At the same time, according to the results of scientific recommendations, the optimal area for sowing corn for grain and silage in Ukraine should be within 3 million hectares. Until now, the question of the optimal location of corn crops for grain in Ukraine is controversial. It is established that currently the placement of grain corn in the natural and economic zones of Ukraine does not fully ensure the effective use of bioclimatic and economic potential to increase grain production. And this, in turn, necessitates further improvement of the location of this culture in some regions of the country. Since modern crop rotations include a very limited set of crops: winter wheat, corn, sunflower, partly winter oilseed rape and soybeans, it is difficult to choose the optimal or even acceptable precursors for corn. Maize is often grown after winter wheat, but this precursor is lacking because it is used for sowing sunflower, winter oilseed rape and soybeans. If re-cultivation of other crops is not allowed, then corn can withstand such crops. Therefore, part of the corn crop is re-sown after corn for two or three or even more years. In repeated crops, the rate of application of mineral fertilizers can increase by 20-30%. Prolonged use of such mineral fertilizers can cause contamination of soils and products with heavy metals, nitrates and other toxicants, acidify or alkalize the soil reaction. Also, monoculture cultivation of corn causes deterioration of the phytosanitary condition of the agroecosystem, in particular the spread of pests, diseases, specific weed species resistant to herbicides. A problem that has spread in recent years is the intensive development of the meadow butterfly, which causes the complete destruction of corn seedlings. This requires intensifying the protection of corn from pests that also affect the ecological state of the agroecosystem.","PeriodicalId":7511,"journal":{"name":"Agriculture and Forestry","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86980870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(12,2%). Common bean varieties with high attachment of the lower beans on the plant were identified. Among the totality of the original material submitted varieties were: UD0302930 (Ukraine) - 16.7 cm, UD0302957 (Ukraine) - 16.5 cm, UD0301502 (Ukraine) - 16.0 cm, Local 2 (Ukraine) - 15.6 cm.

Consequently, UD0300411 (Romania) with 45.7 and UD0301736 with 44.2 seeds per plant were noted to have significantly exceeded the standard in this indicator. At level with the standard number of seeds per plant was found in samples UD0301043 (Turkey), Local 1 (Ukraine) - 38.9 pcs. The quantitative expression of the trait 1000 grains weight is a confirmation of the previously reported material, that in order to form the maximum expression of the trait in grain legume crops, including common bean, parental forms are included in hybridization for the expression of yield structure elements slightly above the average in the whole sample. That is, the varieties that stood out both in the number of beans per plant and the number of seeds per plant were inferior to other samples, in which the number of beans and the number of seeds per plant were lower.

It is determined by the potential stock of weed seeds in the soil and its long-term viability. The presence of large amounts of weed seeds in the soil creates significant problems for growing chickpeas. Therefore, the assessment of weed efficiency of any farming system or its component should be based on quantitative changes in potential soil weeds. The interaction between crops and weeds in chickpea crops has its own characteristics, because in the first period of the growing season they grow very slowly and have little effect on the conditions of weed growth, so there is a rapid growth of segetal vegetation. In the technology of growing chickpeas in the plant protection system traditionally use the chemical method. However, even with high efficiency, this method does not always give the desired results, there is a violation of ecological balance in agrocenoses, reduction of species biodiversity, contamination of soil and plants with chemicals, reducing product quality. Observance of agrotechnologies, constant phytosanitary monitoring, effective diagnostics and forecast of development and spread of harmful organisms in chickpea crops are important in ensuring proper phytosanitary condition. Regulation of weeds and their harmful effects in agrophytocenoses of chickpea drawing them to an economically harmless level is a significant condition in the technology of its cultivation. The main control of weeds is done at the beginning of the growing season, because at this time chickpeas grow very slowly, and are in the rosette phase for a long time, and therefore cannot withstand competition from weeds. To increase the yield of chickpea seeds, an important place in the technology of cultivation belongs to the use of herbicides and biological products.

It was established that in the agrophytocenosis of soybean, a mixed type of infestation was formed, in which dicotyledonous young weeds predominated. Weed control efficiency was 75.5% 60 days after application of Frontier Optima. Spraying crops with the insurance herbicide Korum (1.5 l / ha + surfactant Metholate 1.0 l / ha) reduced the number of weeds in soybean crops by 89.5%. Consistent application of the soil herbicide Frontier Optima (1.0 l/ha) and the insurance herbicide Corum (1.5 l/ha + surfactant Metolate 1.0 l/ha) made it possible to destroy up to 98.9% of weeds compared to the control variant, where there was a natural background of clogging. The combination of the use of the above herbicides with the concentrated molybdenum microfertilizer Quantum-Chelate Molybdenum provided the best conditions for the growth and development of soybean plants.

The study and widespread use of the products of the California red worm is an extremely important task in the cultivation of biologically high-quality agricultural products, as it is possible to obtain high yields of environmentally friendly products without excessive use of synthetic fertilizers.

The increase in the number of vermiculture of the California worm in the heated room was 42.5%, and in the unheated room - 34.0%. The weight of biohumus produced by California worms after 180 days of development in the heated room was 1647 g per container, which was 35.8% more than in the version of the development of worms in the unheated room.
