Write down the agronomic measures for climate-resilient crop production in rainfed areas.
Rainfed agriculture covers nearly 60% of cultivated land in India and remains highly vulnerable to climatic risks. Building climate resilience in these areas requires agronomic measures that optimize resource use and reduce production uncertainties.
Agronomic measures:
Drought-tolerant varieties: Adoption of short-duration and stress-tolerant crops like pearl millet, sorghum, pigeon pea, and groundnut ensures yield stability.
Diversification: Intercropping cereals with pulses or oilseeds reduces risk and improves soil fertility.
Soil moisture conservation: Practices such as contour bunding, mulching, and reduced tillage help conserve soil water.
In situ water harvesting: Farm ponds and check dams improve supplemental irrigation availability.
Nutrient management: Use of integrated nutrient management (INM) with biofertilizers and organic manures maintains soil productivity.
Cropping calendars: Adjusting sowing windows as per monsoon onset helps avoid crop failures.
Agroforestry integration: Planting trees on field boundaries reduces evapotranspiration, provides fodder, and improves carbon sequestration.
Pest and disease management: Resistant varieties and biological control methods minimize losses under changing climates.
Livelihood support systems: Combining farming with livestock, poultry, or horticulture ensures resilience in income.
Weather-based advisories: ICT tools and mobile-based services help farmers take real-time decisions on sowing and irrigation.
Conclusion: Climate-resilient agronomy in rainfed areas must integrate scientific innovation with traditional knowledge. Such strategies not only reduce the impact of climate change but also enhance food security and rural income.
