The most common crop used to produce biofuels is rapeseed. However, production experience has shown that this culture is quite demanding about the abiotic factors of vegetation and the resource component of cultivation technology. There is no such disadvantage in a culture such as radish oil. Radish oilseed is an annual herbaceous plant of the cruciferous family, cold-resistant, shade-tolerant and productive, unpretentious to the soil. Seeds of radish oil contain up to 48-50% of oil. An important positive quality of oil radish is the resistance to cracking pods, so that harvesting can be carried out at full maturity.

Radish has many advantages: high nutrition, ease of cultivation, high seed multiplication, high yields of green mass, which is nutritionally close to alfalfa.  It is noted that it has a positive effect on increasing the milk yield of cows, increasing the fat content in milk, which is why it can be saved on highly concentrated feeds.

The article reflects the results of studying the effect of complex water-soluble fertilizers on the formation of seed yield and its quality. The research system included the consecutive three times use of fertilizers balanced in both macro and microelements of different composition, meeting the characteristics of plant growth processes, the expediency of applying different intensity of additional oil radish feedings was established.

The features of the influence of different intensity of fertilizing on the individual structure of the seed productivity of plants on the main indicators that are decisive in the formation of seed output per unit area are determined. Productivity indicators have been established in accordance with the studied structure, which are most closely related to the use of complex fertilizers.

The increase in seed yield with a consistent increase in the number of dressings from one to three was evaluated and the various fertilizer formats were evaluated, depending on the levels of productivity obtained.

The features of the formation of the quality of radish oilseed seeds were determined depending on the application options for fertilizers and a general conclusion was drawn about the efficiency of complex using Folikea fertilizers to improve the technological quality of radish oilseed seeds.

Key words: oilseed radish, complex water-soluble fertilizers, fertilizing, yield, seed quality.
