Introduction to turmeric farming in polyhouse

Turmeric is a popular spice in Indian households; it’s a yellow color spice with multi-benefits. Turmeric, also called Haldi, boosts immunity in the body, helps to heal wounds, brings a natural glow to your face, and is used in Indian curry recipes.

Haldi is a flavoring and coloring agent loaded with antibiotics and nutrients. Curcumin is the plant pigment that provides turmeric with its vibrant color.

Does the vibrant color of Haldi energize you and trigger you to know more about its farming process. We will highlight the critical steps in organic turmeric farming in Polyhouse.

Let’s get into the article.

Soil and climate requirements for turmeric farming in Polyhouse

Black loam soil, rich loamy soil, and clayey soil or red soil are ideal soil drained properly for turmeric farming. Alkalinity or logging water destroys turmeric production in the polyhouse setup.

Turmeric requires warm plus humid weather and a temperature range of 20-30 degree celsius with 1500 mm or more rainfall. The early-planted turmeric with proper irrigation produces a high yield in polyhouse.

Methods of Turmeric farming in polyhouse

There are two specific methods of Turmeric farming in the polyhouse such as:

• Furrows and Ridges

The furrow method in polyhouse is used in heavy soil on leveled land under irrigation conditions. The field will be partitioned into furrows and ridges at a distance of 75 cm each with a length of around 35 meters.

• Flatbeds

Flatbeds are prepared 1 m in width and length depending on the slopes designed in the polyhouse. The beds are made under the condition of light soil.

In polyhouse organic turmeric can be sown in pots and containers. They are cheerful and also encourage other crop growth like onion and ginger.

Planting process of turmeric

While planting in a polyhouse, prepare the spacing of 20-25 cm between plants and prepare a mixture of soil and 25g powdered neem cake; mix it well in each row. Pick healthy rhizomes seeds, put them in low pits, and wrap them with properly mixed compost.

Incorporate 10g compost and Trichoderma, which acts as a biofertilizer and protects the growth of the crop throughout from pests and disease.

Irrigation requirement in Turmeric crops

Irrigation before and after sowing is essential for developing Rhizomes and overall crop growth. The turmeric crop period is 7-9 months which varies in different varieties. 

Turmeric requires a weekly irrigation means at an interval of around 7-10 days. Over irrigation in turmeric plantation affects the quality of the rhizome and chances of getting fungal diseases will increase. Overall, 20-25 days of irrigation is prescribed for one crop session.

Harvesting of Turmeric Rhizomes

In about 7-9 months after plantation, rhizomes are ready for harvest and easily handpicked in the polyhouse. The fingers are separated from mother rhizomes and can be used in the next session of turmeric farming.

The turmeric yield per acre is around 8-10 tonnes, and it also fluctuates sometimes.

FAQs

Q2. What is the seed rate of turmeric cultivation in a polyhouse?

Ans. The seed rate of turmeric depends on the quality, color, planting material, and spacing. For example, Rhizomes, mother rhizomes cost 2000-2500 kg/ha, Finger rhizomes cost 1500-2000 kg/ha, and intercrop costs 400-500 kg/ha.

Q3. What are the essentials while preparing a polyhouse for turmeric farming?

Ans. There are five factors to be considered in site selection for the construction of polyhouse, accessibility to polyhouse, pollution, water logging, and facility of the semi-automated greenhouse.
