Avaliação de diferentes substratos orgânicos na produção de mudas de cucurbitáceas.

Abstract

The íbmily Cucurbitaceae is divided unto 2 süb-families: Zanonioideae and Cucurbitoideae - and comorises about 1 18 genera and 825 species. Approximately 26 species of Cucurbitaceae are cultivated as vegetables in various regions of the world. O experiment aimed to evaluate the efnciency of different organic substratos on the production of seedlings of pumpkin and watermelon. The experiments were performed in the laboratory of the Universidade Federal de Campina Grande, UFCG, Campus of Pombal. The work was conducted from December 2008 to February 2009. Were evaluated the work of pumpkin: number of leaves, plant height, diameter of the neck, fresh weight of shoot, âesh weight of roots, total fresh weight, dry weight of shoot, dry mass of roots, total dry mass and stability the turf according to the following substrates. Were evaluation in watemlelon plant height, number of leaves, diameter of the neck, dry mass of shoots, roots and all. In the case of pumpkin were used: Plantmax, sheep manure + soil, clay+ sheep manure, caule manure + soil, caule manure + day, organic compost + soil, day + organic compound. Were used for watermelon: Plantmax, caule manure + soir + band, manure + sand + day, soil + caule mamute, caule mamute + day, sheep manure + soil + sand, sheep manure + day + sand + sheep manure soil, sheep manure + day. For most varíables the Plantmax got the best results to crops of pumpkin and Watermelon, however the altemative substrates can be successfülly used in the production of seedlings.
