Effect of Etlingera coccinea crude extract as bio-weedicide against weedy rice (Oryza sativa complex) / Nurfitri Harman

Etlingera coccinea is herb plant that is used and consumed by the indigenous ethnics in Borneo. This study pursued the possible allelopathy potential of E. coccinea as a new bio-weedicide in combating the growth of weedy rice (Oryza sativa complex). The application of synthetic herbicide endorses th...
