THE INCREASE IN ENERGY GROWTH CALF IN DAIRY PERIOD
06.00.00 Agricultural sciences
Description
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%

Description
The effects of tillage, minimum and combined treatment on the structure of the southern black soil and crop yield of such winter wheat as Tanais, and Petrovchanka Ayvina have been studied. It is revealed, that the most stalwart and giving more than the number of productive stalks is a sort of Petrovchanka. The highest yield of winter wheat was obtained with plowing, and the lowest - with combined processing unit. The most productive variety was Petrovchanka.s

Description
In the arid zone of chestnut soils in Stavropol territory, sunflower was cultivated, using different types of primary treatment: plowing, scuffling and moldboardless processing in the depth of 10-12 and 20-22 cm. It was found out, that different treatment methods do not affect the content of nutrients. The density and porosity of the soil was relatively favorable, as in the treated and untreated soils

Description
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

REGENERATIVE PROPERTIES OF GRAPE CUTTINGS UNDER THE INFLUENCE OF TREATMENT WITH IAA
06.00.00 Agricultural sciences
Description
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
