Abstract
The drumstick (Moringa oleifera Lam.) variety Thar Harsha is an annual type having densely foliaged with dark green broad leaves (54.5 cm long and 35.2 cm width). The plants grows up to 405.6 cm and spreads 330.2 cm (E-W) and 390.4 cm (N-S). The fruiting in Thar Harsha starts late (March to May) as compared to PKM-1 (February-March). Each plant produces about 314 pods in a year, and its yield potential of 53–54.7t/ha. It is superior in pod size and yield (85.6%) over PKM-1. It has high protein (9.3 g), Vitamin A (9783IU) and Vitamin C content (246 mg) per 100 g of fresh edible pods. It have recorded comparatively higher antioxidants contents and activity viz. total phenols (657.69 and 36.23 mg GAE/100 g), total flavonoids (406.28 and 298.46 CE mg/100 g), DPPH (29.07 and 21.53 µmol TE/g), FRAP (66.37 and 34.41 µmol TE/g)and CUPRAC (99.07 and 44.64 µmol TE/g) in leaves and pods, respectively. The variety Thar Harsha recorded comparatively highest dry matter (25.52 and 20.69%), protein (20.25 and 9.33 mg/100 g), nitrogen (3868.03 and 3653.16), phosphorus (187.91 and 113.60) potassium (1714.12 and 942.33), Calcium (4318.38 and 1983.15), Sulphur (4397.18 and 2038.49), Iron (44.6 and 32.76), Manganese (3.79 and 1.21), zinc (20.55 and 12.14) and Cu (1.15 and 0.83) in (mg/100 g dry powder) leaves and pods, respectively.
