Weed control is essential to improve plant productivity under an organic farming system. This practice often leads to shifting of weed species. The experiment confirmed that two-month solarization treatment brought about the alteration of weed species, but the number of weed species was not significantly different, approximately fifteen species for each treatment. Solarization treatment led to weed shifting and dominance from grass to broadleaf weeds. Red plastic mulch shifted Blumea lacerna dominance to Ricardia brasiliensis at 0-5 cm depth. Meanwhile, at 10-15 cm soil depth, the dominance of Eleucine indica was shifted into Bidens pilosa. Mulch treatment substantially reduced the number of weed population to the depth of 15 cm from the soil surface. After two months of solarization, clear plastic mulch is the most effective to reduce weed dry weight. Solarization significantly decreased weed dry weight by approximately 30, 60 and 65 % in treatments using silver black, black, and clear plastic mulch respectively in comparison to the control.
