Peculiarities of winter rape crop formation at spring sowing
The results of long-standing investigations of the peculiarities of winter rape crop formation at spring sowing are presented in the article. It is found that the productivity of winter rape for 2–3 hay cutting achieves 594–898 c/ha of green mass, 65–107 c/ha of dry matter depending on the terms of the first hay cutting, a height of plant cutting, and favorable conditions. Regulating the harvesting terms of the first hay cutting of rape, it is possible to provide the regular reception of green feed for animals from the end of June to the end of October.

Polymorphism of liquid fractions of egg white
The presence of two alleles (A and B) has been found in free loci in all studied hybrids. Frequencies of occurence of alleles were different, so as in some cases the frequency of A-allele was higher in locus I (Roso SL 2000 and Roso 93 hybrids) and in loci II and III (Albo hybrid). In other cases, on the contrary B-allele was encountered more often in loci II and III (Roso SL 2000 and Roso 93 hybrids) and locus I (Albo hybrid). All examined groups were in conditions of genetic equilibrium. The highest genetic similarity factor (0.99) of two hybrids – Roso SL 2000 and Roso 93 – proves their common origin.

Prediction of the indices of resources consumption and production intensification in plant growing
Resources consumption is estimated depending on the level of the production intensifiation. Its regularities are established and methodical approaches to solving the resource-saving problem are outlined. It is shown that the expenses of production resources per each unit growth of crop yield are 0.6 – 0.9 of unit growth. This points to the intensification efficiency as a resource-saving factor and is caused by the fact that many works are being carried out irrespective of the crop yield level.
