Potential of extracts of Ficus hispida linn for controlling germination and Growth of Weed in Rice Field for Increase the value of biodiversity and its sustainable use

Abstract

The potential of extracts of the Ficus hispida Linn to inhibit germination and growth of barnyardgrass (Echinochloa crus-galli), a common weed in rice. The bark, leaves and fruit of F. hispida isolated by the Maceration and extracted by the polarity of the solvent (Sequential Extraction) with organic solvents such as hexane, ethyl acetate and methanol, when each part of the crude extract was tested the type of phytochemical, tested for germinate inhibition, root length inhibition, stem length inhibition and dry weight inhibition of barnyardgrass and selected extracts with highest inhibition to separation using column chromatography, the fractions tested repeating. The results showed that 1. Crude methanolic extracts from the bark, leaves and fruit of barnyardgrass at a concentration of 3,000 ppm showed highest inhibited percentage of germinate inhibition, root length inhibition, stem length inhibition and dry weight inhibition. 2. Fractions methanolic extracts from the bark, leaves and fruit of barnyardgrass on a separate with column chromatography found that fractions extracts F5, F8 and F2 showed highest inhibited percentage of germinate inhibition, root length inhibition, stem length inhibition and dry weight inhibition.
