3. Climate Impacts: Shifting Seasons and Yield Fluctuations
In recent years, Indian farmers have been witnessing significant changes in the climate, which directly impact the yield of key crops like potato, onion, and garlic. The most noticeable shifts are in rainfall patterns, temperature variations, and the increasing frequency of weather extremities across major agricultural belts from Punjab to Maharashtra and Tamil Nadu.
Unpredictable Rainfall Patterns
Traditionally, the onset of monsoon has been a reliable indicator for sowing times. However, erratic rainfall—either heavy downpours or prolonged dry spells—has become more common. In states like Uttar Pradesh and West Bengal, excessive pre-monsoon rains often delay potato planting, while insufficient winter rains hinder the growth phase of onions and garlic. These anomalies force farmers to adapt their schedules, sometimes risking sub-optimal yields.
Temperature Extremes Affecting Growth Cycles
The rise in average temperatures during both summer and winter months is another concern. Potatoes thrive in cool conditions; higher temperatures during tuber formation result in smaller yields and increased vulnerability to pests like the potato tuber moth. Onion and garlic, typically planted as rabi crops, face bolting—a premature flowering—when exposed to unexpected warmth during their vegetative stage. This reduces bulb size and overall market value for cultivators from Nashik to Bengaluru.
Weather Extremities: A Growing Threat
Heatwaves during late spring or sudden cold snaps in December can devastate entire fields within days. For example, unseasonal hailstorms in Madhya Pradesh have repeatedly damaged young potato shoots, while flash floods in Odisha wash away newly sown onion seeds. Such unpredictable events disrupt the delicate timing required for optimal sowing, growing, and harvesting cycles.
Adapting to New Realities
Indian farmers are increasingly turning to adaptive strategies—such as staggered sowing dates or drought-resistant seed varieties—to cope with these climatic uncertainties. However, these solutions come with added costs and risks. As seasons continue to shift unpredictably due to climate change, ensuring steady yields of potatoes, onions, and garlic remains a major challenge for India’s farming community.
