Ahmed A. The efficiency of the hybrids of a corn in dependence on fertilizers and a plant stand of the plants in conditions of Egypt

There is a selection of the most adapted hybrids of aboriginal and foreign selection, among the ways of realization of potential of the efficiency of corn, and also the development of elements of technology at cultivation in conditions of the Arabian Republic Egypt. Genetically different three hybrids are investigated: the Egyptian selection one-linear 10, the American - three-linear 2147 and the Ukrainian - Karpinskiy 1 at different levels of a mineral nutrition, density and uniformity of standing of plants in coenosises. For the first time in these conditions features of growth and development, physiological, morphological and biological features of formation of a crop of hybrids of corn in dependence on the applied technology's elements of cultivation are investigated. Quality indicators of a grain have been appreciated. The ecological expediency of the cultivation of different hybrids of corn has been proved at optimum density of crops and levels of a mineral nutrition.
