Evaluación de tres colores de acolchado plástico para la producción de fresa (Fragaria x Ananassa), variedad Albión, en la parroquia Montalvo, provincia de Tungurahua

Abstract

The strawberry (Fragaria x ananassa) is very important for its high level of demand and production in different parts of the world, the fruit considered delight for magnificence, also has high levels of vitamins and minerals, so it is necessary to carry out research on new strategies that allow to increase the yield of the crop. Plastic padding stands out as one of the components that has the most influence on strawberry production, this thanks to the fact that it contributes to various benefits in cultivation. In this sense, in the present research the agronomic behavior of the strawberry crop with three colors of plastic padding was evaluated. In this way, different colors were used (black, white and silver) and compared with each other, different parameters were evaluated (plant height, weed population, fruit size, crop yield, soil temperature and attack of pests and diseases). In the plant height, a significant effect was observed from 90 and 120 days, demonstrating that black plastic mulch is the most recommended. For weed population there were significant differences throughout the evaluation period, with black plastic mulch demonstrating the best effect compared to white and silver. As for the size of the fruit, the polar and equatorial diameter was measured and in these two no significant differences were observed. In terms of performance, no significant effect was observed between treatments, but there were numerical differences, showing that the black color had a greater advantage with 5699 kg /ha compared to the white and silver plastic padding with 4793 kg/ha and 5002 kg/ha respectively. Both at 30, 60, 90 and 120 days the temperature varied and it was evident that black plastic always presented the highest temperature values in relation to white and silver plastics. The pests and diseases that were observed in the research were Spodoptera frugiperda, Oidium fragariae and Botrytis cinérea.
