Tobacco

Eastern India, particularly parts of Bihar, cultivates tobacco, used to manufacture cigarettes and chewing products.

Tobacco

Nutrients

Tobacco 1

Tobacco plants require nitrogen, phosphorus, potassium, calcium and magnesium to grow.

Nitrogenous fertilisers like urea or ammonium nitrate are commonly used to supplement nitrogen levels in the soil.

Phosphatic fertilisers such as single superphosphate or diammonium phosphate are commonly used to supply phosphorus to the soil.

Potassium-based fertilisers like potassium chloride or potassium sulfate are applied to meet the potassium requirements of tobacco plants.

Lime or calcium-containing fertilisers like calcium nitrate can be used to address calcium deficiencies in the soil.

Magnesium sulfate or dolomite lime can be used to supplement magnesium levels in the soil.

Micronutrient-rich fertilisers or foliar sprays are utilized to address micronutrient deficiencies.

Irrigation requirements

Germination and seedling stage

During the initial stage of tobacco cultivation, sufficient moisture is crucial for seed germination and early seedling development. Adequate soil moisture should be maintained to ensure the successful germination and establishment of the crop.

Vegetative growth stage

As tobacco plants enter the vegetative growth stage, they require regular water supply to support leaf development and overall plant growth. Maintaining optimal soil moisture levels during this stage is important for the formation of healthy and vigorous leaves.

Flowering and maturation stage

As tobacco plants reach the flowering and maturation stage, their water requirement generally decreases. However, an optimum level of soil moisture should still be maintained to prevent excessive stress on plants and ensure the development of high-quality tobacco leaves.

In areas with inadequate rainfall or during dry periods, supplementary irrigation is necessary to meet the water demands of tobacco plants. Efficient irrigation methods, such as drip irrigation or furrow irrigation, can help optimise water usage and reduce water wastage.

It is important to note that excessive or insufficient water supply can affect the quality and yield of tobacco. Overwatering can lead to waterlogged conditions, which can promote disease development and reduce root health. On the other hand, water stress can negatively impact leaf development and result in lower-quality tobacco.

Local conditions and specific tobacco varieties may influence the precise water requirements for tobacco cultivation in a particular region. Consulting with local agricultural experts, extension services or experienced tobacco growers can provide valuable insights into appropriate irrigation practices for tobacco in a specific area.
