Cropping Patterns in Agriculture: Types, Systems & Examples

Cropping patterns define the yearly sequence and spatial arrangement of crops on a piece of land — the core decision every farmer makes to balance yield, soil health, and income. With field preparation and plant stand established (previous lesson), the next decision is what to grow, when, and in what combination.

Why Cropping Systems Matter

A rice-wheat farmer in Punjab grows two crops a year on the same plot, while a dryland farmer in Rajasthan may grow only pearl millet with an intercrop of moth bean. Both are following a cropping system -- the planned sequence and combination of crops on a given piece of land. Choosing the right system determines not just yield, but also soil health, income stability, and food security for millions.

Farming System

Before diving into cropping systems specifically, it helps to understand the broader concept of a farming system — the integrated whole that cropping is part of.

A farming system is a complex, inter-related matrix of soil, plants, animals, implements, labour, capital, and other inputs managed by the farm family. It represents the holistic integration of crop production with enterprises like dairying, fisheries, poultry, sericulture, and agroforestry for optimal resource utilisation.

Principles of Farming System

1. Risk minimisation through diversification
2. Use of end products from one enterprise as input in another (e.g., cattle dung for biogas and manure)
3. Recycling of wastes and residues
4. Integration of two or more enterprises
5. Optimum utilisation of all resources
6. Maximum productivity and profitability
7. Ecological balance
8. Employment generation
9. Increased input-use efficiency

Determinants of Farming System

Factor	Type	Examples
A -- Physical & Biological	Sets limits on what can be produced	Climate, soil type, topography, local varieties
B -- Endogenous Human	Within farmer's control	Family size, skills, preferences, farm size
C -- Exogenous Human	External influences	Market prices, government policy, credit, infrastructure

Components of Farming System

Dairying, Biogas plant, Sheep & goat rearing, Poultry, Fisheries, Bee-keeping (Apiculture), Sericulture, Agro-forestry -- each integrates with crop production for a diversified, resilient farm.

Cropping System

• The principles and practices of cropping and their interaction with farm resources, technology, and environment to suit regional/national needs. ^{FCI AGM 2021}
• Most common cropping system in India: Rice-based cropping system.

Cropping Pattern

• The yearly sequence and spatial arrangement of crops on a given area, considering soil, climate, crop efficiency, socio-economic factors, technology, and national agricultural policy.
• It is dynamic -- changes over space and time.

Major Cropping Patterns in India

Pattern	Key States	No. of Patterns	Most Prominent
(A) Rice-based	West Bengal, Uttar Pradesh, Bihar, Madhya Pradesh, Odisha, Andhra Pradesh, Tamil Nadu, Kerala; Non-traditional: Punjab, Haryana, Western Uttar Pradesh	30	Rice-Wheat (Indo-Gangetic Plains)
(B) Wheat-based	Traditional wheat areas; Non-traditional: North-West India	19	Rice-Wheat, Pigeon pea-Wheat
(C) Kharif Sorghum	Maharashtra, Madhya Pradesh, Karnataka, Gujarat, Rajasthan, Andhra Pradesh	17	--
(D) Rabi Sorghum	Maharashtra, Karnataka	13	--
(E) Pearl millet	Gujarat, Rajasthan (arid/semi-arid tropics)	20	Bajra-based rotations
(F) Maize	Uttar Pradesh, Bihar, Rajasthan, Madhya Pradesh, Punjab	12	--
(G) Cotton	Gujarat, Maharashtra, Andhra Pradesh	16	--
(H) Chickpea/Pulses	Non-traditional: Karnataka, Andhra Pradesh, Tamil Nadu	--	--
(I) Groundnut	Gujarat, Karnataka, Andhra Pradesh, Tamil Nadu (rainfed)	9	--

Rice-Wheat dominates the Indo-Gangetic Plains (Zones 3-6) because rice thrives in hot wet kharif and wheat in cool dry rabi — the same alluvial soil serves both.

