Panicum sumatrense

Description

This species of cereal is similar in habit to the proso millet except that it is smaller. It is an annual herbaceous plant, which grows straight or with folded blades to a height of 30 cm to 1 m. The leaves are linear, with the sometimes hairy laminae and membranous hairy ligules. The panicles are from 4 to in length with 2 to long awn. The grain is round and smooth, 1.8 to long.

Subspecies

There have been two subspecies described:

• Panicum sumatrense Roth ex Roem. & Schult. subsp. psilopodium (Trin.) Wet.
• Panicum sumatrense Roth ex Roem. & Schult. subsp. sumatrense

Distribution and habitat

In the temperate zones of Asia: the Caucasus, China, East Asia and also in the tropics of the continent: India, Indochina and Malaysia.

It can withstand both drought and waterlogging. It can be cultivated up to 2000 m above sea level.

At the Indus Valley Civilisation sites of Harappa and Farmana, the millet assemblage was dominated by little millet. Over 10,000 grains of little millet were recovered at Harappa. At Harappa, little millet cultivation peaked at around 2600 BCE, accounting for around 5% of the total cereal assemblage.

Cultivation

The largest cultivation is in central India. Usually, it is planted using a seed drill. It can also if necessary be planted spoiled. The green plant can also be used in part as cattle feed. The straw can be mixed with clay or cement be used in construction.

The harvest yield is from 230 to 900 kg/ha.

Pests

Pests include the shoot fly Atherigona pulla, which also affects proso millet.

Other insect pests include:

• shoot fly, Atherigona miliaceae
• armyworms, Mythimna separata and Spodoptera frugiperda

;Leaf feeders

• caterpillars: Aloa lactinea, Amsacta albistriga, Euproctis virguncula, and Paramsacta moorei
• flea beetles: Chaetocnema basalis, Chaetocnema indica, and Chaetocnema denticulata
• larvae of the leaf folder Cnaphalocrocis medinalis
• grasshoppers: Chrotogonus hemipterus, Acrida exaltata, Aiolopus simulatrix, and Aiolopus tamulus

;Earhead feeders

• bugs Nezara viridula and Dolycoris indicus

;Panicle pests

• spotted stalk borer Chilo partellus

;Others

• Nephotettix virescens, Nephotettix nigropictus, and Nisia atrovenosa
• sugarcane leafhopper, Pyrilla perpusilla
• midge, Orseolia sp.

Uses

Little millet is cooked like rice. Sometimes the millet is also milled and baked. The protein content of the grain is 7.7%.
