India is the world`s fifth largest producer of tomato accounting for 6.0% of world production. Tomato is the third most important vegetable of India by sharing 8.5% of total vegetable production. The total tomato production is 8.6 million tonnes and its productivity is 14.0 t/ha which is half of the world productivity. Orissa, Andhra Pradesh and Karnataka are the major tomato growing states. Tomato (Lycopersiconesculentum) is an important crop of solanaceous group with potato, brinjal and chilli.  Sikkim is gifted with suitable climates for round the year tomato cultivation. It is cultivated in the open field during rabi season and under protected condition during summer and rainy season.

NUTRITIVE VALUE                                                  

Although a ripe tomato contains as much as 93 to 94 percent water, it has a high nutritive value being a good source of vitamins and minerals. It is very appetizing and removes constipation and has a pleasing and refreshing taste. Nutritive value of tomato is given below (per 100 g of edible portion) which may vary with variety and climate.

The main purpose of protected cultivation is to create a favourable environment for the sustained yield as to realize its maximum potential even in adverse climatic conditions. The protected structures may be a high cost or low cost polyhouse, net house, tunnels etc. A partially ventilated low cost polyhouse with both polythene and agroshed net may be suitable for farmers.

The site for protected cultivation should be accessible, sunny, with no waterlogging. To minimize the diseases new area should be selected for cultivation. The soil should be well –drained, loamy with adequate organic matter (less than 2.0%). Crops are successfully grown in the moderately acidic soils (pH6.0-7.5). The pHcan be maintained by adding lime/dolomite @ 100g/m2


Tomato prefers moderate temperature and thrives well in the temperature range of 25-300C. The prevalence of low temperature and high humidity causes severe infestation of diseases.


Seeds are sown in raised beds under protected structures. Seeds can be sown about 25-25 days before planting. The average seed rate for tomato is 350-400g/ha. Seeds are sown with row spacing of 10 cm and seed spacing of 0.5 cm. densely populated seeds produce weak and lanky seedlings. The beds should be drenched with Trichoderma+Pseudomonas culture @ 2% to manage damping  off.


Indeterminate tomato varieties are suitable for cultivation under polyhouse. Avtar, Indam hybrid, All Rounder, ArkaMeghali, ArkaSurabhi, etc. are suitable varieties for tomato cultivation.


Tomato should be planted on the raised bed with the bed width of 1.5m. There should be a path of 0.6m between two beds. 20-25 day old seedlings should be planted at the distance of 1.0x0.8cm before planting the root of seedling should be dipped for 15 minutes inTrichoderma+Pseudomonas culture @ 10%. Planting should be preferably be done in small pits for better root development.


The nutrient requirement of tomato is moderately high (N100,P60, K80 kg/ha) and shows good response with the addition of nutrients. FYM should be applied @ 5.0kg/m2along with neem cake @200g/m2 . At the time of planting seedling should be treated with Azospirillum+PSB(20%) for 15 minutes. The addition of vermicompost @ 1kg/m2 further improves the production.


Tomato is a shallow rooted crop and roots are restricted within 15-20 cm of soil so light earthingup should be done after 30 days and 45 days of planting. Good quality water should be applied at 10 days interval. The plants should be provided with strong multiple stakes after one month of planting.



Late blight of tomato is the most devastating disease caused by a fungus Phytophthorainfestans. It infects and destroys the leaves, stems and fruits. Its infection is most rapid during conditions of high moisture and moderate temperatures (20-250 c).


1. Nursery soil treatment with Trichodermaculture @2%.

2. Soil drenching with Trichoderma culture@ 2% before planting.

3. Seedling treatment with Trichoderma culture@10% for15 minutes.


Early blight of tomato, caused by the fungus Alternariasolani, is a common foliar disease of tomato. This disease causes direct losses by the infection of fruits and indirect losses by reducing plant vigour. The disease can be managed by spray of Bordeaux mixture (1:1:100).

GREY MOULD (Botrytis)

Grey mould is a common and often serious fungal disease( Botrytiscinerea ) is an important disease of tomato and its infection occurs after flowering and fruit set. In case of severe infection flowers and pedicel starts dying and in later stage fruits also starts rotting. The infection starts from peduncle end and infected fruits are not suitable for consumption.


Application of Bordeaux mixture (1:1:100)after one month of planting.In case of severe infestation spray of kavach (clorothalonil) @ 1.5g/l minimizes the infestation.


Septoria leaf spot is caused by a fungus, Septorialycopersici. It is one of the most destructive diseases of tomato foliage and is particularly severe in areas where wet, humid weather persists for extended periods.This disease spreads upwards from oldest to youngest growth. If leaf lesions are numerous, the leaves turn slightly yellow, then brown, and then wither. Fruit infection is rare.


1. Remove diseased leaves. If caught early, the lower infected leaves can be removed and burned or destroyed.

2. Improve air circulation around the plants. If the plants can still be handled without breaking them, stake or cage the plants to raise them off the ground and promote faster drying of the foliage.

3. Mulch around the base of the plants

4. Do not use overhead watering.


The average yield of tomato under protected conditions may vary 6-8kg/m2 if proper care is taken .The average yield per plant may be 3-4kg/plant with the fruit number of 40-60 / plant and fruit weight of 80-90g.


The cultivation of tomato is highly profitable if fruits are harvested between June –October. They cost of cultivation may vary from Rs.20-25/m2 while the earning may be between Rs.100-130/m2. So the cost benefit ratio in tomato is generally as high as 1:4.
