Example text

In modern conditions, creation of seed grass is necessary, especially in mountain conditions on slope lands, where soil and micronutrients are wiped out. Known technologies of legume cultivation include additional fertilization of grass by molybdenum [4]. Molybdenum facilitates increase of nitrogen fixation, development of plant, and in the final result increase of seed yield of clover. A method is proposed to sprinkle the plants by molybdenum–acid ammonium [5]. But several other micronutrients are necessary to increase the activity of tubercles.

In the flowering phase, the content of these substances slightly decreased, but it was relatively high in comparison with zoned cultivars. 8 percent of phosphorus, 2–4 percent of sugar, and 8–10 percent of ashes, which was slightly above the qualitative characteristics of selection samples grown in an elevation of 600 m above sea level (village Mikhailovskoye). It is important in the selection process of the red clover to create basic material with increased resistance to diseases, especially to root rot, anthracnose, leaf spot of clover, and mildew.

These legumes oppress each other in the mixed crop, especially on the second year of life. In the first year after joint sowing those grasses are yet poorly developed. As a result soil erosion takes place. We have used wide-space method of undersow of alfalfa seeds under the grass of clover of the second year of life [6, 7]. Peculiar to legumes hardness of seeds has a significant influence on their germination rate, thus it is necessary to use special methods to increase their germination [8]. Clover plants develop well on slightly acid soils, while alfalfa prefers neutral soils, so for sowing of the second crop alfalfa seeds were mixed with zeolite-containing clay alanite.
