• Optimum temperature for its cultivation is 20°c-30°c.
• During its vegetable growth, moist weather is very beneficial.
• Bajra is grown as Kharif crop in North India and in southern parts it is known as Summer crop under irrigation.
Soil Requirement
• It is grown in wide variety of soil.
• It grows best in black cotton soil, sandy loam soil which has good drainage system.
• Acidic and water logging soil is not preferred.
• For its cultivation, avoid saturated soil.
• The crop grows well in soil with low pH range.
• It is sensitive to acidic soil.
Land Preperation
• The field should be finely tilled by 2-3 harrowing followed by a plowing.
• Weeds should be destroyed if any during the land preparation.
Sowing Time
In India, it is grown in three seasons
1. Kharif- June-October(rainfed)
2. Winter- November-February(rainfed)
3. Summer- March-June
• It is grown in Tamil Nadu, Karnataka, Punjab and Gujarat during summer as an irrigated crop.
• Sowing should be done with onset of monsoon i.e. first fortnight of July in North and central parts of the country.
• To obtain higher production of summer pearl, it should be sown in the last week of January to 1st week of February.
• For rabi season, first fortnight of October is appropriate in Tamil Nadu.
• The optimum time to sow Bajra is middle to last week of July.
Seed Rate
• For dibbling method seed rate should be 3-3.5kg/ha.
• For drilling method seed rate should be 4-5kg/ha.
Spacing
• Row spacing of 40-45cm should be maintained.
• Plant to Plant spacing of 10-12cm should be maintained.
• Depth should be 2-3 cm.
Irrigation
• It is a highly drought tolerant crop and water requirement is 300-350mm.
• Irrigation at available soil moisture of 50% or ideal IW/CPE ratio 0.4 is sufficient.
• Tillering and flowering are critical stages.
• For panicle initiation three irrigations can be recommended, flag leaf and flowering in addition to sowing irrigation under limited moisture conditions.
• Normally 5 irrigations are recommended.
• Summer irrigated pearl millet requires 6 irrigations for high yields.
Manures & Fertlizers
• If one is cultivating commercial hybrid Bajra, even Bajra needs few nutrients.
• Application of 10-15 tonnes of compost or farm yard manure per hectare is required for requirement of fertilizer of local varieties of Pearl millet.
• For maximum profit on the basis of soil test value, fertilizer should be given.
• Almost 3-5cm below the seed, half dose of nitrogen and full doses of phosphorus and potassium should be applied.
• Foliar spray of 3% urea is also recommended in barani conditions.
Harvesting
• When grains become hardy and also contain moisture, the crop is ready to harvest.
• Cutting earhead or cutting entire plants by sticks are 2 methods that can be followed in harvesting.
• For 4-5 days in the sun stalk the cut plants for drying grains.
• By beating the earheads, grains can be separated.
Yield
• Grain-23-35 qtl/ha, Fodder-100-120 qtl/ha, Under Irrigated condition.
• Grain-12-15 qtl/ha, Fodder-70-75 qtl/ha, Under rainfed condition.
