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 lead to the search for alternative approaches to the optimization of existing and the development of new technological methods of cultivation. This article presents the results of studies on the impact of biological preparations, namely the inoculants Bioinoculant BTU, Rizoline + Rizosev, Anderiz and biological fertilizers for foliar feeding Biocomplex BTU, Gumifrend and Helprost soybean on the formation of the leaf surface area and productivity of soybeans. Conducting field research involved studying the impact of pre-sowing seed treatment, foliar fertilization and their combination in order to determine the most effective model of their use. On the basis of the conducted observations and records, it was established that in the conditions of the right-bank forest-steppe on gray forest soils, the investigated preparations of biological origin had a direct effect on both the dynamics of the leaf surface area and the formation of productivity.

In field conditions, the chemical effect of Elytrigia repens L. on the growth of all agricultural crops is characterized as inhibitory. Therefore, the purpose of the article was to establish in laboratory conditions the phytotoxicity of water extracts from the rhizomes of Elytrigia repens L. at various concentrations on the germination of wheat seeds and further development of seedlings. In the course of research, we established that the presence of allelopathically active substances of creeping wheat inhibits the energy of wheat seed germination in all experimental variants. The water extract in a ratio of 1 to 1000 had a stimulating effect on seed germination and further growth of wheat seedlings compared to the control option, in which its seeds were germinated in distilled water. An increase in the concentration of water extracts of creeping wheatgrass (1:100; 1:50; 1:20 and 1:10) directly proportionally led to a significant inhibition of the growth of the germinal root of wheat. The lag of indicators in length ranged from 0.34 cm (1:100) to 1.32 cm (1:10) on the fourth day of accounting. Further measurements of both the length of the germinal root and the total length of the root system of wheat confirmed the prolongation of the negative impact of wheatgrass emissions. The stem length of wheat seedlings also depended on the concentration of allelochemical substances of Elytrigia repens L. in Petri dishes: it decreased with increasing concentration. According to the above options, during the accounting on the 7th day, the decrease in the indicator was from 44.4% (1:100) to 95.9% (1:10) in relation to the control option. That is, the allelopathically active water-soluble substances of Elytrigia repens L. can have a stimulating or inhibiting effect on the germination process of wheat seeds, depending on their concentration level.","PeriodicalId":7511,"journal":{"name":"Agriculture and Forestry","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82132555","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}

The weeding structure of the agrocenosis of winter rape is presented as follows: on average there were 53 plants/m2, among which the presence of monocots was 14 plants/m2 and dicots 39 plants/m2. Therefore, it was established that the type of weediness is mixed, and the degree is medium. The drugs studied in the experiment did not inhibit winter rape plants and liquefaction of crop density was not observed. Treatment of rapeseed crops with Noostim was important for regulating the development of cultivated plants, reducing the risks of stress from pesticide load, ensuring control of the most common diseases and contributing to increased yields. Typhoon herbicide treatment (2.0 l / ha) reduced weeds by 79% compared to controls. Only cereal weeds remained after the application of the insurance herbicide Slash (1.0 l / ha). Higher height of winter rape plants and better branching ensured an increase in yield with consistent application of herbicides. Statistical evaluation of the obtained data confirms that the introduction of herbicides reduced the number and harmfulness of weeds, which significantly affected the growth of yield.

The optimal tank mixtures and technological combinations of new soil and insurance herbicides have been determined, which provide a high level of technical efficiency on a wide species spectrum of weeds that clog corn crops. In particular, for farm conditions, the complex nature of the formation of the type of weediness, which changes during the growing season of the crop, was noted. The results of assessments of the dynamics of weed vegetation indicate a gradual increase in cenotic tension due to the gradual transition of dominant species of weeds, such as Chenopodium album L., Amaranthus retroflexus L., Echinochloa crus-galli L., Elytrigia repens (L.) Gould , Sonchus arvensis L, Cirsium arvense L., Convolvulus arvensis L. in the middle tier of sowing with a simultaneous increase in the frequency of their determination by 1.1-1.3 times.

