Zabarna T. Forage productivity of red clover varieties depending on the type of growing and fertilizing in the conditions of right-bank Forest-steppe of Ukraine

Objects which are researched are the process of the formation forage productivity of red clover varieties depending on the type of growing and fertilizing. The goal for our research is the finding dependences of forming forage productive of red clover varieties depending of fertilizing and type of growing. Methods of the research: visual and weight; physiological; biochemical; statistical; rather. Peculiarities of the growth, development and formation of photosynthetic, symbiotic and forage productivity of red clover varieties depending on the type of growing and fertilizing are presented in the thesis, besides the economic bioenergetics' evaluation and the evaluation of technology competitiveness are given. The obtained and generalized material enables to recommend and to introduce into production the most economically profitable and the most competitiveness technology of growing red clover in the conditions of right-bank Forest-steppe., which provide the leaves and stems mass output of 31,14-32,97 t/ha during the second year of life and 21,64-23,95 t/ha during the third year of life. Thus output of dry matter, accordingly, was 6,29-6,61 and 4,17-4,59 t/ha. Science researches have been passed the stage of the Vinnytsia region agronomics forming ("Nadiya", "Promin'") at the general area of 70 hectares. The sphere of using is the agriculture.
