A comprehensive assessment of the state of the agro-industrial complex of Russia is given and its role in ensuring national food security is defined. The main directions of ensuring state food sovereignty in the conditions of global challenges are substantiated. The scheme of interaction between the world and national agroindustrial complex is presented. The main tasks of development of the agrarian sector of the economy are formulated: the growth of production per capita; ensuring physical and economic accessibility of food in the required quality and assortment. It was revealed that the volume of production of basic food products in Russia in 2015 did not reach the indicators of 1990, and the consumption of basic food products in Russia by individual items is significantly lower than the recommended rate. Deficiency of a diet of the population of the country on vegetables and melons, fruit, milk and dairy products is established. The expediency of reforming the agrarian sphere of the Russian economy is proved, including its accelerated adaptation to global challenges. They include geopolitical tensions, deterioration in the external economic environment and a reduction in external demand, mutual economic sanctions, fluctuations in inflation indices, and a reduction in consumer demand. It was concluded that for the increase in the efficiency of the functioning of the agroindustrial complex and the strengthening of national food security, technical and technological modernization of production, improvement of the mechanisms of state support, active development of the innovation environment are needed
Based on obtained experimental investigations it is shown that microelements included into winter wheat fertilization system positively influence plants mineral nutrition, quantity and quality of the crop
The results of the long-term investigation of the stabilization of the humus content in the soil by the agricultural methods are contemplated and summarized in the article
The article presents data on the morphological and biological characteristics of Agrodeum varieties, the results of the competitive test were shown, as well as the adaptability of varieties to different conditions of cultivation and the main indicators of quality of new grain varieties
In the article, the results of the analysis of agrometeorological factors of formation of a crop of long-term cultures are resulted. The regressive correlation analysis of the given conditions and growth of bean and cereal grasses has allowed to establish high correlation dependence between change of a crop and number of days of growth for cereal herbage. It is noticed, that change of the efficiency of the bean is less closely connected with time of formation of herbage, than cereals. Also, for fertilized bean and cereal the correlation factor between the crop and the term of growth of the grass is higher, than for not fertilized ones. The backward correlation dependence between the changes of the maintenance of a raw protein, ashes in a forage from the first hay crop of cereal herbage and, accordingly, the sum of temperatures more 5°С is established
The article shows prospects of the use of growth regulators on the nature of humic culture of rice in the first place due to the low field germination of seeds, rice crops lodging. Effect of humate on the growth, development and photosynthetic activity of plants, as well as the consumption of nitrogen, phosphorus and potassium results in increased grain yield of rice. Depending on the type of humate yield increased by 5,0-6,4 с/ha. Seed treatment caused a change humates biochemical and technological indicators of the quality of grain. Beans with these options contain more than in the control of protein per 0,13-0,44 % starch - 0,36-1,2 %, decreased membranous grain by 0,2 % and 1 % fracture, raised on vitreousness 1,46-2,0% and the yield of cereals on 1,06-2,0 %
One of the methods of increasing the productivity of alfalfa is the use of growth regulators, and the use of polymeric compositions of growth regulators, binders with synthesized growth regulators of sim-triazine series is promising with the possibility of creating environmentally friendly technologies for growing alfalfa. Studies have shown that the application of the test on alfalfa growth regulators has a positive effect on growth, physiological and morphogenetic processes, plant resistance to adverse environmental conditions. Intensity impact on plant growth regulators depends on the type of plant growth regulators, concentration and method of application. Processing alfalfa seed growth regulators on germination increases energy 3,0-14,0 % germination on 8,0-17,0 %. Processing plant growth regulators to enhance the growth of plants in height (on the 7th day – 2,6-11,9 % , on the 14th 41,9-48,0 %) , the growth of aboveground biomass , expands on the number of productive branches of the 1st ( 24,1-41,3 %) and 2nd order (21,7-55,0 %). Pre-sowing seed treatment and plant growth regulators alfalfa sim- triazine series contributed to the increase in seed yield of 15,5 %. On average, the yield of green mass increased by 0,8-2,4 t /ha or 5,2-15,5 % and seed yield at 0,19-0,42 h/ha or 8,7-19, 3 %. Growth regulators of sim-triazine series increase the protein content of the vegetative mass of alfalfa at 3,2-4,6 %
