Bajra (Pearl Millet)
Pennisetum glaucum
📖 About this plant
Bajra (Pennisetum glaucum), also known as pearl millet, bajri in Marathi/Gujarati, sajje in Kannada, kambu in Tamil, and gero in Hausa, is a tall annual grass in the Poaceae family — one of the most drought-tolerant cereals in the world and a staple food for over 100 million people in the semi-arid tropics of Africa and India. Native to the Sahel region of Africa (south of the Sahara), pearl millet was domesticated over 4,000 years ago and arrived in India around 1500 BC — where it became the staple grain of the dry regions of Rajasthan, Gujarat, Maharashtra, Karnataka, and Tamil Nadu. India is today the worlds largest producer of pearl millet, with major cultivation in Rajasthan (the largest producer — especially the arid western districts), Maharashtra, Gujarat, Uttar Pradesh, Haryana, Tamil Nadu, and Karnataka. The plant is a tall (1-3 m) robust grass with long sword-shaped leaves and a dense cylindrical spike-like flower head (the “ear” or “panicle”) that is 20-50 cm long and resembles a fat green/brown caterpillar. The grain is small (3-4 mm) and round, ranging in color from yellow to grey to brown to almost white. Pearl millet is exceptionally nutritious — higher in protein (10-12%) than rice or maize, rich in dietary fiber, iron (the highest of any cereal), zinc, magnesium, potassium, B vitamins, and antioxidants. It is also gluten-free. In India, bajra is ground into flour and made into rotis (bajra roti — the famous flatbread of Rajasthan and Gujarat, served with ghee and jaggery in winter), bhakri (the thick flatbread of Maharashtra), used in porridge (kambu koozh in Tamil Nadu — a fermented summer drink), in dosa and idli batters (mixed with rice and urad dal), in ladoos (with jaggery and ghee), and as a popped snack (bajra kurdi). Bajra is also a major fodder crop — the leaves and stems are fed to cattle, especially in dry regions where other fodder is scarce. In Ayurvedic medicine, bajra is considered warming and is recommended in winter, for vata and kapha doshas, and for strengthening the body.

💡 Care tips
- Direct sow seeds at the start of the monsoon (June-July in India). Sow seeds 2-3 cm deep, broadcast or in rows 30-45 cm apart. Thin seedlings to 15-20 cm apart after establishment. Plant in full sun in sandy, well-draining, even poor soil. Bajra thrives in the hottest, driest conditions where other cereals fail — ideal temperature 25-40°C, low humidity, low rainfall (40-60 cm/year is sufficient). It does NOT tolerate waterlogging. Water sparingly — bajra is exceptionally drought-tolerant and suffers from overwatering. Water during germination and flowering if rainfall is inadequate; otherwise rely on monsoon. Do NOT apply high nitrogen — bajra is a low feeder and excessive nitrogen causes lodging (falling over). Apply phosphorus and potassium at planting if soil is poor. The plant grows rapidly — 1-2 m in 50-70 days. The ear (panicle) matures 70-100 days after sowing. Harvest when ears turn from green to straw-brown and seeds become hard — cut ears individually or cut entire plants, dry in the sun for 3-5 days, then thresh to release grain. Thresh by beating dried ears with sticks or by trampling with cattle. Winnow to remove chaff. Dry grain to 12% moisture before storage. Store in airtight containers or grain bags in a cool, dry place — add dried neem leaves to prevent insect infestation. Save seeds from the best plants — they remain viable for 1-2 years. Bajra is a great rotation crop — its deep roots (1-2 m) break up hardpan and improve soil for the next crop. Popular Indian hybrids and varieties include HHB-67 Improved, ICTP-8203, Pusa Composite 612, ICMH 356, RHB-177, and the famous "bio-fortified" iron-rich variety Dhanashakti. For home gardeners, bajra is one of the easiest grains to grow — fast, drought-tolerant, and ornamental (the dramatic feathery ears look beautiful in a sunny border).
