India's summer (zaid) crops show resilience to current heatwaves but prolonged high temperatures could reduce yields by 5.34% of total foodgrain production, raising concerns over agricultural costs and food inflation.

Key points

Zaid crops like maize, moong, and groundnut are currently resilient due to timely irrigation, but prolonged heatwaves may reduce yields and quality, impacting 5.34% of India's total foodgrain production.

ICAR warns that extended heat stress could increase irrigation needs, accelerating soil moisture loss and raising production costs for farmers.

[GS3-Economy] Rising temperatures may elevate input costs (electricity/diesel for pumps), squeezing farm margins despite increased sowing area for pulses and oilseeds.

IMD forecasts predict above-normal heatwave days in April-June, particularly affecting northwest, central, and peninsular India, with temperatures reaching 45.6°C in Uttar Pradesh.

Summer crop area increased marginally to 7.23 million hectares in 2026, driven by pulses (+96,000 ha for black gram) and oilseeds (+131,000 ha for groundnut), but remains below last year's 8.39 million hectares.

Rice acreage declined to 3.06 million hectares (from 3.23 million ha in 2025), while coarse cereals like maize expanded by 100,000 hectares, reflecting a shift toward drought-resistant crops.

[GS1-Geography] Heatwave patterns show regional disparities, with western Himalayas and northeast India below 36°C, while northwest and central regions face extreme temperatures above 40°C.

India's central pool foodgrain stocks remain comfortable at 60.4 mt (vs. buffer norm of 21.04 mt), but localized crop losses could trigger price volatility in pulses and oilseeds.

Way Forward: Accelerate adoption of heat-resistant crop varieties through ICAR research, expand micro-irrigation under PMKSY, and integrate real-time weather data with agricultural advisories to mitigate climate risks.

Key terms

Heatwave

Defined by IMD as temperatures exceeding 40°C in plains or 30°C in hills, with a 4.5°C–6.4°C deviation from normal. Heatwaves impact crop phenology, soil moisture, and rural livelihoods, a key concern for GS3 Environment and GS2 Social Justice (vulnerable farmers).

Zaid Crops

Short-duration crops grown between rabi (winter) and kharif (monsoon) seasons, including maize, moong, and groundnut. They account for 5.34% of India's foodgrain production and are vulnerable to heat stress, making them critical for GS3 Agriculture topics on climate resilience.

Indian Council of Agricultural Research (ICAR)

The apex body for coordinating agricultural research and education in India, under the Department of Agricultural Research and Education (DARE). It develops heat-tolerant crop varieties and sustainable farming practices, directly relevant to GS3's 'Technology Missions in Agriculture'.

India Meteorological Department (IMD)

The national agency responsible for weather forecasting and monsoon prediction. Its heatwave warnings (like the April-June 2026 alert) inform agricultural contingency plans, linking GS1 Geography (climate zones) and GS3 Disaster Management.
