ECONOMICAL EVALUATION OF GRASS-HERBAGE LEGUMES DEPENDING ON SOIL PROCESSING AND GRASS MIXTURES

Abstract

Traditional technology of development and use of cultural mixtures on sloping lands suitable for  grasslands require certain modifications and replacement of  modification due to high energy and resource costs, shortage of harvest, its quality and costs.

We present the results of studies that have shown that an important factor  in increasing the efficiency of meadow forage production on sloping lands are pretillage and composition of grass mixtures and their ekonomic evaluation.

It is established, that the highest income (4308 UAH/ha)  and the profitability (116 %) are obtained  on areas where milling was carried to a depth of 10-12 cm and the grass mixture consisted of Phleum pratense L., Agrostis aiba L., Festuca orientalis Kern., Lolium perenne L., Galega orientalis L.,Trifolium hybridum L., Medicago sativa L. on the  background of fertilization N₆₀P₆₀K₉₀. The lowest yield was observed for variants of the same grass mixture and zero tillage cultivation: - 3392 UAH/ha  and profitability 93 %.
