Evaluación de tres formas de curado de la cebolla híbrido burguesa (Allium cepa L.) para extender el tiempo de vida del bulbo

Abstract

The present work was carried out with the purpose of evaluating three ways of curing the bourgeois hybrid onion (Allium cepa L.) to extend the life of the bulb. The experiment was carried out on the property of Mr. Luis Guangasi, located in the province of Tungurahua, Canton Ambato, Izamba Parish, San Jacinto neighborhood, located 7.5 km north of the city of Ambato, at an altitude of 2740 msnm, Whose geographic coordinates are: 01 15 '12' South latitude and 78 39 '59' West longitude (Data taken with GPS). A split plot design with factorial arrangement 3 * 3 was used, with three replications, with the main plots being assigned to curing forms factor.

Statistical analyzes were performed to determine that the shortest curing time occurred when the bulbs were placed under plastic cover A2 with an average of 25 days, possibly because the higher temperature and lower humidity present in this environment resulted in a faster drying of The bulbs. The loss of moisture was greater with curing under plastic cover with a value of 31% due to the conditions of relative humidity and temperature existing under this cover which allows a better drying of the bulbs and therefore smaller postharvest losses due to the attack Of diseases.

In the variable bulb diameter no statistical variations were observed in the post-harvest process using different curing forms, but if variations are distinguished when analyzing the categories what can be explained saying that having started with bulbs of different diameter logically this difference was maintained Until the end of the experiment. Analyzed the variable diameter of the bulb neck it was established that the outdoor curing was the best for this variable with values of 10.99 mm at 5 days, 8.20 at 10 days, 4.74 mm at 15 days And 3.47 mm at 20 days. While the categories had a decrease in the diameter of the similar neck reaching a permanence from the 20 days until the end of the test.
