Description
Setaria sphacelata is a widely sown pasture grass in the tropics and sub-tropics (Hacker and Jones, 1969). Its use is limited by low seed yields (10-80 kg/ha/crop) and the cold tolerant cv. Narok gives less seed than other cultivars (Bahnisch and Humphreys, 1977). In Queensland Setaria generally produces two crops a year with irrigation, but the seed yields are some of the lowest of any commercial species traded (Humphreys and Riveros, 1986). The objet of the present experimental work was to determine the optimum level of nitrogen and its time of application for maximum profit, and to study the seed yield components which were considered to be influenced by the rainfall pattern.
