DYNAMICS OF MOISTURE IN SOIL AND EFFICIENCY OF ITS USE BY SOY BEANS UNDER DIFFERENT WAYS OF MAIN SOIL TREATMENT AND DOSES OF MINERAL FERTILIZERS

abstract 1191605040 issue 119 pp. 553 – 566 31.05.2016 ru 343
In the article there were given the results of researches for 20110–2012 obtained of many years stationary experience of the chair of general and irrigated land management of Kuban State Agrarian University on study of main soil treatment influence and doses of mineral fertilizers under soy beans on dynamics of moisture in soil and efficiency of its use by this cultivar. There was determined that from all studied variants the ploughing on 20–22 cm led to the higher accumulation of moisture for autumn-winter period. The decrease of productive moisture reserves on 6-9 % was observed on the types with surface treatment and direct sowing. The increase of soil treatment depth and doses of mineral fertilizers promoted to the better accessibility of moisture during vegetation period and correspondently to their greater expenses. Moreover, there was revealed the more rational use of water by soy beans under mouldboard soil treatment and introduction of mineral fertilizers in the dose of N90P120, it discovers the high effectiveness of present agricultural methods. The highest productivity of soy beans in the experience was achieved by means of ploughing on 20–22 cm and introduction of mineral fertilizers as a main type of soil treatment

INFLUENCE OF MINERAL FERTILIZERS ON EFFICIENCY OF HYBRIDS OF SUNFLOWER

abstract 1231609093 issue 123 pp. 1353 – 1367 30.11.2016 ru 273
Results of researches on studying of various doses of mineral fertilizers on efficiency of hybrids of sunflower Vulcan, the Arena, the Brio and the Signal are given in article. Researches showed that depending on formation of biological mass of sunflower reserves of productive moisture decreased that was a major factor in productivity formation

INFLUENCE OF WAYS OF MAIN SOIL TREATMENT UNDER SOYA BEANS ON CHANGE OF AGROPHYSICAL INDEXES OF LEACHED BLACK SOIL

abstract 1091505057 issue 109 pp. 837 – 847 29.05.2015 ru 652
There were cited the results of researches for 2010-2012 obtained in the stationary experiment of the chair of general and irrigated land management of Kuban State Agrarian University on the study of influence of the system of main soil processing under soya beans on the dynamics of main agrophysical indexes of leached black soil: on density of composition, solidity, general porosity, coefficient of structural properties in the article. There was stated that in the beginning of vegetation on the background of direct sowing of soya beans, the soil layer in 0-30 cm was characterized by values of density and solidity and in the result of it we observed the weak development of the root system. The worsening of air regime led to the decrease of symbiotic nitrogen fixation, it negatively affected on the growth and development of a cultivar. Agrophysical indexes brought nearer to optimal on variants with disposal tip on 20-22 cm and disk-shaped hulling on 8-10 cm. The worsening of investigated agrophysical soil indexes has been happened since the phase of florescence – soya bean formation till the harvesting. But the variant with disposal tip where we observed the high content of agronomically valuable fraction at the coefficient of structural property 2,42 was the closest to optimal ones. The minimization of soil treatment and especially the denial from its implementation significantly made worse the main agrophysical indexes of soil on variants with direct sowing to critical values for soya beans

INTERMEDIATE CROPS AS A FACTOR OF BIO RICE PRODUCTION

abstract 1031409082 issue 103 pp. 1204 – 1212 30.11.2014 ru 798
The article shows the results of years of research, which showed that the intermediate culture - is an important factor in the impact of increasing the fertility of meadow black soils, meadow (rice) soils perform environmental, agronomical and soil protection roles, as well as they are involved in the biological cycle of nutrients
