Abstract
The presence of weeds potentially interfereswith the growth of crops, especially on sago
plantations. The purpose of this research was to find out composition, Index of Similarity
and Index of Diversity of weeds in a sago plantation PT. National Sago Prima,Kepulauan
Meranti regency, Riau. The research was conducted in January 2016 - April 2016. A
quadrat sampling technique was carried out in four different location conditions, sago
plantation which were not burned, burned in 2014, burned in 2013and burned in 2012. Size
and number of plots were determined by plotting species-area curve. Based on the research
results, 25 weed species obtained were classified into 18 families of 4,444 individuals. The
results showed that the Index of Similarity of those burned locations had high
communities’ similarity, while between the burned locations and locations which were not
burned suggested otherwise. Based on Index of Diversity results, the 2014 burned location
had the highest diversity of 0,86 and the lowest value of Indexof Diversity was 0,06, found
on not burned location
