GENERAL INFORMATION
Wheat is grown on 13 percent of the cropped area of India. Next to rice, wheat is the most important food-grain
of India and is the staple food of millions of Indians, particularly in the northern and north-western parts of
the country.
It is rich in proteins, vitamins and carbohydrates and provides balanced food. India is the fourth largest
producer of wheat in the world after Russia, the USA and China and accounts for 8.7% of the world’s total
production of wheat.

LAND PREPARATION
After harvest of previous crop, the field should be ploughed with disc or mould board plough. Field is
usually
prepared by giving one deep plough with iron plough followed by two or three times local plough and
planking.
Carried out plough in evening time and kept furrow open whole night to absorb some moisture from dew.
Planking
should be done after each plough early in the morning.
SOWING
TIME OF SOWING
Wheat must be sown at the optimum time. Delayed sowing causes a gradual decline in the yield of wheat.
The time
of sowing is 25 October – November.
SPACING
For normal sown crop a spacing of 20 - 22.5 cm between rows is recommended. When sowing is delayed a
closer
spacing of 15-18 cm should be adopted.
SOWING DEPTH
The sowing depth should be 4-5 cm.
METHOD OF SOWING
1. Seed drill
2. Broadcasting method
3. Zero tillage drill
4. Rotavator
SEED
SEED RATE
Use seed rate of 45 kg per acre. The seed should be cleaned and graded thoroughly before sowing.

WEED
CONTROL
CHEMICAL WEED CONTROL: Preferred because of less labour requirement and no mechanical damage during
manual
weeding. As pre-emergence, apply Pendimethalin (Stomp 30 EC) @1 Ltr at 0-3 days before sowing in 200
litres of
water/acre. Use 2, 4-D @250 ml in 150 ltr water for controlling broad leaf weeds.IRRIGATION
Recommended time of irrigations is as below in the table

