Agroclimatic Zones

Broad geographic divisions based on major climatic variables, terrain, soil varieties, and vegetation types; India is categorized into 15 such zones to aid agricultural planning.

Southwest Monsoon

The seasonal wind pattern active from June to September that delivers widespread rainfall essential for growing kharif crops across northern and central India.

Northeast Monsoon

The wind system active from October to December that supplies seasonal rains to eastern and southern India, including coastal regions like the Coromandel and Malabar plains.

Kharif Season

The monsoon cropping season characterized by hot temperatures and heavy rainfall, featuring crops such as rice, maize, jowar, bajra, groundnut, and cotton.

Rabi Season

The winter cropping season characterized by cooler temperatures and lower water requirements, featuring crops such as wheat, barley, mustard, peas, and gram.

Zaid Season

The short summer cropping season occurring between the rabi harvest and kharif sowing, characterized by crops like watermelon, muskmelon, cucumber, and pumpkin.

Kedara, Haimana, and Graishmika

Traditional Sanskrit terms used before the adoption of Arabic terminology during Mughal times to denote wet crops (kharif), winter crops (rabi), and summer crops (zaid) respectively.

Soil

The thin, uppermost layer of the Earth's crust formed over centuries to millennia through the weathering of rocks and decay of organic matter, providing nutrients, water, and structural support for plants.

Humus

The dark organic material in soil produced through the decomposition of plant and animal tissues; it retains moisture, supplies essential nutrients, and takes its name from the Latin word for 'earth' or 'soil'.

Amarakosha

An ancient Indian Sanskrit lexicon that classifies agricultural soils into twelve distinct categories based on land fertility.

Weathering

The natural breakdown of rocks and minerals into fine soil particles through physical, chemical, or biological processes over time.

Silt

A fine, dust-like mineral sediment composed of particles larger than clay but smaller than sand, readily carried down by river systems from mountains to floodplains.

Bedrock

The solid, unweathered rock foundation from which parent material and upper soil layers originate through weathering and erosion.

Alluvial Soil

Highly fertile soil formed from silt, sand, and clay deposited by rivers flowing from mountains and plateaus, suited for crops like wheat, rice, sugarcane, and black gram.

Black Soil (Cotton Soil)

A fertile soil formed by the weathering of volcanic rocks that has high moisture-retention capacity and is well-suited for growing cotton.

Laterite Soil (Brick Earth)

A reddish, nutrient-poor soil formed under heavy rainfall where most soluble minerals leach away, leaving mainly iron and aluminium oxides that turn hard in hot dry weather.

Alpine Soil

A thin, rough, and rocky soil found in high-altitude mountain environments, formed by the repeated freezing and thawing of ice against exposed rock.

Soil Conservation

The management and protection of soil to prevent degradation, erosion, and nutrient loss, thereby sustaining long-term agricultural productivity.

Crop Rotation

The practice of cultivating different varieties of crops sequentially on the same land across different seasons to prevent the exhaustion of specific soil nutrients.

Contour Ploughing

The practice of ploughing across hill slopes following natural contour lines rather than up and down, which slows rainwater runoff and limits topsoil erosion.

Panchagavya

A traditional fermented biofertiliser made from five bovine products (cow dung, urine, milk, curd, and ghee) that enhances crop growth, boosts yield, and improves disease resistance.

Greenhouse

A transparent structure framed with glass or plastic that captures sunlight and thermal energy, creating a controlled environment for plant cultivation.

Rain-fed Agriculture

Agricultural practices that depend exclusively on rainfall for crop moisture rather than artificial irrigation systems.

Irrigated Agriculture

The practice of supplying water to crops using artificial canals, wells, pipes, or impoundments to enhance crop yields and reduce vulnerability to delayed or deficient monsoons.

Phad System

A traditional, community-managed irrigation system in Maharashtra that uses small diversion weirs and channels to direct river water to cultivated fields.

Bamboo Drip Irrigation

An indigenous irrigation technique practiced in northeastern India where water from uphill natural springs is transported through connected bamboo pipes directly to crop beds.

Kallanai

An ancient water diversion structure known as the Grand Anicut, constructed across the Kaveri River about 1,800 years ago by King Karikala to irrigate thousands of hectares.

Munsar Lake

An artificial 11th-century CE reservoir built at Viramgam, Gujarat, by Queen Minaldevi of the Chaulukya dynasty, framed by shrines demonstrating the sacred cultural value of water bodies.

Drip Irrigation (Trickle Irrigation)

A micro-irrigation system consisting of pipes and emitters that delivers water slowly and directly to plant root zones, conserving water by minimizing evaporation and runoff.

Sprinkler Irrigation

A pressurized irrigation method that sprays water into the air through nozzles, creating artificial precipitation over crops.

Beejamrit

A traditional seed-treatment paste formulated from cow dung, cow urine, and natural additives; endorsed by ICAR to prevent seed spoilage and shorten germination time.

Traditional Indian Seed Drill

An ancient agricultural tool that integrated three distinct tasks—furrow preparation, seed placement, and furrow closure—into a single mechanical pass.

Terrace Farming

The practice of carving flat, stepped platforms into steep hill slopes to create cultivable land, reduce water runoff, and prevent soil erosion.

Kulagar

A structured homestead farming system found in the Konkan Plains of Goa (from 'kul' meaning family and 'agar' meaning storehouse) where cash crops, fruits, spices, and food crops are grown with integrated irrigation around the home.

Gokrishi

A holistic indigenous farming method centered on cattle, where cows provide manure for organic fertiliser and bullocks supply animal power to plough fields.

Green Revolution

An intensive agricultural modernisation movement in India during the 1960s and 1970s that relied on High-Yielding Varieties (HYV) of seeds, synthetic fertilisers, chemical pesticides, increased irrigation, and mechanised farm equipment.

M.S. Swaminathan

The eminent agricultural scientist and Bharat Ratna recipient acclaimed as the chief architect of the Green Revolution in India.

Organic Farming

An eco-friendly agricultural system inspired by Indian Knowledge Systems (IKS) that avoids synthetic chemical inputs, relying instead on compost, seed cake, animal manure, and neem-based bio-pesticides.

Seed Cake

The dense residue that remains after oils have been extracted from seeds, commonly utilized as an organic fertiliser to enrich soil.

Sikkim

The world's first 100 percent organic state, having banned synthetic chemical fertilisers and pesticides in 2014 to transition entirely to natural farming practices.

Hydroponics

A soil-less cultivation method in which plants are grown in nutrient-rich water solutions with dissolved minerals provided directly to their roots in controlled environments.

Landholding

The specific area of agricultural land owned by an individual or family; in India, the average landholding size is approximately three-fourths of a hectare.

Hectare

A metric unit of land measurement equal to $10,000\,\text{m}^2$ (contrasted with an acre, which is approximately $4047\,\text{m}^2$).

Pradhan Mantri Fasal Bima Yojana

A government-sponsored crop insurance scheme that provides Indian farmers with affordable insurance coverage against harvest loss caused by adverse natural conditions.

Debt Trap

A severe financial condition where farmers take loans to cope with crop failure or high input costs and cannot repay them due to low income, leading an estimated 2,300 farmers every day to leave agriculture.
