Influencia del vermicompost y sus lixiviados sobre la germinación de hortalizas en un suelo sódico

Abstract

The objective of this work was to evaluate the influence of vermicompost and leakage on seed germination and growth of vegetable seedlings in sodium soil. The study was carried out in vegetable species: lettuce, cabbage and tomato, in total three tests were established to analyze the individual behavior of each vegetable subjected to four treatments with three repetitions. The evaluated treatments were T1 (Sodium soil. Control); T2 (Sodium soil + Vermicompost); T3 (Sodium Soil + Vermicompost Leakage); T4 (Sodium soil + Vermicompost + Vermicompost leakage). In three vegetables evaluated, treatments T2 and T4 were those that stood out with germination index values ​​that were between 112 and 172%. This trend of better response of vegetables towards T2 and T4 was maintained in the variables of total seedling weight, hypocotyl and radicle length. In this way we can conclude that, by applying vermicompost and its leakage it is possible to improve the biological response of vegetables grown in sodium soils. Vermicompost has a high MO content (43.6%), this could explain the positive response of the treatment containing this product T2. As well as the remarkable synergy of both by-products in T4. However, further studies are needed to understand in greater detail the mechanisms with which these organic compounds reduce the antagonistic effects of sodium on plant physiology.
