Efficient Cultivation of Laal Saag (Red Amaranth)
Red Amaranth, commonly known as "Lal Saag" in local languages, is also referred to as Amaranthus. It is widely cultivated as a leafy vegetable. In India, it is grown extensively in various regions. Apart from India, its cultivation is widespread in South America, Southeast Asia, and West and East Africa. A warm and rainy season is suitable for its cultivation. Through this post, we will go through important information about the ideal time for growing Red Amaranth, its climate requirements, soil conditions, field preparation, irrigation management, weed control, and pest and disease management.
How to Cultivate Amaranth?
Optimal Time for Cultivation
- The best time for cultivating red amaranth is between summer and the monsoon season. This crop thrives in warm weather, so it is primarily planted between June and September. In some regions, it is also sown between February and March. While it can be grown during different seasons depending on the region, extreme cold and frost have adverse effects on its growth. In warm climates, the plants grow rapidly, and the leaves are ready for harvest within 25 to 30 days.
Suitable Climate
- Amaranth cultivation is suitable for both temperate and subtropical climates. It can also be grown in tropical climates. The ideal temperature for plant growth ranges from 18°C to 30°C. Choose a location where the plants receive adequate sunlight daily for optimal growth.
Suitable Soil
- Red amaranth can be grown in almost any type of soil, but loamy soil or well-drained light soil is considered best for high yields. The soil pH should range between 5.5 and 7.5. It can be grown in both alkaline and acidic soils, but the presence of organic matter in the soil is crucial for good yields. Good soil drainage is also important, as waterlogging can damage the plant roots.
Best Varieties
- For better yields, selecting high-quality varieties is essential. Some recommended varieties include Sarpan Seeds Rajgira Amaranthus Red, Iris Red Amaranthus C01, Sirukeerai, Pusa Chhoti Chaulai, Pusa Kirti, Pusa Kiran, Arka Suguna, and Arka Arunima.
Seed Quantity
- The quantity of seeds depends on the sowing methods. If you are directly sowing in the field, you'll need 800 grams to 1 kilogram of seeds per acre. However, if you are growing the plants in a nursery before transplanting them into the field, you'll need 200 grams of seeds per acre.
Field Preparation
- First, execute a deep plowing of the field using a soil-turning plow. Follow this with 2-3 lighter plowings. You can use a cultivator or harrow for the lighter plowings. For a good yield of amaranth, mix 8 to 10 tons of cow dung manure per acre into the field. Along with this, apply 35 kilograms of urea, 22 kilograms of DAP, and 14 kilograms of MOP per acre. After mixing the manure, irrigate the field. Three to four days after irrigation, when the surface of the land appears dry, perform another thorough plowing of the field. After plowing, use a rotavator to make the soil crumbly. Then level the field with a plank. This preparation will help prevent waterlogging during the rainy season.
Sowing Method
- Sow the seeds in rows. There should be a distance of 8-10 inches between rows and a distance of 4-6 inches between plants.
Irrigation Management
- If the soil has sufficient moisture at the time of transplanting, do not irrigate immediately after sowing. However, if you are sowing in dry soil, lightly irrigate immediately after sowing. This will help in seed germination. Irrigate the plants as needed. During the summer season, irrigate at intervals of 7-10 days. If it rains, irrigation is not required. Ensure that there is no waterlogging during irrigation, as it may cause root rot.
Weed Control
- Controlling weeds in this crop is very important. Weeds absorb essential nutrients, which hinders plant growth. In small areas, weeds can be removed manually through hand weeding and hoeing. This is an ancient and effective method, but it requires more labor and time. Before using chemical herbicides, always consult agricultural experts.
Disease and Pest Control
- The crop of amaranth is susceptible to various diseases and pests, including leaf spot disease, whitefly infestation, and root rot. To protect the crop from these diseases and pests, continuously monitor the field. As soon as any symptoms of diseases or pests appear, promptly use appropriate medications.
Harvest
- The first harvest can be done 30 days after sowing. The second harvest can be done 45 days after sowing, and the third harvest can be done 55 days after sowing. When the amaranth plants reach a height of 25-30 centimeters above the ground, harvest them. Take care during harvesting to avoid damaging the plant roots.
