2. DESCRIPTION OF TURMERIC
Turmeric is a herbaceous perennial plant that grows up to about three feet in height. It
has long, lance-shaped leaves with a distinct midrib and a vibrant green color. The plant's
rhizomes, which are the stems that grow underground, are brightly colored and range
from golden yellow to deep orange. These rhizomes are harvested, cleaned, and dried to
produce the turmeric powder that is commonly used.
Turmeric powder has a warm, earthy aroma and a slightly bitter and peppery taste that
adds depth and complexity to dishes. The powder is bright yellow in color, which makes it
a visually striking ingredient. It can stain surfaces and fabrics easily, so it's recommended
to handle it with care.
In addition to its culinary usage, turmeric has a rich cultural and medicinal history. It has
been used in traditional medicine for centuries for its potential healing properties and is
believed to have anti-inflammatory, antioxidant, and antimicrobial effects.
Overall, turmeric is not only a flavorful ingredient but also a fascinating plant that has
played a significant role in various cuisines and cultures.

Turmeric is primarily cultivated in tropical and subtropical regions because it requires a warm and humid climate with
temperatures between 68°F and 86°F (20°C and 30°C) to thrive. Here is a general overview of the cultivation process:

4. HOW TURMERIC IS CULTIVATED
1. Soil Preparation: Turmeric prefers well-drained, loamy soil with a pH between 5.5 and 7.5. The land is prepared by plowing
and harrowing to ensure a fine texture and to remove weeds and rocks.
2. Propagation: Turmeric is propagated through rhizomes, which are the underground stems. These rhizomes are obtained
from mature turmeric plants and are cut into small pieces, each containing at least one bud or "eye."
3. Planting: The rhizome pieces are planted at a depth of about 2 to 3 inches (5 to 7.5 cm) with the buds facing up. They are
spaced about 12 to 18 inches (30 to 45 cm) apart to allow room for growth.
4. Watering: Adequate irrigation is crucial to ensure optimal growth. Turmeric requires regular watering, especially during dry
periods, but excessive water should be avoided as it can cause rhizome rot.
5. Fertilization: Turmeric plants benefit from organic manures and compost. Nitrogen-rich fertilizers can be applied during the
initial stages of growth, but it's important to avoid excessive nitrogen as it can lead to excessive leaf growth instead of rhizome
development.
6. Weed Control: Regular weeding is essential to prevent competition for nutrients and maintain a weed-free environment
around the plants.
7. Harvesting: Depending on the variety, turmeric is typically ready for harvest after 7 to 10 months when the leaves start to
turn yellow and dry. The rhizomes are carefully dug out of the ground using spades or hand tools, ensuring that the plant is
not damaged.
8. Processing: After harvesting, the rhizomes are thoroughly washed, boiled, and dried in the sun or using commercial drying
methods. Once completely dry, they are ground into powder form.
It's worth noting that this is a general overview of turmeric cultivation, and specific practices may vary depending on the
region and farming methods. Farmers also need to be mindful of diseases, pests, and other environmental factors that can
affect turmeric yield.
