THE EFFECTS OF 2-CHLORO-6 (TRICHLOROMETHYL)-PYRIDINE (’N-SERVE’) AND N FERTILIZERS ON PRODUCTIVITY AND QUALITY OF CANADIAN OILSEED RAPE

’N-Serve’ has been shown to reduce losses of applied N-fertilizer and thereby increase fertilizer N-utilization by plants. This study was undertaken to test the effects of ’N-Serve’ on fertilizer N efficiency in oilseed rape production and quality. Field experiments were conducted on two chernozemic soils over 4 yr in Manitoba. The oilseed rape cultivars Tower (Brassica napus L.) and Torch (B. campestris) were used in the study. Spring and fall...
