Split-root Water Application to Highbush Blueberry Plants

Abstract

Watered split-root portions of 2-year-old plants of ‘Bluecrop’ blueberry ( Vaccinium corymbosum L.) exhibited significantly greater shoot dry weight, shoot thickness, shoot length, mean number of shoots, and leaf dry weight than nonwatered portions. Watered portions blossomed, produced fruit, and set new flower buds while existing flower buds died and no new flower buds formed on the nonwatered portions.
