Abstract: The present study was executed to identify the suitable integrated nitrogen management on vine growth and leaf characters of betel vine (Piper betle L.) cv. Simurali Deshi, Simurali Bhabna and Halisahar Sanchi in new alluvial zone of West Bengal. The experiment was laid out in Randomized Block Design, replicated thrice with eight treatments of integrated nitrogen management. It was noted that treatments in combination with inorganic and organic sources of nitrogen produced better results than the treatments with sole application of organic source of nitrogen. Application of 100% recommended dose of nitrogen (200 kg/ha) in the form of mustard oil cake and urea in equal proportion (1:1) recorded the highest vine growth (273.57 cm/ year) in Simurali Deshi, leaf petiole length (8.04 cm) in Simurali Bhabna, intermodal length (4.88 cm) in Halisahar Sanchi, number of branches per vine (11.43) in Simurali Bhabna, leaf length (12.24 cm) in Simurali Bhabna, leaf breadth (10.05 cm) in Halisahar Sanchi, leaf area (106.34 cm²) in Halisahar followed by application of nitrogen from cow dung manure and urea in 1:1 ratio (T₂).
