Calidad bromatológica de forraje verde hidropónico de gramíneas con tres niveles de fertilización.

Abstract

The objective of this study was to determine the bromatological quality of hydroponic green forage of wheat (Triticum aestivum) using three levels of fertilization. A Completely Randomized Design (CRD) with a factorial arrangement A × B was employed, where A corresponds to different types of fertilizer and B to the doses, resulting in 6 treatments with 4 repetitions each. Data were analyzed using R software (version 4.3.2, 2022). The treatments were: T1 (Amino Tech 50% 0.20 ml/m²), T2 (Amino Tech 75% 0.30 ml/m²), T3 (Amino Tech 100% 0.40 ml/m²), T4 (AlgaFert 50% 0.10 ml/m²), T5 (AlgaFert 75% 0.15 ml/m²), T6 (AlgaFert 100% 0.20 ml/m²), and T7 (Control 0% 0 ml/m²). The treatment with Algafert Eco at a dose of 0.2 ml/m² presented the most favorable results, reaching a dry matter content of 21.25% and a forage yield of 9.39 kg/m². In the bromatological analysis, Algafert showed the best results: 24.32% protein at a dose of 1 ml/m², 3.79% ether extract at a dose of 1.5 ml/m², and 62.44% energy content at a dose of 1 ml/m². Aminotech, at a dose of 0.20 ml/m², reported an ash content of 3.73%, and at a dose of 0.40 ml/m², showed the highest fiber concentration with 12.65%. These results suggest that, regardless of the applied dose, the contents of protein, ether extract, energy, ash, and fiber vary according to the type of biofertilizer used.
