In the article, we have revealed the efficiency of sown using of fertilizers, the methods and the doses of additional fertilizing on different maize subspecies growing on the leached black soil of Northern Ciscaucasia which are based on studies in central part of the Kras-nodar region in 2008-2010. We have also given the scientifically-based references of increasing productiv-ity of maize
In the article, we have studied the effect of antibiotics on enzyme’s activity of black soil. Introduction of the high doses (600 mg/kg) of antibiotics benzylpenicillin, nystatin) leads to considerable decrease in enzyme’s activity of soils. The class of hydrolyses is most sensi-tive to the action of antibiotics, their activity decreases for 50-70% from control values, the class of oxidore-ductase is least sensitive (10-40%). Antibiotic’s action on enzyme’s pool of soils has the prolonged character
This article shows the lines for the processing of manure. Besides, the equipment which is necessary for the realization of the process is defined
To solve the problems of full-value feeding for pigs, it is offered to use protein-vitamin-mineral additives as a component of rations. It allows increasing live weight gain, average live weight gain and improving feed conversion efficiency per 1kg of live weight gain
The article reflects the results of the scientific research on creation and implementation of applications in industrial conditions of livestock enterprises of the country. The staff of the laboratory of the development of theoretical bases of selection of animals of Don SAU has created the selective cross-breeding information filter “SIF”. The system is constantly updated with new programs. The analysis of the information accumulated in the system allows to develop the recommendations, to make operational decisions and correct selection of the program
In the article, there are the data of a specific variety of cereal weed plants in crops of winter wheat on a black leached soil depending on the predecessor and the way of processing of a soil and its role as a source of an infection root rot. The greatest number of isolates of mushrooms – causative agents of a disease, was allocated from such weed plants as wheat grass creeping, eras galli, field (chess) brome grass; the smallest – from Lolium temulentum. Fusariosis root decay dominates in community of cereal weed plants
The article presents the analysis of the experimental data obtained during testing varieties of soft winter wheat. Such characteristics as plasticity, stability, homeostaticity, yielding capacity and bakery qualities are discussed
The results of the researches of the technology impact of various intensity levels on the productivity of forage crops in the Priazovskaya zone of the Rostov region are given in this article. Economic effective technologies for each crop are identified
The essential new approach to soil processing taking into account its origin as a geologically disperse body is offered. The soil should be processed not only using its natural dispersion, but also optimizing this geological deposit taking into account decrease in its dispersion in process of a geological and biological sedimentation in the field of weight of Earth. The new technical solution is proposed for rotational intra soil cultivation. The problem is solved to transfer a torque to the tool being inside the processed geological body
Among fungus diseases of rice, blast is the most harm-ful. The disease is caused by Pyricularia oryzae Cav. Rice is sensitive to blast at all fazes of vegetation. In Russia, the purposeful breeding of rice varieties re-sistant to this disease began in 1982. Over the past period, the rice varieties which are genetically protect-ed from blast and not requiring crop protection have been created
