    Evaluación de diferentes concentraciones de fertirrigación en cultivo de nardos (Polianthes tuberosa L.) en la finca “Los Abuelos” Sayausí – Ecuador
    (Universidad de Cuenca, 2025-09-11) Loja Pacho, Teresa del Carmen; Zea Dávila, Pedro René
    The tuberose, Polianthes tuberosa L., is an ornamental plant that is propagated by means of bulbs, it is well known in the world for its fragrance and cut flower, however, its cultivation time is a limiting factor for flowering. Therefore, this research was carried out in order to evaluate different fertigation concentrations in the cultivation of tuberose. For planting, confined beds with a fertigation system were implemented. A completely randomized design (CRD) with 4 treatments and 3 replications was used. The study variables were: stem length, stem caliber, leaf length, number of flowers, percentage of chlorophyll and time of sprouting of flowers. Fertilizer application was carried out during the vegetative stage (induction, stem elongation and inflorescence development) to determine the effect on the flowering stage. The results indicated that: treatment 4 (+50% of the concentrations recommended in the literature) obtained the best averages in stem length (89 cm), stem caliber (0.7 mm), leaf length (21 cm) and 21 flowers. The time to flower bud break was better with treatment 3 (recommended concentrations in the literature), which took 67 days. With the percentage of chlorophyll, it was shown that the amount of chlorophyll between treatments is directly related to fertilization. In conclusion, the application of correct fertilizer concentrations at the right stage is a key factor to improve production, yield and crop cycles.
