 ABSTRACT

An analysis was carried out to study the impact of El-Nino and La-Nina on regional variability of rainfall (1980-2011) in Punjab. During the El-Nino year in Hoshiarpur, Patiala, Ludhiana, Sangrur, Gurdaspur, Amritsar and Bathinda in which no significan impact on wheat yield was observed. During La-Nina years Hoshiarpur, Patiala, Ludhiana, Sangrur, Gurdaspur, Amritsar and Bathinda in which yield was more then 60% chances are higher compared to average. Overall results the El-Nino and La-Nina episodes not much more effect to wheat yield in Punjab because there less dependency on monsoon, artificial irrigation and other water resources are available.
