The aim of the procedure undertaken in 2014 was to calculate the concentration of Chlorophyll a, Chlorophyll b, total chlorophyll (a and b) and Chlorophyll (a/b) ratio in five ages (17, 47, 77, 107, 145) days from planting date, in leaf of Paddy that’s was grown in three sites has different concentration of Chromium., two fields (field 1 and 2) near the ultrabasic soil are located in Ranau, Sabah, and the other field (Field 3) taken as control is at the UKM experimental plot Paddy field in peninsular of Malaysia for the year 2014. The plant species used in the present investigation is Sarwak merah. The intention was to evaluate the effects of Chromium in conjunction with the relative age of the plant. The output parameter were sensitive to increase the Chromium concentration and age of paddy plant, the result showed significant differences in sites and age of Paddy plant, The most dramatic effect on both types of Chlorophyll, a and b and by extension therefore, total Chlorophyll was at the Ranau sites, which has high levels of Chromium specially Ranau field 1. While the lowest effects were recorded at the UKM experimental plot Paddy field in peninsular of Malaysia. Chlorophyll a, Chlorophyll b and total chlorophyll (a and b) declined progressively with increasing concentrations of chromium and age of Paddy plant, while the Chlorophyll (a/b) ratio was increased slightly with increasing chromium concentration and age of plant also.
