The aim of this research was to develop a model of productive agrocenoses of spring barley through the application of the growth regulators Biroduks, Vitazim, Emistim and Ribav-Extra. Spraying the plants with the growth regulators led to better growth and the development of leaf blades: the leaf area on one plant increased 1.2-1.74 times. The activation of photosynthetic activity using biological products was established. The most developed assimilation apparatus of the plant was developed under the drug Emistim: the leaf area was 69.224 m2 / ha. The weight of 1000 grains was at its maximum under the influence of Emistim (45.9 g). Less heavy grain was formed by crops under the influence of the Biroduks preparation (45.7 g). In version three, the weight of 1000 grains exceeded the control by 1.9 g. In version five, the increase was 1.4 g. The relationship between the mass of 1000 grains, productive bushiness and yield was a weak straight line (r = 0.19 and r = 0.16, respectively). The increase in yield depended to a greater extent on the number of preserved plants for harvesting (r = 0.98) than on the mass of the grain, the bushiness or the number of grains in the ear. The minimum biological yield was obtained in the control variant and the maximum was with the drug Emistim. Reliability at a 95% significance level was noted on all options. The positive impact on overcoming stressful effects during the growing season of spring barley was most effective when using the drug Emistim.

The research was aimed at studying the effect of biological products during barley vegetation, to assess the feasibility of their use. The paper presents empirical data on the influence of biological products on barley development, photosynthetic activity, productivity and profitability of production. During the years of the experiments, the temperature regime, distribution and amount of precipitation differed from long-term ones. When using Emistim, barley formed the largest leaf area on the plant (186.9 cm2), which exceeded the control by 223%. Plant survivability ranged from 70.9 to 77.9%. Productive tilling capacity increased by an average of 5-10% in comparison with the control. Treatment of plants with Binoram and Emistim made it possible to form an average of 1.34 productive stems per plant, Vitazim and Biodux - 1.33. The plants formed proper grain (from 44.6 to 46.2 grams of 1000 grains) under the influence of the biological products. Biodux and Binoram brought the opportunity to obtain a mass of grains 2.4 g more than the control. The relationship of productive tilling capacity, weight and yield is strong straight. The correlation of grain in an ear and yield is a strong straight r = 0.917. The increase of barley yield under the influence of biological products is associated, in priority, with the productive stalk (r = 0.959), and not with the grain weight. The highest biological yield was obtained under the influence of Emistim - 3.76 t / ha, which exceeded the control by 1.03 t / ha. Reliability at 95% significance level was noted in all variants. On average, over the years of the experiments, it is most profitable to use the growth regulator Biodux (73%) during the growing season.

As a result of the conducted in 2016–2018 studies on the study of the features of photosynthetic activity of the Ratnik hybrid sunflower found that the indicators of the leaf area of one plant and one hectare changed under the influence of the use of mineral fertilizers and growth regulators and were large according to the classical system of basic tillage. The largest indices of the leaf surface area of one plant in all systems of basic tillage were noted with the introduction of full fertilizer N60P60K60. The use of growth regulators in all combinations resulted in an increase in leaf area per plant and per hectare. Large indices of net productivity of photosynthesis were noted in crops according to the classical system of basic tillage, which were, depending on the scheme of drug use: on the control (without fertilizers) – 5,95–6,16 g/m2 × day, in variants with the introduction of N40 – 6,31–6,56 g/m2 × day, in variants with the introduction of N40P60 – 6,25–6,47 g/m2 × day in the variants with the introduction of N60P60K60 – 6,29–6,42 g/m2 × day. The application of mineral fertilizers in various doses contributed to an increase in the net productivity of photosynthesis: according to the classical system by 0,31–0,44, according to the moldboard-free system by 0,02–0,24, at the minimum 0,01–0,08 g/m2 × day. The most favorable conditions for the formation of productivity by sunflower plants have developed according to the classical system of basic tillage with a yield depending on the dose of fertilizers and the option of using growth regulators 2,62–3,46 t/ha. The highest yields of the Ratnik hybrid sunflower – 3.46 and 3.45 t/ha, were obtained when growing according to the classical system of basic tillage, applying mineral fertilizers in a dose of N60P60K60 for pre-sowing cultivation of the second and fifth options for using growth regulators: 2. Rost-concentrate + Chelatin oilseeds (6–8 pairs of real leaves) 5.1 processing: Chelatin phosphorus-potassium + Chelatin мultimix + Chelatin mono boron (3–4 pairs of real leaves), 2 processing: Chelatin mono boron (6–8 pairs of real leaves). The formation of the crop was largely influenced by the system of basic tillage (r = -0.66) and the use of mineral fertilizers (r = 0.61) and the weak use of drugs (r = 0.17). It should be noted the close relationship between yield and leaf surface area (r = 0.78), CPF (r = 0.78), dry matter weight per plant (r = 0.99) and seed weight (r = 0.97 ). Key words: sunflower, system of basic tillage, mineral fertilizer, growth regulator, leaf area, net productivity of photosynthesis, yield.

