Area, Production and Productivity
Ridge Gourd is cultivated in approximately 24,800 Acres in India. And the average yield is 39t/acre. Total production is approximately 3,16,925 Tons.
Climate and Seasons
Ridge gourd can be cultivated during summer and rainy seasons but not during winter in areas, where the temperature goes below 25°C, since it requires a temperature of 25 to 35°C, for germination of seeds.
It grows well in loamy soil or loose soil. Proper drainage is required.

The field is to be ploughed three times before sowing. Field Yard manure to be applied to the fields @ 125 Kg and Neem Cake @ 250 Kg per acre along with Azospirillum 5 Kg and 6.5 Kg of Pseudomonas after 2nd ploughing. It is desirable if the pH value of the soil is at 6.5 to 7. Good drainage for water is required.
Propagation of the plant is through seeds.
Sowing, Nursery and Transplanting
About 12 kg seed per Acre is required for ridge gourd cultivation.
The seeds of ridge gourd are very hard and having a very smooth surface and may take more time to germinate. In order to enable for earlier germination of seeds, they are to be first roughed lightly with rolling over a sand paper and soaked in luke warm water over night. Before sowing, the seeds are to be treated with Trichoderma viride @ 4 gm per kg or Pseudomonas fluorescens @ 10 gms per kg of seeds.
The seeds can be directly sowed three numbers in a pit or can be grown initially in a polythene bag filled with same soil and transplanted at the pits after a healthy growth of the plant. Thinning to two plants after healthy growth of plants to be carried out.
The plants are sown at a spacing of 150 X 200 cm.
The seeds are sown following two methods. One is Bed type the other is Pits or furrows type. Generally the Bed type method, is followed for Trellis or raised type of growing and Pits type is followed for ground trailing method of growing. In ground trailing method, the fruits will have a flat side whereas in raised method the fruits will be round shape.
Rotation type of cropping can be followed.
Drip Irrigation system is best suited for Ridge gourd growing. In this the lateral pipes are laid at an interval of 1.5 Meters and the drippers spaced @ 60cm in between with a water capacity of 3.5 Litres per hour.
N-P-K at the rate of 60-85-75 kg per acre before sowing and N @ 50 kg per acre after 30 days. Spray Ethrel @ 2.5 ml per 10 litres of water after 15 days of sowing and once in a week after that. This will help increase in yield.
Removal of weeds and earthing up of soil to the plants to be carried out before application of fertilisers. Application of Fluchloralin @ 2.5 kg per acre or Bensulide @ 15 Kg per acre to the filed 15 days before sowing helps control weeds.
Pests and Management
Fruit fly (Bacterocera cucurbitae)
Lays eggs on the flowers, fruits and eats the contents of the fruits when the eggs got hatched and become maggots. Causing rotting of the fruits.
To Control this, cover the fruits with polythene bag wrapped around. Remove the affected fruits by hand and destroy them by dipping in hot water with disinfectant solution. Do not throw the affected fruits on the earth. Using Light Trap with poison baits like hanging a coconut shell applied inside with Molasses or Gur paste with Furadan granules, will attract the flies and kill them.
Red Pumpkin Beetle (Aulacophora foveicollis)
Eats Leaves and as a result the leaves become curly, dry and fall down. Their Grubs inside the soil eat the stem and root portion, resulting in the plant dying.
To control this, granules of Furadon 3 G can be mixed with the soil at the base around the plant.
Aphids (Aphis gossypii)
Suck sap from the leaves. Leaves become curly and fall down. Aphids are also carrier of Mosaic virus.
To control this, spraying the plant with tobacco solution or Malathion(0.1%) can be carried out.
Root knot nematode (Meloidogyne incognita acrita)
Attacks roots of the plant by forming knots on the root portion resulting in damage of plants and productivity. Crop rotation, deep ploughing and exposure of the field to sun, applying insecticides before sowing can control this disease.
Diseases and Management
Yellow wine Mosaic Virus
Causes heavy damage to the crops due to curling and wilting of leaves, retarded growth, lower productivity. In order to reduce loss due to this, Seeds can be selected from disease free plants, virus resistant variety seeds also can be used. As a precaution, the seeds can be soaked in hot water having a temperature 55°C temperature.
Powdery Mildew (Sphaerotheca fuliginea)
Appearance of grey or white patches on the leaves and spreads rapidly throughout the plants having a powdery appearance of the plants, resulting in defoliation of the plant.
Spraying of Karathane (0.5%) or Carbendazim (0.1%) can control this disease.
Downy mildew (Pseudoperonospora cubensis)
This disease appears during rainy seasons with high humidity. The leaves get the appearance of as such they have been soaked in water at the bottom and angular portions. This will cause damage of entire plant quickly. Immediate removal of affected leaves and spraying of Dithane M-45 (0.2%) over the leaves and lower side can control this disease.

The harvest can be done by hand picking and sorting according to the weight and length of the fruits.
They can be marketed either through local markets or through marketing agents.
Post Harvest Technology
Ridge Gourd has to be used immediately after harvest. So the earlier the marketing, the better for the cultivator.
