Paddy Crop in India — Kharif Season, States & Facts

Crop type: Kharif (sown at the beginning of the monsoon season — June/July; harvested in October/November). Scientific name: Oryza sativa. Family: Poaceae (grass family).

Climatic requirements: • Temperature: 20°C to 35°C (warm and humid conditions). • Rainfall: More than 100 cm of rainfall per year; or adequate irrigation. • Soil: Clayey or loamy soil that retains water well; paddy fields are typically flooded (waterlogged conditions).

Growth stages:

1. Seedling stage: Seeds germinated in nurseries, then transplanted.
2. Vegetative stage: Plant grows in flooded fields.
3. Reproductive stage: Flowering and grain filling.
4. Maturity: Grains harden; field is drained before harvest.

Harvesting: October–November for the main Kharif crop. In some areas (southern states), two or three crops of rice are grown per year using irrigation.

India's major paddy-producing states:

1. West Bengal:

   • Consistently the largest rice-producing state in India.
   • The Ganga delta (Sundarban region) has ideal conditions for rice cultivation.
   • Multiple rice crops per year due to irrigation.

2. Uttar Pradesh:

   • Second largest rice producer; vast irrigated plains.
   • Basmati rice is grown in western UP (Tarai region).

3. Punjab:

   • Major Green Revolution state; high per-hectare yield.
   • Heavy groundwater use for rice irrigation — causing concern over groundwater depletion.
   • Basmati rice of Punjab is exported globally.

4. Andhra Pradesh and Telangana:

   • Krishna and Godavari river delta regions are major rice bowls.
   • Andhra Pradesh is sometimes called the 'Rice Bowl of India' due to its high productivity.

5. Tamil Nadu:

   • Cauvery River delta is key rice-growing area.
   • Known for varieties like Ponni and Samba.

6. Odisha:

   • Significant rice production; traditional rice varieties.

7. Bihar and Assam:

   • Eastern states with substantial paddy cultivation along river valleys.

Other producers: Chhattisgarh (sometimes called 'Rice Bowl of Central India'), Jharkhand, Madhya Pradesh.

India's rank: 2nd largest producer of rice in the world (after China). Also 2nd largest exporter.

Rice is the staple food for more than half of India's population, particularly in eastern, southern, and northeastern India.

Economic importance: • Rice is one of India's most important food crops and a major item of the Public Distribution System (PDS). • India is the world's leading exporter of non-basmati rice and a major exporter of basmati rice. • Paddy cultivation supports livelihoods of millions of farmers, particularly in states like West Bengal, Andhra Pradesh, and Tamil Nadu.

Nutritional value: • Rice is a carbohydrate-rich staple. • Brown rice (unmilled) retains more fibre and nutrients than white (polished) rice.

Green Revolution and paddy: • The Green Revolution of the 1960s–70s introduced High-Yielding Varieties (HYVs) of paddy (IR-8 variety). • Dramatically increased rice production in Punjab, Haryana, and UP. • However, it also led to heavy water usage and soil issues in the long term.

Environmental concern: • Paddy fields are a significant source of methane — a greenhouse gas contributing to climate change. • Waterlogged rice paddies produce methane through the activity of anaerobic microorganisms.

Students often confuse paddy and rice: • Paddy = rice plant with husk/hull still attached (the raw grain harvested from the field). • Rice = paddy after the husk has been removed by milling.

So: paddy (harvested from field) → milling → rice (edible grain).

Types of rice cultivation in India:

1. Ahu (Autumn rice): Sown in March–April, harvested in September–October — common in Assam.
2. Sali (Winter rice): Main Kharif crop, sown in June–July, harvested in November–December.
3. Boro (Spring/Summer rice): Grown in winter (using irrigation), harvested in April–May — common in West Bengal and Assam.

Varieties of rice grown in India: • Basmati: Long-grain aromatic variety; grown mainly in Punjab, Haryana, and western UP; prized globally. • Non-Basmati: Includes Ponni (Tamil Nadu), Sona Masuri (Andhra Pradesh/Telangana), Gobindobhog (West Bengal), etc. • IR-8: High-Yielding Variety introduced during Green Revolution.
