THE EFFECT OF SEEDBED TREATMENT BY THE PROTECTING PREPARATIONS AND MINERAL FERTILIZERS ON SEED QUALITY

Abstract

Soil fertility decrease, economic and organizational factors reduce the valuable qualities of the varieties, and therefore the preventive measures that prevent deterioration of the variety are of great importance. Seedbed treatment, such as disinfection of seeds with the preparations that have a healing effect from various diseases, soil pests and air-thermal treatment of seeds, application of mineral fertilizers are important measures necessary for effective seed production. Long-term studies conducted on experimental and industrial plots of the Samara RIA have established that seed disinfection with the preparations of systemic action ‘ScenicCombi’, ‘Lamador KS’, ‘Ranazol Ultra KS’ is the most effective. There has been estimated the effect of spring solar heating of seeds by warm atmospheric air, promoting their awakening, exit from ‘secondary dormancy’ and germination increase. There has been noted a positive effect of the full fertilizer on the sowing and yielding qualities of the seeds. There have been determined the optimal doses of fertilizers N30P30K30, N45P45K45 for seed production of winter wheat, spring wheat and barley with the best yielding properties (on 6.2–7.4% in comparison with the control).
