Growth—

Setaria italica is a plant of the tmperate and subtropical zones, amenable to cultivation in the tropics where it is found at elevations up to 2,000 metres. It grows best in areas where annual daytime temperatures are within the range 16 - 26°c, but can tolerate 5 - 35°c[1]. It is intolerant of frost[2]. It prefers a mean annual rainfall in the range 500 - 700mm, but tolerates 300 - 4,000mm[1]. Grows best in a sunny position[3, 4]. Succeeds in any well-drained soil from light sands to heavy clays, preferring fertile conditions[3, 4]. Established plants have a deep root system and are very drought resistant[5, 6, 2]. Prefers a pH in the range 6 - 6.8, tolerating 5.5 - 8.3[1]. Plants can mature a crop in 60 - 120 days from sowing the seed, depending on conditions and variety[1]. Seed yields of 800 - 900 kilos per hectare can be attained from rain-fed crops; this has been increased to 1,800 kilo in China with selected forms and a rainfall of less 900mms[4, 2]. Experimental yields of 11 tonnes per hectare have been obtained with irrigation[4]. There are many named varieties[7, 8].

Propagation

Seed - sow early spring in a greenhouse and only just cover the seed. Germination is usually quick and good. Prick out the seedlings into individual pots as soon as they are large enough to handle and grow them on fast. Plant them out in late spring, after the last expected frosts. Whilst this is fine for small quantities, it would be an extremely labour intensive method if larger amounts were to be grown. The seed can be sown in situ in the middle of spring though it is then later in coming into flower and may not ripen its seed in a cool summer.
