The objectives of this research were: To determine the agronomic behavior in each of the hybrids. Validate the effect of chemical and organic fertilization on the variables to be evaluated. Establish the economic analysis of the benefit/cost ratio (B/C). The present investigation was carried out on the property of Mr. Ángel Rumiguano located in the province of Bolívar, Guaranda canton, Julio Moreno Parish, Cashapamba Site. Two varieties of cauliflower and three doses of chemical and organic fertilizers were evaluated. An analysis of variance ADEVA, Tukey's test at 5% was performed to compare treatments and factors A and B. Correlation analysis and simple linear regression. Economic analysis cost-benefit ratio B/C. Based on the analysis and interpretation of the results obtained in this trial, the following is concluded: In Factor A (Hybrids of cauliflower), the hybrid that best developed was the Skywalker with a yield of 26.631 kilograms per hectare in this agroecological zone. Factor B (dose of chemical fertilizer (NPK) and organic fertilizer (Ecoabonaza) in the Cashapamba agroecological zone and at the time of transplantation (July 1), allowed good phenological development and yield per hectare of 31.234 kilograms was B5: NPK (5.7 grams/plant) (N 160 kg/ha, P 80 kg/ha, K 240 kg/ha). In the interaction of factor A x B, although statistically there were no numerical differences, the treatment that presented the best yield with 35882 kg/ha was T5: Skywalker + NPK (5.7 grams/plant) (N 160 kg/ha, P 80 kg/ha, K 240 kg/ha), The variables that contributed to increase the yield were: Days to pellet formation (DFP) with 22%, Days to harvest (DC) with 24%, Plant height (AP) with 34% and Pellet Diameter (DP) with 30%. Economically, the technological alternative that presented a net benefit of $3.33 USD was T5: Skywalker + NPK (5.7 grams/plant) (N 160 kg/ha, P 80 kg/ha, K 240 kg/ha) with a benefit/ cost: B/C of $1.31 USD and an I/C revenue/cost ratio of $0.31 USD. |