The number of irrigations required will vary depending upon soil type, water availability etc. Crown
root
initiation and heading stages are the most critical to moisture stress. For dwarf high yielding
varieties, give
pre sowing irrigation. For heavy soils, four to six irrigations are required
whereas for light soils 6-8 irrigations are necessary. Under limited water supply apply irrigation only
at
critical stage. When water is available for only one irrigation, then apply at crown root initiation
stage. When
two irrigations are available then apply at crown root initiation and flowering stage. Where three
irrigations
are possible, 1st irrigation should be given at CRI stage and 2nd at late jointing (boot) and 3rd at
milking
stage. CRI stage is most important stage for irrigation. It has been found that each week delay in 1st
irrigation from CRI stage results in yield reduction of 83-125kg per acre.
First irrigation should be given 20-25 days after sowing. This is crown root initiation stage and
moisture
stress at this stage will lead to yield loss. At tillering stage within 40-45 days after sowing, apply
second
irrigation. Third irrigation within 60-65 DAS at late jointing stage. At flowering stage (within 80-85
days)
give fourth irrigation. Fifth irrigation at dough stage (within 100-105 DAS).
PLANT PROTECTION
Aphids:
These are nearly transparent, soft-bodied sucking insects. When present in
sufficient numbers,
aphids
can cause yellowing and premature death of leaves. Infestation usually occurs during second fortnight of
January
till crop harvesting.
For management of Aphid, use chrysoperla predators 5-8 thousand/acre or use 50 ml/Ltr neem concentrate.
In
cloudy weather infestation of aphid is occurred. Spray with Thiamethoxam@ 80gm or Imidacloprid 40-60 ml/
acre in
100 Ltr of water.
Termite:
Termites attack the crop at various growth stages, from seedlings to
maturity. The severely
damaged
plants can be easily uprooted and look wilted and dried. In case roots are partially damaged, the plants
show
yellowing. To control broadcast 1 Ltr of Chlorpyriphos 20 EC mix with 20 kg sand/acre then applies a
light
irrigation.
Flag smut:
It is seed borne disease. Infection spread through wind. It is favoured
by cool, humid
conditions
during flowering period of the host plant. Treat the seed with fungicides like carboxyl (Vitavax 75 WP @
2.5
gm/kg of seeds), Carbendazim(Bavistin 50 WP)@2.5 gm/kg seed), Tebuconazole(Raxil 2 DS)@1.25 gm/kg of
seed) if
the disease level in the seed lot is high. If it is low to moderate, treat the seed with a combination
of
Trichoderma viride@4 gm/kg seed and half the recommended dose of Carboxin(Vitavax 75 WP)@1.25 gm/kg
seed.
Powdery mildew:
Greyish white powdery growth appears on the leaf, sheath, stem and
floral parts. Powdery
growth
later become black lesion and cause drying of leaves and other parts. When incidence of disease is
observed,
spray with wettable sulphur@2 gm/ Ltr of water or Carbendazim @400gm/acre. In case of high incidence,
spray with
Propiconazole@2 ml/ Ltr of water.
Brown rust:
It is favoured by warm temperatures (15-30° C) and humid conditions.
Brown rust is
characterized by reddish- brown spores that occur in oval or elongated pustules. The disease can develop
rapidly
when free moisture is available and temperatures are near 20° C. Successive generations of urediospores
can be
produced every 10-14 days if conditions are favourable.
For control of this disease, follow mixed cropping with suitable crops. Avoid excessive use of Nitrogen
fertilizer. Spray Zineb Z-78@400 gm/acre or Propiconazole@2ml/Litre of water.
Stripe/Yellow rust:
The ideal growth conditions for yellow rust are temperatures of
between 8-13° C for
spore
germination and penetration, and 12-15° C for further development and with free water. The yield
penalties from
yellow rust in wheat can range from 5% to as high as 30% in high disease pressure scenarios. The
pustules of
stripe rust, which, contain yellow to orange- yellow urediospores, usually form narrow stripes on the
leaves.
For control of this disease, use rust resistant variety. Follow crop rotation and adopt mix cropping
pattern.
Avoid excess use of Nitrogen. When symptom observed, do dusting of Sulphur @5-10 kg/acre or take spray
of
Mancozeb @ 2 gm/Ltr or spray the crop with Propiconazole (Tilt) 25 EC @2 ml / litre of water.
Karnal bunt:
It is seed and soil borne disease. Infection occurs at flowering
stage. Cloudy weather
condition
during spike emergence to grain filling stage of crop leads to development of disease. If the rains
occur during
the month of February in north Indian plains (disease-prone areas), the disease is likely to come with
higher
severity.
For control of this disease use karnal bunt resistant varieties. For management of this disease,
take one spray of Propiconazole (Tilt 25 EC) @2ml/ Ltr of water at ear head emergence stage.
HARVESTING
Harvesting of high yielding dwarf variety is carried out when leaves and stem turn yellow and become
fairly dry.
To avoid loss in yield crop should be harvested before it is dead ripe. Timely harvesting is needed for
optimum
quality and consumer acceptance. The right stage for harvesting is when moisture in grain reaches to
25-30%. For
manual harvesting use serrate edge sickles. Combines harvester are also available which can do
harvesting,
threshing and winnowing of wheat crop in single operation.
POST-HARVEST
After manual harvesting, dried crops for three to four days on threshing floor so that moisture content
of grain
comes down to 10-12% and then threshing is done by trampling bullocks or thresher attached to bullocks.
Direct
sun drying and excessive drying should be avoided and the grains should be packed in sound clean gunny
bags to
minimize the losses. The Hapur tekka is a cylindrical rubberized cloth structure supported by bamboo
poles on a
metal tube base, and has a small hole in the bottom through which grain can be removed. Large scale
grain
storage is done in CAP (Cover and Plinth) and silos. To keep away several pest and disease during
storage, use
1% malathion solution for disinfection of gunny bags. Properly clean the storage house, remove the
cracks and
fill the rat burrows with cement. White wash the storage house before storing grains and spray Malathion
50 EC @
3 Ltr/100 Sq. meters. Place the heap of bags 50 cm away from wall and in between the heaps give some
gaps. Also
there should be a gap between the roof and the bags.
