The influence of technological methods of growing on the formation of the yield of sainfoin in conditions of the Right-bank Forest-Steppe

Abstract

Goal. To study the peculiarities of the formation of the yield of the vegetative mass of sainfoin depending on the elements of the technology of its cultivation. Methods. Field experiment, measuring, and calculation — to account for yields. Results. In the process of increasing the vegetative mass of plants of sainfoin varieties, its more intensive growth occurred during the formation of the first hay cutting. The intensity of the increase in aboveground mass during the formation of the second hay cutting was almost twice lower. The most productive variety was Ametyst Donetskyi for the use of intensification measures, including inoculation and use of fertilizers. Conclusions. In the soil-climatic conditions of the Right-Bank Forest-Steppe at cultivation on low-humus typical chornozems sainfoin of the variety Ametyst Donetskyi forms the maximum yield of vegetative mass at the level of 43.03 t/ha for 2 hay cuttings when applying complete mineral fertilizer in the dose of N45R60K90 and pre-sowing inoculation of seeds with Ryzotorphin.
