Onion is an important bulb vegetable crop, commercially grown in many countries of the world including Pakistan. Onion is being used as a raw and given protection to human beings from sun stroke, normally is consumed green as well as in mature stages almost by everyone (poor as well as rich people), by different mean.

Onion (Allium cepa L) is one of the important ingredients used in daily meals all over Pakistan. Onions are used in soups, salads, sauces and for seasoning foods. Onions as a part of diet may play a part in preventing heart disease and other ailments (suggested by medical research). It is rich in phosphorus, calcium and carbohydrates.

The green leaves and immature and mature bulbs are eaten raw or used in preparation of vegetables. Onions are used in soups, sauces and for seasoning foods. The small bulbs one pickled in vinegar. Recent research has suggested that onions in the diet may play a part in preventing heart disease and other ailments. Onion bulb is rich in phosphorus, calcium and carbohydrates. The pungency in onion is due to a volatile oil known as allyl-propyl disulphide.
Onion is an important crop all over the world. In Pakistan, the major growing areas are Kasur, Gujranwala, Sheikhupura, Vehari, Khaniwal, D.G. Khan, and Jhang in Punjab, Hyderabad, Mirpurkhas, Sanghar, Sukkar, Naushero Feroze and Badin in Sindh, Swat in Khyber Pakhtunkhwa (NWFP) and Mastung, Kalat, Chagi, Khuzdar and Turbat in Baluchistan. More than 50 percent of the total production comes from seven districts, namely, Hyderabad, Mirpurkhas, Sanghar, Swat, Mastung, Kalat and Turbat.

Present Status and Future Prospects of Onion in Pakistan
Introduction
The cultivated onion (Allium cepa L.) is one of the important condiments widely used in all households. The total world production of onion was about 86.34 million tonnes and Pakistan occupied 8th position with 2.25% share in production (FAOSTAT, 2011). Leading onion producing countries with share in production were China (28.68%), India (18.45%), USA (3.89%), Iran (2.90%), Egypt (2.66), Turkey (2.48%), Russian Federation (2.46%) and Pakistan (2.25%) (Table1). It was estimated that the value of the world production of dry onion approached 29490 million US $ during 2011. More than 90% of onion is consumed within the countries of production. However, the crop is a major export earner for some economies.
There are several uses for onions including, pickling, chutney, sauces and dehydration. Onion bulbs are consumed both cooked and uncooked. In addition the common onion is also an important salad crop when eaten green (scallions). Particular varieties have been developed for most of these purposes. Cultivars for dehydration have a higher bulb dry matter (17-20%) than the typical (10-12%). Bulbs for consumption uncooked are sweet, mild-flavored and large; with single centers suitable for making onion “rings”. Recent research has suggested that onions in the diet may play a part in preventing heat stroke, disease and other ailments. Onion bulb is rich in phosphorus, calcium and carbohydrates. The pungency in onion is due to a volatile oil known as allyl-propyl disulphide.

Pakistan has to strive hard to enlarge its share in the existing markets and penetrate into the new markets. It should be kept in mind that our competitors especially India are better organized in terms of product quality, consistent supplies, logistics and market promotion. Malaysia imported onion about 454,000 tonnes, Saudi Arabia 323,000 tonnes, Bangladesh 268,000 tonnes, Sri Lanka 178,000 tonnes and UAE 175,000 tonnes during 2011. Pakistan can substantially increase its share in these markets. In addition, Pakistan has established a foothold in Russian Federation by exporting kinnow and its exports are constantly increasing. During this period, Russian Federation imported about 453,000 tonnes onion. Pakistan can have a reasonable market share by using existing business connections.

Pakistan Onion Production
Pakistan produced about 1.94 million tonnes of onion during 2011. The average yield of onion in the country is 13.6 t/ha which is rather low and could be attributed to poor planting densities, low use of fertilizer, weed infestation and use of inferior quality seed. Lack of plant protection measures further aggravates the situation in lowering yields and depressing quality. Though subjected to annual variations, overall area and production of onions in Pakistan have shown an increasing trend during the past 10 years (Table 4). The good onion crop and reasonable market prices helped the private sector export almost 173000 tonnes in 2011.

