In today's difficult conditions, there is an acute shortage and rising prices for various types of energy resources, including mineral fertilizers. The variability of climatic and weather conditions and the high cost of mineral fertilizers leads to the search for alternative approaches to optimize existing and develop new technological methods of cultivation. This article evaluates and identifies the main aspects of optimizing the corn fertilization system through the use of modern biofertilizer Grandfix in combination with mineral fertilizers in full and with a reduction in their rate by 30%. The urgency and production necessity of such technological solutions and the search for optimal options for maximizing the yield potential of modern maize hybrids are determined given the importance of this crop for the formation of Ukraine's export potential. The efficiency of application of soil biofertilizer Graunfix produced by BTU-Center, which is recommended for pre-sowing cultivation, in combination with full and reduced rate of mineral fertilizers at different rates of seed sowing. It was established that with the application of soil biofertilizer Groundfix at the rate of 6 l / ha, the increase in yield was, respectively, 5.4-7.1%, or 0.82-0.97 t / ha. The maximum yield in the experiment was 18.31 t / ha and was recorded in the hybrid P8834 on the variant with a seeding rate of 75 thousand / ha.

Among cereals in the agro-industrial production of barley is a leading place in the structure of sown areas, it is second only to wheat. However, when conducting a comparative analysis of the yield of barley in Ukraine and other world producers, it should be noted that the average yield of its grain in our country is 2.5 t / ha, while in France it reaches 6.09 t / ha, Great Britain - 5 , 67, Germany - 5.69 t / ha [2]. Therefore, there is a need to find ways to increase the productivity of spring barley in specific conditions of its cultivation. One of the main ways to increase crop productivity is the stable growth and development of spring barley. Development is the formation of specialized organs and parts of aplant to perform its main biological function: the preservation of its species. Of particular importance in the cultivation of cereals are the processes of growth and development that underlie the formation of grains. One of the most important problems of plant growth and development in the technology of growing crops, in particular spring barley, is its growth processes. A characteristic indicator of growth processes, which affects the formation of crop yields, is its height. During our research, a lot of attention was paid to the development of culture in the right-bank forest-steppe of Ukraine.As a result, it was found that the height of plants increased from the germination phase to full maturity, due to increased plant biomass and depended on varietal characteristics and technological methods of cultivation and hydrothermal regime of years of research. Higher plant height in the phase of full maturity was observed in the variety Aizhan - 55 cm, and in the variety Aristei - 50 cm. It was found that depending on the factors studied, the height of spring barley plants in the tillering phase did not change significantly, but starting from the exit phase into the tube, the difference in height was significant. The application of mineral fertilizers provided an increase in the height of spring barley plants.","PeriodicalId":7511,"journal":{"name":"Agriculture and Forestry","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88175352","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}

In modern agricultural production, the variety is the biological foundation on which all elements of cultivation technology are based. If you choose the right variety, it will enhance the effect of other factors. Conversely, if the manufacturer makes a mistake with the chosen variety, it will weaken the effect of all other factors. In agricultural production, it is difficult to predict the outcome, because the existing approaches to soybean cultivation are 70% dependent on soil and climatic conditions. To solve this problem, you need to carefully select adaptive varieties of soybeans. In Ukraine, a fairly large range of soybeans of different maturity groups. In conditions of intensive agriculture with extreme weather conditions, it is important to grow several varieties of different maturity groups on farms. The article highlights the results of the analysis of the State Register of plant varieties suitable for distribution in Ukraine, as well as analysis of research by other scientists on the basis of which we chose two adaptive varieties of different maturity groups with genetic potential of 4-5 t / ha Ukrainian and foreign selection: Ukrainian ( early-ripening variety Nugget) and Canadian selection (early-ripening variety Amadeus). These varieties are adapted for growing in the Forest-Steppe zone, have high resistance to lodging and shedding. Resistant to soil moisture deficiency, high temperatures and drought-resistant in summer, which is relevant in climate change. The height of attachment of the lower beans in the nuggets Nuggets and Amadeus 13 cm, which determines its suitability for full mechanized cultivation from sowing to harvesting.
