The present study was conducted to study the effect of foliar application plant growth regulators i.e. maleic hydrazide and ethephon on vegetative growth, sex expression, fruit setting, and fruit yield of cucumber. The plant material included three cultivars of cucumber i.e. Poinsette, Punjab Naveen and Pant Khira 1 raised during summer season during 2014-2015. Growth regulators ethephon and maleic hydrazide were sprayed at different concentrations on two and four leaf stage. Foliar application of Ethephon application @ 200 ppm reduced the vine length to the maximum, but it improved the number of secondary branches and fruit weight per vine. Application of Maleic hydrazide and ethephon application @ 100 ppm led to early production and yield of cucumber. The investigation concludes that foliar application of maleic hydrazide and ethephon can help promote feminism and increase the yield of cucumber crop.
