The article presents the effect of boron fertilizer on growth, development and productivity of rice plants, the optimal dose and timing of application of boron fertilizers, providing maximum increase grain yield, calculated the economic loss of nitrogen, phosphorus and potassium and crop coefficients of their use of
fertilizer plants; we have also established the influence boron fertilizer on grain quality of rice

This review contains the information about the role of annelids in maintaining soil fertility. Recommendations based on authors’ experience and scientific literature are given for vermicultivation,
biomass use of Californian worms in animal husbandry and vermicompost use in crop production. Furthermore, detailed description of the methods of cultivation of worms is given
The article compares the basic biotech properties of beef of new meat breeds and determines the potential of their use
In the article there were presented the results of cultivation of an apple-tree garden with application of growth stimulators. Positive action of Buton and Mival-Agro preparations on grades of all terms of maturing is noted
The polymorphism is the diversity of varieties in ampelografy - the presence simultaneous permanent in the population of two or several phenotypic and genotype differing groups of plants of one variety – i.e. clones. In viticulture the isogenic population is usually called “clone” and variety as the total of clones or forms – i.e. it is heterogenic. Polymorphism of varieties has big practical sense, as varieties-clones have the harmonic complementary adaptive ampelocenosis and higher economical effect for production. In the article the polymorphism of two heterogenic population - the group Pinot and Riesling, which are the best specimen of French and German viticulture is described on the phenotypic level of leaves
Characteristic of financial-economic activity of agricultural enterprises and qualitative land condition is casted in the article. Arrangements connected with biologization of agricultural production are considered and assessment of its efficiency is given.
The regularity that increases biological and enzymatic activity with increasing the age of the deposits of 10 to 82 years has been shown. The indicator of recovery of black leached soil steppes can be presented as invert-ase activity and humus content, as well as reducing the density of the soil. Integrated indicator of the biological properties decreases with decreasing age deposits: 82 years (100%) - 26 years (84%) - 16 and 10 years (74%) - arable land (64%)
The behavior, interior and milk yield of the mature Black-and-White cows with various productivity levels, as well as etology of the replacement heifers are researched. The superiority of the high milk yielding cows for the lying duration and eating feed and water is revealed. Reduced variability of vital behavioral actions of animals is found. In addition, high yielding cows has been lower variability in all feeding acts. It was noted that high yielding animals exceeded equal age cows by the level of most interior factors. The differences were significant on the content of hemoglobin, vitamin E, and especially on the content of iron. Positive correlations between some interior design indicators is found. The analysis of lifetime productivity during our research found that high milk yielding cows had highest yields on the first lactation and kept the same level in the next lactations with insignificant variations. The lower productivity animals reached maximal yields on the third lactation with the followed downward trend. Differences between groups in lifetime productivity during research amounted to 16 992 kg. The significant superiority of the heifers with high grown intensity above equal age animals for the duration of feed and water eating, physiological functions and lying. The analysis of variation coefficient is confirmed the observed regularities.
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