Multiple Cropping

Multiple cropping is the primary strategy for intensifying production on limited land. It can be done by growing crops one after another (sequential) or simultaneously (intercropping). Understanding these distinctions is critical — exams often test sequential vs intercropping vs mixed cropping.

Growing two or more crops in a year on the same land to intensify production in both time and space.

(A) Sequential Cropping

• Two or more crops grown one after another on the same field in a year. No overlap in growth periods.
• Intensification in time dimension only.
• No inter-crop competition; farmer manages one crop at a time.
• Double cropping (Rice-Potato), Triple cropping (Rice-Potato-Groundnut).

(B) Intercropping

• Two or more dissimilar crops grown simultaneously on the same land with base crop in distinct row arrangement.
• Intensification in both time and space.

Advantages: Yield stability, better resource use, weed/pest control, mutual support, erosion control.

Disadvantages: Adverse competition, allelopathic effects, obstruction to machinery.

Four Types of Intercropping

Type	Arrangement	Use
Mixed intercropping	No distinct row arrangement	Labour-intensive subsistence farming
Row intercropping	Distinct rows for each crop	Mechanised agriculture
Strip intercropping	Wide strips for independent cultivation	Large-scale farms
Relay intercropping	Growth cycles overlap; 2nd crop planted before 1st is harvested	Extending growing season

(C) Relay / Overlapped Cropping

• Inter-planting 2nd crop before harvest of maturing 1st crop.
• Example: Potato planted before maize harvest; Radish sown before potato harvest.
• Paira (Bihar/WB) and Utera (MP) cropping = sowing lathyrus or lentil before rice harvest to use residual moisture in lowland.

---

Mixed Cropping

Mixed cropping is conceptually different from intercropping — it prioritises insurance against failure over systematic resource optimisation. It is most common in dryland areas where monsoon uncertainty makes sole cropping risky.

• Two or more crops grown simultaneously, seeds may be mixed or in alternate rows.
• Crops should have different durations and be harvested at different times. ^{NABARD 2021}
• Main objective: Insurance against crop failure in aberrant weather.
• Studied scientifically first by La-Flitze (1929).
• Common in dryland areas of India; sowing by broadcasting.

Intercropping vs Mixed Cropping

Aspect	Intercropping	Mixed Cropping
Objective	Utilise space between main crop rows	Insurance against total crop failure
Crop status	Clear main + subsidiary crop	All crops have equal status
Duration	Subsidiary = shorter duration	Crops of similar duration
Sowing	Both in rows	May be broadcast or in rows

Intercropping uses defined rows so mechanized harvesting remains possible. Mixed cropping broadcasts seeds together because the dryland farmer's priority is insurance — if one crop fails, the other might survive.

Other Cropping Concepts

Beyond multiple and mixed cropping, several specialised cropping concepts appear frequently in exams. Each describes a specific way of managing crops on the same land — from ratooning (re-growing from stubble) to multistorey cropping (layering crops by height).

Concept	Definition	Example
Sole Cropping	One crop variety grown alone at normal density	Wheat sole crop
Monoculture	Same crop in same season (space sequence)	Rice every kharif
Monocropping	Same crop year after year (time sequence) -- risks soil degradation	Continuous rice-rice
Ratooning	Fresh crop from stubbles/suckers without replanting; matures earlier	Sugarcane ratoon crop
Mixed Farming	Crop production + livestock + poultry + fisheries on same farm	Rice + dairy + fish pond
Multistorey Cropping	2+ crops of different heights on same field	Sugarcane + Mustard + Onion (Karnataka, Kerala)
Parallel Cropping	Crops with different growth habits, zero competition	Urd/Moong + Maize
Companion Cropping	Both intercrops yield = their sole crop yield	Mustard + Sugarcane
Synergetic Cropping	Both crops yield higher than sole crop	Sugarcane + Potato
Staggered Planting	Sowing spread over optimum period to reduce risk or extend market supply	--
Live Mulch	Planting food crop into living cover crop without tillage	--

Crop Rotation

Rotation is one of the oldest and most effective soil management practices. By alternating between exhaustive crops (cereals) and restorative crops (legumes), farmers maintain fertility, break pest cycles, and reduce disease pressure without chemicals.

