【 摘 要 】

This research was conducted to investigate harvest index and yield components of aerobic rice (Oryza sativa) under effect of water, varieties and seed priming in the tropical region. The experiment was set in split-split plot design. The treatments were priming seed with poly ethylene glycol (PEG), treated (P1) and untreated (P0) as sub-sub-plot, Three aerobic rice cultivars as sub-plot consisted of Inpago 8, new potential one (V1), IR64, susceptible aerobic rice cultivar (V2) and Situbagendit, a normal aerobic rice cultivar (V3) as sub-plot, three irrigation intervals namely irrigated every 5 days (W1), irrigated every 10 days (W2) and irrigated every 15 days (W3) set as main plot. Yield components and harvest index parameters were calculated. Results indicated significant and insignificant difference, in spite these, there was no significant difference the date of W1 and primed seed revealed the highest data compared with W2, W3 and non-primed seed. High harvest index revealed by W1V1P0was 0.827 and the smallest by W1V3P1. Grain yield ranging between 4.49-1.60 ton ha-1and straw about 15.39-5.33 ton ha-1depend upon aerobic rice cultivars and water availability. More research about aerobic rice technology need to face water problem in the future.
