Summary. The results of three years of research on the effect of pre-sowing treatment of oats variety Argamak by micro-fertilizers on the yield, structure of productivity, photosynthetic activity, grain quality are presented. Researches were carried out on the turf – middle podzol loamy soil. In average in 2003-2005 it was established that all the variants of pre-sowing treatment by microfertilizers (boric acid, molybdenum acid ammonium sulfate, cobalt, manganese sulfate, zinc sulfate, potassium permanganate, liquid fertilizing-stimulating mixture, a mixture of the compounds) provided a significant increase in grain yield of oats variety Argamak on 0,27...0,41 t-ha (11...17%) in comparison with the yield in variant without seed treatment – 2,47 t-ha. Increase in yield was due to a substantial increase in the density of productive stalks – on 56...77 per-m2 (LSD05 - 18 per-m2), panicle productivity – on 0,04...0,05 g (LSD05 – 0,02 g ) and its grain number – on 0,6...1,7 pcs grain (LSD05 – 0,6 pcs). Seed pre-treatment with copper sulphate, ZhUSS-1, a mixture of salts contributed to the increase in leaf area, its influence was seen in all the years of research during all phases of vegetation. During the formation of the highest leaf area (phase of booting) the difference between the control and investigated variants in average over three years was 2,4...4,0 thousand m2-ha (8...14%). Researched treatments caused increasing the level of accumulation of bimetals in the grain within hygiene standards.
