During the last six decades, Sri Lankan paddy production has systematically increased due to improved technology and enhanced cultivation. Along with this trend, there is also a year-to-year variation in harvest primarily due to rainfall variations. An analysis of these variations shows that during the global El Nino climatic episodes, the odds are that Yala harvest decreases and Maha harvest increases. During El Nino episodes, there is usually an increase in the rainfall from October to December which is the planting phase of the Maha season leading usually to an increase in paddy production. The 2002/ 2003 Maha was during an El Nino season and heavy rains fell during this period and it is likely that 2002/2003 bumper Maha crop was influenced by the El Nino event. Since the rise in paddy production was likely due to a climatic anomaly, it would be unwise to change agricultural policy to discourage paddy cultivation.
