The analysis results of the effect of powdery mildew and Septoria leaf and ear disease on productivity elements, physical and chemical parameters of winter triticale cultivars and appreciable varieties which are grown using common and intensive cultivation technologies are presented in the article. The complex of the studied diseases had the greatest effect on seed yield and biochemical composition. Increase in the intensification level of winter triticale cultivation technology reduced significantly the degree of association between those parameters.

Sorghum crops in the northern region of the Republic of Belarus form the yield of green mass in the range of 252,7– 530,4 c/ha. The most productive of them is the sorghumsudank hybrid with single-axis use, the minimum yield of the green mass was formed by chumiza. For the collection of raw and digestible protein, sorghum-sudanese hybrid crops had an advantage with single-crop use, where these indicators were 14,3 and 9,7 c/ha and sudanese grass – 9,20 and 6,2 c/ha, respectively. In all the studied sorghum cultures, the provision of a feed unit with digestible protein was in the range of 68–91 g. 

The article reveals the need to switch to a wider use of integrated farming technologies with the application to the vegetative part of plants of easily digestible polyfunctional complexes containing macro and microelements for plant nutrition and having both a fungicidal and growthstimulating effect.  

The analysis of the results of comparative studies of technologies and machines for surface and basic soil treatment is carried out. The advantages of domestic technologies and equipment are shown. 

The article presents the results of research on the effectiveness of micro-fertilizers AmiStim, VR. It was found that in comparison with the standard, the foliar treatment of flax plants increased: plant survival – by 0,4 %, seed yield – by 0,7 c/ha, total fiber yield – by 1,3 c/ha, long – by 0,9 c/ha, fiber quality – by one number. 

Studied influence of leaf fertilizer Terra-sorb Сomplex on elements of structure of a crop winter rape. Leaf fertilizer Terra-sorb Сomplex at entering into a doze of 0,4–0,6 l/hectares in a phase the beginning budding and in a doze of 0,4–0,6 l/hectares in a phase full budding increased in comparison with a control variant quantity of pods on 1 plant on 7–24 pieces, weight of 1000 seeds – on 0,06–0,32 g, weight of seeds from 1 plant – on 1,01–3,29 g, biological productivity oilseeds – by 0,44–0,67 t/hectares. On the average the maximal productivity oilseeds winter rape 4,32 t/hectares is received for three years of researches in the third variant, the increase to the control has made 0,52 t/hectares or 13,7 %. The greatest increase on gathering a crude protein (0,1 t/hec tares), and on gathering fat (0,34 t/hectares) winter rape provided at entering leaf fertilizer Terra-sorb Сomplex into a doze of 0,4 l/hectares in a phase the beginning budding and in a doze of 0,4 l/hectares in a phase full budding. 

The article presents the results of phytotesting of production waste generated as a result of the activities of UPUE «Brest Waste Processing Plant». It has been established that the studied wastes do not have a toxic effect on the growth of oats, barley, wheat, maize, alfalfa, rape and oilseed radish in the early stages of development. A significant stimulating effect of water extract from production waste on the growth of the hypocotyl of seedlings of rape and oilseed radish was noted. 

Efficacy of 18 seed dressers for protection of spring wheat against soil and seed infection, depending on the composition of active ingredients is represented for the period 2010–2021. Efficacy of seed dressers including fludioxonil or prochloraz for protection against Fusarium fungi on seeds has reached 100 %. The most effective seed dressers against Alternaria fungi on seeds are ones including fludioxonil. Regardless of their composition, all analyzed seed dressers provides a high efficacy against Fusarium root rot even in an artificial inoculation with pathogens before sowing. 

The article presents the data of long-term monitoring (2017–2021) of the development of root rot on cereal crops in the conditions of variety testing stations and plots of Belarus. The data represents that disease is common on winter crops (wheat, triticale, rye, barley) and spring crops (wheat, barley, triticale, oats). Among winter crops, barley and wheat crops were more intensively affected during the observation period, and among spring crops wheat as well. During investigation disease severity among winter crops has reached 49,7 % (wheat), 29,7 % (triticale), 22,7 % (rye), 60,5 % (barley), whereas on spring crops 39,8 % (wheat), 26,1 % (barley), 26,7 % (triticale), 19,0 % (oat). 

The article presents the results (2019–2021) of assessing the susceptibility of winter cereal crops varieties to snow mold. It was found that the degree of disease severity depends on the height of snow cover (r = 0,81) and the duration of its occurrence (r = 0,74). Disease severity reached 87,4 % (variety Augustine), winter triticale – 68,6 % (variety Dynamo), winter rye – 47,8 % (variety Zazerskaya 3), winter barley – 42,0 % (variety Isocel).

The results of the influence of the main elements of the technology of cultivation of winter rapeseed in the summerautumn period on overwintering and productivity are presented. It has been established that for the optimal development of winter rapeseed plants and successful overwintering, even in favorable years, the period of summer-autumn vegetation should be 57 days or more. It was revealed that the main factor in the development of winter rapeseed plants, against the background of optimal mineral nutrition, is the sowing time, which provides an increase in yield from 4,0 to 32,5 c/ha or by 12–63 %. It is shown that the highest yield of this crop (44,2 q/ha) was ensured by sowing in the conditions of the central zone of Belarus on August 20, with the duration of the autumn vegetation of 64–90 days. It has been shown that due to the temperature factor, even the optimal sowing time for this crop should be "insured" by the use of growth regulators, the overwintering of which varied from 52,8–55,6 % (control) to 81,5–89,2 % (in variants with the use of growth regulators), against the background of mineral nutrition, seeding rates and sowing dates. 

The article presents the results of many years of research and testing of innovative technologies of integrated farming in the cultivation of potatoes, shows the advantages of soil preparation methods for "green fertilizer" – the precursor of potatoes, basic soil treatment and cultivation, soil mulching, preparation of seed beds, rows and inter-row treatments. The possibilities of using “Shkval” spray systems for treatment of seed potato tubers and the use of agrochemicals by spraying have been determined.
