Abstract
El alza y escases de fertilizantes han reducido la producción de cultivos y esto ha repercutido en los precios de los alimentos. Objetivo fue determinar la dosis adecuada de compost a base residuos de mercado para mayor rendimiento de lechuga. Método se basa en investigación aplicada; por lo que se empleó el Diseño de Bloques Completamente al Azar que constó de 3 bloques y 5 tratamientos, estos fueron: T1 = 0, T2 = 45 g, T3 = 60 g, T4 = 75 g y T5 = 90 g/ planta y se aplicaron 7 días después del trasplante. Se evaluó características físicas de la planta y disposición de nitrógeno con relación a las dosis. Obtenidos los datos se procesaron mediante análisis de varianza y Duncan. Se determinó que T4 destacó en longitud de planta con 25.86 cm, pero T5 en peso de lechuga con 128.23 g, rendimiento con 12.25 tn/ha, diámetro ecuatorial con 21.12 cm y disposición de nitrógeno con 200.4 kg/ha. Concluye que la mayor dosis que es T5 obtuvo mayor rendimiento que se diferenció a 40.81 % respecto al testigo, esto se debe que se adiciono nitrógeno y otros nutrientes, lo cual hubo mayor disponibilidad que optimizó las reacciones bioquímicas y esto influyó en rendimiento.
The increase and shortage of fertilizers have reduced crop production and this has had an impact on food prices. The objective was to determine the adequate dose of compost based on market residues to increase lettuce yields. The method is based on applied research; therefore, a Completely Randomized Block Design was used, consisting of 3 blocks and 5 treatments: T1 = 0, T2 = 45 g, T3 = 60 g, T4 = 75 g and T5 = 90 g/plant, applied 7 days after transplanting. Plant physical characteristics and nitrogen availability were evaluated in relation to the doses. Data were obtained and processed by analysis of variance and Duncan. It was determined that T4 stood out in plant length with 25.86 cm, but T5 in lettuce weight with 128.23 g, yield with 12.25 tn/ha, equatorial diameter with 21.12 cm and nitrogen availability with 200.4 kg/ha. It is concluded that the highest dose, T5, obtained a higher yield, which differed by 40.81 % with respect to the control, this is due to the addition of nitrogen and other nutrients, which had a greater availability that optimized the biochemical reactions and this influenced yield.
