Abstract

An important task of modern agricultural products is the artificial regulation of the growth and development of cultivated plants in order to increase biological productivity and improve the quality of environmentally safe products. The use of natural growth promoters and bacterial agents is quite relevant and effective. Field research was conducted on the basis of the research farm «Agronomichne» in the Vinnitsa national agrarian university in the village of Agronomics of the Vinnytsa district of the Vinnytsia region. The peculiarities of growth and development of white lupine plants are investigated. Established the positive effect of the combination of inoculation with the bacterial drug and growth stimulator on the productivity of white lupine, which is important for the formation of high and stable crop. The article presents the results of studies on the effectiveness of pre-planting and extra-root feeding in the conditions of Right-bank Forest-Steppe Ukraine on the functioning of the assimilation apparatus of white lupine plants. It has been established that bacterial preparations and growth stimulants increase the productivity of white lupine at the expense of optimization of the investigated technological methods of cultivation. The optimal area of the leaf surface has been determined, which ensured maximum grain yield. The research has established the positive effect of pre-sowing seed treatment with the bacterial drug Risogumin and the stimulator of growth of Emistim C and extracorporeal feeding of Emistim C on the content of chlorophyll in the leaves of white lupine. The influence of the investigated technological methods on the formation of the area of the assimilation surface and the synthesis of chlorophyll in the leaves of white lupine have been proved. The investigated drugs induce intensive development of the photosynthetic apparatus, increase of yield, improvement of the structure of the crop and improve the quality of the grain in the conditions of right-bank forest-steppe of Ukraine. In the region, the question of seeding bacteria and the use of growth promoters requires a more detailed study. Given this, conducting such research is important both in practical and scientific sense.
