Evaluación de cinco híbridos de tomate hortícola (Lycopersicum esculentum) bajo cubierta plástica en la parroquia Izamba

Abstract

The investigation was conducted on the property of Mr. Abelardo Ronquillo, located in the Yacupamba sector, Izamba parish in the northwest of the province of Tungurahua whose geographical coordinates are: 01º 13 '00' 'South latitude and 78º 34' 59.9 '' West longitude , at the altitude of 2572 masl, taken with the Global Positioning System (GPS). The objective of the trial was to determine the hybrids of horticultural tomato (Lycopersicum esculentum) of better adaptation and production using five hybrids: Fortuna (H0), Code 60922140709 (H1), Code 61020656 (H2), Code 61020132 (H3), Code 61020119 (H4), under plastic cover in the Izamba parish. For the analysis of results, the experimental design of blocks completely randomized (DBCA) was used, with five treatments and three repetitions. The analysis of variance (ADEVA) and Tukey significance tests were performed at 5% to differentiate treatments. The economic analysis of the treatments was carried out applying the cost-benefit ratio (RBC) method and it was concluded that the Fortuna hybrid reached the highest benefit-cost ratio of 4.06, where the net benefits were 3.06 times the investment being the most profitable treatment from the economic point of view. The hybrid Fortuna was the one that produced the best results, recording the best percentage of emergence with 97.77%, longer duration of harvest (65.33 days), no green shoulders (0.00 fruits), fruit shape (flattened), greater number of fruits of the first category (24.80 fruits), better yield (8.96 kg), maintaining in the best ranges firmness of the initial fruit and 8 days of harvest with (3.97 pounds of pressure) and (1.30 pounds of pressure) respectively. The remaining hybrids in the research produced good results in terms of yield, percentage of fruits of the first and second category, firmness of the fruit, but above all in terms of the precocity in the harvest since it is what the farmers look for best.
