Kholrabi farming in india

Kohlrabi, scientifically known as Brassica oleracea var. gongylodes, is a versatile and nutritious vegetable that is widely cultivated in India. With its unique taste and numerous health benefits, kohlrabi has gained popularity among farmers and consumers alike. In this article, we will explore the cultivation practices of kohlrabi in India, from selecting the right variety to harvesting and post-harvest management.

Introduction to Kohlrabi
Kohlrabi, also known as German turnip or knol-khol, is a member of the Brassica family and closely related to cabbage, broccoli, and cauliflower. It is a biennial vegetable crop that is primarily grown for its swollen stem, which is crisp and sweet, resembling a turnip. Kohlrabi is rich in essential nutrients such as vitamin C, potassium, and dietary fiber, making it a valuable addition to a healthy diet.

Selection of Varieties
When cultivating kohlrabi in India, it is essential to choose the right variety based on the agro-climatic conditions and market demand. Some popular varieties suitable for Indian conditions include Early White Vienna, Purple Vienna, and Superschmelz. These varieties exhibit good adaptability to different regions and offer high yield potential.

Soil and Climate Requirements
Kohlrabi thrives well in well-drained soils with a pH range of 6.0 to 7.5. It prefers fertile loamy soils enriched with organic matter. The crop requires a cool climate for optimal growth and development. A temperature range of 15 to 20 degrees Celsius is considered ideal for kohlrabi cultivation. Excessive heat can result in bolting and poor-quality produce.

Seed Sowing and Nursery Management
To ensure successful germination and healthy seedlings, it is recommended to raise kohlrabi plants in a nursery. Sow the seeds in raised beds or seed trays filled with a well-prepared seedling mix. Maintain adequate moisture and provide partial shade to protect the young seedlings from harsh sunlight. Transplant the seedlings when they reach the 4-6 leaf stage.

Transplanting and Field Preparation
Prepare the main field by plowing and harrowing to obtain a fine tilth. Kohlrabi plants should be transplanted at a spacing of 30 cm between rows and 20 cm between plants. Ensure proper water availability before transplanting to reduce transplant shock. Mulching the field with organic materials helps in conserving moisture and suppressing weed growth.

Irrigation and Water Management
Kohlrabi requires regular and uniform irrigation throughout its growth stages. Adequate moisture is crucial for bulb formation and preventing cracking. Avoid waterlogging, as it can lead to diseases and root rot. Drip irrigation or sprinkler irrigation systems are suitable for kohlrabi cultivation, ensuring efficient water distribution.

Nutrient Management
Appropriate nutrient management plays a vital role in obtaining high-quality kohlrabi produce. Conduct soil testing to determine the nutrient status and make necessary amendments. Apply well-decomposed farmyard manure or compost before field preparation. Supplement the crop with balanced doses of nitrogen, phosphorus, and potassium during different growth stages.

Pest and Disease Control
Kohlrabi is susceptible to various pests and diseases, including cabbage aphids, diamondback moth, flea beetles, and black rot. Implement integrated pest management strategies such as crop rotation, biological control, and judicious use of pesticides to minimize pest damage. Regular scouting and timely action can help prevent major losses.

Weed Management
Weed competition can significantly affect the growth and yield of kohlrabi. Employ cultural and mechanical methods like hand weeding, hoeing, and mulching to suppress weed growth. Apply pre-emergence herbicides carefully as per the recommended dosage and timings. Monitor the field regularly and take corrective measures to keep weeds under control.

Harvesting and Yield
Kohlrabi reaches maturity within 60 to 80 days after transplanting, depending on the variety. Harvest the bulbs when they attain a size of 6-8 cm in diameter. Use a sharp knife to cut the swollen stems just above ground level. Proper handling and grading of harvested kohlrabi ensure better market acceptance. The average yield of kohlrabi can range from 15 to 20 tons per hectare.

Post-Harvest Management
After harvest, it is crucial to handle kohlrabi carefully to maintain its quality and shelf life. Remove the leaves and roots from the bulbs and wash them thoroughly. Sort and grade the produce based on size and appearance. Pack the kohlrabi in suitable containers or crates to prevent damage during transportation. Proper storage conditions, with temperatures around 0 to 2 degrees Celsius and high humidity, help prolong the shelf life.

Market Potential and Benefits
Kohlrabi has gained popularity in the Indian market due to its unique flavor and nutritional benefits. The vegetable is used in various culinary preparations, including salads, stir-fries, soups, and pickles. Its high fiber content aids digestion, while the presence of antioxidants promotes overall health. With the increasing demand for healthy and organic food, kohlrabi cultivation presents promising market potential for farmers.
