Efecto de la fertilización orgánica e inorgánica sobre el crecimiento de tomate (solanum lycopersicum) en ambientes protegidos

Abstract

The tomato (Solanum lycopersicum) is one of the vegetables with the highest production in the world, to maintain its yields it is necessary improve fertilization to soil, so it is necessary that fertilizers supply the nutrients required by the plants, for this reason the effect of different treatments of organic and inorganic fertilization on the growth of tomato plants was evaluated, for this a research was conducted at greenhouse level, a completely randomized experiment was carried out, where the effect of 5 treatments was evaluated: (T0) control, (T1) inorganic fertilization, (T2) compost, (T3) vermicompost, (T4) compost + vermicompost, which were replicated 5 times for 25 experimental units. During the crop cycle, biometric variables were evaluated: plant height, number of leaves, stem diameter and changes in edaphic variables: organic matter, phosphorus, potassium, calcium, magnesium, electrical conductivity and pH. The statistical analysis was carried out applying a variance analysis and DGC grouping with a probability value p <0.05, using the Infostat software. The results show that the organic treatments (T2 and T3) promoted the vegetative development to find significantly higher values <0.05) of plant height, number of leaves and stem diameter compared to the control (T0) and fertilization inorganic (IT) The greater development of the plant was due to the contribution of organic matter of vermicompost which increased the availability of nutrients. The organic fertilizers evaluated did not represent any risk of salinization due to no increase in pH and EC.
