Abstract
Growth chamber and field experiments were conducted on three low micronutrient alkaline soils from Northeastern Saskatchewan to test the efficacy of PB-50 inoculation and phosphorus (P), copper (Cu) and zinc (Zn) fertilization in relation to plant yield and nutrient uptake responses. Field experiments involving wheat (Triticum aestivum; 'Katepwa') and peas (Pisum sativum; 'Titan') showed no yield or P uptake as a result of PB-50 seed inoculation or P2O5 fertilization for three locations. Fertilization of wheat with CuSO4 and peas with ZnSO4 produced increases in seed and total plant uptake of Cu and Zn. A yield increase from 2722 kg/ha to 3682 kg/ha (40 to 54 bu/ac) as a result of Cu fertilization was observed for Katepwa wheat on Nipawin Soil (DTPA Cu = 0.1 ug/g). No other yield increases were observed for Cu or Zn fertilization on the other soils. Growth chamber experiments involving wheat (Triticum aestivum; 'Park') and navy beans (Phaselous vulgaris L.) produced results similar to field experimentation. Increased Cu uptake in wheat for CuSO4 fertilized treatments was observed for all three soils. Copper fertilization in the Nipawin soil showed a yield increase in wheat relative to control. Wheat seed inoculation with PB-50 produced no yield increases and minor nutrient uptake differences. Increased yields and Zn uptake in beans for ZnSO4 fertilized treatments was observed in all three soils. Seed inoculation of navy bean with PB-50 produced variable yield increases and nutrient uptake differences in two of three soils.
