Due to lack of advanced production technology of vegetables, farmers are limited to grow seasonal vegetables and are dependent on marketing mechanism of demand and supply so could not get good prices to sustain vegetable business.

Due to presence of negligible number of vegetable processors and lack of cold storage infrastructure, farmers could not get the reasonable profit margins by selling their produce at the time when market is flooded with seasonal vegetables.

Summer vegetables are susceptible to insects, pests and diseases that can be grown in winter by marinating the temperature through well established production technology of vegetable tunnel farming. The tunnel construction offers maximum crop yield, better maintenance of the fertility of land, controlled temperature and humidity, protection from wild animals and insects and better water conservation.

Mostly tunnels are of three types by their structure i. e. low tunnel, walk-in tunnel and high tunnel.

The off-season vegetable project using high tunnel technology on area of 9 acres needs a capital investment estimated at Rs. 6. 6 million for construction, purchasing machinery and equipment. In addition to this, a sum of Rs. 0. 3 million is required as working capital, which would be used for purchasing of seeds, fertilizers and pesticides etc. The total project cost is estimated at Rs. 7 million 2 1. Introduction To grow vegetables in unfavorable weather conditions is called “growing off-season vegetables”. Human nature ever wishes to get those things that are scarce.

Off-season vegetables and fruits are sold at high prices in the market. Vegetables are rich source of vitamins, carbohydrates, salts and proteins. High population growth rate has given rise to high demand in basic dietary vegetables. Increased health awareness, high population growth rate, changing dietary patterns of increasingly affluent middle class and availability of packaged vegetables, has therefore generated a year round high demand for vegetables in the country in general and in major city centers in particular.

However, our farmers have yet not been able to get benefited from this opportunity and still using traditional methods. In the absence of storage infrastructure and vegetable processing industry in the country, off-season vegetables farming is the only viable option that can add value to the farmers produce. 2. Project Cost By using high tunnel technology many off-season vegetables like tomatoes, cucumber, brinjal, hot pepper, sweet peppers and watermelon can be cultivated. This project is focused on the study of three crops only i. . Tomato, Capsicum and Cucumber, cultivated on area of 9 acres. The land utilized for cultivation is recommended to be leased. The off-season vegetable project using high tunnel technology on area of 9 acres needs a capital investment estimated at Rs. 6. 64 million for construction, purchasing machinery and equipment. In addition to this, a sum of Rs. 0. 3 million is required as working capital, which would be used for purchasing of seeds, fertilizers and pesticides etc. The total project cost is estimated at Rs. 6. 4 million. The estimated yield potential of the farm varies according to the selected type of vegetable. For this project, three proposed vegetables are selected which are listed below. For this vegetable crop mix, it is estimated that a 9-acre farm unit will yield a total of 210,000 kg vegetable per annum. Table 1: Total Production Capacity Vegetables Area (Acres) Production Quantity in (kg)/ Acre Cucumber Capsicum Tomatoes 3 3 3 28,000 18,000 24,000 Total Production Quantity 84,000 54,000 72,000 3 3. Export Prospects

Pakistan is not yet exporting vegetables due to their perishable nature, although there is huge demand in international market. The facility of growing off-season vegetables also allows for growing non-conventional varieties and vegetables, which are in high demand in Europe, Middle East and Far Eastern countries. 4. Production Sequence of Cultivation Production sequence considering the tomato crop is as follows: a. b. c. d. e. f. g. h. i. j. k. Selection of fertile soil for construction of tunnels. Production technology should be adopted through trained persons.

Selection of good quality soil and sowing of seeds for nursery. Preparation of seedbeds in the field for cultivation of vegetables. Using fertilizer of different varieties for the smooth growth of plantation (Recommended fertilizers for different crops). Transplantation of nursery in the soil. Irrigate the soil to maintain the soil moisture. Drip irrigation is more economical. Use of pesticides/fungicides to protect the plants from insects and diseases. Harvesting at proper time as per requirement of the plantation.

Grading of crop on the basis of quality standards. Transportation to the sale points in local or export markets after application of post harvest technology. 5. Suitable Vegetables for Cultivation Growing of vegetables in tunnels under plastic can give superior yields and early spring production. Following crops are high value vegetables and have shown significant increase in earliness: ? ? ? ? ? ? ? ? Cucumber Capsicum Tomato Pepper Bitter Gourds Melons Brinjal Water melon Vegetables can be grown in tunnels in all tropical and subtropical regions of the country.

This technology can successfully be adopted in coastal districts of Sindh which have favorable conditions for off-season vegetable farming. The tunnel farming in districts Thatta, Badin and Hyderabad can reduce the production costs. 4 6. Nutrient Requirements Appropriate quality and quantity of fertilizer plays a great role in the production and quality of vegetables.

In spite of macronutrients, micronutrients i. e. Fe, Zn, Mn, B are also required to increase the yields of crops. These micronutrients are available in the market in liquid and solid forms. 5 7.

