The present experiment was conducted during Zaid season of 2023-2024 at Department of vegetable science Kalyanpur, Kanpur. The trial was laid down in randomized complete block design (RCBD) with three replications and thirteen treatments viz. T₁- Control Plot water spray at 25,40 and 55 DAS, T₂- NPK (19:19:19:) @ 0.5% of foliar spray at 25 DAS, T₃- NPK (19:19:19:) @ 0.5% of foliar spray at 40 DAS, T₄- NPK (19:19:19:) @ 0.5% of foliar spray at 55 DAS, T₅- NPK (19:19:19:) @ 0.5% of foliar spray at 25 & 40 DAS, T₆- NPK (19:19:19:) @ 0.5% of foliar spray at 40 & 55 DAS, T₇- NPK (19:19:19:) @ 0.5% of foliar spray at 25,40 & 55 DAS, T₈- NPK (19:19:19:) @ 1.0% of foliar spray at 25 DAS, T₉- NPK (19:19:19:) @ 1.0% of foliar spray at 40 DAS, T₁₀- NPK (19:19:19:) @ 1.0% of foliar spray at 55 DAS, T₁₁- NPK (19:19:19:) @ 1.0% of foliar spray at 25 & 40 DAS ,T₁₂- NPK (19:19:9:) @ 1.0% of foliar spray at 40 & 55 DAS and T₁₃- NPK (19:19:19:) @ 1.0% of foliar spray at 25,40 & 55 DAS. Result of study revealed that maximum vine length (400.00 cm), first fruit harvest (53.927 DAS), fruit length (23.600 cm), fruit width (4.00cm), internode length T₁₃ (18.900 cm), number of fruits per vine (14.700), yield per plant (2.60 kg), yield per plot (23.900 kg), yield per hectare (98.200 quintal), Vitamin C (4.043 mg/100gm), TSS (3.693 %) and minimum days to first male flower (39.497 DAS), days to first female flower (39.800 DAS) and first fruit harvest (51.927) was found in treatment T₁₃ NPK (19:19:19:) @ 1.0% of foliar spray at 25,40 & 55 DAS. Keywords: Cucumber, NPK, foliar feeding, growth, and yield.
