dc.description.abstractStudies to evaluate stubble management, weed control, and fertility treatments applied in combination in a continuous spring wheat (Triticum aestivum L.) rotation were conducted over a seven year period (1983-89) at Scott, Lashburn and Loon Lake and over a four year period (1983-86) at Kindersley and Mervin. Leaving stubble standing overwinter at either a normal swathing height or with strips of taller stubble as snow-traps gave yields equal to or significantly greater than fall tillage. Use of herbicides for control of broad-leaved and grassy weeds generally increased yield as did application of nitrogen and phosphate fertilizers. Yields were increased from 910 to 1970 at Scott; 1300 to 2450 at Lashburn; 940 to 1600 at Loon Lake; 1150 to 2420 at Kindersley; and from 1920 to 2920 at Mervin where herbicides and fertilizers were applied in combination with tall stubble compared with no herbicide or fertilizer application. The occurrence and nature of interactions between factors suggest a need to conduct more studies to evaluate interactions of cropping system components. In developing sustainable crop production systems it is likely that improved efficiencies will arise from development and manipulation of entire cropping systems rather than individual components.en_US
