Emergence and growth of lettuce (Lactuca sativa L.) submitted to organic substrates
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 2
Abstract
Organic agriculture stands out as a mode of production consisting of a sustainable system. One of the challenges of this method of cultivation is the production of sufficient quality food in sufficient quantities without compromising the environment. The objective of this study was to analyze the effect of organic substrates on germination and initial lettuce growth. The experiment was conducted in a completely randomized design with four treatments (substrates) and two replicates. The substrates were tested: Sibipiruna compound, commercial substrate, Sibipiruna compound with slurry and commercial slurry substrate. The manure was obtained exclusively from the decomposition of vegetables. The effect of the substrates was evaluated by percentage of germination, fresh mass, dry mass and radicular length. It was possible to consider that there was a significant difference between treatments. The seeds, when germinated in substrate of Sibipiruna with slurry, presented higher dry mass and radicle length. Regarding the fresh mass, the values obtained were higher when the slurry was added to both substrates. The slurry obtained from the decomposition of plants increased the germination and the initial growth of the seedlings.
