Purpose. To elaborate winter wheat cultivation technologies based on balanced fertilizer system that combines application of mineral fertilizers and the increase of their efficiency by the use of preparations with microelements.Methods. Field and laboratory studies, mathematical and statistical analysis.Results. During 2011–2013, the effect of cultivation technologies on the formation of yield and quality of winter wheat varie­ty ‘Benefis’ (pea is a predecessor) was studied. In case of alternative technologies that provided adding only by-products of the predecessor, the yield of winter wheat was 3.73 t/ha when using integrated protection system, and it was increased to 4.22 t/ha with grain quality of the 4th–5th class of the group B when foliar dressing was applied. Resource saving technologies of cultivation with restricted use of fertilizers (Р45К45N30(II)+30(IV)) provided productivity at the level of 5.19–5.61 t/ha with grain quality of the 2nd–3rd class of the group A. Grain yield of 6.27 t/ha of the 2nd class quality was obtained by the use of intensive cultivation technology, which included application of mineral fertilizers (Р90К90N30(II)+60(IV)+30(VIII)) in addition to the use of predecessor’s by-products and foliar dressing. The highest yield of grain (6.71 t/ha) on average during all years of the study with the 1st class of the group A quality was provided by energy-intensive technology, which included application of P135K135N60(II)+75(IV)+45(VIII) with embedding of predecessor’s by-products into the soil and foliar dressing.Conclusions. It was established that in the northern part of the Forest-Steppe zone of Ukraine the highest productivity of winter wheat was obtained in dark gray podzolic soils using the energy-intensive technology with application of P135K135N60(II)+75(IV)+45(VIII) against the background of predecessor’s by-products embedded into the soil in case of integrated plant protection, and foliar dres­sing. This technology ensured the yield of 6.71 t/ha with grain quality of the 1st class of the group A.

Purpose. Improve adaptive technologies for growing winter wheat, which will ensure the planned stem density and the productivity of the ear, what will allow forming the maximum yield with high grain quality. Methods. Field, laboratory stu­dies, mathematical and statistical analysis.Results. During 2011–2015 the process of forming the productivity of winter wheat ‘Benefis’ variety with various cultivation technologies was monitored. In particular, indicators of the stem density, the number of initiated flowers, spikelets and grains in the ear, their reduction according to the stages of organogenesis, the potential yield of winter wheat and the degree to which it is actually realized are given. It was revealed that such elements of cultivation technology as doses of fertilizers, plant protection system positively influenced the density of the productive stems from the IV to XII stages of organogenesis. The largest number of preserved stems (695 pcs./m2) before the XII stage was noted in the variant with the introduction of Р135К135N60(II)+N75(IV)+N45(VIII) against the background of precursor by-products and in the case of integrated protection.The implementation of productive stems under these conditions was 41.3% quantity of the loss of stems from the IV to XII stage of organogenesis ranged from 657–986 pcs./m2 depending on doses of fertilizers and a protection system. The number of flowers (grains) in the ear from the V to the XII stage changed depending on the nutritional conditions of the plants and enhanced with increasing doses of fertili­zers in the ear of both orders. By the number of flowers per spike, integrated protection had an advantage over the minimum. The largest number of flowers from stage V to IX was received for introducing P135K135N60 (II) + N75 (IV) + N45 (VII) against the background of by-products of the predecessor and in the case of integrated protection.Conclusions. It was found that in the conditions of the northern part of the Forest-Steppe of Ukraine on the dark gray podzolized soil, the highest productivity of winter wheat was obtained by intensive energy-saturated cultivation technology with the introduction of Р135К135N60(II)+75(IV)+45(VIII) on the background of by-products of the precursor system and in the case of integrated protection.

Results of study focusing on impact of environmental factor – time of spring vegetation renewal (TSVR) of soft winter wheat on growth and development of plants, crop productivity and modern varieties response are presented. It is found that in the central part of the Right-Bank of Forest-Steppe of Ukraine this factor is important and it should be considered in planning of spring and summer care techniques, fertilizer system, especially at spring fertilizing, use of pesticides and growth regulators, in taking a decision on reseeding or underseeding of space plants. At the same time, it was determined that the environmental effect of TSVR was not occurred every year, thus it is not always possible to forecast the type of plant development. But in such years it is possible to influence the processes of plants growth, development and survival in spring and summer periods and the formation of their productivity by introducing such intensive technologies as differential crop tending, mineral nutrition optimization, the use of plant growth regulators, trace nutrients, weed, pest and disease control agents.

