Advantages of growing turmeric in a polyhouse:
Growing turmeric in a polyhouse has several advantages, including:
- Controlled environment: In a polyhouse, the environment can be controlled, including temperature, humidity, light intensity, and irrigation. This ensures that the crop is protected from extreme weather conditions, pests, and diseases, which can result in better yield and quality.
- Extended growing season: Turmeric requires a warm and humid climate to grow well. A polyhouse can extend the growing season beyond the traditional season, which is limited by weather conditions. This allows for multiple harvests in a year, increasing the yield and profitability.
- Improved yield and quality: The controlled environment of a polyhouse can help improve the product and quality of turmeric by providing optimal growing conditions. It can also protect the crop from pests and diseases, reducing the need for pesticides and other chemicals.
- Water conservation: In a polyhouse, water can be conserved through drip irrigation, ensuring that the plants receive the required water without wastage. This is especially important in areas where water is scarce.
- Higher profitability: Growing turmeric in a polyhouse can result in higher profitability due to better yield and quality, extended growing seasons, and reduced input costs. It can also help farmers overcome market fluctuations and increase their income by selling the crop at a premium price.
Overall, growing turmeric in a polyhouse can provide a more sustainable and profitable option for farmers while also ensuring better quality and yield of the crop.
Design and construction of a polyhouse for turmeric cultivation:
Designing and constructing a polyhouse for turmeric cultivation requires careful planning and consideration of several factors. Here are the steps involved:
- Site selection: The site for the polyhouse should be flat, well-drain, and away from sources of pollution. It should also receive adequate sunlight and have access to water and electricity.
- Size and shape: The size and shape of the polyhouse will depend on the number of turmeric plants to be grown and the available space. A rectangular shape is familiar for polyhouses, as it maximizes the use of space and allows for the efficient use of materials.
- Frame construction: The frame of the polyhouse can be made of wood, bamboo, or metal. The structure should be sturdy enough to withstand wind and rain and tall enough to allow for proper air circulation and ventilation.
- Covering material: The covering material for the polyhouse can be made of polyethylene, polycarbonate, or fiberglass. Polyethylene is the most commonly used material, which is affordable and easy to install.
Ventilation: Proper ventilation is essential for the health of the turmeric plants. The polyhouse should have vents or windows that can be opened and closed to regulate temperature and humidity.
- Irrigation: Drip irrigation is the most efficient method of watering turmeric plants in a polyhouse. The irrigation system should be designed to provide water directly to the roots of the plants while minimizing water waste.
- Lighting: Turmeric plants require adequate sunlight for optimal growth. If natural light is insufficient, artificial lighting can supplement the light requirements.
- Flooring: The flooring of the polyhouse can be made of gravel or concrete to prevent waterlogging and provide a stable surface for the plants.
Overall, designing and constructing a polyhouse for turmeric cultivation requires careful planning and consideration of several factors. Ensuring that the polyhouse provides the optimal growing environment for turmeric plants and can withstand weather conditions and other environmental factors is essential.

When selecting turmeric varieties for polyhouse cultivation, it is important to consider the specific growing conditions in the polyhouse, such as temperature, humidity, and light intensity. It is also important to assess market demand and the intended use of turmeric, such as for medicinal or culinary purposes. The selected variety should be disease-resistant, have a high yield, and meet market demand.
Seed selection and preparation for turmeric cultivation in a polyhouse:
Seed selection and preparation are critical in turmeric cultivation, even in a polyhouse. Here are the steps involve:
- Seed selection: Select high-quality turmeric seeds that are disease-free and uniform in size. Purchasing seeds from a reputable supplier or using seeds saved from a previous crop is a recommendation.
- Seed treatment: To prevent seed-borne diseases, the seeds to be treat with a fungicide or a biocontrol agent. Soak the seeds in a 1% Bordeaux mixture solution or a biocontrol agent for 30 minutes before planting.
- Bed preparation: Prepare the beds with well-drain soil that is rich in organic matter. The beds should rise to prevent waterlogging and drip irrigation should be install to provide water directly to the roots of the plants.
- Seed planting: The seeds must plant at a depth of 5-7 cm and space 20-25 cm apart. Cover the beds with a thin layer of soil or mulch to maintain moisture and prevent weed growth.
Germination and growth: The seeds will germinate within 2-3 weeks, and the plants will start to grow. The polyhouse environment should be maintained at a temperature of 25-30°C and relative humidity of 60-70% for optimal growth. Adequate ventilation and lighting should also be provided.
- Thinning and weeding: Once the plants have grown to a height of 15-20 cm, they should be thin to ensure proper spacing between the plants. Weeding should also be done regularly to prevent competition for nutrients and water.
- Fertilization: The plants should be fertilized with a balanced fertilizer that contains nitrogen, phosphorus, and potassium. The fertilizer should be apply at regular intervals to ensure optimal growth.
Overall, seed selection and preparation are critical steps in turmeric cultivation, even in a polyhouse. The plants can grow healthy and yield a high-quality crop by following these steps.
