Eficiencia nutricional a la aplicación de cinco bioestimulantes para la producción de semilla certificada de cebada (Hordeum vulgare), variedad cañicapa, en Laguacoto III, provincia Bolívar
Barley (Hordeum vulgare L.) is the fifth largest production cereal in the world, with 50% of the area and 63% of the production volume concentrated in Europe. In Ecuador, only 24 000 T/year are produced, and with production costs of up to $700 per hectare. In Ecuador, the province that occupies the...

In Ecuador, only 24 000 T/year are produced, and with production costs of up to $700 per hectare. In Ecuador, the province that occupies the first place of production is Imbabura with 3,440 metric tons, followed by the province of Chimborazo with 3,200 metric tons of production. This research was reflected in the agroecological zone of Laguacoto III, belonging to the parish Veintimilla of the canton Guaranda, located at an altitude of 2 622msnm. The objectives set were; I) Identify the main productive characteristics of barley cultivation, II) Validate the biostimulant that generates the best productive efficiency in barley cultivation, III) Establish the benefit-cost ratio in the different treatments. The type of statistical design that was used for this research was: Random Complete Block Design (DBCA) with three replications. The 5% Tukey Test was performed to compare treatment averages. Correlation analysis and linear regression of significant and highly significant variables. Economic benefit/cost analysis. The response of the biostimulants used, presented variability in the morphological descriptor, in the same way significant differences in several quantitative variables evaluated in the study area. The highest average yield was recorded in the T2 treatment (Calcium boron) with 3 590.5 kg/ha; then T3 (Humic acid) with 3 311.2 kg/ha; surpassing the T6 (Witness) that presented the lowest average with 1 769.9 kg / ha. The descriptors that affected barley yield were; Percentage of moisture in the grain and Hectolitrico weight; in the same way, the variables that increased the yield were Number of grains per ear and Yield per plot. Economically the technological alternative that presented the best performance was the T2 (Calcium boron) with 3 590.5 kg / ha; Therefore, it provides a benefit-cost ratio of $ 1.26 where it shows, that the barley producer for every dollar he has invested, obtains a profit of $ 1.26 dollars respectively. |
