Abstract
At nine locations, selected throughout the Brown, Dark Brown and Black Soil Zones, wheat and barley were grown on summerfallow (9 locations), cereal (8 locations) and oilseed stubble (6 locations). In total, 46 experimental plots with barley or wheat as crop were established. Soil analyses were carried out and for all locations and P fertilizer was recommended by soil testing guidelines. Wheat and barley were: (1) inoculated with a phosphorus solubilizing fungi, PB50, at. time of seeding, (2) received P fertilizer at recommended rate, or (3) remained untreated. At four sites the rhizosphere soil of cereal inoculated with PB50 and untreated plants were sampled between 6 and 8 weeks after planting and the number of P solubilizing fungi determined. All rhizosphere soil of inoculated and uninoculated plants contained P solubilizing fungi. Total grain plus straw yield for wheat varied from between 1316 kg/ha in the Brown Soil Zone to 6597 kg/ha in the Black Soil Zone. Total yield for barley varied between 1217 kg/ha and 6472 kg/ha. Corresponding grain yield varied between 332 and 2676 kg/ha for wheat and between 266 and 3069 kg/ha for barley. P fertilization significantly increased total yield of wheat or barley at 7 sites (15 % of the time) of all sites tested. PB50 significantly reduced total yield of wheat or barley at three sites (7 % of the time), and increased total yield of wheat at one site (2 %). P fertilization increased grain yield by wheat or barley at 7 sites (13 % of the time), whereas PB50 reduced grain yield for barley and wheat at one site (4 % of the time). Although all sites showed inadequate available P levels in the spring as determined by soil test analysis, at 85 % of the time wheat and barley did not respond to P fertilization. This can partially be explained by the poor growth conditions at some sites or to the inadequacy of the method used to determine plant available P.
