There was estimated the effect of Nitrogen fertilizer and bio-preparation Rhyzoagrin made on the basis of Agrobacterium radiobacter strain on the spring wheat grain yield. There have been carried out 6 experiments were conducted in 4 regions of the nonchernozem belt of Russia. Wheat was grown in the soddy-podzolic loamy sand soils in the process conventional in the regions using P60K60 and N60P60K60. The fertilizers were applied for secondary tillage. There has been discovered the close positive dependence (r = 0.77-0.90) of the grain inoculation efficiency with a biological preparation on the soil medium reaction and the hydrothermal coefficient (HTC) value during the vegetation period. The minimal increase of the spring wheat grain yield (1.2-1.9 dt/ha) from the use of the bio-preparation was obtained at the HTC value of 1.3. Its influence was more effective during the stressful weather conditions of the vegetation period. With an acid reaction of soil medium (pHKCl less than 4.8) a positive effect from the use of Rhyzoagrin was actually absent When the soil medium reaction was close to neutral (pHKCl 6.0-6.7) and the HTC was 1.64-1.82 the increase of spring wheat grain yield from Rhyzoagrin by using PK fertilizers reached 3.0-5.5 dt/ha. The grain inoculation effect during fertilizing wheat with N30 did not depend on the meteorological conditions during the growing season.
