Cereals are any grass grown for the edible components of its grain (botanically, a sort of fruit known as a caryopsis), which consists of the endosperm, germ, and bran. India is the world's second-largest producer of rice, wheat, and other cereals. The global demand for cereals is creating an ideal environment for Indian cereal exports. Wheat, paddy, sorghum, millet (Bajra), barley, and maize are among the most important cereals. In this article, we will discuss Cereals which will be helpful for UPSC exam preparation.

Cereal Examples

• Wheat
• Maize
• Rice
• Barley
• Oats
• Rye
• Sorghum

Cultivation of Cereals

Planting

• Warm-season cereals are grown in tropical lowlands all year and in temperate climates during the frost-free season.
• Rice is typically grown in flooded fields, though some strains are grown on dry land. Other warm-climate cereals, such as sorghum, are adapted to arid conditions.
• Cool-season cereals thrive in temperate climates. The majority of a species' varieties are either winter or spring varieties.
• Winter varieties are sown in the autumn, germinate and grow vegetatively, and then go dormant during the winter.
• They begin to grow again in the spring and reach maturity in the late spring or early summer.
• This cultivation system conserves water and frees up land for another crop early in the growing season.
• Winter varieties do not flower until the spring because they require vernalization, or exposure to low temperatures for a genetically determined period of time.
• Farmers grow spring varieties where winters are too warm for vernalization or where the crop's hardiness (which varies by species and variety) is exceeded.
• Spring cereals are planted in early spring and mature later that summer, without vernalization. Spring cereals typically require more irrigation and yield less than winter cereals.

Harvesting

• The cereal plants' life cycle is complete once they have produced seeds.
• Plants die, turning brown and dry. Harvesting can begin as soon as the parent plants and seed kernels are reasonably dry.
• Cereal crops are universally machine-harvested in developed countries, typically using a combine harvester, which cuts, threshes, and winds the grain in a single pass across the field.
• Harvesting methods in developing countries range from combines to hand tools like the scythe or grain cradle, depending on labour costs.
• If a crop is harvested in humid conditions, the grain may not dry sufficiently in the field to prevent spoilage during storage.
• In this case, the grain is transported to a dehydrating facility where it is dried using artificial heat.
• Farmers in North America commonly deliver newly harvested grain to a grain elevator, which is a large storage facility that consolidates the crops of many farmers.
• The farmer has the option of selling the grain at the time of delivery or keeping ownership of a share of the grain in the pool for future sale.
• Small grain pests, rodents, and birds should be kept out of storage areas.

Difference between Cereals and Pulses

Cereals Production in India

• Cereals account for approximately 54% of total production in India.
• In terms of cereal production, India ranks third in the world, accounting for approximately 11% of total global production. In India, cereals are divided into coarse grains and fine grains.

Rice

• Rice is grown in areas with high humidity.
• It is best suited to deep clayey and loamy soil. This crop requires 150-300 cm of rain per year.
• West Bengal, Punjab, Uttar Pradesh, Andhra Pradesh, and Bihar are the top rice-producing states.
• Rice is the most common food consumed by the majority of Indians. India is the world's second-largest producer.

Wheat

• It is sown in temperatures ranging from 10 to 26 degrees Celsius. This crop requires 75-100 cm of rainfall.
• Wheat production thrives in fertile loamy and clayey soil with high fertility.
• The top wheat-producing states are Uttar Pradesh, Punjab, Madhya Pradesh, Rajasthan, and Haryana.

Maize

• This crop requires old alluvial soils from Karnataka, Maharashtra, Tamil Nadu, Telangana, and Madhya Pradesh.
• Maize thrives in temperatures ranging from 21 to 27 degrees. In terms of maize production, India ranks seventh worldwide.

Pulses

• Pulses are grown in sand and loamy soil with 25-60 cm of rainfall. India is the world's largest pulse producer.
• It is the primary protein source for Indian consumers.
• This crop yields a high-quality product, and India is a leading producer of it.
• Madhya Pradesh, Maharashtra, Uttar Pradesh, Rajasthan, and Andhra Pradesh were the largest contributors to this production.

Benefits of Cereals

• Greater flexibility and colonization success in all habitats.
• The ease with which it can be grown.
• Tillering produces more branches, resulting in a better yield per unit area.
• Because grains are compact and dry, they may be readily handled, transported, and stored without spoiling.
• Energy-giving food with high caloric content.
• Cereals include carbs, proteins, fiber, as well as a variety of vitamins and minerals.

Cereal Exports of India

• India is the world's largest producer and exporter of cereal products.
• Wheat, paddy, sorghum, millet (Bajra), barley, and maize are the major cereals.
• Previously, in 2008, India prohibited the export of rice, wheat, and other grains to meet domestic demand.
• Due to high demand in the global market and the country's surplus production, India permitted only limited amounts of the commodity to be exported.
• Rice (including Basmati and Non Basmati) accounts for 95.7% of India's total cereals exports in 2019-20. Other cereals, including wheat, account for only 4.3% of total cereal exports from India in 2019-20.
• Wheat's top export destinations for 2019-20 are Nepal, Bangladesh, the United Arab Emirates, and Somalia.
• Nepal, Benin, the United Arab Emirates, and Somalia are the top non-Basmati rice export destinations for 2019-20.
• Iran, Saudi Arabia, Iraq, and the United Arab Emirates are the top Basmati rice export destinations for 2019-20.

Conclusion

Cereals are the Gramineae grass family's edible seeds or grains. Rye, oats, barley, maize, triticale, millet, and sorghum are among the cereals farmed in many nations. Cereals are often regarded as nutritious staple foods in both industrialized and developing countries. Grains, often known as cereals, are the world's most essential staple food. It is believed to give 48% of human calories, or dietary energy. Grains are also used to feed cattle and to manufacture some cooking oils, fuels, cosmetics, and alcoholic beverages.
