Development of innovative projects and technologies in manufacture

In the aim of  implementation of a decree of the President Islam Karimov from July, 15th, 2008 « About additional measures on stimulation of introduction of innovative projects and technologies in manufacture » Scientific research institute of soil science and agrochemistry of The Republic of Uzbekistan, Tashkent State agrarian university in cooperation with the Center of science and techniques under Surkhan-Darya region carry out the innovative project « Development of measures on an effective utilization of the irrigated grounds of the Surkhan-Darya region, increase of fertility of the irrigated areas of farm enterprises ».

The basic purpose of the given three-year project consists in restoration, preservation of fertility of the irrigated areas, development of the new grounds, use of additional water sources, introduction corresponding agricultural equipments. In opinion of experts, as a result ofcotton monopoly during the Soviet period it has been broken general biological balance of the sowing grounds. The level of underground waters has risen, salinity of ground has increased.

- Such situation seriously disturbed experts, - said Director of the Center of science and techniques under Hakimyat of the Surkhan-Darya region, professor Chori Saidov. - the Decree of Head of the state from October, 29th, 2007 about radical perfection of system of meliorative improvement of the grounds promotes acceleration of work on elimination of existing problems. The innovative project « Development of measures on an effective utilization of the irrigated grounds of the Surkhan-Darya region, increase of fertility of the irrigated areas of farm enterprises» not only promotes meliorative improvement of a condition of the grounds, but also gives a scientific substantiation to growth of productivity. In this plan appropriate recommendations will be developed.

On available data, in theregion there are 25 thousand 300 hectares strongly salted, 45 thousand 800 hectaresmedium salted and 88 thousand hectares few salted irrigated areas. According to the innovative project in the past year it was conducted research works in associations of water-users named after Abdulla Nabiev in area Muzrabadskom and «Talashkon» of Sherabad area, which was chosen as monitoring experimental areas.

The experimental platform in the association of water-users named after Abdulla Nabiev has an average level of salinity. Experts have revealed a kind and mechanical structure of ground of areas under crops, the general and mineral structure of nutritious elements of ground, its water-transmissivity, a level of humidity and other factors interfering growth of productivity. In the association of water-users «Talashkon» it was investigated the influence of system of a replaceable crop rotation of a cotton and grain on fertility of ground and efficiency of replaceable crop is scientifically proved. On the area where four years grain was successively grown up, decrease in productivity was observed. After harvesting on the areas with replaceable crop of a cotton and grain, at deep plowing and repeated sowing, growth of granularity of an arable layer of ground is revealed.

By results of experiences it was given recommendations to the farms, nowdaysit is carrying out measures on increase of productivity. Experts continue scientific researches within the limits of the innovative project. Alongside with carrying out of field experiences the chemical analysis of samples of ground is conducted. Results show, that one of major factors salted ground is continuous use of water from the salted channels. The next year researches concerning to a level of humidity, a mineralization of water, a level of salinity of ground, flowing waters, and also dynamics of agrophysics, hydro physical, agrochemical and hydro chemical properties of ground will be carried out.
These scientific researches, experiments, cooperation of scientists and farmers will undoubtedly promote sharp increase in productivity and in the end of the result - to the further growth for the well-being of the population.