It is one of the most productive cereals of universal purpose, which is grown for food, feed and technical purposes. In the countries of the world about 20% of corn grain is used for food needs, 15-20% for technical needs, 60 - 65% for fodder for farm animals. In our country, corn is the most important fodder crop. At its expense, livestock is provided with concentrated feed, silage and green mass. The most valuable feed is corn grain, which contains 9-12% protein, 65-70% carbohydrates, 4-8% oil, 1.5% minerals. 100 kg of it contains 134 feeds, units, up to 8 kg of digestible protein. In the current conditions of agricultural production, biological fertilizers and drugs with different mechanisms of action on plants are in increasing demand among agricultural producers. Particular attention is paid to biological products that promote the active settlement of root and root zone mycorrhizal fungi and saprophytic rhizosphere bacteria, one of which is Melanoriz and complex fertilizers based on potassium humate type Gumifrend, which are created with additional content of beneficial microorganisms and their products. These biological preparations ensure the development of soil biota, increase soil fertility, while activating its suppression against phytopathogens, increase crop yields, including corn. The research was conducted with the use of modern promising biological products, manufactured by BTU Center, which were used for pre-sowing seed treatment and application to foliar fertilization.

It was investigated that the yield level of winter wheat within the Volyn region fluctuates almost one and a half times, which is caused by the heterogeneity of the soil and climatic conditions of the region. The general yield levels of winter wheat were established: it is the largest for cluster 1 (Forest-steppe zone), the smallest - for cluster 2 (Polyssia) and has an intermediate value for cluster 2 (transition zone). The approach of the specific yield of cluster 3 to the zero level emphasizes the stable transitional nature of the corresponding space within the Volyn region. After 2000, the rate of yield growth within Polissia began to rapidly decrease compared to the rate of growth of winter wheat yield in the Forest Steppe, so the share in the total yield in the region became smaller in Polissia. Variability in time of winter wheat yield is the smallest in the south and center of the region, and the largest in the north, east and west. The presence of asymmetry indicates the heterogeneity of winter wheat yield conditions and regimes during the research period and the possibility of establishing qualitatively homogeneous time intervals, i.e., the periodization of the studied time according to winter wheat yield indicators. The asymmetry of the distribution is also accompanied by its two peaks (there is a strong positive correlation between asymmetry and kurtosis r = 0.95, p < 0.001). Such results emphasize the presence of heterogeneous periods in the temporal yield of winter wheat during the research period.\u0000Periodization by types of winter wheat yield dynamics established that in periods 1 and 2 it was synchronous in all spatial clusters, and in the third period there was a differentiation of yield growth rates.

The expediency of cultivation is proved and the importance and features of this crop as a food and fodder crop are indicated. The role of weeds and their impact on winter rye crops is also outlined. Winter rye belongs to high-yielding cereals. Advanced farms harvest 40-50 c/ha and more of grain. The experience of these farms is highlighted in the analysis of scientific literature sources, which indicates the presence of reserves for increasing the yield of rye in Ukraine. It is grown mainly for grain, as well as for green fodder (often in mixtures with winter vetch, winter rape). Rye bread has high nutritional and taste qualities due to its high content of proteins, vitamins (A, B, E) and high energy value. Rye grain is of great importance as a concentrated feed for farm animals. Rye flour is used for feeding pigs, and bran - for cattle. In a mixture with winter vetch and winter rape, rye in spring gives the earliest green fodder for animals. It is noted that weeds are most often present in crops of field crops from the groups of rhizome perennial weeds and root-sprouting weeds. Quite often there are pink thistle (Crisium arvense L.), field bindweed (Convolulus arvensis L.), creeping wheatgrass (Elytriga repens L.), horsetail (Equisetum arvense L.), creeping bitterweed (Acroptilon repens L.) and others. Among the most aggressive species are representatives of winter and biennial dicotyledonous wintering weeds. The most commonly found in winter rye crops are the following representatives: wild poppy (Papaver rhoeas L.), wild violet (Viola arvensis.), odorless chamomile (Matricaria perforate), wild poppy (Papaver rhoeas L.), common bindweed (Capsella bursa-pastoris), Sophia's curlyleaf (Descurainia sophia L. ), clinging feverfew (Galium aparine.), field axes (Consolida regalis S.), Sophia's curlyleaf (Descurainia sophia L.), medium starwort (Stellaria media), white pupal (Melandrium album), Sophia's descurainia (Descurainia Sophia), field thalassa (Thlaspi arvense). It was found that the correct selection of the predecessor for the cereal crop of winter rye will be able to satisfy high grain productivity, which will allow maintaining the agrophytocenosis in proper condition in relation to the negative impact of weed infestation and will help to reduce the overall number and species composition of segetal vegetation in winter rye crops.","PeriodicalId":7511,"journal":{"name":"Agriculture and Forestry","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89149287","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}