Sowing and Transplanting Period of Off-season Vegetables Following are the sowing and transplanting period of selected off-season vegetables with “plant to plant” and “row to row” distance: Table 4: Sowing period for the selected off-season vegetables Vegetables Sowing Transplanting Direct Plant to Period Nursery Sowing Plant Nursery Distance 1-15 Oct 1-15 Nov 30 cm Tomatoes 15-31 Oct 30 cm Cucumber 1-15 Oct 1-15 Nov After mid 50 cm Capsicum Jan Sweet Pepper 1-15 Oct 1-15 Nov After mid 30 cm Jan After mid 25 cm Chappan Jan Kadu After mid 30 cm Bitter Gourds Jan After mid 50 cm Halwa Kadu Jan Ghyia Toori After mid 50 cm Jan

Irrigation In severe summer irrigation to vegetables is required after every 5 – 7 days depending on the type of soil, whereas in December, January light water is required after 15-21 days. The quantity of water can be changed keeping in mind the climatic conditions.

In water shortage areas the best way of irrigation is drip irrigation. Drip irrigation improves the water use efficiency if fertilizers are applied though drips as fertigation and offers more splits of fertilizers, even micronutrients can be used, through the initial growth periods. 6 The benefits of fertigation are in terms of increase in yield, quality of fruit and insect pest control. The best water for irrigation is canal water but if tube well is available then before irrigation or star of business, the water analysis must be done avoiding deteriorative effects if unfit for irrigation.

It is not recommended to make investments of vegetable tunnel farming in saline soils and unfit water conditions. Drip irrigation is a technical matter which can be applied through trained technicians. 9. Types of Tunnels Off-season Vegetable farming in tunnels is gaining popularity because of low cost and easy usage. Plastic tunnels are transparent which provides required sunshine to the plants, and the plastic also plays a barrier against the cool air in winter. Tunnels help to gain maximum crop yield, to maintain the fertility of land and control on temperature. Following are three main types of tunnels:- i) Low Tunnel

Low tunnels are less expensive as compared with the High tunnels but crop yield is low. Soil preparation, spraying and picking is difficult is this tunnel. Cucumber, melons, watermelons, bitter gourds, squashes, and snake gourds etc can be grown in these tunnels. ii) Walk-in Tunnels These are lower in height as compared with High tunnels. Walk-in-tunnels provide high yield compared to Low tunnels. The tunnel is suitable for growing tomatoes, cucumbers, sweet pepper and hot pepper. 7 iii) High Tunnel High tunnels give maximum yield of crops and make easy soil preparation, picking, spraying due to its width and height.

The tunnel is suitable for growing tomatoes, cucumbers and sweet peppers. Table 6: High Tunnel Dimensions Mild steel, zinc galvanized Diameter 40mm Thickness 1. 6 mm Length 20-25 ft 0. 10 mm thick and 20 ft wide Center 10 ft, Sides 6. 5 ft 30 ft 190 ft 6 per acre Pipe material Material Specification Plastic Height Width Length No. of tunnels Tunnel Specification The cost of such tunnel amount to Rs. 95,450 excluding the cost related to plastic used as a shield (Cover) and mulch. 8 a) Support Structure This tunnel is built by pipe material of 40-mm diameter 20-25 feet length.

The tunnel will be 10 feet high from the centre and 6. 5 feet high from the sides. Each tunnel structure will then be covered by 0. 1 mm thick and 20 feet wide plastic sheet. Approximately 6 tunnels can be constructed on an acre of land. Each tunnel will be 190 feet long, 10 feet high and 30 feet wide. b) Seed Recommendations Hybrid seeds are produced through a special process and give crop yield 3 to 4 times more than ordinary seeds. F1 hybrid seeds are recommended for cultivation in tunnels because they have the ability to resist multiple diseases and have above 90% germination capacity as compared to that of ordinary one. ) Important Points for Tunnel Farming ? ? ? ? ? Prior to start off-season vegetable farming in tunnels, the investor must have practical knowledge about farming. Soil and water quality should be tested before starting the farming. Self-pollinated plant should be grown. Recommended seed should be used. Farmer must have the updated market information to earn high profit. 9 10. Suitable Site for Tunnel Farming The purchased land is recommended for tunnel farming but can also be taken on lease. Rural areas around the major cities of the country are the suitable areas for setting up tunnels. ) Preparation of Soil & Sowing ? ? ? ? ? ? Soil should be properly leveled preferably by laser leveling. Preparation of soil with rotaveter/ cultivator. Application of well-decomposed Farm Yard Manure at least 10 ton per acre at least 90 days before sowing. Prepare beds before sowing. Make holes and prepare media mixed with loam soil, FYM and fertilizers to fill the holes at the time of sowing/ seeding. Field should not be flooded with water. Irrigation should be applied in such a way that water level be kept below the seeding place; only moisture reach the seed to wet it for germination.

In this way the percent germination would be more. Keeping in mind the type of soil, light irrigation should be repeated after 2-3 days to assure the proper moistures for germination. ? ii) Expected Production Expected production, sale price and land utilization of some vegetable is as follows: Table 7: Expected Production and Land Utilization Land Production Production Vegetable Utilization Quantity (kg)/ Quantity (Acres) Acre (kg) 28,000 84,000 Cucumber 3 18,000 54,000 Capsicum 3 24,000 72,000 Tomatoes 3 Sale Price* Rs. / (kg ) 27 47 47 *The prices of vegetables depend on demand and supply and environment conditions.

Normally the off – season vegetables prices are higher than seasonal vegetables. 10 11.
