Vegetable grafting is most common in European and Asian countries where crop rotation is no longer an option and available land is under intense use. Grafting is an alternative approach to reduce crop damage resulting from soilborne pathogens and increase plant abiotic stress tolerance, which increases crop production. We discuss and outline four grafting methods that are available for vegetable production in cucurbits: tongue approach grafting, hole insertion grafting, one cotyledon grafting, and side grafting.

Data collected on 181 fields from 1998 to 2000 were analyzed for associations among cultural practices in table beet (Beta vulgaris) and levels of decay in the harvested beet roots. Increased risk of decay was associated with short rotations between beet crops, certain crop rotations in the four years before beets, the frequency of row cultivation, and narrow row spacing. Shielding during cultivation was associated with increased risk of decay, but the effect may be an indirect one. Decay levels were not associated with beet variety, the use of manure or preplant fertilizer. Decay did increase with higher rates of nitrogen side dressing. Mean decay differed significantly among growers, and could be explained in part by the set of cultural practices used by a grower. The results suggest that the risk of decay is determined by interacting biological and cultural factors. Manipulation of cultural practices and cropping sequence may be useful in managing levels of beet decay.

An interdisciplinary approach had been developed to examine the production, economic, and marketing feasibility of new crops. The methodology requires the determination of yield potential and product quality, construction of production budgets, and completion of marketing window analyses. Potential for integration of new crops into the existing farm enterprise is assessed using linear programing techniques that consider labor and equipment constraints, crop rotations and best management practices. Risk analyses consider yield, production costs, and price of both new and traditional crops. By using this method, broccoli has been identified as a potential new crop for eastern Virginia, with labor requirements and slush ice availability being the major constraints to integration into vegetable production in this area.
