Tobacco Soil And Climate Requirements

- Tobacco is harvested 90-120 days after transplanting, depending on variety and purpose. - Types of Harvesting: - Priming: Harvesting mature leaves from the bottom upward at intervals of 7-10 days.
- Stalk-cutting: Entire plant is cut at the base when all leaves are mature.
- Proper curing methods like air-curing, flue-curing, or sun-curing are used to improve tobacco quality.

- Flue-cured varieties:
- Kanchan, Jayasri, Anand-119
- Air-cured varieties:
- Abirami, Swarna, Bhavya - Chewing tobacco varieties:
- Dharani, Lal Ganga, Manasi

- Tobacco seeds are tiny and are initially grown in nurseries before transplanting.
- Seed Rate: 500-600 g/ha.
- Nursery Bed Preparation:
- Beds are made in well-drained soil and sterilized with formalin or through solarization to prevent fungal infections.
- Seeds are mixed with fine sand and spread evenly across the beds.
- Light and consistent watering is done to maintain moisture levels.
- Seedlings, 45-50 days old and 10-15 cm tall, are ready for transplanting.

- Tobacco thrives in light, well-drained loamy or sandy loam soils with a pH range of 5.5 to 7.5.
- The crop requires a warm and humid climate, with temperatures ranging between 20-30°C.
- It needs 500-1000 mm of evenly distributed rainfall throughout the growing season.
- Bright sunny days and dry weather during maturity enhance the quality of the leaves.

- Transplanting is carried out in well-prepared fields once the seedlings reach a height of 10-15 cm.
- Spacing of 75 cm between rows and 50 cm between plants is ideal for proper aeration and growth.
- Transplanting should be done in moist soil, preferably after light irrigation or rainfall.
- For the initial few days, shading is provided to minimize transplant shock.
