The influence of means of chemicalization against phytophagos on the yield capacity of the spring rape seeds under conditions of the southern partially-wooded steppe of Western Siberia

This article is about the results of the research of the employment of means of the chemical protection against the pests under conditions of the Southern partially-wooded steppe of the Western Siberia. An extensive description of the methods of research is made. In these results specific features of the running experiment were sounded, the structure of the crop rotation was shown, some variants of the carried out agrotechnical measures are defined. The role of rape in the crop rotation and the importance of growing of this crop for agriculture is also described. The description of the yield capacity of rape to the conditions of the sharply continental climate of the Southern partially-wooded steppe of Western Siberia was presented. The influence of different chemical preparations (herbicides, fungicides, insecticides) on the crop of rape is studied. In the article the short information about the species of pests, the populations of which were damaging areas under crops of rape during the seasons of the research, was presented. The detailed description of the applied systems of fertilizers, herbicides, fungicides, insecticides was presented; the optimal dose of applying working substances, used in this experiment was defined. There they estimated the weather conditions for the last two years of research. The description of the growing sort, its origin, morphological features, advantages and the nature of interaction with chemical weed and pest killers is made. The comparative analysis of the crop capacity of different variants according to the treatment by the chemical preparations and characteristics of the climate conditions was shown. As a result of the taken research, some variants, which showed the best result, higher crop capacity relatively some other variants, including the complex of application of chemical preparations and carrying out of agrotechnical measures were revealed. The efficiency of the applied preparations and the necessity of further research of this agrotechnology is proved on the strength of the proofs of the yield capacity of the spring rape according to the results of two years.
