Description
An extensive research project was initiated in 1992 to develop a dryland seed production system for creeping bentgrass (Agrostis stolonifera L.) in western Canada. Two objectives involved determining the appropriate renovation method and spring nitrogen timing and rate to maximize seed yield. Renovation experiments included scalping, mowing, aeration, tillage, burning and chemical and mechanical gapping and spring N fertilization experiments included at 0, 50, 100, and 150 kg N ha-1 at two dates. Scalping (removal of stubble and growth to 1.25 cm) showed the greatest potential to maintain seed yields. Timing of renovation was also important with early (after harvest) treatments superior as they allowed an adequate regrowth period prior to winter. Spring nitrogen applications of greater than 50 kg ha-1 did not show increased seed yields. Dryland seed production is possible in the higher rainfall areas of western Canada with yields ranging from 50 to 500 kg ha-1, but attention to recommended management practices is essential given the short growing season.