The repetitive cultivation of an ordered succession of crops on the same land. Crop rotation is the reverse of land rotation — the crop is rotated, not the land.

Principles of Crop Rotation

1. Exhaustive crop followed by restorative crop — cereal (heavy feeder) followed by legume (N-fixer).
2. Deep-rooted crop followed by shallow-rooted crop — uses different soil layers.
3. Crops of different families — breaks host-specific pest and disease cycles.
4. Cash crop followed by food/fodder crop — balances farm economy.
5. Water-demanding crop followed by drought-tolerant crop — conserves moisture.

Common Indian Crop Rotation Examples

Rotation	Region	Logic
Rice → Wheat	Punjab, Haryana, UP	Most dominant; kharif-rabi; high productivity
Rice → Lentil/Chickpea	Eastern India	Legume restores N after rice
Maize → Wheat → Cowpea (fodder)	North India	3-crop rotation; cowpea fixes N
Cotton → Jowar → Groundnut	Maharashtra	Breaks cotton bollworm cycle
Sugarcane → Wheat → Moong	UP	Exhaustive → cereal → restorative
Bajra → Mustard → Moong	Rajasthan	Dryland 3-year rotation

Example of pest cycle break: Rice stem borer (Scirpophaga spp.) survives in rice stubble. If rotated with wheat → legume, the pest loses its host, population crashes.

Advantages of Crop Rotation

1. Prevents soil depletion — different crops draw different nutrients
2. Maintains soil fertility — legumes fix atmospheric N₂ (50–200 kg N/ha/yr)
3. Controls weeds — different crop canopies shade out different weed species
4. Breaks pest and disease cycles — host-specific pathogens starve without host
5. Reduces chemical inputs — less need for pesticides/fertilisers
6. Reduces soil erosion — continuous soil cover
7. Increases overall productivity — Rotation yield > monocropping yield over time

Disadvantages of Crop Rotation

1. Complex planning — needs knowledge of crop families and sequences
2. Market linkage needed — rotating crops must all be marketable or usable
3. Equipment and skill requirements vary across crops in the rotation

Land Equivalent Ratio (LER)

• LER = relative land area under sole crops needed to produce the same yields as intercropping.
• Given by Willey, R.W.
• Example: La = 0.70, Lb = 0.40 --> LER = 1.10 --> intercropping is 10% more land-efficient.

---

Cropping Intensity

• Cropping Intensity (CI) = (Total cropped area / Net cultivated area) x 100
• India's cropping intensity: 143%
• Highest cropping intensity: Punjab
• Cropping Index = number of crops per year x 100. E.g., Cowpea-Rice-Wheat = 300%.

Important Agronomical Crop Terms

These specialised terms describe the role a crop plays within a cropping system — whether it suppresses weeds, traps pests, restores fertility, or serves as insurance. Exams frequently test the definition-example pairs.