Abstract Models for estimating leaf area of bananas found in the literature are not suitable for lanceolate type leaves occurring at the vegetative stage of ratoon suckers dependent of mother plant. The objective was to determine equations for estimating the leaf area of ‘Prata-Anã’ and ‘BRS Platina’ banana plants with lanceolate type leaves. 212 and 164 lanceolate type leaves having 10 cm-wide lamina or less were collected from ‘Prata-Anã’ and ‘BRS Platina’ banana plants of 90 days of age or less, respectively. Width (W), length (L), width/length ratio (WLR), and scanner-measured leaf area (LAscanner) were determined. Using the backward elimination procedure, simple and multiple linear regression equations were fitted to the relationship between leaf dimensions (W, L and WLR) and LAscanner. To evaluate how precise the equations are in predicting leaf area (LApredicted), Pearson correlation coefficients were calculated between LA and LApredictedscanner. The models highly correlated with LAscanner at 1% of significance level. The models are and LALL() = Prata-Anã = - 0,0133624 + 0,000489859**L - 0,00183182 **W and LALL(Platina) 0,00237026 + 0,004781**W - 0,096802** WLR.

Today, an increase in the real potential of grain crops, including spring barley, is a necessary condition for elements of crop cultivation technologies. Therefore, given the limited resource potential of spring barley crops, their fastidiousness to the soil, considerable attention should be paid to the photosynthetic potential of plants and the standardised application of mineral fertilisers. The aim of the study was to improve the elements of the technology of growing promising varieties of spring barley by establishing the mineral nutrition effect on the photosynthetic activity of plants in the conditions of the Luhanska Oblast. This study provides examples of improving some technologies for growing promising varieties of spring barley and determines the optimal norms for applying mineral nutrition to ensure the high photosynthetic potential of these plants in the climatic conditions of the steppe zone of Ukraine. It was found that the use of ammonium nitrate had a positive effect on the leaf area, increasing it by 1-2.2 thousand m2 /ha compared to the control for all varieties studied. The combined use of diammonium phosphate and ammonium nitrate contributed to an increase in the leaf area by 2-4. 4 thousand m2 /ha compared to the control variant. Simultaneous application of ActiBION increased the total leaf area for all samples studied by 3.8-6.4 thousand m2 /ha. The best indicators among the studied varieties were observed on the six-row variety Helios and the double-row variety Stalker. The six-row variety Vakula and the two-row variety Adapt showed slightly lower results. Further research implies the study of the influence of photosynthetic activity of promising varieties of spring barley on crop productivity in the steppe zone of Ukraine. The findings can be recommended for production as one of the elements in the technology of growing spring barley in the climatic conditions of the Luhanska Oblast

Undercrop cultivation of alfalfa is economically justified, since in the year of sowing, cover crops give a full harvest, and also one mowing of alfalfa for hay is carried out, moreover the special preparation of the soil for grasses is not re-quired. In the conditions of the Middle Volga region, the experiment was laid on leached chernozem in 2017 - 2019, where they studied the sowing of variegated alfalfa under the crops of spring wheat, barley, oats, harvested for grain and an-nual grasses - for green fodder, and studied the options for coverless sowing, where the weeds were mowed twice and the herbicide Pivot was applied at the beginning of alfalfa branching. The total biological yield is determined by the leaf area and its photosynthetic activity. Therefore, the purpose of the research is to determine the indicators of alfalfa photosynthetic activity for an objective as-sessment of the influence of cover crops on their forage productivity. It has been established that a more intensive increase in the assimilation surface of alfalfa in the first year of life to 31.6 and 30.6 thousand m2 /ha occurs on coverless sowing with the application of the Pivot herbicide and two-fold mowing of weeds. The dry matter yield was 2.1 and 2.0 t/ha, respectively. A decrease in the illumination of alfalfa plants sown under crops, where the leaf area did not exceed 13.0...15.3 thousand ? m2 / ha, slowed down the photosynthesis processes. Moreover, a more intensive growth of its photosynthetic organs was noted under the crop of barley, the cereal-legume mixture reduced the leaf area by 0.5 thousand m2 /ha, the pho-tosynthetic potential was 898...1051 thousand m2 day/ha.
