Topic: Factors responsible for the location of primary, secondary, and tertiary sector industries in various parts of the world (including India)

Q2. What role do agro-climatic zones play in determining regional cropping patterns? Analyse how crop calendar modifications can affect inter-seasonal crop cycles. (10 M)

Difficulty Level: Medium

Reference: IE

Why the question:
Punjab Chief Minister announced that the paddy transplantation season will commence on June 1 this year. This marks a shift, with transplantation beginning from June 11 onwards last year and never initiating as early as June 1 since 2009.

Key Demand of the question:
It asks for an explanation of how agro-climatic zones determine cropping choices and an analysis of how changing crop calendars impacts inter-seasonal agricultural dynamics.

Structure of the Answer:

Introduction:
Brief definition of agro-climatic zones and their role in regional crop planning, possibly linked to ICAR or Planning Commission zonation.

Body:

  • Role of agro-climatic zones: Discuss how rainfall, temperature, soil, and irrigation determine regional crop suitability and diversity.
  • Impact on inter-seasonal crop cycles: Explain how advancing or delaying crop calendars affects sowing windows, soil recovery, labour availability, and stubble management.

Conclusion:
Emphasize the need for integrating agro-climatic insights with dynamic crop calendars, supported by technology and localized advisories.
