IMD REPORT: GEOGRAPHY

NEWS: Warm February could hurt wheat, fruit, vegetables, says IMD

WHAT’S IN THE NEWS?

The IMD forecasts a warmer-than-normal February 2025 in northern India with below-normal rainfall, potentially impacting Rabi crops like wheat, mustard, and horticultural produce. Weak La Niña conditions in the Pacific Ocean are contributing to these climatic anomalies.

1. IMD’s February 2025 Weather Forecast

  • Above-normal temperatures: Expected across northern India due to changing atmospheric patterns.
  • Below-normal rainfall: Expected in the northern states, impacting soil moisture and crop health.
  • Night temperatures:
  • Above normal in most regions of India.
  • Near normal in northwest India & southern peninsula.
  • Day temperatures:
  • Above normal in most regions.
  • Below normal in parts of west-central and southern India.

2. Impact on Agriculture

A. Wheat (India’s Major Rabi Crop)

  • Life cycle: Sown in October–December, harvested February–April.
  • Affected states:
  • Punjab, Haryana, Rajasthan: High temperatures reduce grain filling, leading to lower yield.
  • Uttar Pradesh, Madhya Pradesh: Less impact due to possible rainfall, which can mitigate temperature rise.
  • Critical impact stage:
  • Flowering & grain-filling stage (February–March).
  • If temperatures rise above 25°C, grain size and quality reduce significantly.
  • Economic impact:
  • Lower yields could increase domestic wheat prices.
  • May impact government procurement and food security under schemes like PM Garib Kalyan Anna Yojana.

B. Mustard (Edible Oil Crop) & Chickpea (Pulses)

  • Growing pattern:
  • Mustard and chickpea mature between February–April.
  • Rising temperatures lead to early maturity, affecting grain size & oil content.
  • Affected states:
  • Mustard: Rajasthan, Uttar Pradesh, Haryana.
  • Chickpea: Madhya Pradesh, Maharashtra, Rajasthan.
  • Economic impact:
  • India depends on imports for edible oil—low mustard yield could increase import dependency.
  • Chickpea is a staple pulse; reduced output can cause higher market prices.

C. Horticultural Crops (Apples & Stone Fruits)

  • Effect of warm temperatures:
  • Early flowering in apples & stone fruits like peaches, plums, apricots.
  • Poor fruit setting leading to lower quality & yield.
  • Major producing states: Jammu & Kashmir, Himachal Pradesh, Uttarakhand.
  • Economic impact: Reduced supply may increase fruit prices in domestic markets.

3. Climatic Context – Weak La Niña Conditions

A. What is La Niña?

  • Definition: A phase of El Niño-Southern Oscillation (ENSO) affecting global climate.
  • Key Feature:
  • Stronger trade winds (east to west) push warm waters to the western Pacific.
  • Cooler waters upwell in the eastern Pacific, leading to below-normal sea surface temperatures.

B. La Niña’s Impact on India

  • Normally, La Niña brings cooler temperatures & higher rainfall.
  • However, weak La Niña conditions this year are leading to:
  • Less rainfall in northern India.
  • Above-normal temperatures affecting agriculture.
  • Possible heatwaves in March & April.

4. Crop-Specific Climate & Soil Requirements

A. Wheat

  • Temperature: 10°C–25°C.
  • Soil: Well-drained loamy/clayey soil.
  • Major States: Uttar Pradesh > Punjab > Haryana.
  • India’s Rank: 2nd largest wheat producer globally.

B. Mustard

  • Temperature: 10°C–25°C.
  • Soil: Well-drained sandy loam.
  • Major States: Rajasthan > Uttar Pradesh > Haryana.
  • Significance: Primary edible oil source in India.

C. Chickpea

  • Temperature: 10°C–25°C.
  • Soil: Well-drained loamy.
  • Major States: Madhya Pradesh > Maharashtra > Rajasthan.
  • Significance: Vital protein source in India.

D. Apple & Stone Fruits

  • Temperature: 21°C–24°C (cold winters essential).
  • Soil: Well-drained loamy soil with high organic content.
  • Major States: Jammu & Kashmir > Himachal Pradesh > Uttarakhand.
  • Significance: Key horticultural crops supporting local economies.
