EFFECTIVE CROP ROTATIONS AND STRUCTURES OF CROPS IN THEM UNDER IRRIGATION
06.00.00 Agricultural sciences
DescriptionEight-year research data of crop rotation of new six-field crop rotations and energy-saving methods of their cultivation are presented in the article. More productive grass- grain ploughing crop rotation and energy-saving means of main soil cultivation, rates of fertilizers and regime of irrigation, increasing productivity of agricultural lands, keeping fertility and biodiversity of irrigated agro landscapes were revealed.

Description
Main scientific results, which were received in 2007 under creation and investigation of semantic information multi mode, providing as detection of dependence between astro signs and accessory of respondents to generalized social categories as a use of knowledge of these dependences for identification of respondents by these categories are casted in the article. Multi model includes 172 private models on 37 generalized categories and each of categories is presented less than 1000 respondents under general fetch capacity of 20007 respondents. It was applied the method of systemic- cognitive analysis, which is considered as one of the universal variants of decision of thirteen problem of Gilbert in practice ( theoretically this problem has been done in the theorem of A.N. Kolmogorova, which is a generalization of theorem V.I. Arnold ( 1957) under it.
