Ítem Productividad y tamaño de grano en el cultivo de la quinua bajo la aplicación de fertilizantes biológicos, orgánicos y de síntesis química en el municipio de Silvia, Cauca, Colombia(Universidad Icesi, 2024-12-01) Duque Hoyos, Natalia Andrea; Ortiz González, Daniel FernandoQuinoa cultivation has gained importance in recent years due to its agronomic and nutritional benefits; however, there is a challenge to explore sustainable alternatives for fertilization. The objective of this research was to evaluate the yield and grain size of this crop in the municipality of Silvia, Cauca, under different combinations of fertilizers: biological (3.7 L.ha-1 of ACF-SR®), organic (1 t.ha-1 of compost), chemical edaphic (90-60-52 kg.ha-1 of NPK), and chemical foliar (1.5 L.ha-1 of Agrimins completo®), which resulted in seven treatments: T1: Control, T2: Edaphic chemical fertilizer, T3: Foliar chemical fertilizer, T4: Biological fertilizer, T5: Biological fertilizer + Organic fertilizer, T6: Biological fertilizer + Chemical fertilizer, and T7: Biological fertilizer + Edaphic chemical fertilizer + Organic fertilizer. A randomized complete block experimental design was used, and data analysis was performed through a one-way ANOVA with a significance value of 0.05. The findings of this study indicated that the exclusive application of biological or synthetic chemical fertilizers improves the quality and production of quinoa, and their choice of use depends on the production approach. However, the best results were obtained when an integrated fertilization was implemented, which included the simultaneous application of the three types of fertilizers (T7), achieving the highest yield of 4.17 t.ha-1 and the highest percentage of large grain with 57% of the harvest, which were 4.2 and 3.6 times greater in relation to the control.
