Goloborodko S. Biological and agrotechnical bases of growing of alfalfa for fodder and seeds in the southern Steppe of Ukraine

The object of researches is the process of forming of harvest and his quality at growing of alfalfa on a forage and seeds on earths of south Steppe of Ukraine. Purpose of researches - to set conformity to the law of forming of forage and seminal productivity of alfalfa, to perfect existing and develop energosberegayushie technologies growing of alfalfa on a forage and seeds. Methods of researches - the field; measuring-gravimetric; morphological; laboratory; computation-comparative; mathematic-statistical. Results of researches - for a theory: The agrotechnical receptions at growing of alfalfa on forage and seminal purposes taking into account the biological features of sort are improved, that is used basic factors of influencing, which determine the level of productivity of culture at the optimized charges of energy on 1 ga sowing area and unit of harvest, that allows to forecast the size of energoemkosti of the got products of plant-grower. For practice: rise of gross collection of high-albuminous forage and seeds of culture at the power cost cutting on 1 ts products. The developed energosberegayushie technologies growing of seeds of alfalfa allow to get to 5,0-6,0 c/ga standard seeds with the minimum charges of energy on 1 c seeds. The sphere of the use is the agricultural enterprises of south Steppe of Ukraine.
