Abstract

ABSTRACT Research was conducted to evaluate the use of plastic mulches in the production of cucumber under micro-irrigation in tropical conditions. Clear (C) plastic mulch installed on beds increased the fruit number and the yield of cucumber (Cucumis sativus L. cv. Fanci Pack) in comparison to unmulched (U) soil, during 1992–1993. White (W) and black (B) plastic mulches showed a moderated effect. Marketable yields of 63.3,46.2,44.8 and 21.6 t/ha were achieved under C, W, B and U treatments respectively (P<0.05). The plastic mulches reduced the number of days to flowering and to first harvest and increased the fruit number. It is concluded that clear plastic mulch is more adequate for tropical conditions than black or white plastic mulches.
