reaches 83-95 percent to the protein of hen's egg. The content of raw protein on the
stage of budding was maximal in cultivar SL-38 (16.88%) and minimal in sample
Ustodlivy (9.31%) (Table 2.2).

Results of the experiment are evident of the positive correlation in introduced cul-
tivar SL-38 and some other samples between content of dry matter and raw protein.
Besides organic matters, the green mass of clover contains a lot of ash and dif-
ferent elements. In particular, the content of ash in studied samples varied on the
stage of budding from 9.11 to 10.72 percent. Standard cultivar Daryal had the best
index—10.72 percent.
Potassium plays an important role in the physiological processes of plant organ-
ism. It encourages formation of protein substances in plants, increase of sugar synthe-
sis in leaves and their further transportation to other organs, regulates proportion of
free and combined water in tissues, and increases hydrophilic effect of protoplasm.
Calcium is no less important for the vital functions of plants, and its lack leads to slim-
ing and rot of the root system and loss of tolerance to fungal diseases [6].
According to our data, standard cultivar Daryal contained the largest amount of
calcium and potassium—1.72 and 2.05 percent, respectively. Other samples had near-
ly the same concentration of calcium, but differed on phosphorus accumulation. Cul-
tivar SL-38 contained the largest quantity of phosphorus (1.0%), while among other
samples this index varied from 0.73 to 0.93 percent. It is known that phosphorus is a
part of nucleoproteins, and reproductive organs of plant and seed embryos are rich in
this element. Lack of phosphorus leads to slow growth, depression of fl owering, and
seed formation. According to our observation, the ratio of calcium and phosphorus
varied among different cultivars from 1.4 (SL-38, Gornaya Saniba) to 2.3 (Daryal).