Term	Definition	Examples
Smother crops	Suppress weeds by dense foliage, quick growth	Barley, Mustard, Cowpea
Nurse crops	Nourish main crop by N-fixation / OM	Cowpea with cereals
Guard / Barrier crops	Protect main crop from wind/pests	Mesta around Sugarcane; Sorghum around Cotton
Augmenting crops	Increase yield of main crop	Mustard with Berseem
Alley crops	Grown in alleys of trees for fertility and erosion control	Pulses between Poplar rows
Catch / Contingent crops	Substitute when main crop fails	Chickpea, Cowpea, Bajra
Cover crops	Protect soil from erosion	Groundnut, Chickpea, Sweet potato
Trap crops	Trap harmful insects/nematodes/weeds	Castor in Cotton for army worm
Cash crops	Grown for sale	Sugarcane, Cotton, Tobacco, Jute
Complementary crops	Each crop benefits the other	Jowar + Lobia
Ley crops	Grown for grazing/harvesting for livestock	Berseem + Mustard
Break crops	Pulse/oilseed instead of cereals to break disease cycle	Lentil or Mustard instead of Wheat
Exhaustive crops	Feed heavily on soil nutrients, deplete fertility	Sorghum, Tobacco, Sugarcane
Restorative crops	Enrich soil while providing harvest (fix nitrogen)	Legumes — Gram, Moong, Berseem
Dobari crops	Crop grown on residual moisture after rice harvest (same concept as Paira/Utera)	Lathyrus, lentil in eastern India

A smother crop is the organic farmer's alternative to herbicides — it physically shades out weeds through rapid dense growth.

Indices in Cropping Systems

Index	Definition
LER	Land needed under sole crop to match intercrop yield. LER > 1 = advantage.
Relative Crowding Coefficient (RCC)	Replacement series: more/less yield than expected in mixture
Aggressivity	Relative yield increase of crop A vs crop B in mixture
Cropping Intensity	(Total cropped area / Net cultivated area) x 100
Multiple Cropping Index	Total area cropped in a year / Land area available x 100
Crop Equivalent Yield	Intercrop yields converted to equivalent of one crop using price ratios

Seed Measurement Terms

Term	Definition
Seed Index	Weight of 100 seeds — used to compare seed size across varieties
Test Weight	Weight of 1000 seeds — Tobacco has the lightest (0.25-0.30 g)

---

Additive vs Replacement Series

Aspect	Additive Series	Replacement Series
Design	Base crop at full population + intercrop added	Both crops share combined population equal to sole crop
Population	More than sole crop	Equal or less than sole crop
Efficiency	More efficient	LER often < 1
Example	Sugarcane (full) + Potato (additional)	Maize replacing some sorghum rows

---

Cropping Scheme

The plan for growing crops on individual plots to get maximum return without impairing soil fertility.

Cropping System Selection Guide for Different Agro-Climatic Zones

Which cropping system to recommend? Match zone + irrigation + soil:

Zone / Situation	Recommended System	Cropping Intensity	Why It Works
NW India (Punjab, Haryana) — canal-irrigated	Rice-Wheat	200%	Assured irrigation; but causes groundwater depletion + residue burning problem
NW India — diversification needed	Rice-Potato-Wheat or Rice-Mustard-Moong	250-300%	Breaks rice-wheat monotony; adds income; legume fixes N
Eastern India (Bihar, WB) — medium land	Rice-Lentil/Chickpea	200%	Rabi pulse uses residual moisture; improves soil N
Central India (MP, Rajasthan) — rainfed	Soybean-Wheat	200%	Soybean fixes N; both crops suit Vertisols
Dryland — single season only	Pearl millet + intercrop (cowpea/pigeon pea)	100-150%	Drought-tolerant base crop + legume safety net
Sugarcane belt (UP, Maharashtra)	Sugarcane + intercrop (potato/wheat in autumn)	~150%	Long-duration sugarcane allows early intercrop for extra income
Perennial systems — small holdings	Agroforestry (fruit trees + field crops + livestock)	Multi-tier	Year-round income; risk diversification; ecological sustainability

Key principle: A good cropping system maximizes cropping intensity (% of land under crop per year) while maintaining soil health through legume inclusion and residue management. The best system for any farm depends on water availability, soil type, and market access.

Exam-critical distinction: Cropping Pattern = what crops, what sequence. Cropping System = pattern + management practices. Cropping Intensity = (Gross Cropped Area / Net Sown Area) × 100. India's average cropping intensity is approximately 140%.
