In
this world, man has achieved numerous things by manipulating
and controlling space and time.
However, man will continue to utilize agriculture
for food, clothing, shelter and medicines with added
sophistication in the environmental in the context
of 21st century. During the second half of 20th century,
significant and far-reaching developments have made
in the philosophy and methodology of crop improvement,
contemporary agronomy and food sciences. The technology
which has made most significant contribution to mankind
is the technique and methodology of plant breeding,
which is indeed an evolutionary process. Our present
day crop plants are the products of evolution. In
recent years, technological innovations in genetics
and related disciplines have made it possible to direct
this evolution by utilizing hybridization, heterosis,
polyploidy, mutations, wild crosses, tissue culture,
haploidy, protoplast fusion, soma-clonal variation,
antibody probes and DNA probes.

Pakistan
is essentially an agricultural country. Similar
is the case in most of the under developed, where
the food and agriculture sector is the principal
contributor to the gross domestic product. Nonetheless,
it is lamentable fact, that two-thirds of mankind
comprising the developing nations produce a mere
one-fifth of the worlds food supply. Lack
of self-sufficiency in food production in the
these countries with ever increasing population
pressures has rightly been described as a time
bomb with which humanity is precariously co-existing.
The reasons for the poor performance of under
developing countries in agriculture are lack of
organization, inadequate economic returns to the
farmers, dearth of necessary inputs and above
all a minimal use of science and technology in
farming, harvesting and post-harvesting.
One of the finest Pakistani success of post independence
era has been the Green Revolution of sites through
the users of Mexi-Pak wheat and IRRI rice varieties,
which turned the country from a chronic importer
of food-grains into an exporter of some essential
food items. Green Revolution has been instrumental
in significant enhancement of productivity in
Pakistan, particularly in wheat and rice. |
|
|
The newly developed early
maturing and high yielding dwarf varieties of wheat
and rice during that period (1960), helped in increasing
the production of food-grains significantly. This has
successfully led to massive transformation in the rural
and agrarian economy, which came about through the collaborative
efforts of farmers, agriculturists, researchers, planners,
backed up with necessary administrative and political
supports. Since independence to 1947, while the population
increased almost supernumerary times, and food grains
production also increased many times. From a mere million
ton during 1960-65, food grain production increased
to an estimated many thousands million tons in 1998-99
and productivity increased from 500 kg/ha to more than
2500 kg/ha of cereal crops.
Besides Green Revolution, significant production advances
have been made in sugar, milk, fish, oilseeds, fruits,
and vegetables. There are different research organizations
in the country who have been actively engaged in research
work for better production of food grain crops. The
major cereals grown in Pakistan are wheat, rice an maize.
Wheat breeders in Pakistan have developed over 50 varieties
for irrigated and rain-fed conditions in different parts
of the country and for different sowing timings. This
includes large number of varieties, which are resistant
against various wheat diseases. As a result of these
efforts, wheat production |
 |
in the
country increased 10 folds after independence.
Wheat, the main staple food of people, is the
single-largest grain crop of the country For the
current year (2000-2001), the target of the area
and production was fixed at 8.50 million hectares
and 2.2. million tons, respectively. The average
production of wheat has increased from 9.5. million
from in 1975-80 to 20.0 million tones in 1999-00,
the quantum jump in wheat production was mainly
due to the introduction of high yielding and disease-resistant
varieties, adaptation of improved crop production
technologies and proper plant protection measures
and some increase in area of the crop.
Rice. It is the major food
as well as commercial crop of the country. Rice
is the second most important cereal crop in Pakistan.
It occupies about 10% of the total cropped area
of the country. On an average, one-third of its
production is exported every. Production of rice
has increased from 0.9million tons to 1975-80
in about 5.0 million tons in 1998-99. In the current
year, rice was planted on an area of 2125 thousand
hectares and the production is estimated at 5.5
million tons. Outstanding achievements to rice
improvement after independence included development
of high yielding rice varieties of local and basmati
for irrigated areas. |
|
| Our projected requirement
of rice in 2005 AD is 6.0 million tones against the
present production of 5.0 million tons and the different
research organization in the country is on its way to
developing higher yielders with built in resistance
to stresses (biotic and abiotic) with). With the advent
of the Green Revolution, the semi dwarf varieties IR8
and IR6 were introduced from the International Rice
Research Institute, Philippines, in 1967 and 1969, respectively.
The area and production of rice have increased by leaps
and bounds in Pakistan. However, in spite of this phenomenon
progress, Pakistan still ranks only No. 10 in total
rice production among the 14 rice producing countries
of the world. |
 |
Maize.
It is the third cereal crop of the country. The
production of maize has increased with an average
growth rate of 3.3% from 0.81 million tons in
1975 to 1.2 million tons in 1993. Research establishments
are trying their best to grow maize to the maximum
quantity by adopting new techniques suitable for
this crop to a large extent.
Sugarcane. Is an important industrial
crop and covers about 5% of the total area of
the country. It serves as major raw material for
the production of white sugar and gur. Sugarcane
has been cultivated on an area of about 1000 thousand
hectares in the current year and production has
been estimated as more than 50000 thousand tons.
Attractive support price of cane and good weather
conditions in Punjab and Sindh have helped to
bring about improvement in its production. Over
the last 40 years, sugarcane has increased by
3% annually. This increase is mainly due to increase
in the areas and adaptation of the technologies
increase is mainly due to increase in the areas
and adaptation of the technologies, which went
up from 756 thousand hectares in 1975-80 and to
more than 1000 thousand hectares to 1998-99. |

