In the article is given results of research conducted at the Yakut scientific research Institute of agriculture. We study the effect of three sowing terms on the yield of promising annual forage crops. The results of studies on growth, development, yield, nutritional value and economic evaluation of prospective annual crops are presented.

The results of experiments carrying out for identifing the harmfulness of the mulberry fire on the mulberry leaves are presented. It is shown that we can reach the biological efficiency up to 88% when lacewing entomophages in the ratio of lacewing and mulberry fire eggs and larvae to 1:5 are used.

The object of research was 20 maize hybrids, bred by the Voronezh branch of the All-Russian Research Institute of Corn. The aim of the work was a comparative assessment of maize hybrids on the main feed characteristics when cultivating them in the agro-climatic conditions of the Republic Mari El. As a result of biennial studies it was revealed that among the studied maize hybrids cultivated on green mass in the territory of the Republic Mari El in 2015 the best feed characteristics had hybrids: Voronezh 185-15 (16342 f.u./he), Voronezh 173-12 (17554 f.u./he), Voronezh 189-15 (15134 f.u./he), Cascade 195 NE (15134 f.u./he), Voronezhsky 193A-15 (16215 food units/he), Voronezh 195-15 (15276 f.u./ he), which synthesized 50-60 tons of green mass per hectare of sowing and accumulated 15,2-17,7 tons of dry matter. The greatest grain yield among the studied maize hybrids was noted in the Voronezhsky 191-15 and Voronezh 158 CB hybrids, which formed 13,7 and 16,3 t/he of grain with a moisture content of 35% and 36,1%, respectively. In terms of the standard moisture content the cereal productivity of these hybrids was 12,9 and 14,5 t/he. Under the conditions of 2016 the best feed characteristics were observed in hybrids of VTG 173-12, VTG 195-15, VTG 189-15, VTG 26916, VTG 185-15, which synthesized 33,3-39,4 tons of green mass on hectare of sowing, accumulating 9,49-12,42 tons of dry matter. The greatest grain yield among the studied maize hybrids was noted in the Cascade 166 ASB hybrids (9,78 t/he) and VTG 270-16 (10,12 t/he). The moisture content of the grain during harvest was 29,98% and 35,6%, respectively.

The article presents the results of research on the dynamics of the formation of leaf area, photosynthetic potential, the accumulation of dry biomass and net productivity of photosynthesis of durum wheat sort Krupinka depending on the terms and rate of sowing in the irrigated lands of the southern region of Uzbekistan.

The article presents the data on the digestibility of nutrients of bull-calves of Kalmyk breed diet at different levels of feed additive «M-Feed». Experiments determined that the most effective action is created when added to the diet of bull-calves for meat production a new feed additive «M-Feed» in the quantity 5 g/kg ration dry matter. This is a real basis for the manifestation of the biological capacity of animals organism, which was confirmed in scientific-economic experience.

One of the main perspective directions in technology of pigs feeding and the development of the industry is the use of enzyme preparations. Study the possibility of joint use of mixture of enzyme preparations and their impact on animal organism is important. The results of studies on the use of mixtures of enzyme preparations of domestic production amilosubtilin G3x and cellolux-F and amilosubtilin G3x and protosubtilin G3x in mixed feeds for young pigs at growing and fattening are presented. The use of such mixtures increases in digestibility of feed nutrients and the intensity of metabolic processes. Higher figures were obtained when use amilosubtilin G3x and cellolux-F.

It is pointed out the urgency of improvement the bitering dosing organ of the mobile feed dispenser with reference to their prospects, taking into account a new technological and planning projects for cattle farms. The process of determining the feed from the monolith in the hopper of the feed dispenser with the combs of the biter device is studied. Based on the calculation formulas, which are treated by considering the problem in the order of elastic deformation and determining the force of the beater combs to separate the feed in the feeder bunker, an assessment is made of the work of the dosing organ of the mobile feed dispenser. The presented calculation technique allows choose the effective parameters of the beater, which ensure the quality of the process at the minimum energy consumption.

A new design of furnace for burning agricultural waste with the best performance in comparison with analogues.

In the article the level of security of agricultural organizations by heads, specialists and a personnel of working professions is considered. It is revealed that the most scarce is a personnel of working professions, their shortcoming is aggravated in the considered temporary period. The demand pattern on replacement of vacant positions of a personnel of agricultural organizations is studied. Quality characteristics of a personnel are studied: age, education level, qualification. It is established that the developed level of security and qualification of a personnel of agricultural organizations doesn’t correspond to requirements of production, acts as the factor constraining development of an industry on an innovative basis.
