Abstract
Black rice is known by many names such as forbidden rice, imperial rice, king’s rice, purple rice, heaven rice and prized rice and is packed with high level of antioxidants and micronutrients. A present investigation was carried out during the Kharif season of 2024 at Himalayan University farm, Jollang, Itanagar, to determine the response of nano fertilizer on growth of black aromatic rice (Oryza sativa L. indica). The experiment was outlined in a Randomized Block Design (RBD) with eight treatment and three replications. The treatment included combination Nano Nitrogen and Nano Zinc. The study recorded significance difference among treatments in terms of plant height, leaf length, number of tillers, dry weight and width of leaves of plant at 30, 60 and 90 DAT. The result revealed that the treatment T5 (Nitrogen at 4ml/L + Nano Zinc at 2ml/L) was found to be best treatment for obtaining maximum plant height, leaf length, number of tillers, dry weight and width of leaves, this indicating the combined effect of nano fertilizer on black aromatic rice.
