| dc.description.abstract | Four locations in the Brown (Leader, Sceptre, Kindersley, and Gull Lake), two in the Dark Brown (Regina and Outlook (irrigated)), five in the Black (Blaine Lake, Dubuc, Glenavon, Langbank, and Star City), and two in the Dark Gray soil zones (Nipawin and Porcupine Plain) were selected in the spring of 1990. Selection of the locations was based upon the available P status in the soil. With a few exceptions, all locations required P fertilization. At each location, the experiment was carried out on fields that were either on summerfallow, cereal stubble or oilseed stubble, all in close vicinity to one another. The experiment was laid out as a randomized complete block design with the following treatments 1) Control, 2) PB50 only, 3) 11.2 kg/ha of P2O5, 4) PB50 + 11.2 kg/ha P2O5, 5) 22.4 kg/l1a of P2O5 and, 6) PB50 + 22.4 kg/ha P2O5, replicated four times. Nitrogen and in some cases P and S was applied at blanket rates when necessary. At all sites Katepwa spring wheat was used as the test crop. Crop yields (grain and grain+ straw) were determined and fluctuated widely among the 13 locations due to the variable precipitation received in 1990. At one site, a significant (P <0.05) P fertilizer response on grain yield was observed. Whereas significant responses did occur at other sites, it was not directly related to P fertilizer and/or PB50. At most of the sites, however, no P fertilizer and/or PB50 response was observed. The concentration of P in the tissue, sampled at the Feekes 2 to 3 stage, was found to be not significantly different between the various treatments at most of the sites tested. If a significant difference was observed, the P fertilizer application caused the increase in P concentration.With the exception of two sites, the average amount of kg P/ha removed from the field through the grain was less than the total amount of the full rate of applied P and at some sites, half or less P was removed. | en_US |
