Uses in Hawai`i

The Hawai`i Natural Resources Conservation Service Technical Guide includes Annual Ryegrass (cv. 'Tam 90') and Lolium rigidum (cv. 'Wimmera 62'). Their specification describes Annual Ryegrass as follows:

Evensen, Osgood and El-Swaify conducted five years of research with small grains as cover crops on sugarcane plantations for erosion and weed control. Variety trials for 51 cultivars of oat, barley, wheat, ryegrass and rye grain on Hawai`i, Molokai, and Lanai were compared. Of the annual ryegrass trials, varieties 'Alamo' and 'Tam 90' were the most promising (in terms of vigorous growth, rapid soil cover, weed suppression, low plant height, and lack of flowering). This information has applications for pineapple, coffee and tropical fruit tree orchards.
