About Lesson
Bajra
Introduction
- Scientific name: Pennisetum typhoides.
- Common name: Pearl millet, African millet.
- Quick growing, short duration fodder crop taking about 50-60 days to feed animal.
- Owing to high tillering, drought and heat tolerance, high photosynthetic efficiency and its widely adaptability to various soil types.
- Tolerant to saline sodic condition than jowar.
- Fodder is free from prussic acid and oxalic acids are within safe limits.
Climate:
- Requires warm and dry weather with intermittent showers of rain, followed by bright sunshine.
- Cultivation is restricted to areas receiving rainfall from 250-800 mm.
- Can withstand moisture stress condition and starts vigorous growth even with light showers of 25-30 nm.
Plant characteristics:
- Erect and tall grass growing upto 1-2.5 meter.
- Stems are solid with primary, secondary and sometimes tertiary branches.
- Tillers regenerate quickly after defoliation.
- Inflorescence is hairy.
- Root system is shallow and aerial rooting takes place to provide support against lodging of the stems.
Soil condition:
- Can be grown on alluvial sandy soils to red and medium black soils.
- Seed can germinate even under low moisture conditions.
- Field should be drained as water stagnation can be harmful.
- Acid, alkali and low-lying areas should be avoided to ensure good establishment and growth.
Seed-bed preparation
- Don’t respond to intensive or deep cultivation.
- Just enough cultivation may be given to uproot the weeds and prepare a fine and firm seed-bed.
- In heavy soils, harrowing rather than ploughing can may be done so that the soil is stirred to the minimum depth.
Sowing time:
- March-April in terai and foot hills.
- June-July as rain fed crop.
Sowing method, spacing and seed rate
- Seeds are sown by drilling or behind plough .
- Seedlings prepared in the nursery can be transplanted with the break of monsoon.
- Line spacing of 30-40 cm with a good irrigation facilities and fertile soils.
- In dry lands, the inter-row spacing can be increased to 60 cm.
- For drilling, 10-12 kg seeds/ha is enough, which could be about 12-15 kg/ha in case sown behind plough.
- 15-20 kg/ha in case of broadcasting.
- Dribbling requires 5-8 kg seeds/ha.
Crop mixture
- Can be grown in mixture with cowpea, velvet bean, green gram, and even with sunhemp.
Manuring
- 20t FYM/ha before sowing followed by 60-70 kg urea/ha; 125 kg superphosphate and 35-40 kg MOP/ha at sowing.
- 5 kg zinc sulphate per hectares ensures good growth for zinc deficit areas.
- High yielding varieties may be sprayed with 2% urea @ 15020 kg/ha for improving the protein content.
- In case of two-cutting, the second crop may be fertilized with 40-45 kg urea/ha about a week after harvesting the first crop.
Harvesting and yield:
- Harvested at the boot leaf stage or immediately after a few plants have flowered.
- Should not be delayed beyond 50% flowering stage as there is a sharp decline in the crude protein, and rapid increase in the crude fiber content of the fodder.
- Yields 150-200 qt green fodder/ha with low rates of fertilization.
- 700 qt/ha from multi-cut management system with dry matter content of about 18-20% and crude protein content of 10%.