Pakistan Onion Exports
Generally speaking annual export of onion from the country averaged about 47,474 tons during 2005 to 2010. Yearly exports are given in Table 7. The lowest export figure in 2006/07 is attributed to bad crop harvest pushing prices upward in the domestic market and rendering exports uneconomical. In 2011 Pakistan exported 173000 tonnes of onions.

Per unit export prices are also low which apparently are attributed to produce quality. Onions for export are sourced from the wholesale market, manually graded and repacked according to the choice of exporters and generally shipped through non-reefer open top containers. The repeated and rough handling, extended time between harvesting and product preparation for export and holding produce under undesirable conditions tend to adversely impact the produce quality and as a consequence its market ability and sale price. The destination-wise exports of onion are given in Table 8.

UAE, Malaysia and Sri Lanka are the main markets for onion exports from Pakistan. These markets are very convenient and Pakistan has the potential to increase market share. There is need to consolidate position in the existing markets especially UAE, Sri Lanka and Malaysia through market promotion and consistently supplying quality produce, and also identify new markets.
Growing Areas
Onion in Punjab is mainly produced in Southern part comprising of Khanewal, Vehari, Okara, D. G. Khan, Bahawalpur and Rahimyar Khan districts. Ghotki, Nausherhro Feroze, Nawabshah, Shikarpur, Sanghar, Mirpur Khas and Hyderabad are main onion producing district in Sindh. Similarly Swat and Dir in KPK and Mastung, Kalat and Chagai are main onion producing districts in Baluchistan.

Varieties
Onions start bulb formation when the day length is of the proper duration and different varieties of onions require different day lengths to initiate bulbing. In general, most common varieties fall into one of two classes, long-day (for northern latitudes) and short-day (for southern latitudes). For this reason, onion varieties that are grown in the South are not adaptable to the North and vice-verse. Onion varieties grown in Pakistan are given in Table 9.

Punjab Desi Red, Phulkara
Baluchistan Sarriab Surkh, Chiltan-89

Planting and Harvesting Seasons
The agro-ecological diversity obtained in the country enables production of onions almost around the year (Table 10). However, production volumes greatly differ from crop to crop as follows:
 June-July Punjab & Khyber Pakhtoon Khawa Plains (13%)
 August-September Khyber Pakhtoon Khawa Uplands (16%)
 August-October Baluchistan (26%)
 November-May Sindh (45%)
It is apparent from the above that bulk of the onion crop is harvested from August to May. The augmented supplies tend to keep prices in the domestic market low thereby offering an opportunity for export. Therefore, onion exports are mainly undertaken during this period, predominantly from Sindh crop. Due to limited shelf life and absence of suitable cold storage facilities in the country, onions have to be disposed in the domestic and international market as fresh harvest.

Current National Problems
 Identification of suitable varieties for short to intermediate days, high yield with better storage quality.
 Inadequate supply of good quality seed
 Hoeing and weeding for control of weeds in onion crop is very expensive.
 Considerable damage is done to onion crop by thrips, purple blotch and downy mildew.
 Phosphorus and potash fertilizers are rarely used by the farmers. As a result the bulbs have very poor storage quality.
 Marketing of surplus produce of onion during the year of over production is a great problem.

Climatic Requirements
Onion is a cool season plant, its optimum temperature for seed germination ranges from 20-25 °C, early growth stages before bulking require 13 to 20 °C and bulb development needs 16 to 25 °C. Best growth and quality is obtained the temperature is cool during the early development and warm near maturity. A dry atmosphere at harvest is desirable to obtain satisfactory curing of the bulbs. The onion is fairly resistant to frost injury, but not immune. At low temperature, bulbing takes place very slowly and if the temperature is very low, no bulbing takes place. At low temperature onions are more inclined to run to seed called bolting.
