Summary. Within three growing seasons the effect of processing spring rape variety Galant in phase buonitalia-the beginning by flowering microfertilizers on its productivity, performance patterns yield, grain quality was studied. The researches were carried out on sod-medium podzolic middle-loamy soil. On the average for 2007-2009 is established that the variants of treatment of crops by mineral fertilizers (manganese sulfate, cobalt sulphate, zinc sulfate, copper sulfate, boric acid, mixture of the studied compounds) provided a substantial increase in yields of rape seeds on 0,06...0,07 t-ha in comparison with variant without processing -1,12 t-ha. This effect is connected with the formation of bigger number of pods and seeds on a plant. Studied variants contributed to the increase in the number of pods per plant on 3...7 pcs., in comparison with the variant with spraying by water(control)-40 pcs. While applying microfertilizers their number of seeds significantly increased on 34...47 pcs., in comparison with control (534 pcs.) when NSR05-10 pcs. Studied variants contributed to increase of fat accumulation in the seeds and the gross harvest of oil. On the average in 2007 – 2008 it was showed increasing mass fraction of fat content in rape seeds: with use of copper sulphate – on 1,8%, zinc sulfate – on 2,6%, in comparison with control variant (39,0%). The highest gross harvest of rapeseed oil – 436 and 446 kg-ha revealed while spraying of crops by sulfate zinc and sulfate copper (in control – 393 kg-ha). In variants with application of manganese sulfate and boric acid, this parameter increased on 13 kg-ha (LSD05 – 13 kg-ha).
