Bajra popularly known as Pearl millet, cattail millet or bulrush belongs to the family Graminea.
The crop is cultivated for grain as well as for fodder in the arid region of Africa and
Asia and as a pasture in U.S.A. It is originated in India or Africa. It is grown all over
India except Assam and part of northeast India.
Climate and soil:
The crop has a wide adaptability as it may grow under different day lengths, temperature and
moisture stress. Most of the varieties developed in India are photosensitive which helps
in growing the crop during monsoon, rabi and arid season. It requires low annual rainfall
ranging between 40-50 cm and dry weather. The crop may tolerate drought but cannot
withstand high rainfall of 90 cm or above. Light soils of low inherent fertility good
drainage, mild salinity are best type for this crop. Crop does not tolerate soil acidity
The crop needs very fine tilt because the seeds are too small. 2-3 harrowings and a ploughing
is followed so that a fine tilth may be obtained to facilitate the sowing and proper
distribution of seed at appropriate depth.
NBH-149, VBH-4 developed for Andhra Pradesh,
Madhya Pradesh, Gujarat, Maharashtra are capable of producing 14% higher yield.
ICM4-155 gave higher yield than the standard check and adopted for all growing tracts of
India.Also H-306, NH-338 and hybrid like MP-204, MP205 have been identified.
Sowing time :- Most appropriate time
of sowing is middle or last week of July
Seed rate and Spacing:-
4-5 kg/ha for drilling method
2.5-3 kg/ha for dibbling method
spacing 40 45 cm between rows, 10 15 cm within rows.
Seed treatment- The organo-mercurial compound Ceresan, Agrosan should be used @ 2.5-3
kg/ha to control seed borne diseases
Generally the crop requires low quantity of nutrients. But All India Co-ordinated Millet
Improvement Project has proved that new plant types of bajra especially hybrids respond to
very high doses of fertilizers.
Under rainfed areas
application of organic manures such as FYM or compost helps in increasing the crop yield
at the rate of 150-200 quintals/ha 80 100 kg N:40-50 kgP:40-50kgK is recommended
dose for hybrid variety.
applied in split doses, half of nitrogen, full phosphorus and potash should be basal
placed at the time of sowing . The organic manures must be applied 20 days before the
sowing of the seeds for full decomposition. One fourth dose of nitrogen should be applied
about 30 days and 60 days after sowing.
Thinning or gap filling is followed at the time of first interculture. Hand weeding is followed to
control the weeds or application of Atrazine @ 0.5 kg/ha would take care of most of the
Bajra is grown rainfed and crop being drought resistant hardly needs any irrigation, however it
is observed that the yield may be significantly increased by irrigating the crop at
critical growth stages like maximum tillering, flowering and grain filling stage.
Therefore light irrigations and efficient drainage is very essential for bajra production.
Plant protection measures
a) Insect pests:
Stem bores and
grasshoppers are serious pests of bajra controlled by two sprayings with 2 litres of
Eldrin 20 c.c and grasshoppers may be controlled by dusting the crop with BHC 5 percent.
Downy mildew- for controlling this disease
seed treatment with fungicide like Dithane Z-78 or M-45 @ 2.0kg/ha in 800-1000 lit. of
Smut- Treatment with Ceresan or Thirum @ 1-2 g/kg seeds is effective.
Ergot- Seed treatment with 20% common salt solution followed by washing with fresh water
and then treating with Ceresan or Thirum @ 1-2 g/kg seeds is effective
Harvesting and Storage:
Harvesting and threshing:
The crop is harvested when grains become
hard enough and contain moisture. Two methods are adopted for harvesting the crop Cutting earhead
i) from standing crop followed by cutting of remaining plants later
ii) Cutting of entire plants by sticks and stalking the plants for five days in sun
for obtaining grains. Grains are separated either by beating the earheads with sticks or
by trampling the earheads under bullock feet.
The separated grains must be cleaned and dried in sun to bring about 12-14%
moisture after which the grains may be bagged and stored in a moisture proof store.
Yield: Irrigated crop yields 30-35 quintals/ha, while unirrigated crop yield 12-15
