This article provides an analysis of the state of the gardening industry, its problems and ways to solve them. The implementation of the State programs for the development of the horticultural industry allowed to increase the production of fruit and berry products in the country, however, despite the work done, the level of self-sufficiency of the republic with domestic fruits and berries remains low, which leads to the need for annual import of horticultural products from abroad. Thus, 250–500 thousand tons of fruit and berry products growing in the country are annually imported for the needs of the republic.The main limiting factor in the development of the industry is the low level of mechanization of technological processes and the lack of mass production of domestic competitive machines for the cultivation of intensive-type orchards, adapted to the agricultural conditions of Belarus. To solve this problem, RUE “SPC NAS of Belarus for Agricultural Mechanization” has developed a number of machines for mechanizing labor-intensive processes of cultivation of perennial plantations, equipping specialized agricultural enterprises of the republic with which will increase the degree of mechanization of processes in fruit growing to 70–80 %, and will provide an economic effect in amount of 43,2 million rubles, and the import substitution effect – 9,6 million euros.

The article presents an analysis of the influence of weather conditions on the formation of a corn crop according to a twelve-year study of the early FAO 200 hybrid in the central part of Belarus. A strong effect of daily average temperatures on the duration of the pre-emergence period has been established. Warm weather during the growing season of corn accelerates the onset of the flowering phase of ears, promotes good growth of plants in height, increasing the yield of grain and reducing its moisture. Precipitation, on the contrary, has a stronger effect on the growth of green mass and a weak effect on the yield of dry matter and grain.

The article presents the results of studies on the productivity and qualitative composition of seeds of various species and varieties of legumes in the northern region of the Republic of Belarus. It was established that the maximum yield of seeds was formed by the varieties of peas Yubileiny and Multik, whose yield was 45,6 and 42,3 c/ha. The advantage both in the content of raw and digestible protein, is the lupine of the narrow-leaved variety Zhodinsky, where their amount in one kilogram was 350,0 and 301,0 g, as well as Streletsky fodder beans, in one kilogram of which 247,7 g crude protein and 215,49 g digestible.

The article presents the results of studies on the effectiveness of cultivation of high oleic sunflower, conducted on Luvisol loamy sand soil.

Maximum productivity of potato plants and tubers multiplication factor in the nursery first tuber generation in greenhouses for growing potatoes prepared in a mixture of peat + turf ground + vermugumus. The most optimum planting density of 25 plants/м².

The article discusses the economic and agronomic efficiency of the use of fertilizers, seed inoculation and top dressing with tank mixtures of UAN with micronutrient fertilizers, complex liquid fertilizers and growth regulators for spring wheat varieties Sabina and Tom. According to the data of three-year studies, it was found that a more effective fertilization system for two varieties was the use of nitrogen fertilizing UAN together with the growth regulator Fitovital, which, against the background of N₆₅P₆₀K₉₀ + N₂₅UAN, increased the yield in the Sabina variety from 4,8 to 5,4 t/ha and in the Tom – from 4,3 to 4,9 t/ha.

The article presents the results of three summer studies on the growth, development and yield of sugar beet at different doses of fertilizers during irrigation in the Eastern part of the Mogilev region of Belarus. Two doses of N₁₂₀P₉₀K₁₈₀ fertilizers were used in the experiment and N₁₅₀P₁₁₀K₃₀₀. For experiments, a zoned variety of sugar beet single-seeded Belpol was used. The soil is a sod-podzolic light loam, developing on a light pulverized loess-like loam, underlain by a morainic loam from a depth of about 1 m. Тhe monitoring was conducted to maintain soil moisture within the boundaries of 60 % HB, 70 % HB, 80 % HB. As a result of research conducted in 2017–2019 it was found that the greatest impact on the yield was the lower limit of regulation of 70 % HB.

The results of an agrochemical composition of the discharge channels sediment of fish ponds washed from different types of underlying soils are presents in the article. The main agrochemical indicators are determined, the availability of the discharge channels sediment with nutrients for plants is estimated, their agrochemical properties are compared by the gradation existing for soils.

It was established that for all agrochemical indicators, discharge channels sediment washed out of peat and peat-clay ponds was characterized positively and can be good material for use as fertilizer for agricultural crops. Less suitable were sediments from sand ponds.

The results of studying the effectiveness of the liquid humic fertilizer Biovermtechno application in winter wheat cultivation technologies are presented. It is found in demonstration, trials that three-fold application of fertilizer: seed treatment → crops treatment at tillering stage (before leaving for winter) → at flag leaf stage provides with the formation of high grain yield and quality of products suitable for food purposes use.

The biological efficiency of a new three-component herbicide Fixit, SC in winter wheat crops against annual dicotyledonous and annual weeds including the ones resistant to preparations of 2,4-D, 2M-4X group, dicamba by autumn application is shown. High farming and economic efficiency of the studied herbicide has been resulted.

It is shown that the application of herbicide KAMARO, SE (florasulam, 6,25 g/l + 2,4-D ethyl-hexyl ether, 452,4 g/l) ADAMA Registrations B. V. the Netherlands Co. production in winter wheat crops by autumn and spring application in Belarus provides with rather high biological efficiency against the dominant annual weeds (80–100 % kill). However, this herbicide is not effective against annual grass weeds, that is why the additional weeding with herbicides effective against these weeds or the use of studied herbicides in tank mixtures with graminicides is necessary.

In the article the research results of specific composition and weed plants distribution in spring wheat crops under conditions of the Republic of Belarus for the period of 2015– 2016 are presented. The dominant species are revealed and weed plants frequency of occurrence by agro climatic zones of the crop cultivation are determined.

The peat soils of different transformation stages sorb pendimetalin, metribuzine, imazamox and c-metolachlor 1,2–11,1 times higher compared to mineral sandy loamy. Peat soil depositing capacity for metribuzin was 80–95 %, pendimethlin – 90–98 %, imazamox – 10–90 % and c-metolachlor – 69–94 % depending on organic matter content.

The article presents the results of many years of work by scientists Institute vegetable growing to find ways to adapt vegetable growing to the changing climatic conditions of the Republic of Belarus.
