Three experiments were carried out to evaluate the applicability of the intensive management system to barley production in Quebec. In the first experiment, the effects of three levels of nitrogen fertilizer and ethephon (Cerone) on the performance of cultivars were tested. The aim of the second experiment was to test the effects of fungicide application and row width. In the third experiment, conventional and intensive management techniques were tested on three soil types. / High levels of nitrogen increased the grain protein content and thus improved the feed quality of spring barley. Application of ethephon reduced plant height but also reduced the number of grains per head. A fungicide by row width interaction resulted in a reduced seed size and weight in the narrow rows. The effects of intensive management on yield were inconsistent and were influenced to a large extent by the prevailing weather and soil conditions.
