The present investigation was carried out in the net house of the Department of Plant Physiology, Bhubaneswar, Odisha, India to screen twenty popular cucumber genotypes by foliar application of ethrel @300mg/L and to recommend and to grow under field condition suitable to Coastal Odisha Agro-climate. Primarily, the screening methods focus on one or more customary growth sites (bud, leaves, stem, flower and fruits) and on the basis of their growth, flowering (male: female), fruit set and yield a conclusion was derived The pot experiment was carried out from October 2019 to January 2020 in net house condition with factorial completely randomized design (CRD) and was replicated twice. The first ethrel (2-chloro- ethane phosphonic acid) @300ppm treatments were applied when the second true-leaf was fully expanded and a second application was made seven days later including a control spray application of distilled water. The foliage application of ethrel increased vine length (133.50 cm), ma
