Wheat is the most important grain and a staple food
for more than one third of the world population. It is sown on 220
million hectares around the world with 564.6 million tons production,
an average of 2500 kg grain per hectare. China sown wheat on around 30
million hectares, followed by the Russian Federation; India, the USA,
Australia, Canada, Turkey and Pakistan. As far as the highest yield is
concerned France in Europe produces 7200 kg per hectare as it has much
longer growing season of winter wheat. It is also a staple food crop
of Pakistan, and accounts for nearly 36 per cent of the total cropped
area, 30 per cent of the value added by major crops and 76 per cent of
the total production of foodgrains. Pakistan made an important
breakthrough last year by not only achieving self-sufficiency in wheat
production, but by also being able to become a wheat exporting
country. Among the wheat producing country, Pakistan stands at 10th
place in terms of area (8.5 million hectares) and 59th in terms of
yield (21.0 m ton) annually. The production of wheat per acre differs
from area to area and farm to farm as some allied and supporting
factors have to be taken into account, while calculating yield.
Weather and the availability of the irrigation water through canals
also contribute to the yield. The average per acre yield of wheat is
estimated between 20 and 25 maunds and above it needs an extra effort
as well as natural supporting factors.
Last year (1999-2000), the area, yield and
production in cases of wheat were the highest ever in Pakistan. Among
the cereals, the wheat is the most vantage and pivotal crop of the
country. This edible food crop accounts for about 37 per cent of the
cropped area of the country. Wheat was sown over in area of 8.5 mha,
recording a 3.6 % increase over the previous year's figures. Yield per
hectare was 2,491 kgs as against 2,170 kgs in the previous year,
representing an improvement of 19.3 %. Production over 21 m tons was
higher by 18 % than when it was in the previous year. The surplus
productions have resulted in the export of wheat to the foreign
countries. The major area of wheat in Pakistan lies in Punjab followed
by Sindh. However, the yield per hectare is slightly higher in Sindh
as compared to Punjab. While, the area under the crop has increased by
2 % in the Punjab and by 9.4 % in the NWFP over the last year, it has
decreased by as much as 30 % in Sindh and by 60 % in Balochistan.
To become self sufficient in wheat, Pakistan has
all the required basic ingredients such as fertile land, sufficient
irrigation water, hard working farmers, certified seed varieties of
local and foreign origin and modern technology in abundance, provided
these are utilized to full potential, which is only possible, if there
is a firm will on the part of the planners. This incentive encouraged
farmers to apply sufficient amounts of diammonium phosphate (DAP) and
urea to the field. Wheat price was raised from Rs. 240 to Rs. 300 for
per 40 kg at the time of sowing the crop. Last year, this timely
measures help the farmers to increase wheat production. At the time of
wheat sowing in Rabi Season Nov-Dec, the government had taken and the
hard work put in by our farmers. All this was the result of certain
measures taken by the government. About 70 per cent of wheat are sown
in irrigated area and 30 per cent in the rain-fed regions. The latest
official estimates indicate that against the target of 20 million tons
for the current year, the production of wheat is touching a record
level of 22 million tons as compared to 17.8 million tons.
Wheat crop demands an urgent need to accelerate its
production in Pakistan either by increasing the area under cultivation
or by enhancing the productivity per unit area through the adoptions
of improved production technology. Wheat crop is grown in large
irrigated and rainfed areas of the country. Pakistan is basically an
agricultural country, where 70 % of the population depends direct and
16 % indirectly in agriculture. To feed a hundred million people,
about four million farmers grow on 8.5 million hectares of wheat every
year, representing 37 %, of the total cropping area. The wheat crop is
beset by a variety of problems, reducing the yield to a national
average of 1.6 t/ha. The most intractable of all the problems
affecting wheat is that of weeds. As many as 37 species of harmful
weeds grow in wheat field in different cropping systems, the most
troublesome being Phalaris minor, Chenopodium album, Convolvulus
arvensis, etc. Using a 30 % growth rate, the population of
Pakistan increases by 2 million each year. By the year 2005, the
population of Pakistan will reach about 160 million. The situation
depends on huge quantity of wheat grain to feed the population. The
development of improved variety with high yield, good quantity and
wide adaptation will fulfil the requirements and uniform the
socio-economic conditions of the country in ground and forming
community in particular.
