Evaluación de dos compensadores de horas frio en tubérculo de papa (Solanum tuberosum) variedad única pera en el cantón Mocha

Abstract

The present investigation was developed in the property of Mr. Vicente Palacios, located in Canton Mocha, under a plastic cover of (6mx2m), which generates an average ambient temperature of 26 degrees Celsius, in the potato crop (Solanum tuberosum) Variety Unique Pear, for which tubers harvested at the stage of physiological maturity were used and 10 kg bags were used for each treatment. The products and doses used were; Dormex 10ml- 30ml - 50ml; Urea 10 gr. - 20gr. - 30 gr. The information was recorded 30 days after the application of the treatments. The results were taken from 10 tubers at random by repetition; the following were evaluated: number of sprout, sprout diameter, sprout length, days to sprouting, tuber weight loss. The results obtained were: the Q2D1 treatment showed better results in all the study variables such as number, diameter and length of shoots, which began to sprout 27 days after the experiment was installed. With the results obtained, it was possible to conclude that the use of a cold-hours compensator accelerates the sprouting process, obtaining seed tubers in a short time and with good characteristics.
