Dosis de zeatina como estimulante de crecimiento y su efecto en el maíz forrajero hidropónico

The present study aimed to evaluate three doses of zeatin (1g, 2g, and 3g) as a growth stimulant in hydroponic green forage (FVH) of corn. The investigation took place in the cattle herd, located in the Polytechnic Campus, site El Limón, Bolívar canton, province of Manabí. It was developed under a DCA, and the following results were obtained in the different parameters: In the productive parameters it was observed that the highest average root length (11.39 cm), leaf length (15.08 cm), height of the plant (25 cm) corresponds to the treatment with 3 g of zeatin, while the greatest biomass was obtained with the application of 2 g of zeatin (2.22 kg). In the bromatological analysis, significant differences (p <0.05) could be observed between treatments; a mean Crude Protein (13.22 ± 0.25%) was obtained in favor of treatment with 2 g of zeatin. In what corresponds to Dry Matter (14.35 ± 0.28%) Neutral Detergent Fiber (42.59 ± 1.13%), phosphorus (0.40 ± 0.014%) were superior in the treatment with 1 g of zeatin. And the largest increase in ashes (3.78 ± 0.30%) and Calcium (0.243 ± 0.024%) was obtained with 3 g of zeatin. It is concluded that the addition of zeatin positively influenced the productive parameters and quality indicators in the FVH of corn. The economic analysis showed that the greatest benefit / cost was presented in Treatment 0 and 1 with a ratio of 1:13 (profit of 13% of the USD investment). It was concluded that zeatin treatments are not profitable compared to a balanced food.
