Korpita H. Productivity of spring barley and potato depending on the degree of indigestion in the western forest-steppe of Ukraine

The dissertation presents the results of research on the state of weed infestation, the water-physical properties of dark gray forest soil, the level of productivity, the quality of the harvest, and the economic and energy efficiency of agrocenosis of spring barley and potato by organo-mineral and organic fertilizer systems in the western forest-steppe of Ukraine. The productivity of test crops was the highest: for organo-mineral fertilizer system: spring barley – 7.2 t/ha f. u. in the variant of application of herbicides Lancelot, 33 g/ha + Аxial, 1 l/ha in the phase of the tube (+ 26,3 % to control); potato – 10.6 t/ha f. u. in the variant of introduction of herbicides Hesagard, 4 l/ha + Pantherа, 1 l/ha (+ 34,2 % to control); for organic fertilizer system: spring barley – 6.6 t/ha f. u. in the variant of introduction of herbicides Lancelot, 33 g/ha + Axial, 1 l/ha in the phase of the tube (+ 24,5 % to control); potato – 9.9 t/ha f. u. in the variant of application of herbicides Hesagard, 4 l/ha + Panthera, 1 l/ha (+ 32 % to control).
