Abstract

The article presents influence of different information technologies of cultivation on the elements of the photosynthetic activity of crops and the structure of of winter wheat yield. It has been established that, at raised bed of technology of cultivation plants develop strong assimilation apparatus to 48.5 thousand m2 / ha of dry substance and accumulate up to 1285 g / m2 in the interphase period "tillering- milk ripeness." Winter wheat cultivation on raised bed of technology in irrigated conditions in South Kazakhstan has increased by 12.5% in grain yield compared with traditional technologies of cultivation.
