Abstract:
Bhumyamalaki is an annual small herb belongs to the family Euphorbiaceae, mainly known in Indian ayurvedic system for its medicinal properties. During 2018-19 in kharif, the field experiment was conducted with an objective of increasing yield in Phyllanthus amarus with different combinations of vermicompost and inorganic fertilizers under Northern Dry Zone of Karnataka at Main Horticultural Research and Extension Centre (MHREC), UHS, Bagalkot. Among different treatment combinations, application of V₁F₃ (2 tonnes vermicompost and fertilizer combination of 150: 60: 60 kg NPK per hectare) has recorded significantly maximum plant height (64.9 cm), number of leaves per plant (218.78), number of branches per plant (50.46), plant spread (57.07 cm²), leaf area (446.33 cm²), leaf area index (2.98), Cumulative growth rate (5.96 g/m²/day), Absolute growth rate (0.12 g/day), total dry matter accumulation (11.97 g/plant), fresh herbage yield (10.75 t/ha) and dry herbage yield (5.25 t/ha), the maximum nutrient uptake (N-121.52, P₂O₅-24.96, K₂O-107.73 kg/ha) by the plants, the highest net returns (132226) and B:C ratio (2.95). Whereas, the maximum Phyllanthin content (0.87%) was recorded with the application of V₁F₁ (2 tonnes of vermicompost and fertilizer combination of 50: 30: 30 kg NPK per hectare) and the maximum phosphorous availability in soil (39.21 kg/ha) was recorded with V₁F₀ (2 tonnes vermicompost and fertilizer combination of 0: 0: 0 kg NPK per hectare).
