry out such studies. The research objective was to determine the peculiarities of the formation and implementation of sowing qualities and yield properties of seeds of white lupine varieties depending on herbicides use under the conditions of the right-bank zone of the northern forest-steppe of Ukraine. The research methodology included the use of field, laboratory and statistical methods. Research results allowed to establish that white lupine plants on weedy grown areas (without crop weeding and herbicides) turned out to be the least productive – 65.6 % (Serpnevyi variety) and 67.7 % (Chabanskyi variety). The highest seed yield among variants with herbicides use showed that the usage of Harnes and tank mixture of Prometrex + Jupiter (Serpnevyi variety – 3.50 and 3.49 tons/ha, Chabanskyi variety – 3.83 and 3.87 tons/ha respectively). Herbicides use while sprouting period negatively affected yield formation – it was the lowest among herbicide variants and was 2.80 and 2.75 tons/ha in Serpnevyi variety, and for Chabanskyi variety it was 3.03 and 3.06 tons/ha. On the plots of these variants, there was also growth and developmental delay of lupine plants, which was especially observed in the first half of the vegetation
