Abstract

The North West Selangor Integrated Agriculture Development Agency (NWS-IADA) has the most productive agricultural land in Selangor. This is partly because of the inherent high fertility of the soils, and the moderate variable climate. However, with the increasing global concern about climate impacts, there is a need to examine the issue and this article presents a study that examined the relative importance of climate influences on the paddy production rate over 28 years (1980-2008). Data collection involved compiling and analyzing climate records from MARDI Tg. Karang auxiliary station (Station no. 44325, 24m m.s.l) at the coordinates of N 03° 27' 17" E 101° 09' 24". The results indicate that the average rainfall recorded was 1, 765 mm which is similar to the national rainfall trend. Meanwhile, the daily humidity varied between 94 - 96% (8.00 AM) and around 70% (2.00 PM) while the sunshine hours ranged between 2.3 to 9.5 hours. A correlation analysis between the production yield and climatic data at the studied area for the year 2000 - 2008 showed that for precipitation, rainfall is redundant during the main season while during the off season it bears direct effect on the production yield with R2 value of -0.293 and 0.1715, respectively. Sunshine hours and temperature demonstrate their importance to production yield as suggested by their respective R2 values.
