There were considered the morphological traits and biological peculiarities of rice which should be taken into account at this plant cultivation working out with the aim of getting of maximally high yield at excellent grain quality. There were marked the rice varieties for different conditions of growing
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
Remineralization of leached black soil was carried out by making such rocks as loess-like loam, shell limestone, apatite phosphogypsum. It was revealed, that the introduction of species did not change substantially the content of boron during the growing season. The manganese content in relation to the control increased by 13-15%, 25-30% for copper, zinc, 35-45%, 25-30% cobalt, and molybdenum in 2-3 times, and especially when combined application of rock. Seasonal dynamics was expressed, but does not give definite pattern
In the article, the estimation results of reproductive, fattening and meat qualities of pigs of various types of nervous activity and state of cardiovascular system are given. The degree of influence of nervous activity on productive pig qualities has been shown
The article highlights the main aspects of the system of formation and reproduction of the resource potential of agricultural production. A number of systemic laws in relation to the process of reproduction study resources
The article is dedicated to the problem of different fat additives use in the rations for agricultural animals and poultry
The article presents the research results of eight grapes rhizogenesis of different genetic origin of the cuttings after treatment with 0.01% solution of IAA for 24 h. It was found, that the activity of regenerative processes in grape cuttings depends on the varietal characteristics, storage conditions and the activation of IAA. It leads to disruption of existing natural correlations, including suppressing the longitudinal polarity. Root-growing ability of cuttings is a genetically determined feature: the effect of IAA did not cause the stability of the positive reaction; it is determined by genotype and depends on the quality and physiological condition of the cuttings
The results of studying of influence of ways of sowing sorghum hybrids have shown that with increase in width of row-spacing, the crop of green weight and hay decreases, the high-quality crop of green weight is formed in the exit beginning in a tube
This article reviewed the results of analysis of a balance of nitrogen, phosphorus and potassium in chernozem (typical black leached soil of Belgorod region) after two crop rotations by different cultivation technologies of agricultural crops. The balance of nutritional elements has been calculated and the optimal agro technology for deficitless balance of plant nutritional elements determined
The article reviews the results of studies of adaptive properties of the hybrid corn of different groups of maturity at the background of anthropogenic factors. It discusses the practical application of research results in order to maximize grain yields from 1 ha, environmentally friendly products (including at cultivation of corn on the protected areas), economically viable crop with maximum return on investment, as well as the possibility of extensive corn cultivation technology with limited material resources-money producers
