In the article we show the history of opening of selenium, its distribution in the nature, the value of this microcell in life of plants.
We also show the experience of russian and foreign scientists on studying of the influence of selenic fertilizers on a crop and quality of crops
In this article, we review the influence of different pro-duction technologies for nitrogen, phosphorus and potassium in the soil under alfalfa, and the impact of culture on the accumulation of nitrogen in the soil
In adverse dry weather conditions the yield of traditional crops is sharply reduced, particularly of maize, therefore it is required a drought-resistant crop with high forage characteristics. This crop is the grain sorghum. The presence of non-starch polysaccharides in sorghum grain creates the preconditions for the inclusion of enzyme preparations in the combined feed for broiler chickens. The aim of the study was to provide high productivity of the broilers fed the combined feed, containing up to 30% of grain sorghum with the additional use of the enzyme preparation "CelloLux -F". Positive results are achieved both in productivity and digestibility of the main nutrients in the combined feed with the enzyme. It is recommended to include the enzyme into combined feed for broiler chickens at the amount of 100g/t of feed. Application of enzymatic agent "CelloLux -F" as a component of combined feeds for broiler chicks favors live weight gain, feed conversion efficiency and safety of young birds. It is recommended to include the enzyme into combined feed for broiler chickens at the amount of 100g/t of feed
Zoo engineering expediency of triticale utilization as part of combined fodder for pigs in their growing and finishing is studied. Triticale grain may be used as part of combined fodder for young pigs up to 50 %
Obtaining a high intensity of growth calf in dairy period contributes to the feeding of the high daily doses of milk (8-10 kg) and schooling to early eating plant forage, which increases their live weight by 11.4-15,1%, growth energy - 13,2-16.5% and reduces the cost of feed per 1 kg of body weight gain of 4.6-8,6%
The economic-biological features influencing productivity of green weight and fodder value of grain are defined on the basis of researches of features of new grades of Turkestan millet
This article has explored different ways of watering annual apple seedlings in pots. The greatest phytomass was obtained with pellets of Aqualife supersorbents in the version of 10gr. dosage
In this article, we have considered the possibility and the availability of cold plasma technologies application in different branches of industry. We have described the investigations of cold plasma treated water in potato growing technology which will conduct in PetrSU at Agricultural faculty. The basic parameters of the device for water treatment with cold plasma are described. The results of the experimental investigations about cold plasma treated water influence on potato growth and productivity are presented
The article presents the analysis of climatic data concerning Michurinsk district of Tambov region, which is necessary for modeling of stressors, on the stage of their maximum values, which will help to increase the precision of selection procedure in fruit crop forms. On the base of the investigation, differences in initial fruit crop forms by their adaptivity and productivity under stressor effect on the level of their maximum values were revealed
In the article, the results of studying of laws of inheritance of quantitative signs of winter barley are presented
