Evaluación de cuatro tipos de sustratos en la producción de plántulas de la especie ornamental Celosia (Celosia Argentea) en el campus CEASA UTC 2023

This research sought a new alternative for the producers of seedlings in pylons, to reduce the loss in germination of the species, the research was conducted in the pylon of the CEASA campus of the Technical University of Cotopaxi, Latacunga canton, Eloy Alfaro parish, Salache neighborhood; with the objective of evaluating four types of substrates in the production of seedlings of the ornamental species celosia (Celosia argentea). The methodology used for this study was experimental and field with the following substrates: peat, perlite, vermiculite, coconut fiber, with a mixture of (peat 100%), (peat 50% + vermiculite 50%), (peat 50% + perlite 50%), (peat 50% + coconut fiber 50%) with a completely randomized block design (DBCA), with four treatments and five replications, obtaining 20 experimental units. The results of the study in terms of the variables, T2 (peat 50% + vermiculite 50%) was the one that occupied the A rank; in germination percentage 98.6% was obtained. 6%, seedling height at 45 days had an average of (6.34 cm), plant diameter occupied the A rank with an average of (6.4 mm), number of leaves with an average of (15.47), root length (13.6 cm), thus recommending the T2 treatment (peat 50% + vermiculite 50%) for the production of celosia seedlings (Celosia argentea), in pylons, since it presented the appropriate physical characteristics for the development of this species.
