2. Wheat
Technical Name;
Triticum aestivum
Origin and
History;
First grew in the
Middle East,
One of the first
plants cultivated
about 11,000
years ago.
4,000 B.C. wheat
farming spread to
Asia, Europe and
North
Africa
In 1834, Cyrus
McCormick, an
American
invented a
reaping
machine.
In 1834, a
threshing
machine
was also
invented

5. Weed
Undesirable plant in the field..
Global basis 35% cro loss
3% crop loss is due to weeds ..
Also effect the quality of wheat
..
Act as a causative agent of
disease..
Loss of water and fertilizer ..
6. Weed control measures..
Weeds may be controlled in cropland through cultural, mechanical and chemical means.
Judicious use of these methods individually or in combination can effectively manage weeds
without causing economic loss or environmental harm. Selecting the proper management
strategy depends largely on the target weed(s) and the infestation level.
The type of crop will also play a major role in determining the timing of mechanical measures.
• Use weed-free seed to protect against weed infestations in the row and the introduction of new
weed species.
• Thoroughly clean harvesting equipment before moving from one field to the next, or require
custom harvesters to clean their equipment before entering the field.
• In conventional tillage systems, use mechanical tillage or preplant burndown herbicides to
remove initial weed flushes before planting. This will reduce or eliminate the potential for continued
infestation.
• Use of Bar harrow in early 30-40 days.
• Due to burning of crop residues seed of weeds are destroyed ..
• Don’t fed to animals
• Germination rate must be 85% if we use 5-10% seeds more than recomended seed rate then weed
growing rate is less.
7. • Rotate crops that physically outcompete certain weeds, resulting in their gradual decline.
Remove light or spotty infestations of weeds by hand hoeing or spot cultivation to prevent weed
seed production and the spread of rhizomes or roots. When plowing perennial weeds, take care
to prevent the transport and spread of plant parts to other areas of the field.
• Employ integrated weed management strategies. Use herbicides only when necessary, and
combine their use with mechanical, cultural or biological methods.
• Rotate or mix herbicides with different modes of action. If possible, rotate crops where
herbicide rotations are feasible.
• Scout fields regularly for resistant weed populations, and control the weed escapes (treat them
as you would a newly established invasive species).
• Plant weed-free wheat seed.
• Clean tillage and harvest equipment to prevent the spread of resistant species.
• Use of Daab method in early and mid sowing
• Use of fertilizer ,water ,weedicides on time
14. Sowing Time
Early Sowing 25 Oct – 10 Nov
Mid Sowing 10 Nov – 30 No
Late Sowing Upto 15 December
15. Land Preparation
Land Preparation
Cultivate the fallow land 4-5 times before sowing
Use land leveler if required
Split the field into small portions before rouni water
After rouni water at wattar conditions, use planker to preserve moisture
Use “Dab method” in early and mid season cultivation of wheat to control weeds.
If possible zero tillage method is used
16. Use of Quality Seed
Certified seed. (Punjab Seed Corporation)
Graded Seed (Through seed graders.)
Seed Rate
50 Kg. – 15th November.
60 Kg. – 16th to 15th December
