Purpose. To establish the influence of crop treatment with plant growth stimulator, microfertilizer-compensator, fungicide on the indicators of energy efficiency and competitiveness of alfalfa seed grass stands in conditions of Northern Podillya. Methods. Field experiment, calculation and weighting, mathematical statistics. The studies were carried out at the Khmelnitsky State Agricultural Experimental Station of the Institute of Feed Research and Agriculture of Podillya of NAAS during 2019-2020 on podzolized medium loam black soil. Results. The best technological methods for growing alfalfa in grass stands of the fourth-fifth year of life, which ensured an increase in the energy value of the crop, as well as energy and integral assessment coefficients, and competitiveness, were determined. The highest yields of 1.84 c/ha and energy efficiency of growing alfalfa for seeds with the highest energy value of the crop – 32.76 GJ/ha, energy efficiency coefficient of 2.51 c.u. provided a combination of treatments: plant growth stimulator Vympel (0.5 l/ha) with microfertilizer Oracle colofermin boron in the budding phase, Akanto Plus fungicide (0.5 l/ha) in the stalking and budding phases. Complex treatment with those preparations and application of double fungicidal treatment had a positive effect on the increase in the energy efficiency Ke (1.15 c.u.), integral assessment J (1.20 c.u.) and competitiveness Cmp (1.18 c.u.) coefficients. Conclusions. It was established that the growth of indicators of energy efficiency and competitiveness of growing seed grass stands was a result of the double application of Akanto Plus fungicide in the phase of stalking and budding. The energy efficiency of fungicidal treatments increased when combined with plant growth stimulator and compensating microfertilizer used in the budding phase.

Purpose. To evaluate the productivity of feed grass stands of the Sinyuha variety alfalfa according to yield indicators, quality and nutritional value of green mass harvested in the phases of budding and flowering to establish their value for the use in livestock industry in conditions of northern Podillia. Methods. Field experiment (visual and phenological observations of the growth and development of alfalfa plants), calculation, thermostatic, mathematical-statistical. Results. The studies were carried out in the field experiment of the Khmelnytskyi state agricultural research station of the Institute of Feed Research and Agriculture of Podillya of NAAS during 2019-2020 on podzolized medium loam black soil. The optimal phase of mowing alfalfa in the feed grass stands of the fourth-fifth years of life was determined. It is the budding phase, in which the feed productivity of the crop increased: the yield of green mass in the sum of four mowings, which was 2.5 t/ha or 5% higher. Despite a slight difference in dry matter content, its total yield was practically equal to that of the flowering phase. The studied phases of mowing had an impact on the feed productivity of alfalfa. It has been established that, in terms of quality and nutritional value of the leaf-stem mass, a greater accumulation of nutrients occurred during the mowing of alfalfa in the budding phase, when the gross yield of the sum of cuttings was: feed units – 8.78 t, crude protein – 2.39 t, gross energy – 151.52 GJ and exchange energy – 92.12 GJ. Conclusions. To ensure high yields and good feeding qualities of the Sinyukha variety alfalfa grass stands of the fourth-fifth years of cultivation in conditions of northern Podillia, mowing in the budding phase should be applied, what will contribute to the increase in the total yield of green mass with a slight difference in the total dry matter yield and increase in gross yield: feed units, crude protein, gross and metabolizable energy relative to the flowering phase.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
