Adaptación de tres híbridos de tomate hortícola (Lycopersicum esculentum) bajo cubierta plástica

Abstract

The research focuses on the behavior of three horticultural tomato hybrids (Lycopersicum esculentum) under plastic cover. A completely randomized block experimental design (DBCA) was used with 3 treatments and a commercial control and 4 repetitions. Several variables were evaluated, such as survival percentage, plant height, stem diameter, number of days to flowering, number of days to fruiting, number of days to harvest, number of fruits, distance between clusters, equatorial diameter. , polar diameter and fruit weight. For the statistical analysis of the data, the SPSS Statistics program was used and tests such as Scheffe were applied with a significance of 0.05; Homogeneity of variances with a confidence level of 95%. Showing that the three horticultural tomato hybrids successfully adapted under plastic cover in the Huachi Grande parish, Ambato canton, Tungurahua province. Where it was observed that the H1-Arsin Hybrid showed outstanding results in the variables studied during the investigation, as the third best in survival with 94.28%, greater stem diameter at 75 days with 1.41 cm, fewer days of flowering with 42.55 days, fewer days of fruiting with 57.70 days, greater polar diameter with 6.26 cm and higher yield (20,100 kg/ha), the shape of the fruit was round, which indicates a favorable fruit production in this variety and adapted to the environmental conditions of the Huachi Grande parish, which makes it the most promising option in the study.
