Influence of Foliar Feeding of NPK (19:19:19) on Growth, Yield, and Quality of Cucumber (Cucumis sativus L.) cv. Kalyanpur Green

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.
