Resumen
Antecedentes: El aumento de la rentabilidad en un cultivo puede obtenerse incrementando los rendimientos, la productividad o ambos, de modo de obtener mayor cantidad de hongos con el mismo esfuerzo.Objetivos: Buscar la tasa de inoculación óptima para incrementar la productividad del cultivo de una cepa altamente productiva de Pleurotus ostreatus.Métodos: Usamos como sustrato paja de trigo, se inocularon bolsas de 1 kg peso húmedo con diferentes porcentajes de inóculo (producido sobre sorgo) variando del 1 al 16.6 %.Resultados y conclusiones: Se obtuvieron fructificaciones en todos los tratamientos; el tiempo de incubación se redujo una semana inoculando al 13 y 16.6%. Observamos un aumento en los rendimientos a medida que aumentaba el porcentaje de inóculo. Los porcentajes de eficiencia biológica más altos se alcanzaron en las muestras con 13 y 16.6%, obteniéndose valores de 116,08 y 116.04% respectivamente, sin mostrar diferencias significativas entre ellos, pero si con el resto de los tratamientos. El número de ciclos de cultivo por año se incrementó a 5.5. Cuando evaluamos los kilogramos totales producidos en un año y los comparamos con el costo del inóculo, el balance económico muestra que al usar un porcentaje del 13%, el productor casi duplica sus ganancias.
Background: To increase profitability, it can be obtained by increasing yields, productivity or both, and in this way to obtain more fungi with the same effort. Objective: To seek for the optimal inoculation rate to increase the productivity of the culture of a highly productive commercial strain of Pleurotus ostreatus. Methods: Wheat straw was used as a substrate; bags of 1 kg wet weight were inoculated with different percentages of inoculum (produced on sorghum) varying from 1 to 16.6 %. Results and conclusions: Fruit bodies were obtained in all treatments; the incubation time was reduced by one week inoculating at 13 and 16.6 %. We observed an enhance in yields as the percentage of inoculum increased. The highest biological efficiency percentages were reached in the samples inoculated with 13 and 16.6 %, obtaining values of 116.08 and 116.04 % respectively, without showing significant differences between them even though there were differences among treatments. The number of growing cycles per year was increased to 5.5 inoculating to 13-16.6 %. When we evaluated the total kilograms produced in one year and compared them with the cost of the inoculum, the economic balance showed that by using a percentage of 13 %, the producer doubled his profits.
