Evaluación de diferentes fertilizantes orgánicos e inorgánicos aplicados follarmente en la producción de forraje y semillas de pasto Arrhenatherum elatius (pasto avena)

Abstract

At the Tunshi Experiment Station, Chimborazo Province, the investigation on the evaluation of different organic and inorganic fertilizers foliarly applied in the forage and PASTURE seed production arrhenatherum elatius (oats pasture), was carried out. It was over a 4-month period and was evaluated under a completely at random blocks design, using 12 12 m² lots, 4 treatments (Fortaleza, Algalik, and Bioinicio Biol 200 l /ha), The results indicate that there were significant differences P ≤ 0.05, obtaining the best results with treatment two, Algalik 200 l/ha for: the lowest preflourishing time 38.67 days were recorded; the highest basal height at the preflourishing stage reached 40.93 cm, the best basal and aerial coverage reached a percentage of 34.83 and 45.81 in their order, the highest stem number for the preflourishing and posflourishing stages was 35.48 and 46.32 stems/plant respectively. The maximum forage production in the evaluation was 8.11 tons/ha/cutting. The dry matter production recorded 2.19 t/ha/cutting. The seed production 215.46 kg/ha / cutting. The germination percentage was 82%. The bromatological analysis shows a gross protein content and energy of 12.65% and 3728.12 Kcal/kg/DM respectively. The economic analysis reveals the benefit-cost for the forage and seed production of 1.46 and 1.55 USD. It is therefore recommended to use the foliar fertilizer Algalik 200 l/ha to attain a high pasture Arrhenatherum elatius (oat pasture), production in all its productives stages.
