Produção de morangos sob sistema semi-hidropônico em ambiente protegido

Abstract

The strawberries production in semi-hydroponic system using plastic bottles is a simple and sustainable alternative to ensure a good productivity without agricultural pesticides use, ensuring a product with better quality. In order to evaluate the strawberries production below semi-hydroponic system in protect environment, an experimente was carried out in the greenhouse of Universidade Federal do Pampa – Campus Alegrete, using the varieties Oso Grande, Camino Real and Aromas, with five substrates (carbonized rice husk, pine sawdust, earthworm humus, coconut husk fiber and vermiculite), with six repetitions each. The irrigation was fullfilled weekly, intercalating nutritive solution and water. The only strawberry variety that showed good adaptability to semi-hydroponic system was Aromas, presenting better results with interleaved irrigation between nutritive solution and water. In this study, the earthworm humus substrate was the recommended to the production of Aromas strawberry variety, in semi-hydroponic system in a greenhouse with plastic bottles, because resulted in better results in all variables analyzed. So, it is possible to produce strawberries in plastic bottles in the greenhouse, thus setting an economical, profitable and sustainable system.
