Abstract

The purpose of this research was to determine the performances of lettuce (Lactuca sativ L.) using low cost soilless gardens in peri-urban areas of the city of Teresina (Piaui-Brazil). In the suburbs of main cities, the introduction of gardening activities may be a sustainable tool to reduce poverty and improve food security. However, due to low access to fertile land horticultural production is constrained. The introduction of low cost hydroponic gardens may be a sustainable way to launch horticultural production in roof, terraces and courtyard. The proposed soilless system are constituted by sloped lines of plastic bottles connected together into a closed pipeline. Four experiments were conducted between June and September 2007, applying the following factorially combined treatments: 1st experiment - garden orientation (west-east vs. east-west), two nutrient solutions (namely Maceiò and La Molina) and three cultivars (“4 Estacoes”, “Elisa” and “Banchu”); 2nd experiment - two nutrient solutions (Maceiò and La Molina) and four cultivars (“Grand Rapids”, “Solaris”, “Veronica” and “Isabella”); 3rd experiment - two nutrient solutions (Maceiò and La Molina) and two cultivars (“Veronica” and “Red Comet”); 4th experiment - the garden slope (17, 22, 27%) and two cultivars (“Veronica” and “Red Comet”). The experimental design consisted of entirely randomized subdivided plots. Plant growth was measured at different phenological stages. Moreover, three times per week, N-Tester measurements were performed on young unfolded leaves. At harvest main biometric measurement were conducted. Period from sowing to harvest was particularly short (44 days), and yield reached 3,7 kg m-2.
