Experimental plots were overlaid on commercial fields of broccoli (Brassica oleraceae L. var. Italica) and cauliflower (Brassica oleraceae L. var. botrytis L.) to evaluate legume species as interseedings in vegetable production. White clover (Trifolium repens L.), red clover (T. pratense L.), yellow sweet clover (Melilotus officinalis L.), hairy vetch (Vicia villosa Roth.) and crimson clover (T. incarnatum L.) were seeded 4-5 weeks after an early planting of broccoli and a late planting of cauliflower. Crop yields, forage biomass, weed biomass and percent fall ground cover were recorded. / A dry year coupled with difficulties in applying the treatments resulted in low forage biomass. Hairy vetch yielded the most within the early broccoli planting system. High rainfall the next year resulted in high biomass yields. Over the two year study, hairy vetch and crimson clover emerged as the two most productive species. Significant effects on fall weed biomass were observed with broccoli in the second year of the study, where interseeded plots reduced weed populations by at least 66%. No evidence was seen of weed suppression by interseedings prior to harvest. Crop yields were not affected by interseedings. All interseeded treatments provided the minimum of 30% ground cover required to help reduce erosion.

Home-ownership is a source of security, sense of belonging and saving accumulation. In the City of Montreal only a quarter of the population own their homes. Despite the fact that the majority of renters wish to become owners, only a small fraction can afford new products of the home-building industry. In this thesis the author proposes to the industry a strategy for cost reduction: uncompleted condominiums, that are the least finished dwelling units legally allowed for living. The proposed design is analyzed from the legal, social, technical and economic points of view. The research is founded on a review of the literature, a market survey and three simulations. It was found that the proposed product might be 26-29% less expensive, than investigated examples, and could be appreciated by childless households.
