The article reviews the results of studying the adaptive potential of hybrids of corn maturity of different groups in the Central Caucasus. It discusses the variation of adaptive traits of maize hybrids (ecological plasticity and stability of the manifestations of agronomic traits), as well as stabilizing the yield of corn on an annual basis in the processing of seed preparation "TMTD-plus", which contains in its composition Krezatsin growth regulator
The research results of minimization of negative herbicide after-effect on winter wheat root system formation and damage by root rots are reviewed in this article
On the basis of studying of collection of sorghum, the samples with important signs and properties for use in selection are marked out. Sterility fixers are defined as a result of studying of the samples on CMS, and sterile lines with the high combined ability are created
We present a brief description and analysis of the weather conditions of 2005-2011 in North, Piedmont, and the Kuban Krasnodar fruit zones. In the course of many years of research, the optimal conditions for precipitation of water supply as one of the most im-portant factors in increasing the productivity of agro-phytocenoses in the region
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%
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
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
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
