On the basis of functional processes and life of students, taking into account the daily time fund of consumers, as well as the results of a survey of parents and the design of the experiment determined the model and the generalized daily time budget.
Time budget developed by the example of the consumer group of primary school children on the basis of a standard daily time budget. Revealed the highest percentage duration of certain activities, therefore their weight.
Crossing typologies in the direction of the modules typical daily budget consumers time and temperature conditions of modules will give the desired result — a specific range of the SS. Review of the list of the SS in the context of consumer preferences will identify the most common combinations of situations and the hierarchy of consumer requirements for the composition and structure of clothes to better meet the demand for uniforms [2; 3].
It should be noted that the intersection of the procedure should be performed whenever the formation offunctional-consumer complex at this period of time. This is the advantage of this method and situational design uniforms.
The grouping of the nomenclature of the consumer situation and the means of their objective to ensure it provides the opportunity to supplement, change and development, depending on the changes and development of the real life of people in the system «man-wear- environment».
In the second stage of the work carried out on the formation of a rational wardrobe of uniforms and basic types of sets for the identified situations, the establishment of consumer and industrial requirements for types of products under development.
Thus, the consumer situation is the basis for the development of optimal nomenclature and assortment formation of groups of species and varieties of children's products on the basis of design and typological approach and functionally-consumer complexes using methods and design tools. Formation range of children's products and its purpose must be based on a synthesis of consumer situations and consumer preferences. To operate this information is necessary to conduct market research and practical application of the study of the daily time budget.

Power-efficient method of tillage and its technology model
At present time soil tillage for sowing and crops preparation are mainly put into practice by means of traditional technologies and engineering tools, that is plowing firstly, harrowing and leveling secondly, after which ridges are cut. Such multi-step tillage provokes big labor inputs, expenditure of energy and fuel, delays sowing time
that results in yield drop of agriculture.
On the assumption of the above-stated we have developed a new tillage technology model for cotton-plant sowing and a component unit for its implementation.
Figure 1. Component unit design
Figure 2. Component unit operating procedure a - ridges before the unit run; b - unit operating procedure; c - generated new ridges
The engineered unit is composed of (Fig.1) chassis 1 with mounted element 2, rippers 3, fertilizer plows 4, ridge-forming tools 5, chemical fertilizers feeder 6 and support wheels 7.
The unit in a run mellows the bottom of the last years' irrigation furrows at a depths of30-40 cm (Fig. 2, a and b), moulds the old ridges in furrows, moulds new ridges (Fig.2, c) dressing them with two-layer strip ofchemical fertilizers. In that way, the new ridges are cut due to demolition of the old ridges and soil slip to the area of old ridges (Fig.2, a).
At the same time a layer of loose soil of 55 -65 cm depth is formed as compared to 30-40 cm in the case of plowing. In spring the ridges are touched up and chemical fertilizers are dressed for cotton-plant sowing. Thus there is no need to carry out such traditional operations as harrowing, chisel plowing and leveling. Consequently, fuel consumption and labor inputs are reduced.
Soil tillage is carried out sinusoidal along the frontal projection. Because of this the soil structure is disturbed only once in two
years. Loose soil area is formed under the ridge that ensures mois- Realization of the new tillage technology gives an opportunity

Substantiation technological and design data сошника for crops of seeds of winter wheat in cotton row-spacing
Abstract: The article presents the theoretical study of materials on substantiation of technological and design parameters of the coulter for seeding winter wheat seed cotton in the aisles.
Keywords: knife; working-organ; wings; seed-funnel; multi-crop in the aisles; groove profile; optimum density; efficiency; productivity.
For crops of seeds of autumn wheat in cotton row-spacing offers a new working-organ (drill colter). Novelty of the technical decision is protected by patent UZ FAP 00722 [1].
Proceeding from the received patent, it was necessary to prove technological and design data of a new working-organ (fig. 1).
Figure 1. Schemes working-organ, a copying and forming row-spacing of cotton 1 - beam, 2 - lock, 3 - racks, 4 - and 5 - wings, 6 - seed-funnel, 7 - knife
The offered new technology and design сошника carries out multi lower case crops from 5 (for row-spacing of 60 sm) to 9 (for row-spacing of90sm) рядков. At the expense of formation of the new friable form of a furrow of a row-spacing the useful area of crops of seeds on 9 ... 22% in comparison with strew increases in the way, is provided conditions for uniform crops and reception of amicable shoots.
For maintenance of the new, slightly condensed form of the furrow demanded uniformity of depth of crops, working-organ in the course of work should be constantly to nestle on a row-spacing surface that is the condition [2] should be met.

Where: ро — density of soil of a row-spacing after preceding processing, g/sm3;
hi — depth of preceding processing, m; ho — depth of immersing сошника, m.
Hence from the formula (1) we can define depth of immersing working-organ

At following values of density of soil p =1,2 ... 1,3 g/sm 3, p0=1,0 ... 1,1 g/sm 3 under the formula (2) depth of immersing сошника it is found in limits 2,0 ... 4,0 sm.
Height ofwings working-organ we will define from a condition not over turning layers of earth through the bottom part
