The experiment was conducted on CIM-Jeevan variety and it was laid out in factorial randomized block design with 24 treatments involving different combination of organic manures and inorganic fertilizers with three replications. The three main factors considered having different levels in which 3 levels of FYM (M0, M1 and M2, respectively), 2 levels of Vermicompost (V0 and V1, respectively) and 4 levels of nitrogen, phosphorous and potassium (F0, F1, F2 and F3, respectively), Among different treatment combinations, application of M2V1F3 (15 tonnes FYM, 2 tonnes vermicompost and fertilizer combination of 150: 60: 60 kg NPK per hectare) had recorded significantly maximum plant height (79.30 cm), number of leaves per plant (280.33), number of branches per plant (59.90) at harvest. Whereas, the maximum plant spread (497.67 cm), leaf area (3.32 cm2), leaf area index (3.29), Cumulative growth rate (11.53 g/m2/day), Absolute growth rate (0.23 g/day), the nutrient content in plants (N-2.70 %, P2O5 -0.51 % and K2O – 2.63 %), nutrient uptake by the plants (N- 178.59, P2O5-33.72 and K2O-173.88 kg/ha), total dry matter accumulation (16.17 g/plant), fresh herbage yield (14.79 t/ha), dry herbage yield (6.61 t/ha), the highest net return (Rs. 2,48,709 /ha) and benefit cost ratio (4.01) were recorded with the combined application of M2V1F2 (15 tonnes FYM, 2 tonnes vermicompost along with 100: 45: 45 kg NPK per hectare). The maximum phyllanthin content (0.98 %) was recorded with the application of organic manures M2V1F0 (15 tonnes of FYM along with 2 tonnes of vermicompost) and acceptable quantity of Phyllanthin was obtained with M2V1F2 (15 tonnes of FYM 2 tonnes of vermicompost along with 100: 45: 45 kg NPK/ha). Hence, it can be concluded, that Phyllanthus amarus variety CIM-Jeevan has shown better performance under dry land situation with application of M2V1F2 in terms of growth, yield, acceptable quantity, quality of phyllanthin and also with regard to economics and soil health.EnglishThesis
