Evaluación a nivel de vivero del desarrollo morfológico del pachaco (Schizolobium parahybum) con el uso de tres sustratos, en la provincia Esmeraldas.

Abstract

The aim of this research was to evaluate the morphological development of pachaco (Schizolobium parahybum) at nursery level with the use of three substrates in Esmeraldas Province. The growing interest in establishing fast-growing forest plantations has increased the high production in nurseries, therefore, this implies that nurserymen should develop quality species in the shortest possible time. In this research, a complete randomized design with 4 treatments and 3 replications was carried out, being treatment 1 the control (black soil), treatment 2 (Giberacid Jiffy), treatment 3 (Peat LM-18) and treatment 4 homemade (25% sugarcane bagasse, 25% rice husk and 50% black soil). The quality of the seedlings, the percentage of germination at 15 days, the percentage of mortality and a cost analysis to determine the most suitable substrate at the nursery level were established. According to Dickson's formula, treatment 4 (homemade) was the best quality, for the percentage of mortality it was observed that treatment 2 (Jiffy) was 86.57%, surpassing the other treatments, for the cost analysis the most convenient treatment was treatment 4 (homemade) with $255.55. To conclude, the treatment 4 obtained better results in economic and quality, however, the homemade treatment should be carried out with a cleaning process.