Purpose. To determine the effect of the basic organo-mineral fertilizer on the formation and stability of grain quality of winter wheat varieties in multiple crop rotation after black fallow as a predecessor. Methods. Field experiments were based on a multifactorial scheme using split-plot method with due regard to all requirements of the field experiment procedure, analysis of variance was used for statistical processing of the obtained results. Results. Investigation data was given concerning determination of grain quality indices in winter wheat varieties of diffe­rent ecotypes after black fallow as a predecessor depending on organo-mineral fertilizer application in the Left-Bank Forest-Steppe zone of Ukraine. In average for the period of investigation (2011–2015), the highest protein content in winter wheat grains was formed in no treatment variant [in such varieties as ‘Doridna’ (14.1%), ‘Dykanka’ (14.3%) and ‘Levada’ (14.2%)] and in case of organo-mineral fertilizer application [in the varieties ‘Hordovyta’ (14.0%), ‘Kalyta’ (14.0%), ‘Dykanka’ (14.7%) and ‘Levada’ (14.6%)]. The highest content of crude gluten in grains, without regard for the variant of the experiment, was found in the following varieties as ‘Dykanka’ (24.9–25.1%) and ‘Levada’ (23.7–25.4%). Conclusions. It was established that the content of protein and crude gluten in grains as well as the falling number of winter wheat was highly dependent on such factors as the variety and the year of cultivation as compared to the fertilizer background. The following varieties as ‘Hordovyta’, ‘Mulan’, Dykanka’ and ‘Levada’ were very sensitive to the application of organo-mineral fertilizer for the protein content, while ‘Hordovyta’ (2.4%), ‘Levada’ (1.7%), ‘Borvii’ (1.2%) and ‘Mulan’ (1.1%) – for the crude gluten content.

Elements of energy-saving technology of table beet seed production (variety type of Bordeau) in the Eastern Forest-Steppe of Ukraine were improved, they include method of irrigation (drip irrigation, HB 70–65%), fertilizing (locally N 15 P 30 K 60 + N 15), fertigation (stage of 3–4 true leaves, bundle ripeness, the beginning of stooling and flowering), the use of standard mother roots 61–100 mm in diameter along with mother rootsstecklings 41–60 mm in diameter that increase average yields according to the size up to 1,89 t/ha. It is found that the application of micronutrient mixture of Zn + B + Mo in one term and mixture of Zn + B in two terms was the most effective.

Purpose. Determination and analysis of relationship of sowing qualities and yield properties of millet seed (Panicum meliaceum L.) to be formed by the action of predecessors and conditions of mineral nutrition in the context of unstable moistening in the Right-Bank Forest-Steppe zone of Ukraine. Methods. Mathematico-statistical ones (correlation, regression). Results. The use of correlation pleiades method allowed to analyze multifactor relations of sowing qualities and yield properties of millet seed and establish that there was a direct correlation relationship of medium strength (r = 0.52 ± 0.01) between yielding of maternal and millet plants of the first seed progeny. It was found that maternal plants yielding is strongly correlated with laboratory and technological indicators of seed quality that interrelated through integrated quality parameter of seed material (r = 0.56 ± 0.01) and millet output (r = 0.98 ± 0.00). Integrated quality parameter as well as each of the studied laboratory parameters of seed material quality taken separately have a high-level (r = 0.87…0.96 ± 0.00) effect on the formation of grain yield of the first seed progeny plants. Such physical and technological parameters of the quality of maternal plants yield as a content of protein and fat in seed, seed weight, its uniformity can directly, and millet output, thousand-grain weight and hull content – indirectly indicate peculiarities of forming future grain yield of plants of the first seed progeny. Conclusions. The use of the correlation pleiades method allows to analyze objectively the sowing qualities of millet seed and predict the yield properties in the next generation.
