Abstract
Abstract In field experiments with cucumber ( Cucumis sativus L.) on both sandy and clay loam soils (2-chloroethyl)phosphonic acid (ethephon) at 125 or 250 ppm applied twice to the foliage was more effective in promoting pistillate flowers and yield on ‘Wisconsin SMR 58’, a monoecious cultivar, than granular ethephon applied at various rates as a sidedress at planting, placed directly on the seed at planting, or applied as a sidedress in the first true-leaf stage. Foliar sprays on ‘Pioneer’ were effective in reducing the number of staminate and increasing the number of pistillate flowers. However, ethephon applied by any method did not increase yields in ‘Pioneer’, a predominantly pistillate cultivar.
