Capsicum, commonly known as bell pepper or sweet pepper, is a popular vegetable crop in India. Known for its vibrant colors and rich nutritional value, capsicum is cultivated extensively across the country. This guide provides a detailed overview of capsicum cultivation, from sowing to harvesting, to help farmers achieve high yields and superior-quality produce.
Capsicum Crop at a Glance
Biological Name
The biological name of capsicum is Capsicum Annuum. It belongs to the Solanaceae family, including tomatoes, potatoes, and eggplants.
Cropping Season
Capsicum can be grown throughout the year under protected cultivation, but the main seasons are the summer (March to June) and the winter (October to February).
Crop Type
Capsicum is an annual crop that produces bell-shaped fruits. It is grown for its edible fruits, which come in various colors such as green, red, yellow, and orange.
Production and Consumption
Capsicum is widely cultivated in India, with major production in states like Karnataka, Andhra Pradesh, Maharashtra, and Himachal Pradesh. It is consumed both fresh and cooked in various dishes, salads, and processed products.
Export
India exports capsicum to several countries, including the United States, the United Kingdom, and the Middle East, where it is highly valued for its taste and nutritional benefits.
Types of Capsicum in India
Several varieties of capsicum are cultivated in India, each with unique characteristics:
Green Capsicum (Shimla Mirch): Green capsicum is the most commonly grown variety in India. It is harvested before it ripens fully, which is why it retains its green color. It has a slightly bitter taste and is often used in salads, stir-fries, and curries.
Red Capsicum: This variety is harvested when fully ripe, giving it a vibrant red color. It is sweeter compared to green capsicum. Red capsicum has a sweet and slightly fruity taste, making it popular in salads, salsas, and roasted dishes.
Yellow Capsicum: Yellow capsicum is another fully ripened variety. It is harvested at the same stage as red capsicum but from a different cultivar. It offers a sweet and mild flavor, often used to add color and taste to various dishes like salads, pizzas, and pasta.
Orange Capsicum: Less common than the other varieties, orange capsicum is another fully ripened type with a distinct color. It has a sweet, tangy flavor and is used in gourmet dishes, salads, and stir-fries for its unique taste and color.
Purple Capsicum: This exotic variety is less commonly found and cultivated in India. It is known for its striking purple color. It has a slightly sweet taste and is used in specialty dishes and salads.
Miniature Capsicum: These are smaller versions of the standard capsicum, available in various colors like red, yellow, and orange. They offer a sweet taste and are often used as garnish, in gourmet dishes, and for snacking.
Required Climatic Conditions
Capsicum thrives in mild climates with temperatures ranging from 18°C to 30°C. It is sensitive to frost and extreme heat, making it suitable for Bell pepper cultivation in regions with moderate temperatures.
Soil Requirement
Capsicum prefers well-drained, fertile soils rich in organic matter. Sandy loam and loamy soils with a pH range of 6.0 to 6.8 are ideal. Good soil aeration is crucial for the healthy growth of capsicum plants.
Growing Season
In India, the capsicum growing season in India spans multiple periods: the wet season from May to August, the spring/winter season from October to December, and the summer season from February to March.
Land Preparation
Prepare the land by ploughing once or twice, depending on the soil type. Mix 5 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, 140 cm wide bed preparation, by using a tractor.
Sowing
Seed Rate
The recommended seed rate for capsicum is 200-250 grams per hectare. Capsicum Seeds should be sown in well-prepared nursery beds or trays.
Variety
Choosing the right variety is crucial for maximizing yield. Popular varieties include Syngenta Indra, Sarpan Tambi, Kedar and Krishna.
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.
Nursery
- Fill the trays with cocopeat at a rate of 1.2 kg per tray.
- Sow the treated seeds in the trays, using one seed per cell.
- Cover the seeds with cocopeat, stack the trays, and cover them with a polythene sheet for about 5 days until germination begins.
- After 6 days, place the trays with germinated seeds on raised beds inside a shade net.
- Spray M-45 or Carbendazim + Mancozeb at 2 grams per liter of water at 7, 15, and 25 days after placing on the raised beds.
- Drench with a solution of 19:19:19 fertilizer at 2 grams per liter + Carbendazim 50 WP (Bavistin) at 2 grams per liter of water at 10 and 20 days after placing on the raised beds.
Root Dip Treatment
Fill a flat container with 20 liters of water. Add 40 gm of Carbendazim 50 WP and 20 ml of Imidacloprid 17.8 SL to the water. Submerge the plant roots in this solution for 5 minutes before transplanting. For plants in pro trays, immerse the entire tray in the solution for 5 minutes.
Spacing
Maintain a spacing of 60-75 cm between rows and 45-60 cm 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 capsicum:
For optimal crop growth, a total N:P:K requirement of 80:100:120 kg per acre is recommended. During the final land preparation, apply 50% of the nitrogen and all the phosphorus and potassium as a basal dose. For top dressing, apply 25% of the nitrogen 30 days after sowing and the remaining 25% of the nitrogen 50 days after sowing. This balanced nutrient management ensures proper growth and maximizes yield potential.
Irrigation Management
Drip irrigation should be applied every other day, ensuring to check soil moisture first. Flood irrigation is recommended once a week, adjusted according to rainfall. During the summer season, irrigate at intervals of 5-6 days. After each Capsicum harvest, provide one irrigation session to support plant recovery. Regular monitoring and adjusting irrigation based on soil and weather conditions are essential for optimal Capsicum crop health.
Intercultural Operations
Weeding
Regular weeding is necessary to keep the field free of competing weeds. Manual weeding or the use of herbicides can be employed. Spray Bayer Sencor herbicide at a rate of 300 grams per acre, targeting only the inter-row weeds.
Training and Pruning
Train the plants to grow upright by providing support with stakes or trellises. Prune excess lateral shoots to promote the growth of the main stem and increase fruit production.
