Crop combination in India represents the systematic arrangement of different crops grown together in specific geographic regions, reflecting the complex interplay of environmental conditions, economic factors, cultural preferences, and technological capabilities. This agricultural practice involves the strategic selection and spatial organization of multiple crops within farming systems to optimize land use, minimize risks, and enhance overall productivity. Understanding crop combinations is essential for comprehending India’s agricultural diversity, as different regions have evolved distinct cropping patterns adapted to their unique agro-climatic conditions and socio-economic circumstances.
The concept of crop combination extends beyond simple crop rotation or intercropping to encompass the dominant cropping systems that characterize different agricultural regions. These combinations reflect centuries of agricultural adaptation and represent rational responses to environmental constraints, market demands, and resource availability. Crop combination analysis helps identify regional agricultural specializations, understand land use efficiency, and develop appropriate agricultural policies for different zones.
India’s vast territorial expanse and diverse agro-climatic zones support numerous crop combinations, ranging from rice-wheat systems in the northern plains to cotton-based combinations in peninsular India and plantation crop systems in the Western Ghats and northeastern regions.

Theoretical Framework of Crop Combination
Crop combination analysis employs various methodological approaches to identify and classify the dominant cropping patterns in different regions. The Weaver’s method represents one of the most widely used techniques, calculating theoretical combinations and comparing them with actual crop distributions to determine the best-fit combination for each region.
Statistical measures including standard deviation calculations and percentage analysis help identify primary, secondary, and tertiary crops within regional combinations. The method considers the relative importance of different crops based on their area coverage rather than their economic value or production quantity.
Crop combination regions are delineated based on similarity in cropping patterns, creating homogeneous agricultural zones that share common characteristics in terms of dominant crops and farming systems. These regions often transcend administrative boundaries, reflecting natural and economic factors rather than political divisions.
Diversification indices measure the degree of crop diversification within combinations, indicating whether regions practice specialized monoculture or diversified agricultural systems. Higher diversification generally indicates reduced risk and greater stability in agricultural production.
Historical Evolution of Crop Combinations
Pre-Colonial Period
Traditional Indian agriculture developed region-specific crop combinations based on local environmental conditions and subsistence requirements. Indigenous knowledge systems guided crop selection and combination development, creating sustainable agricultural practices adapted to local conditions.
