Abstract
Introducción: La tasa de drenaje es un factor
importante en la producción hidropónica. Objetivo:
evaluar el efecto de dos tasas de drenaje sobre el
rendimiento y la calidad de pepino (cv. Modan) de
invernadero en las épocas seca y lluviosa. Métodos:
Utilizamos “fertirrigación” y fibra de coco como sustrato.
Resultados: En todas las categorías de calidad, no hubo
diferencias entre dosis de riego para el número de frutos
por m2
, peso de frutos y rendimiento; mientras que el
porcentaje de sólidos solubles totales fue mayor al 10% de
riego. Los pepinos de época lluviosa tuvieron más frutos
totales por m2; mayor peso de frutos comerciales; y mejor
rendimiento total, de segunda y tercera calidad.
Conclusión: En estas condiciones, una tasa de riego del
10% ahorrará agua y nutrientes, y aumentará la
rentabilidad del cultivo.
Introduction: Drainage rate is an important factor in hydroponic production. Objective: to evaluate the effect of two drainage rates on the yield and quality of cucumber (cv. Modan) under greenhouse conditions in the dry and rainy seasons. Methods: We used fertigation and coconut fiber as substrate. Results: In all quality categories, there were no statistically significant differences between irrigation rates for the number of fruits per m2 , fruit weight and yield; while the percentage of total soluble solids was higher at 10% irrigation. The rainy season cucumbers had more total fruits per m2 ; commercial fruit weight; and total, second and third quality yield. Conclusion: For this conditions, a 10% irrigation rate will save water and nutrients, and increase crop profitability.
