Management of Singapore Daisy (an Invasive Weed) through Utilisation

Singapore daisy is a perennial invasive weed of Kerala having the potential to adversely affect the environment and biodiversity. One of the possible methods for the management of invasive weeds is through their utilisation. The study explored the potential of Singapore daisy for phytoremediation of contaminated soils along with its potential as a fodder crop. The results revealed that the invasive plant has the potential for phytoextraction (BAC and TF >1) of cadmium and lead; phytostabilisation (BCF>1; TF<1) of cadmium, arsenic, chromium and lead. Analysis of proximate principles of Singapore daisy revealed that the nutritive value was comparable to that of common fodder crops (also, K/Ca+Mg ratio was 1.19) cultivated in Kerala. However, since the plant has phytoremediation potential, it cannot be recommended as a fodder crop unless it is growing in uncontaminated soil.