Southern Punjab had excelled in wheat production
last year, but the crop is now reported to be languishing in the
region. The officials concerned concede that the crop in southern
Punjab where output had averaged between 30 and 60 maunds per acre has
not been given even the first watering from the country's irrigation
system. There is no way of striving the damage done to the wheat in
the field. Farmers are complaining of slanted growth of plants, they
have not risen beyond 12 inches to a maximum of 18 inches in most
cases and the message is a substantially scuttled yield per acre.
Punjab heavily relies on the use of groundwater for meeting irrigation
requirements of crops, but groundwater is largely brackish and need to
be mixed with canal water for sustaining productivity. In the absence
of canal water, tube-wells have mostly not been commissioned, because
of high electricity charges are another discouraging factor for the
common farmers. There was a strong case for increasing the price of
wheat of the mounting inflation and constantly rising cost of inputs.
All this adds to the woes and agonies of the farmers who had responded
to well last year to the incentive with a record produce of wheat
crop.
The water crisis was looming frighteningly large
across the country and planning should have been undertaken at the
start of the wheat cultivation season. That may have helped to avoid
the problems, that now seems certain to severely hit the crop. Last
year, the country produced a bumper crop of 21.7 million tons and
managed to provide the staple food to the populace for the first time
in many years, resorting to imports. The domestic consumption is about
18 million tons of wheat. This target seems to be well within the
reach due to support price mechanism introduced by the government to
evolve internet of the growers in certain crops. Even the stashed
target of 20 million tons of wheat would be enough to eater to the
need of the country. However, all such exit exports from where wheat
is smuggled out into Afghanistan, Iran and Central Asian states would
be required to ground to plug the leakage.
Punjab was expecting a total wheat production of
14.23 million tons, Sindh 2 million tons and NWFP and Balochistan 0.73
million tons and 0.5 tons, respectively. There are only two ways to
increase wheat production increased acreage and/or increased per
hectare yield. Though wheat acreage production and per hectare yield
have increased from 1990-91 to 1999-2000, it has grown at very smaller
rate compared to the increase in population. While, the wheat acreage,
production and per hectare yield has risen during the previous decade,
but they were unable to match the substantial increase in population.
To break the stagnation in the agriculture sector
for the production of crops, the huge water losses in the irrigation
system should be checked, the infrastructure in the rural areas to be
developed to improve farm to market delivery and proper education and
training to acquaint the farmers in modern agriculture practices are
required. Devoted and concerted efforts associated with scientific
approach are needed to make each province and only self sufficient in
food but producing export surplus to give a strong helping hand to the
national economy. In addition, following factors are suitable for
increasing wheat production:
i) Prior to sowing, wheat fields must be
well levelled and cleared from previous plant debris and weeds.
ii) Seed of high yielding wheat varieties
resistant to rusts, smuts, etc. be sown in sufficient amount.
iii) Seed treatment with a suitable
insecticide should be carried out carefully.
iv) Timely sowing is an important factor.
This phenomenon will help in good seed germination, and ultimately
will improve the yield productivity.
v) Timely application of nitrogen-phosphotic
fertilizers will be carried out.
vi) Weeds being the main robbers of plant
food from soil, space and even light required for wheat plants, be
controlled by cultural practices and in case of heavy infestation, may
be eliminated by application of herbicides, weedicides. This technique
will definitely increase yield.
vii) Care must be taken to check the pre-
and post-harvest losses of wheat. Pre-harvest damage may be checked
from attack of birds, astray animals around the villages and wheat
fields. Post-harvest losses must be checked from the attack of rodents
and other insect pests and fungi. After proper trashing, wheat grains
should be placed under hygienic conditions in fields and godowns as
well. Uses of powdered neem leaves in the bags of wheat grains will
also seemed to be useful. It is a traditional treatment for
preservation of cereal grains.
