Evaluación del rendimiento del cultivo de brócoli (Brassica oleracea l) con dos tipos de agua y tres dosis de abono orgánico en la Estación Experimental Tunshi-Espoch

Abstract

Una This research was focused on evaluating broccoli (Brassica oleracea L.) crop yield with two types of water and three doses of organic fertilizer at Tunshi ESPOCH experimental station. A randomized complete block design was used in a split-plot arrangement with six treatments and three replicates. The treatments included two types of water (Tunshi water and treated gray water), in combination with two doses of organic material (3 t/ha, 1.5 t/ha of poultry manure) and an absolute control. Plant height, stem diameter, number of leaves at 30, 45, 60, 75, and 90 days after transplanting, root length, pellet diameter and yield were evaluated at the end of the crop cycle. The results show significant differences mainly in the dose of organic material and an interaction with the treated water, being the dose of 3 t/ha in combination with the treated water the one that shows better results in addition to a yield of 25 t/ha, with respect to water quality, a similarity between treated water and irrigation water is observed after contrasting them with the values established by TULSMA. The economic analysis showed that the dose of 3 t/ha reached the highest profit with a value of 1.35, which makes it the ideal dose to apply in the broccoli crop.
