The aim of the research work is to increase the productive capacity of the sands of Central Fergana, to improve anti-erosion technologies, and to develop new agrotechnologies for the care of crops.
Scientific novelty of the research worlds as follows:
For the first time, the improvement of agrophysical and agrochemical properties as well as nutritive regime of sand areas with a natural screen as a result of leaving of rye stubble of 14-15 cm height is proved;
The increase in yields of cotton and other crops included in the cotton complex on deflated hilly-barkhan and sandy lands is determined underapplication of effective norms of mineral and organic fertilizers;
The technology of water saving and improvement of the ecological and reclamation state of sandy lands by creation of natural and artificial screens is developed;
It is determined that as a result of creating natural screens in cotton fields of farms, the cotton boll are opened for 3-4 days earlier compared to conventional method;
A technology has been developed for the use of drainage and irrigation ditch deposits through measures aimed at improving the ecological state of the environment.
