An experiment was laid out during 2006-2007 with 18 treatment combinations of 3 spacing and 6 nutrition levels in a factorial randomizes block design with 3 replications. Among the plant spacing, 30cm 40 cm recorded higher plant spread 37.80cm), leaf area (216.23 cm2) , number of leaves/plant (11.13), average leaf weight (22.13 g). Petiole length (12.95cm), petiole mid-rib weight (8.95 g), leaf weight/plant (166.04 g), dry matter content (13.69%), total chlorophy III content (61.06 mg/100 g), total carotenodis (2.53 mg/100 g) and vitamin C content (100.65 mg/100g). But significantly higher leaf yield (26.25 tonnes/ha) was recorded with a spacing of 30cm 20 cm due to large plant population/unit area. Among the nutritional levels 50% recommended fertilizers dose + 3 tonnes vermicompost/ha recorded significantly higher plant spread (43.17 cm), leaf area (268.36 cm2) , number of leaves/plant (12.65), average leaf weight (24.124 g), during of picking (45 days), leaf weight (188.93 g/plant) and leaf yield (26.25 tonnes/ha). The highest net return of Rs 2 12 801 and benefit: cost ratio of 4.28 was accrued with 30cm 20 cm plant spacing along with 50% recommended fertilizers dose+3 tonnes vermicompost/ha.
