For determination efficiency of outside roots fertilizers in spring wheat, spring wheat 'Vinjet' have been sown on 30 April 2007 by sowing rate 600 germinating grains per 1 square m, that develop 232 kg haE-1 of sowing rate. Before wheat sowing 600 kg haE-1 of the complex fertilizers NPK 16:16:16 had been worked into soil, by it 96 kg haE-1 of nutrients NPK had been worked also. At the end of shooting into culms 40 kg ha E-1 of additional fertilizer nitrogen had been worked into soil in form of ammonia nitrates. Outside root fertilizers applying two times at the end of growing in bushes and shooting into culms, at the beginning of shooting into ear, exclude Hydro Plus that has been applied one time at the end of growing in bushes. Conclusions: (1) in 2007 agro-meteorological conditions for spring wheat all nutrients was accessible insufficient amount even for soil existed resources and additional use of trace elements via leaves not give essential increase of grain yield. The mathematical processing of data argues that difference of yield between variants was not essential (P = 0.9468 is greater than 0.05); (2) in all fertilizing variants obtained grains with content of protein - 14.3-14.8%; content of gluten 28.3029.6% and 39.9-41.4 g of 1000 kernel weight correspond to requirements of food grains; (3) the mass distribution of diseases and pests have been not observed during wheat vegetation.
