Evaluación de tres tipos de ácidos húmicos mediante fertiriego en el rendimiento del cultivo de cebolla (Allium cepa l.) var. burguesa en la parroquia Yaruquíes

Abstract

The aim of this research was to evaluate three types of humic acids by fertigation on the yield of onion (Allium cepa L.) var. Burguesa in the Yaruquíes parish. The methodology implemented was a randomized complete block design (RCBD) with three replications. The treatments under study were three types of humic acids plus a control: T1 (HUMEGA), T2 (HYDRA HUME), T3 (HUMISOL) and T4 (WATER). Agronomic performance at 30, 60 and 90 days after transplanting was evaluated for percent stand, plant height, number of leaves per plant, days to harvest and bulb radius. In addition, total yield was evaluated in kg.ha-1 and categorized according to caliper. Finally, the economic analysis was carried out using the benefit-cost ratio. The results obtained showed that, through the application of HYDRA HUME, 98.58% of plants set, bulbs of greater radius with 66.43 mm and a total yield with 37 533.11 kg.ha-1 were obtained, with a second category yield of 23 828.65 kg.ha-1. Meanwhile, the greatest plant height and the greatest number of leaves were achieved with the application of HUMISOL. Finally, the best B/C ratio was obtained with the application of HYDRA HUME, which was 1.59. It is concluded that the best humic acid for fertigation of the onion crop is HYDRA HUME, because the best yields in terms of production and benefit-cost ratio were obtained.
