Evaluates the impact of real-time contingency measures on drought resilience in rainfed agriculture, indicating significant yield improvements.

Key Points

The study aims to evaluate the effectiveness of real-time contingency measures (RTCM) in combating drought in vertisols during the rainfed cultivation of Sorghum K12.
Conducted over five cropping seasons from 2019 to 2024
Implemented climate-resilient technologies including ridge-furrow planting and foliar sprays
Assessed dryness and wetness using the rainfall-to-pan evaporation ratio
Monitored soil moisture availability using Percent Available Soil Moisture (PASM)
Grain yield increased by an average of 45.6% under RTCM compared to control
Rainwater productivity improved from 0.54 to 0.65 kg/m³
Benefit-cost ratio increased from 2.02 to 3.06, showing economic viability
Yield stability was maintained even during low rainfall years
