Abstract
Introducing new plants to an area may have both positive and negative effects on the environment, economy and community. To minimise the negative environmental impact of introducing new agricultural species, DPIRD conducts a risk assessment procedure based on widely accepted scientific standards. This report assesses Japanese millet (Echinochloa esculenta). Japanese millet is a tall, fast-growing annual summer crop that has been domesticated since 2000BC from Japan. It has been cultivated both for human consumption and as a fodder by tribal communities in Asia including in India, Japan, and China (Sood et al. 2015). Japanese (Shirohie) millet is a dual-purpose millet (grain and grazing), although generally grown for only one use to maximise production. It is a temperate grass that tolerates relatively cool soil temperatures for germination (14°C) compared with other species of millet (Hills and Penny 2005). In south-western Australia Japanese millet is a minor fodder crop sown in late winter-spring when seasonal conditions are favourable to provide green feed in late spring and over summer. Japanese millet has not been evaluated under irrigation in northern Western Australia (WA), as the focus has been on pearl millet which is more drought and heat tolerant.
