Use of Plastic Protections in Field Grown Melon (Cucumis melo L. var. reticulatus) for the Optimization of the Production Process

Abstract

This in-farm research study was aimed at evaluating new strategies in the use of plastic protections in field grown melon, in order to expand the production period and reduce costs. Experiments were set up in 2010 and repeated in 2011 in Central Italy, on an inland region with temperate climate. We evaluated: i) the use of high tunnels for two growing cycles per year, i.e. for very early and very late production (target transplanting in late winter and mid summer, respectively), for either one year or two consecutive years, and the use of grafted plants in the second year as an alternative to normal plants to prevent soil born diseases; ii) the use of ethylene-vinyl-acetate film low tunnels alone or combined with non-woven floating rowcovers for transplanting in early spring; iii) the use of non-woven low tunnels for transplanting in mid spring; iv) the use of biodegradable and conventional poly-ethylene ground mulch films, both in the presence of non-woven low-tunnel. As far as the non-woven cover is concerned, we adopted the strategy of removing it in delay, with respect to usual practices, i.e. ten days after the onset of first pistillate flowers. This was based on the evidence that covers hamper honeybee circulation, which may be exploited on a farm-scale to delay pollination until an adequate number of pistillate flowers set, in order to shorten scaled fruit ripening and harvest. Our results demonstrate that high tunnels may be used for at least four consecutive melon growing cycles (early and late productions for two years) with good off-season yields and no appreciable drawbacks in terms of disease scale-up, irrespective of the use of normal or grafted plants. The non-woven low tunnel was effective in hampering honeybee circulation and its delayed removal allowed to half the harvest period, obtain more uniform fruit size and increase labour productivity of harvest. This had positive implications on the management of irrigation and chemical disease control closed to harvest period, and on the management of harvest and post-harvest operation schedules, including fruit processing, packaging and delivery to markets. In the presence of non-woven low tunnel, the biodegradable mulch did not differ substantially from other mulches for effects on harvest dates, yield and weed control, so that its use can be convenient provided that its cost is not higher than that of traditional poly-ethylene films and of their wasting.
