Influence of the way of crops on biometric indicators and efficiency of hybrid forms of corn in the conditions of the Amur region

In article the problem of increase in crops of corn in the conditions of the Amur region, and bringing the areas of corn crops to 100 thousand hectares against 20 thousand hectares is defined. It is connected with prospects of cultivation of important fodder culture. The analysis of grades and hybrids of corn is given, the agronomical and economic analysis of application not only separate agrotechnical receptions, but also all their complex representing technology of cultivation is provided. The technique of researches in which the experiences put on the skilled field of the Far state agricultural university (Far East) GAU on a meadow chernozemovidnoy to the soil are described is presented. Results of researches of influence of ways of crops of hybrids of corn on biometric data and a biological harvest are given. Recommendations about use of ways of crops of corn are made, data on dependence of productivity of grain and productivity of green material of different grades and hybrids of seeds of corn from ways of crops are submitted. For obtaining high productivity of grain the concrete sizes of row-spacings of seeding of corn are recommended. The conducted researches demonstrate that in highly productive agrotsenoza the biological potential of one of the leading forage crops of Priamurye can be 2.0-2.5 times higher thanks to the choice of an optimum way of crops of perspective hybrids. In the conclusion concrete hybrids of corn for conditions of the Amur region, an optimum way of crops at cultivation of corn are recommended for green material and for obtaining the greatest productivity of grain.
