The results of three years experiments of using local mineral raw materials such as bentonite clay as ferti-lizer are given in this article. Autumn bentonite appli-cation in the dosage of 10 ton/hecht has given 21,7% crop addition. Usage of N30Ph30 and N60Ph60 on this background has assured addition up to 32,6-34,1%
Eight-year research data of crop rotation of new
six-field crop rotations and energy-saving methods
of their cultivation are presented in the article. More productive grass- grain ploughing crop rotation and energy-saving means of main soil cultivation, rates
of fertilizers and regime of irrigation, increasing productivity of agricultural lands, keeping fertility
and biodiversity of irrigated agro landscapes were revealed.
In this article the perspective of using Lignas and Lavarin microfertilizers, which increase milt of winter wheat and give economical effect is shown
It is important to use tank mixtures of chemical weed killers with the biological preparations straight after the compounding. The Difesan doesn’t affect negatively on the viability of the Azothobacter chroococcum and Bacillus musilagenosus bacteria. Biological preparations in mixture with weed killers improve the yield productivity a lot
Five-year data of the influence of direct affect and the post action of decomposed turkey droppings on the sunflower husk on crop productivity in three-level field crop rotation of spring barley - sunflower -spring barley and in a comparison of its action with the effect of fertilizers on crop yields were presented in the article. The affect of the droppings exceeded affect of mineral fertilizers on the productivity of field crop ro-tation link in a dose of N90P90K90 on 0,79 t/ ga or on 16%
Grapes are product of areas. Grape plant is very plastic
and can grow on almost all types of soils except highly
saline, fusion and wetlands. In studies of many
authors, it was indicated the influence of different soil
types and their properties on the growth of the vine
plants, the quality of berries and their products. The
object of study is soils and vines growing on them,
laws and processes affecting the formation of grape
production. Research methods are expeditions, field
and laboratory. The article presents data on the effect
of agrochemical soil properties (pH, solid residue, the
amount of aqueous extract ions, chlorine ions,
alkalinity (НSO3¯), calcium ion, magnesium ion, total
carbonate, active carbonates, nitrate nitrogen, mobile
phosphorus, exchangeable potassium , humus, humus
reserves) on the formation of the harvest of grapes and
wine products (tasting score, the extract, the amount of
phenolic compounds, the amount of organic acids, the
amount of amino acids, metal ions, potassium ions,
sodium metal, magnesium ions, calcium ions, the
amount of metal ions). With the help of statistical data,
we can establish the effect of weather conditions on the formation of 2009-2011 qualitative wines of
Cabernet Sauvignon
This article presents the data of the research of new
feed additives’ effects on the dynamic of
hematological indexes and milk productivity of cows
To solve the problems of full-value feeding for pigs, it is offered to use protein-vitamin-mineral additives as a component of rations. It allows increasing live weight gain, average live weight gain and improving feed conversion efficiency per 1kg of live weight gain
The article provides the data of the researches of studying of samples of haricots varieties and selection the highest yield for the conditions of the Azov zone of the Rostov region, and also their economic assessment
In article the review of results formation productivity as well as features bioenergetic and economic efficiency cultivation of mid-season hybrid of corn Valentin depending on the variant of primary tillage (in common Harnes with Luvaram and Titus with Harmony) under conditions of sufficient moisture zone of the Central Ciscaucasia is given.