Oilseeds
crops. The oilseed crops included-repeseed,
mustard, groundnut, sesamum, linseed, soybean,
sunflower and sufflower. There is serious shortage
of edible oils in Pakistan which started developing
soon after independence and continued to worsen.
Edible oil is essential for human life. Pakistan
is endowed with congenial atmosphere to grow all
the conventional (rapeseed, mustard, groundnut
and sesame) and non-conventional (soybean, sunflower
and safflower) oilseed crops. However, about 65%
of the domestic edible oil has been increased
substantially, but still there is serious shortage
of these crops. The country has to import huge
amount of palm oil and soybean from foreign countries
to support the burgeoning population.
Cotton. It is an important cash
crop of the country. It supplies cash return to
farmers, supplies raw material to the textile
industry and provides employment in both the rural
and the urban areas. It is sown in 3 million hectares
and covering 12% of the total cropped areas. It
earns a lot in foreign exchange through he export
of raw cotton, garments and threads etc. |
|
|
Many high yielding cotton varieties
has been released in the country which have changed
the economical condition of the country. Environmentally
sound, easily adaptable and economically viable integrated
pest management strategic have been developed for pest
control in major crops such as cotton, rice, wheat,
sugarcane, oilseed crops, and pulses. These strategies
are expected to reduce the pesticide consumption in
these crops by almost 50%.
Pulses. The pulses include gram, lentil, mung
and mash. Pulses are the essential component of human
diet and are the major source of vegetable protein and
amino acids. These crops are generally grown under rainfed
conditions on marginal lands. Pulses are grown all over
the country, Ecologically, there three zones for cultivation
of pulses northern with 60% rainfall. The central
region is highly fertile while, southern tract. Pulses
are grown under both irrigation and rain-fed conditions. |
Fruits.
The major fruits grown in the country
are: citrus, mango, dates, apple, banana, guava,
apricot, peach, pear, plus, grapes, almond, pomegranate
and many others. The production of fruits have
been increased due to the result of massive research
support to the horticulture industry. Adoption
of tissue culture and drip irrigation technology
in banana has led to marked improvements in productivity.
At present Pakistan has a prominent place in the
production of fruits in the world. Research on
post harvest management in fruits and vegetables
has led to development of many technologies including
low cost environment friendly cool chambers for
on farm storage of fruits and vegetables. Ventilated
CFB packing for mango, citrus, apple etc. long
distance transportation for mango for export,
raw mango peeler are some of the other significant
achievements. For export promotion and value addition,
varietal screening has been intensified in the
recent years. Mango varieties well suited for
canned slices and tinned juice, grape, varieties
for raisin making have been identified.
Vegetable. Pakistan having a wide
climatic diversity, offers opportunities of growing
almost all kinds of vegetable crops in its different
ecological zones. These are held in high esteem
because of their special attributes and high cash
value, more productivity and high nutritional
quality. Onion, potato, chilli and |
|
|
Garlic are the main vegetables
grown in the country. Development of hybrid seeds in
vegetables has led to significant production advances
and raising farmers income. In, mushroom, temperature
tolerant species has been developed leading to tremendous
increase in the production of mushroom in the country.
Livestock. In the livestock sector, production of suitable
cross-breds of cattle and their wide adoption has greatly
contributed to the countrys milk production. Some
of the breed such as Nili-Ravi, Kundi Red-Sindhi, Sahiwal
etc. are of high quality animals in terms of milk production
in the country. Pakistan has emerged as a major producer
of animal vaccines and various animal based raw materials
for industrial importance. In Pakistan poultry industry
is growing very fast both for eggs and broilers by application
of genetic improvement techniques and adoption of modern
management practices of poultry. The poultry industry
is helping to reduce the shortage of halal meet in the
country.
Generation of new technology in the fisheries sector
has enabled the country to usher in Blue Revolution
with production levels touching many million tons annually.
Composite fish culture has revolutionized inland fisheries.
There has been a credible increase in prawn farming.
Resources are engaged in identifying, collecting and
conserving the countrys animal and fish genetic
resources.

| Agriculture in modern times requires
appropriate machinery for ensuring timely field operations
and effective application of various inputs as also
for agro-processing. To provide durable solutions to
the major problems faced by food and agriculture sector,
we have concentrated on synergetic approaches involving
new botany, new genetic and uclear technique for the
genetic improvement of most important agricultural crops.
Although, application of modern technologies have resulted
in manifold increase in the agricultural production
in the country, but the situation in far away from ensuring
a complete household food and nutritional security.
The country has millions of small and marginal farmers
in whose farm, the productivity is very low. Science
and technology must be suited to the particular region.
There are wide gaps both in yields obtained against
the potential and technology transfer is very weak.
The concerns of environmental protection, sustainability,
employment, equity, energy, profitability and exports
have become important. To propel Pakistani agriculture
into 21st century, the quality technical skills and
management of agricultural manpower must improve, for
making the research need-based, effective, efficient
and relevant. So, the maximum common good is quickly
possible with least cost. |
