Picking of citrus fruits is done almost throughout the year. The fruit should be picked when it is fully ripe. It will not develop taste or sugar in storage after picking. The best method is to pick the individual fruit by holding it in one hand and cutting the stalk with a knife and collecting it into boxes or baskets to avoid injury to the stem.

Pakistan is blessed with a climate ideally suited to the farming of all kinds of fruits – rich in taste and juicy. Farmers have been developing new varieties of fruit by grafting one exotic variety with other.
Season of Kino in Pakistan starts from December and last till April. Kinnow is very delicious in taste and if treated with proper fungicide and wax and careful handing and storage of Kinnow at about 4 Degree Centigrade can retain it’s freshness until 2 months.
Pakistan is one of the few countries in the world where some of the varieties of fruits grown in cool temperate climate such as apples, pears, plums and cherries while in warm temperate climate such as apricots, grapes, pomegranates and melon and in tropical and subtropical climate such as bananas, mangoes, dates, guava and citrus so the fruits are usually available throughout the year.
Nature has blessed Pakistan with ideal climate for growing a wide range of delicious fruits and large varieties of vegetables. Over the years, Pakistani experts have developed unique stains of exotic fruit varieties unmatched for their rich flavor and taste. From the selection of the finest fruits grown, a reasonable quantity is processed and properly packed for sales and consumption in local market and exporting abroad.
Pakistan exported 268,741 tones of fruits worth US$ 79.83 million during 2000-01, while the export of vegetables stood at $22.50 million. Out of the total exports of fruits and vegetables the share of mangoes was 53,443 tonnes valuing $16.54 million, showing an increase of 43 per cent over the 1999-00.
Agriculture is the main contributor to GDP either directly or indirectly in the form of agro-based industries. The production of fruits and vegetables is not fully utilized and after their domestic consumption a major part is wasted due to lack of infrastructure, storage and processing facilities. The wastage quantity can be utilized by just streamlining and regulating the system from grower to export markets.
Pakistan produces large varieties of mangoes, its production has increased from 908 thousand tonnes in 1995-96 to 937 thousand tonnes in 1999-00. World production of mangoes stood at 19 million tons in 1995, which rose to 23.8 million tonnes in 1999, registering an increase of 24.75 per cent over the five years. Philippines and China have achieved much over 100 per cent increase in mango production during that period. Thailand is another country, which has also registered a significant increase. Rise in Pakistan’s annual mango production during 1995-99 is only 3.4 per cent. Our share in global mango production in 1999 is 3.8 per cent.
Beside mangoes, Pakistani kinoos and apples are also in great demand in the international market. Balochistan produces about 480,000 tones of apples annually but only 3,000 tones were exported last year. About 30 per cent apples wasted every year in Balochistan only. Recently the government has given approval for the establishment of treatment plant in Quetta. While two plants are about to start working in Karachi. It is estimated that after starting of these treatment plants export of apples would be increased to about 20,000 tons per annum. There are good investment opportunities for the private sector to establish processing units near the fruits and vegetable growing areas. This would not only prevent wastage but would also help to earn foreign exchange.
There are also bright prospects for exporting fruit juices and pulps. By establishing modern plants, Pakistan can earn foreign exchange three times more than that being earned by export of fresh fruits and vegetables.
Sunny winters in Pakistan yield a large variety of citrus fruits. The juicy kinno is a unique hybrid of two varieties of California Oranges. It has a soft skin which is easy to peel and has a lovely fragrance.
Pakistan is fortunate in having great diversity in its soil and in its ecological and climatic conditions, ranging from extremely warm to temperate, to very cold. This enables the country to grow many kinds of trees, plants, shrubs, vines and creepers which yield a large variety of fruits and vegetables.
