Decreasing of noise level depending on park plantings structure parameters is reviewed in this article. The connection between noise level and these parameters is shown. Equation allows calculating its decreasing at the stages of park designing and reconstruction is revealed
The analysis of frequency and distribution of chiasma of interspecific tomato F1 hybrids at meiosis prophase I was given. The character of synapsis in anther mother cells of interspecific tomato F1 hybrids was determined; the number of distal and interstitial chiasmata was calculated. The samples, recommended for their inclusion into the selection process as the inducer of genetic variability were chosen
The ways of erosion displaying intensity estimation and soil-protective action of a vegetative cover which will provide increase of agricultural crops productivity, fertility of the agricultural appointment soils and will generate conditions for the degraded agricultural grounds self-restoration are resulted in the article
The detailed morphological description of interspecific tomato F1 hybrids is represented in the article. The positive heterosis in regard to sire component was noticed in accordance with the following characteristics: fruit size, leaf size and stem length. It was established that the inclusion of tomato of Lycopersicon cheesmanii typicus genus into selection enables the obtaining of new species at the expense of increasing the range of genetic variability
In article results of influence of various types of hybrids on efficiency of a sugar beet depending on cleaning terms are resulted, and also their economic estimation is given
The results of researches of influence of different irrigation modes on productivity of cultures and efficiency of use of irrigating water at cultivation of potatoes, cabbages, onions, tomatoes and cucumbers in the conditions of an irrigation are resulted in the article
The method and results of forecasting of crops of agricultural crops in the Rostov region on reclamated lands are resulted. The method is based on use of dependence of crops of agricultural crops from agro meteorological factors. Results of calculation on planning crops of winter wheat at irrigation are shown
CULTIVATION OF VEGETABLE PEAS OF VARIOUS TERM OF CROPS ON THE IRRIGATED SOILS OF THE SOUTH OF RUSSIA
The efficiency, the vegetative period, duration of cleaning of grades of vegetable peas of various term of crops on the irrigated soils of the South of Russia are resulted in the article
Criteria of an estimation and a condition of antierosion actions on various types of the agrolandscapes providing the termination or minimizing of erosive processes of soil and increase of productivity of erosioned unproductive soils are resulted in the article
In the article, the results of researches on influence of various agrotechnical receptions on prod-uctivity and quality of a winter wheat on a cornon-grain predecessor are resulted
