Analysis of humidity indices to assess the impact of rainfall regimes on rice yield in the Anuradhapura Region of Sri Lanka

Year: 2025

Type: article

Abstract: The study examines the impact of agrometeorological conditions, particularly rainfall patterns, on rice yield over the past 30 years in the Anuradhapura Province of Sri Lanka. Anuradhapura is one of the primary rice-growing regions in the country. Long-term data on rice yield †and humidity indices were analysed. The island's climate, especially seasonal monsoon rainfall, significantly influences rice production. Changes in monsoon patterns, rainfall regimes, and air temperature directly affect rice yield and food security. Favourable weather conditions for rice cultivation and yield improvement have been identified.
