Based on the results of field experiments in 2015-2017 on winter soft wheat varieties, the yield error was 0.64-0.98 kg / ha (НСР05 factor A), and the yield error on application of the urea norm was 0.45- 0.69 kg / ha (HCP05 factor B), which allows us to consider the conducted research reliable.

The result determined by mathematical analysis according to the method of B. A. Dospekhov [4], the minimum difference was up to 0.98 kg / ha, which allows the introduction of large-scale practical farming with urea solutions physical 40 kg / ha per 300 l / ha of water in the beginning phase embryonic development of varieties of winter soft wheat Yaksart and Gazgan through the leaves. 

The article discusses the features of microbiocenosis in pesticidecontaminated soils of Karakalpakstan. The results of studies in the region show that soil pollution with pesticides and salinization changes the ratio between individual groups of soil microorganisms and leads to a depletion of the species composition and the dominance of the most adapted to pesticides, salinization of microorganisms. Reduced biodiversity with a predominance of certain groups of soil microorganisms indicates low environmental sustainability. 

in this work, studied and developed a computing cluster, consisting of one head node and four computing nodes based on homogeneous computers based on HPC technologies, to implement distributed processing algorithms for two-dimensional signals. As cluster management software are used the Windows HPC Server 2008 R2 operating system and the HPC Pack 2008 software package with cluster operation utilities. As the results of research and computational experiments are given results of performance evaluation of the distributed signal processing algorithms in a computing cluster based on wavelet functions. 

This paper analyses about designing methodical recommendations and using them in providing normal indicators during the exploitation of auto transport to improve traffic safety in transport. 

The task of calculating the annual, current plan of the oil extraction plant belongs to the top level of the hierarchy of the integrated production management system. At this stage of management, as a rule, when formalizing the process of volumetric production planning, we use the method of converting a set of technological operations to a single operation — to transform initial products into final ones. In our work, we used a slightly different approach. In accordance with it, the continuous multistage production process of an oil extraction plant for the purposes of volumetric planning and management of the aggregation method is reduced to two generalized operations - ―PRESS‖ and ―EXTRACTION‖. It is proposed to manage (plan) the process according to a two-step scheme - in accordance with the number of generalized operations. The presentation of the production system in the planning period according to a two-stage scheme, taking into account the production of intermediate products (black oil), improves the adequacy of the planning model and, consequently, increases the reasonableness and accuracy of planning. 

The researches on working out the ―Dissolution‖ test for combining capsules of «Koask -30» have been conducted. According to the result of conducted experiments were selected the following conditions for carrying out the ―Dissolution‖ test: determination of dissolution profile 0,1 M hydrochloric acid solution ( within 45 minutes it must be isolated not less than 75% of active substances), medium volume – 1000 ml, speed of rotation basket- 100r/min, temperature regimen -37±10C.
