Why do certain crops thrive in specific regions?

Correct Answer

Certain crops thrive in specific regions because of the interplay of multiple factors: climate (temperature, sunshine, and rainfall patterns), soil type (different soils have different nutrient compositions and water-holding capacities), availability of water (from monsoons or irrigation), and terrain (flat plains versus hilly slopes).

Each crop has specific requirements for these factors. For example, rice needs abundant water and grows well in tropical wet climates with alluvial soil, while wheat prefers cooler temperatures and grows in subtropical regions during the rabi season.

The chapter states that 'growing crops is dependent on several factors — the soil, the climate, the availability of water, the terrain' (Page 3).

Explanation

The chapter extensively discusses how India's varied geography and climate influence crop variety (Page 6). It explains that different regions receive different quantities of sunshine and rainfall, experience different temperatures, and have different soil types. The 15 agroclimatic zones help identify 'what, when, and how to grow different crops' (Page 7). The soil-crop linkages section (Page 11) further explains how crops are strongly influenced by soil type.

Solution Steps

  1. Climate factors include temperature, sunshine, and rainfall patterns that affect crop growth

  2. Soil type determines nutrient composition and water-holding capacity for different crops

  3. Water availability from monsoons or irrigation is essential for crop cultivation

  4. Terrain characteristics (flat plains vs hilly slopes) influence which crops can be grown

  5. Each crop has specific requirements — rice needs abundant water and alluvial soil in tropical wet climates

  6. Wheat prefers cooler temperatures and grows in subtropical regions during rabi season
