“Influencia de la fertilización química y orgánica en la producción y calidad nutricional de mezclas forrajeras Lolium perenne y Trifolium repens en la Quinta Punzara”

The production of forage mixtures represents an efficient alternative for animal feeding, providing a balanced combination of both pasture production and quality. This research evaluated the influence of chemical and organic fertilization on the production and nutritional quality of forage mixtures with Lolium perenne and Trifolium repens. The study was conducted at Quinta Experimental Punzara, Loja canton, Loja province. A Completely Randomized Block Design (CRBD) with ten treatments and three replicates, totaling 30 experimental units, was used. The treatments were as follows: T1 (Ryegrass var. Tetraverde + White clover var. Ladino with chemical fertilization); T2 (Ryegrass var. Tetraverde + White clover var. Ladino with organic fertilization plus mycorrhizae); T3 (Ryegrass var. Tetraverde + White clover var. Ladino with organic fertilization); T4 (Ryegrass var. Tetraverde + White clover var. Ladino with mycorrhizal fertilization); T5 (Ryegrass var. Bandito + White clover var. Ladino with chemical fertilization); T6 (Ryegrass var. Bandito + White clover var. Ladino with organic fertilization plus mycorrhizae); T7 (Ryegrass var. Bandito + White clover var. Ladino with organic fertilization); T8 (Ryegrass var. Bandito + White clover var. Ladino with mycorrhizal fertilization); T9 (Ryegrass var. Tetraverde + White clover var. Ladino as control) and T10 (Ryegrass var. Bandito + White clover var. Ladino as Control). The evaluated variables were emergence, number of leaves, number of tillers, height, coverage, biomass, moisture, dry matter, ash, fat, and protein. For the statistical analysis, InfoStat software was used employing analysis of variance (ANOVA), and a Tukey test at 95 % confidence level was used for statistical differences. The variables that showed significant statistical differences were: Ryegrass tiller number (12), Raygrass leaf number (70 per plant), clover leaf number (29), Ryegrass height (38.43 cm), clover height (21.81 cm), coverage (98.93 %), biomass (3756.53 Kg/Ha), moisture (87.25 %), dry matter (12.75 %), ash (13.18 %) with treatment T5.
