CROP
PRODUCTION
Agriculture and Crops
• Growing plants and
receiving animals for
food , clothing, and
other useful products
is called agriculture.
• Plants of same kind
grown on a large scale
for food, clothing, etc.,
are called crops.
Agricultural practices
1)Soil preparation
2)Selection and sowing of seeds
3)Irrigation
4)Weeding
5)Crop protection
5)Harvesting
6)Threshing
7)Storage
Selecting good-quality, healthy seeds
is the next important step of crop
production. There is a simple method
to select healthy seeds. Put the seeds
in water. The seeds that floats should
be removed as they are unhealthy
seeds. Others are the healthy ones.
Sowing is the process of
placing seeds in the soil.
Sowing may be done
manually or with the
help of seed drill.
This process involves directly
sprinkling seeds into the soil.
Seeds sown in this manner are
distributed unevenly, Also, this
method may not ensure that all
seeds are sown at the correct
depth.
A seed drill ca be pulled across
the field using bullocks or a
tractor. Seeds sown using a seed
drill are distributed evenly and
Placed at the correct depth in
the soil.
IRRIGATON refers to providing
water to the crops.
Methods of irrigation may be
considered under two broad
categories :
1)Traditional
2) Modern
TRADITIONAL METHODS
• Traditional methods of
irrigation are cheaper , but
often lead to wastage of
water.
• EG- Canal irrigation , furrow
irrigation , chain pump , moat
[ pulley system ] , dhekli ,
rahat
MODERN METHODS
Modern methods of
irrigation don’t require much
physical energy and also
saving water.
E.g.- Sprinkler irrigation and
drip irrigation
WATER LOGGING
• Care must be taken not to water the field
excessively. Excess water on the field may
cause a condition water logging.
• It decreases the amount of air available to
the roots.
• It leads to an increase in the salt content of
the soil.
WEEDING
• Sometimes , undesirable plants called weeds
grow along with the main crop.
• E.g.- Amaranthus , wild oat ,grass
• The process of removing weeds is called
wedding.
• Weeding may be done manually or by using
chemicals called weedicides.
Manual weeding
Weeds may be uprooted by hand or removed with the help of
implements such as harrow, trowel, or hoe
Manual weeding has the following disadvantages.
• It is time consuming and may even lead to accidental removal
of desired crops.
• The implements used (such as trowel, harrow, and hoe) are
made of iron and need regular maintenance to prevent rusting.
Using weedicides
A weedicide is a chemical that is used to destroy weeds.
Weedicides destroy the weeds without affecting the crop.
Dalapon, metachlor, and siziazine are examples of
weedicides.
Harvested grains need to be stored
before they made available for
consumption . The storage area should
be kept clean and dry .Pesticides should
be sprayed beforehand to keep away
pests.
The process of cutting
and gathering of seed is
called harvesting.
Threshing the process of
separation of the grain from
chaff (seed covering and
tiny pieces of leaves or
stem)
Grass crop
Mustard
Small grain
Growing different crops in a field according
to the season is called crop rotation.
