The article is devoted to the investigation of the influence of applying elevators waste to the soil on the content of ions Ca2+, K+, NH4+ , NO3 - and photosynthetic pigments in leaves of plants of winter wheat in the cultivation of the leached black soil
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%
This article summarizes results of the research on the
assessment of soil erosion effectiveness of crops and
the rationale of the practical application of phytomeliorative
actions aimed at improving the erosion resistance
of slope lands. We have obtained values of the
resistance of soils to erosion under agricultural crops
and in terms of pure steam and calculated the indicator
of the efficiency of soil conservation crops. The tests
allowed differentiating the crops on well, poorly and
very poorly in protecting forest soils from erosion
The research about effectiveness of ammonium
nitrate with sowing and in phase of corn 5-6 leaves and row spacing cultivation before straw mulching was done in 2011-2013. The scheme of trial
included the variants with straw mulching and
without it. The variants without fertilizers and with small doses of them on background without mulching gave higher yield of cobs milk maturity then with mulching. But variants with maximum fertilizers (with sowing N30 and in phase of corn 5-6 leaves N30) gave maximum yield of cobs milk maturity 16,4 t/ha that is higher then similar variant without mulching for 1,7 t/ha. These results were confirmed by analysis of characters of growth and development of corn plants, productivity, and economic effectiveness. Therefore, net profit on variant with fertilizers with sowing N30 and additional fertilizing N30 on background of straw mulching increased for 75490 rubles for 1 ha in comparison with similar variant without mulching. The profitability on the best variant was 335 %
The article contains complex research results dedicated
of reproduction the cattle of the animal breeding
industry in the agricultural holding called “Kuban”.
Key indicators characterizing reproductive function at
cows were set; they were estimated in terms of the
plans of the economy in the milk cattle breeding
industry. The reduced values of the birth-rate of calves
were revealed on 100 cows and in the term of the
production use of cows, their main reasons were set.
The performed calculations prove the possibility of
increasing the profitability of milk production
