Establishment of the effect of seed inoculation with bacterial preparations and foliar dressing with micronutrient fertilization on the symbiotic productivity of chickpea varieties in the Right-Bank ForestSteppe. Methods. During the research, the following methods were used: field; statistical. Results. The results of the research on the effect of bacterial preparations as well as foliar microfertilizer application at different stages of organogenesis on nodules formation, their mass and nitrifying ability of chickpea Pegasus and Triumph varieties are presented. As a result of foliar fertilization, the mass of nodules in chickpea varieties gradually increased, which was caused by the process of photosynthesis intensification and, accordingly, an increase in the amount of assimilation elements in the formed nodules. It has been established that high indicators of symbiotic productivity in chickpea plants were observed when seeds were inoculated with the bacterial preparation Rizoline + Rizoseiv in combination with two foliar feeding with microfertilizer Urozhay Bobovi. Observation of the dynamics of accumulation of the number and weight of nodules showed that the maximum indicators during the growing season of chickpea were recorded in the phase of complete flowering. During the formation of the indicators of the number and mass of nodules, the varietal differences of chickpea were established. Maximum rate of knobs formation, their mass and nitrogenase activity (in the variety Pegasus – 41.3 pcs/plant, 0.92 g/plant, 4573 nmol ethylene/plant, in the variety Triumph – 37.9 pcs/plant, 0.72 g/plant, 4301 nmol ethylene/plant) were observed in the variant with the presowing treatment of seeds with the bacterial preparation Rizoline + Rizoseiv with two foliar feedings with microfertilizer Urozhai Bobovi. Conclusions. For the maximum realization of the genetic potential of chickpea Pegasus and Triumph varieties, the technology of its cultivation should envisage sowing with seeds, treated with biological preparations in combination with bioconstructor and carrying out two top dressing with microfertilizer application to plants in the phase of intensive growth and budding.","PeriodicalId":384529,"journal":{"name":"Feeds and Feed Production","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1970-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132071408","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}

To substantiate the scientific and theoretical principles of using total mixed ration in dairy farming. To identify priorities for the total mixed ration effectiveness in feeding cows. Methods. Observation, comparison, analysis and synthesis, systems analysis. Results. The essence of the total mixed ration is considered and its key role in the formation of cow productivity is determined. It is established that only a comprehensive approach to the ration management at all stages of feeding cows can provide energy and all necessary components of animal diet, which will ensure maximum feeding efficiency. Constant monitoring of the ration quality is necessary to choose the most profitable alternative. The reasons for the milk quality decline in agricultural formations of Vinnytsia region have been scientifically substantiated and the relationship between the dry matter content in the diet of cows and their productivity has been studied. It is proved as well, that the successful management of cow feeding consists in compiling a diet with the maximum possible predicted consumption of dry matter by animals at the optimal concentration of energy carriers, protein, minerals and vitamins. Directions for the complete mixed diet management are outlined. The methodical approach to determining the daily requirement of a cow in pure lactation energy and dry matter to maintain vital functions and ensure high productivity is highlighted. Conclusions. In order to achieve maximum productivity of cows, it is necessary to follow the good practice of feeding TMR: regular control of feed stocks and their distribution in the appropriate group of animals; permanent control over the quality and safety of rations: regular updating the ration depending on the productivity of cows, the percentage of milk fat and milk protein, current body weight and body condition, changes in feed moisture or feed ingredients and feed pricing policy (based on analysis of the quality data monitoring and composition of the fed feed).","PeriodicalId":384529,"journal":{"name":"Feeds and Feed Production","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1970-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123863978","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}

To study the influence of sowing terms on soybean varieties interphase and vegetation period duration in the Western Forest-Steppe. Methods. Field (visual and phenological observations of the growth and development of soybean plants); statistical (statistical processing of research results). Results. The research was conducted at the Khmelnytskyi research station of the Institute of Feed Research and Agriculture of Podillia of NAAS during 2016-2020 on the podzolic medium loam black soils. Weather conditions in the years of research at the time of soybean sowing were different, which allowed studying the impact of the studied factor on the “sowing-seedlings” period duration. Summarizing the results of observations, it was found, that on average over the 5 years of research, it made up 17-20 days for early, 11-14 and 10-13 days – for optimal and late sowing terms, respectively. It should be noted that high average daily air temperatures, high rainfall with uneven distribution and significant deficit in some phases of soybean development had a considerable impact on the duration of the growing season, plants growth and development, formation of their individual productivity and seed yield of all the studied soybean varieties. According to the results of the five-year research, it was established, that the longest duration of all interphase periods was observed at the early sowing terms, the shortest – at the optimal and late ones. In general, the period of “seedlings-ripening” was shorter at the optimal sowing period by 3-4 days, at the late – by 1-2 days compared to the early sowing terms. Among the soybean varieties of domestic selection studied in conditions of the Western Forest-Steppe, the shortest “seedling-ripening” period was observed in the KiVin soybean variety (106-109 days), the longest (114-118 days) – in the Triada one. In other soybean varieties it ranged from 107 to 112 days depending on the time of sowing. Conclusions. The most effective for the conditions of the Western Forest-Steppe are optimal and late sowing terms at which seeds are sown in a wet seed bed, precipitation falls in the critical for the growth and development of soybean plants period, and duration of the interphase and vegetation periods are generally optimized.","PeriodicalId":384529,"journal":{"name":"Feeds and Feed Production","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1970-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114798920","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}
