This guide provides a detailed overview of ridge gourd farming, including best practices for planting, managing, and harvesting this nutritious crop.

Ridge Gourd Crop at a Glance

Biological Name

The botanical name of ridge gourd is Luffa acutangula. It belongs to the Cucurbitaceae family, which includes other gourds and melons.

Cropping Season

Ridge gourd plant can be grown throughout the year, but the optimal seasons are during the summer and monsoon periods. The primary growing seasons are from March to June and from July to October.

Crop Type

Turai plant is an annual vine crop that produces elongated, ridged fruits. It is widely cultivated for its tender fruits used as vegetables.

Production and Consumption

Ridge gourd is cultivated extensively in states like Andhra Pradesh, Maharashtra, Karnataka, and Tamil Nadu. The fruits are consumed locally and are also transported to other regions. They are valued for their low-calorie content and high nutritional value, particularly their vitamin C and dietary fiber.

Export

India exports ridge gourd to countries with significant Indian populations, such as the United States, Canada, and the United Kingdom.

Required Climatic Conditions

Warm and humid climates are ideal for its growth and development. The optimum temperature range is 25-30°C, while temperatures between 32-40°C are highly favorable for excellent vegetative growth and fruiting.

Soil Requirement

Ridge gourd prefers well-drained, fertile soils rich in organic matter. Sandy loam and loamy soils with a pH range of 6.0 to 7.5 are ideal. The soil should be prepared to ensure good drainage to prevent waterlogging, which can harm the plants.

Land Preparation

Prepare the land by ploughing once or twice, depending on the soil type. Mix 3 tons of Farm Yard Manure (FYM) and 3 Liter of composting bacteria in the field, allowing it to decompose in open air for 10 days. Spread this mixture evenly over the soil and use a rotavator to achieve a fine tilth throughout the field. Prepare raised beds, 150 – 180 cm wide bed preparation, by using a tractor.

Sowing

Seed Rate

The recommended seed rate for ridge gourd is 500-800 gm per acre. Seeds should be sown directly in the field after proper land preparation.

Variety

Choosing the right variety is crucial for maximizing yield. Popular varieties include:

• Pusa Nasdar
• CO-1
• Syngenta Chikna
• HyVeg Raja
• Gentex Prince
• Shine Luca
• Grow Delight Aviraj
• Green Gold
• Rudraksh Dhruv
• East West Palee
• Arka Sumeet

Seed Treatment

For effective seed treatment, use Thiamethoxam 30% FS at 10 ml / kg seed to protect against sucking pests. Combine with Carbendazim 50% WP at 3 gm / kg seed to prevent fungal diseases. This dual treatment ensures healthier germination and robust plant growth. 

Spacing

Maintain a spacing of 5 to 6 feet  between rows and 2 feet between plants within a row. This spacing ensures adequate air circulation and sunlight penetration, which are essential for healthy plant growth.

Nutrient Management

Fertilization

Balanced fertilization is essential for the optimal growth of ridge gourd:

• The total N:P:K requirement is 80:80:100 kg per acre.
• Basal Dose: During the final land preparation, apply 50% of the nitrogen and the entire phosphorus and potassium as the basal dose.
• Top Dressing: Apply 25% of the nitrogen at 30 days after sowing and the remaining 25% at 50 days after sowing.

Irrigation Management

Ridge gourd requires consistent moisture for optimal growth. Key irrigation practices include:

• Frequency: Irrigate immediately after sowing and then regularly at intervals of 2-5 days, depending on soil moisture levels and weather conditions.
• Methods: Drip irrigation is recommended for efficient water use and to reduce the risk of diseases.

Intercultural Operations

Weeding

Regular weeding is necessary to keep the field free of competing weeds. Perform two to three hoeing sessions during the early growth stages to control weeds.

Training and Pruning

Train the vines to climb on trellises or supports to improve air circulation and sunlight exposure. Prune excess lateral shoots to promote the growth of the main vine and increase fruit production.

Crop Protection

Crop protection includes pest and disease management. Below are the pests and diseases that affect bitter gourd crops.

Pest Management

Common pests affecting bitter gourd include leaf miner, fruit flies, white fly, thrips, aphids, and red pumpkin beetles. Integrated Pest Management (IPM) strategies should be employed:

Leaf miner

Leaf miners are larvae that feed on the mesophyll tissue within leaves, creating irregular mines that may become necrotic. They can also tunnel into stems, hindering plant development, and sometimes attack the fruit as well.

Organic Control: Spray Azadirachtin or Neem oil @ 2 ml per lit water

Chemical Control: Spray Abamectin 1.9% EC – 0.5 ml OR Thiamethoxam 25% WG – 0.5 gm OR Cartap Hydrochloride 50% SP –  1.5 gm per liter water.

Sucking Pest – Thrips, Aphid, Whitefly 

In Ridge gourd crops, sucking pests like thrips, aphids, and whiteflies suck the leaf sap, weakening the plants and leading to stunted growth and reduced yields.

Mechanical Control: Install Yellow and Blue sticky traps @ 10 per acre

Organic Control: Spray Azadirachtin or Neem oil @ 2 ml per lit water

Chemical Control: Spray Acetamiprid 20% SP – 0.5 gm OR Thiamethoxam 25% WG – 0.5 gm OR Dimethoate 30% EC 2 ml OR Imidacloprid 17.8% SL – 0.5 ml per liter 

Fruit Fly

Fruit flies feed on the internal tissues of fruits, causing premature fruit dropping, rotting, and yellowing.

Mechanical Control: Install 4-5 fruit fly traps per acre in the field.

Chemical Control: Spray Bayer Fenos Quick (Flubendiamide 90 + Deltamethrin 60 SC) 0.5 ml OR Ampligo (Chlorantraniliprole + Lambda cyhalothrin) per liter water.

Pumpkin Beetles

Pumpkin beetles damage the roots by feeding on them, while their grubs consume the leaves.

Chemical Control: Spray Acephate 75% SP – 2 gm OR Super D – 2 ml per liter water.

Nematode 

Symptoms include premature leaf fall, wilting and decline in growth and fruit production. Roots of infected plants show typical galls/knots. 

Organic Control: Drench Paecilomyces Lilacinus @ 2 liters per acre.

Chemical Control: Drench Bayer Velum Prime – 300 ml per acre.
