CARACTERÍSTICAS DEL SUSTRATO Y CALIDAD DE PLANTINES DE LECHUGA (Lactuca sativa L.) SEGÚN DOSIS DE LOMBRICOMPUESTO

Abstract: RESUMENEl uso de sustrato con lombricompuesto favorece el crecimiento en cultivos hortícolas, siendo importante conocer sus propiedades para dosificar la cantidad adecuada. Este trabajo tuvo como objetivo analizar las modificaciones producidas en un sustrato según la dosis de lombricompuesto adicionado y evaluar el efecto de las mezclas sobre la calidad del plantín de lechuga. El ensayo se realizó en un invernadero en Luján, Argentina (34°36' S, 59°04' W). Se sembró lechuga mantecosa cv. Tizona, utilizando sus… Show more

“…Bachman and Metzger (2008) have stated that additional vermicompost in the growth medium very little affected the growth of pepper seedlings. In a study conducted to analyze substrate changes according to vermicompost doses and evaluate the effect of the mixtures on lettuce seedling quality, the substrates with different amounts of vermicompost added and a commercial mix of peat and perlite had been used (Tombion et al, 2016). As a result, the addition of vermicompost resulted in a linear increase in pH, electrical conductivity, nutrient level, bulk density and total porosity of the substrate and a 20% increase was determined in seedling size.…”

“…Ievinsh (2011) determined that the vermicompost substitution inhibited the seed germination and seedling growth of several vegetable crops with an almost linear decrease of growth with increasing concentration of vermicompost in the substrate. By Tombion et al (2016), the effect of substrates with different amounts of vermicompost (0, 20, 40%) added and a commercial mix of peat and perlite of the mixture on lettuce seedling quality has been assessed. As result, it was determined that the mixture containing 40% vermicompost gave the lowest leaf number, and the fresh and dry weight of leaf and root decreased (even lower than the control), while the seedling quality in which mix containing 20% vermicompost is higher than others.…”
