In the article the recommendations on autumn grain crops and rape sowing based on the newest scientific achievements are presented.

Peculiarities of winter grain crops chemical control during autumn period.

In the article data of the efficacy of nine seed dressers for protection of winter wheat against diseases are shown. The efficacy of seed dressers against seed infection with fungi Fusarium and Alternaria was high (up to 100 %). During snow mold outbreak seed dressers contained fludioxonil or prochloraz provided high biological efficacy (65,9–85,5 %) in decreasing of winter wheat death and also were effective against root rot. As a result of diseases severity decrease the saved yield has reached 1,55 ton per hectare.

Рresents the results of studies of the influence of organic fertilizers and liming on the density and porosity of sodpodzolic light loamy soils subject to erosion degradation. The positive effect of organic fertilizers on these indicators was established. A strong correlation (r = 0.78) between soil density and humus content was found. There are also strong relationships between crop yields and soil density. The correlation coefficients were 0,93 for winter wheat, 0,75 for oats and 0,92 for spring rape.

The article presents the results of studies on the effect of macro-, micro-fertilizers, a bacterial preparation and plant growth regulator on the dynamics of linear growth and dry matter accumulation by millet plants of various varieties, as well as on grain yield and fertilizer payback.

As a result, it was found that in conditions of soddy-podzolic light loamy soils of northeastern Belarus, the most optimal indicators of linear growth, dry biomass accumulation, and grain yield of millet Galinka and Druzhba 2 varieties were obtained using the mineral nutrition level N90P60K90 and inlaid seeds with a chelated copper form.

The article presents the data of three-year research on the fertilization system of spring wheat varieties Sabina and Tom. The features of the accumulation of nutrients, data on their removal and the utilization rates of elements, depending on the variety and applied fertilizers, are reflected. The high efficiency of the application of liquid nitrogen fertilizer UAN in conjunction with single and multicomponent micronutrient fertilizers, complex liquid fertilizers and growth regulators has been shown. The features of plant nutrition during seed inoculation with a biological product are considered.The article presents the data of three-year research on the fertilization system of spring wheat varieties Sabina and Tom.

The article presents the results of field studies with narrow-leaved lupine varieties Pershatzvet and Yan to study the effect of macro-, micronutrient fertilizers, plant growth regulators and bacterial fertilizers on the yield and quality of seeds. It was found that for narrow lupine, the best option is to use different forms of Co, Cu and Mn against the background of N30P30K90 + Phytostimophos + Sapronite + Epin, since the yield of digestible protein is more than 7 с/ha, the security is 1 unit digestible protein – more than 220 g. Moreover, the protein has a high biological value and the grain meets the FAO / WHO standards in the content of critical and essential amino acids.

In the article the research results on evaluation the influence of mineral fertilizers and plant protection products on grain crops yield formation are presented and also the forecast of their volumes application in connection with the planned yield and total grain yield increase.

The article considers the issue of improving an element of potato cultivation technology use of the Viriy, KS insecticide. The biological and economic effectiveness of the Viriy, KS insecticide on potatoes against the potato Colorado potato beetle in the north-east of Belarus is evaluated.

The article presents the results of studies on the effect of macro-, micro-fertilizers, a bacterial preparation and plant growth regulator on the yield of millet grain, as well as the economic efficiency of its cultivation.

As a result, it was found that in the conditions of sodpodzolic light loamy soils of northeastern Belarus, the most optimal agro-economic indicators of millet of the Galinka and Druzhba 2 varieties were obtained using the mineral nutrition level N90P60K90 and inlaid seeds with a chelated copper form.

The article presents the results of the influence of applying mineral macro-and micro-fertilizers to the soil during the cultivation of oilseed flax. The dependence of their effectiveness on external conditions is established: a year with more uniform precipitation provides stability of crop formation and oil content in oilseeds. Application of mineral fertilizers to the soil at a dose of N60P40K80 allows on average to increase the yield of oilseeds of flax compared to the control by 4,0 c/ha or 31,0 %. The use of various modifications of microfertilizers together with the base dose of macrofertilizers can further increase the yield by 1,1–1,6 c/ha or 8,5–12,4 % on average.

The article presents the description of a new myrobalan plum cultivar Panna (Lama × Gaviota), created in the Institute for Fruit Growing. The tree is strong growth vigor, fast-growing and with spreading habit shape. The productivity in the orchard makes 22,9 tons per hectare. Its fruits are highly resistant to brown rot, the tree possesses hardiness – subfreezing of one-year-old shoot in winters since 2012 has made no more than 3 points. The cultivar is late ripening (the second half of August). Ground color of fruit skin is purple, the flesh is red. Fruits are very large and weight about 62,8 g, their degustation evaluation is 8,6 points, the profitability level is 178 %.

The use of spring fungicides and insecticides on wheat crops increased the yield of varieties by 0,28–0,46 t/ha. The highest crop yields (0,45–0,46 t/ha) were obtained in the treatment of crops with Soligor 425 EC + Fas for IV stage of organogenesis (e. o.) and Capital + Anticolorad at VIII e. o. varieties of hard spring wheat MIP Raiduzhna and Diana. The grown seeds from these variants showed a tendency to increase the germination energy and laboratory similarity (by 1,0–3,0 %).
