The experiment was conducted in Factorial RCBD design and four replications. The experiment had ten treatment combinations consisting of two factors i.e. two tulsi varieties and five different organic manures. Among the various treatment combinations Rama tulsi with 100 per cent recommended nitrogen applied through vermicompost recorded higher plant height (86.60 cm), leaf area (7,267 cm2 plant-1), leaf area index (2.68), plant spread (N-S) (78.85 cm), plant spread (E-W) (79.30 cm),chlorophyll content (46.52 SPAD values). Fresh weight of flower head per plant (100.75 g), dry weightof flower head per plant (39.45 g), fresh weight of shoot per plant (465.05 g), dry weight of shoot per plant (142.01 g), fresh weight of herb per plant (565.70 g), dry weight of herb per plant(181.46 g), fresh herb yield per plot(19.63 kg), dry herb yield per plot(8.22 kg), fresh herb yield (14.60 t ha-1), dry herb yield (6.11 t ha-1), oil recovery (0.32 g 100g-1), oil yield (20.04 kg ha-1), nitrogen uptake (116.13 kg ha-1), phosphorus uptake (31.38 kg ha-1) and pottasium uptake (127.91 kg ha-1) were also higher in the same treatment. Rama tulsi with 100 per cent recommended nitrogen applied through poultry manure recorded higher number of branches (24.45), fresh weight of 1000 leaves (82.61 g), available P (35.73 kg ha-1) and available K (234.87 kg ha-1). Higher nitrogen uptake (175.93 kg ha-1) was observed in Rama tulsi with 100 per cent recommended nitrogen applied through farmyard manure.EnglishThesis
