Fodder Crops & Weeds
By Muh Salman Naeem
general speaking, a more intense plant stands in field
allows the crop to compete better with weeds.
After a certain point, however, the benefits of an
increased plant population do not overweight the cost of
additional seed, especially when seed cost is high.
Seeding rates can be used as part of an incorporated
herbicide resistance management plan.
Weed Science Departments are actually working in such
Researchers conducted studies in 2013 and 2014 to
determine the most effective seeding rates when used with or
without pre-emergence herbicides.
With the reduced seeding
rate, fields had fewer crop specific plants and a
slower-to-develop crop canopy, providing weeds a greater
prospect to establish and bloom in the field.
Canopy development, an
important component of integrated weed management, relies on
the growth of the crop.
Through the higher seeding
rate, Crop had a competitive advantage over weeds and closed
canopy earlier, thus reducing weed growth.
Due to increased crop
density, total plant biomass should be increased, which
resulted in higher weed suppression.
High seed rate can also
affect other aspects of crop production just like costly
seeds required high end inputs & managements to get good
production, in cereals, cash crops and forages.
For example hybrid maize
requires more NPK to get high yield ratio to overcome the
effective seed cost.
In forages, yield issues are
not considered foremost and usually crops behave different
in local climate with different approaches.
• In irrigated areas, high
seed rate is considered good to produce good quality fodder
with high digestibility. Plant stem size remains medium due
to dense population in limited area and high in nutrition.
• In rain fed area, high seed
rate is often not recommended due to low available moisture
• Lower seeding rate achieved
beneficial crop yields and economic returns when combined
with a pre and post sowing herbicide.
Narrow row spacing with a higher seed rate can work together
to reduce overall weed competition. Newly developed drill
for very narrow seed plantation at (4-4.5 inches) can
maximize yield of canola, alfalfa and wheat at higher
10 kg seed require for
alfalfa sowing through broadcast method, it can be lower
down to 6 kg through drill method with reduced weeds issues.
Mixed cropping: is
growing of two or more crops simultaneously on the same
piece of land. It is also known as multiple cropping
considered best sowing plan for fodder in Punjab in winter
In winter season, alfalfa and
clover fodder crops are usually mixed with rye grass,
spinach or mustard crop not only to get good production but
on nutritional point of view.
Alfalfa and clover both
belongs from leguminous family having high pretentious
source but grass crops are twice in yield than legume crops
and available in field for long time resistant against
Weeds can be a big issue in
single crop and reduced many folds due to two cropping
two or more crops are grown together, each must have
adequate space to maximize cooperation and minimize
competition between the crops.
Fodder crops like alfalfa and
clover in different fruit orchards are good example of
Fluid irrigation is the
general irrigation method in Pakistan. Its mutual beneficial
cropping for grower and soil in sense of fertility through
legume fodder for orchard and use nutrition’s which are far
aside from fruit plant roots.
