Producción de avena en corte e hidropónica sembrada a diferentes dosis y tiempo de cosecha

Abstract

This study aimed to evaluate cut and hydroponic oats' production and nutritional quality (A. elatius) under different planting densities and harvest times. A 3x3x3 factorial experimental design was used, which consisted of 3 treatments: T1 (cut oats), T2 (hydroponic oats with nutrient solution) and T3 (oats without nutrient solution). Each treatment had three replicates. The study factors were the sowing densities of cut oats (0.150 kg/m2, 0.200 kg/m2, 0.250 kg/m2), harvest time (45, 60, 75 days) and the sowing densities of hydroponic forage with and without solution were: 1.5 kg/m2, 3.0 kg/m2, 4.5 kg/m2, harvest times (8, 12, 16 days). Hydroponic cultivation conditions favored morphological development, agricultural yield, and plant height, which reduced cutting times and increased harvested forage volumes and forage weight. The combination of sowing density of 0.15 kg/m2 and harvesting every 75 days gave the best results. Hydroponic oat production with and without nutrient solution increased forage weight, protein percentage, fat and fiber content. Likewise, the economic analysis determined that hydroponic oats with nutritive solution recovered 0.44 cents for each dollar invested, the treatment that reached the highest profitability. Based on the results obtained, it was concluded that the production of hydroponic green forage under the effect of planting densities and harvest time influenced the production rates. It is an efficient alternative for small forage producers in the Ecuadorian highlands. Keywords: Costs, Germination, Nutrient solutions, Nutrient value
