Resumen
Se estudió el efecto de tres agotamientos de la humedad aprovechable del suelo en el cultivo del algodón, con el cultivar Stoneville 213. Los tratamientos fueron 25%, 50 y 75% de agotamiento de la humedad aprovechable antes y después de la floración, respectivamente. El análisis de rendimiento no se detectaron diferencias significativas entre tratamientos, que involucran de seis hasta 16 riegos durante el ciclo vegetativo, si bien conforme se aumentó el agotamiento de la humedad del suelo disminuyó la altura de la planta. Se sugiere regar solo cuando se agote el 75% de la humedad aprovechable, bajo condiciones como las del ensayo.
The effect of three available soil water depletion levels on the growth and yield of cotton, cv. Stoneville 213, was studied at Cañas, Province of Guanacaste Costa Rica. Treatments were 25, 50 and 75% available soil water depletion plus a combination treatment where irrigation was provided upon reaching 50% and 25% available water depletion before and after bloom, respectively . There were no significant differences among treatments in yield, yield components and flower shed although plant height decreased as soil water depletion increased. Under the conditions of the trial it is suggested that irrigation can be held until 75% available water depletion is reached.
