In this article, the orderliness of the wheat plants phytomass increase has shown, observed until plants growth stopping time, which concurs with flowering ending. The discovered orderliness determinates the nitrogen, phosphorus and potassium (N, P, K) transfer dynamics. The mathematical model of N,P,K elements carrying out from roots - inhabited soil layer has been proposed
We have studied the growth of larch plantations in the Republic of Mordovia in order to assess the breeding and selection of candidates for plus trees
Under conditions of vegetation experiment at soil artificial chloride salinization the dynamics of accumulation and distribution of sodium, potassium and calcium in organs of rice plants (Oryza sativa L.) have been studied, as well as their correlation with tissue hydration in ontogenesis. The significant restriction of salinization ions transport and accumulation, particularly sodium, in the actively functioning upper leaves and panicles has been observed. Whereas the content of calcium and potassium in the experimental and control plants differed slightly
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 article contains the results of the researches on the experimental field in the "Kuban" educational farm of Kuban State Agrarian University. In the black leached soil we defined particle size, the structure and the composition of water-physical properties of the soil, which are the most important conditions for high and stable crop productivity. We also gave morphological and genetic characteristics of the soil
The research has revealed that sodium selenite, vitamin E and bifidumbacterine should be included into the ration of the agricultural poultry to increase its antioxidant status
The author has studied the efficiency of diets with
kiselgura. Introduction of the kiselgura into the mixed
fodder for chicken-broilers favors increasing of live
weight by 4.8 % and average daily weight gain by 5.0%
Future increase of rice productivity is possible in expense of plant change architectonics. Creation of plants with erect position of leaves allows to compact sowings and to increase the productivity of cenosis. There were studied the rice samples with erect leaves and large grain as an initial material for selection on increased productivity
The article presents the characteristics of condition and growth of Pinus sylvestris and Betula Pendula in their cohabitation in poor sand soils (A2) in the condition of some forest enterprises of Voronezh region; the most effective way of combination of this species is revealed
The article presents the results of three years of testing
varieties of soft winter wheat. We have considered their
adaptability to different environmental conditions,
ecological plasticity, stability and homeostatic ability.
The article discusses the characteristics of varieties for
yield and baking qualities
