Evaluation of three dose of chelated fertilizer in three tomato hybrids (mill lycopersicum esculentum)

Abstract

The research was carried out in the summer season of 2015, in a greenhouse protected environment, with a wooden structure completely covered by mesh on the sides and plasticized raffia on the roof, in the northern part of the Guayas province, located in km 3 of the Balzar - El Perimetral junction, on the land owned by Mr. Cristo?bal Antonio Arana Herna?ndez. In this trial three hybrids of tomatoes, Pietro F51, Fortuna and Dominique were studied with three doses of chelated fertilizer, 4 and 2 l / ha, and a third (control) without fertilizer application. The following objectives were set for the experiment a) Study the agronomic behavior of three tomato genotypes in a protected environment, b) Investigate the optimal dose of chelated fertilizer in tomato production with cover, c) Determine the treatment with the best economic response in The conditions tested. The completely randomized block design with 3 x 3 factorial arrangement with three repetitions was used. For the statistical analysis, the variance analysis technique was applied, when the differences in this were significant, the comparison of treatment means was performed using the Tukey test at a 5% probability. The treatments with doses of 2 and 4 l / ha of chelated fertilizer showed the highest average height of the plant. The variable number of leaves, recorded the largest amount in treatment 3.
