A field experiment carried out in Vegetable Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India follows a randomized block design with seven treatments and three replications to evaluate the effect of pre-harvest application of Sodium-Para-Nitrophenolate on growth and yield characters of cucumber (Cucumis sativus L.) cv. ‘Swarna Ageti’ during Kharif 2019. The treatments including various doses of Sodium-Para-Nitrophenolate i.e. 0.1% SL (T₁), 0.2% SL (T₂), 0.3% SL (T₃), 0.4% SL (T₄), 0.5% SL (T₅) and untreated control (T₇) applied at 30, 45 and 60 days after sowing (DAS) with replications each. The results revealed that the treatment T₅ viz. Sodium-Para-Nitrophenolate 0.5% SL was found to be the most effective treatment, which significantly influenced the number of primary branches per vine, vine length, days to the appearance of first male and female flower, days to 50% flowering, number of male and female flowers per plant, and sex ratio as compared to control. In addition, treatment T5 also increased the yield parameters of cucumber such as fruit length & width, average fruit weight, yield per plot and overall yield.
