The Weeds Control of a Novel Bioorganic Fertilizer and its Effects on Agronomic Traits of Rice

Bio-organic fertilizer (BIO) is usually used as one of effective solutions to control weeds and reduce environmental pollution in agricultural ecosystems.A novel BIO for weed control and nutrient supply was manufactured and field trials at three rice fields were conducted for two years to evaluate its effect.The novel BIO was found to be effective in controlling grass and broad-leaved weeds in rice fields, with an average rate of more than 80% weed suppression.In addition, the BIO treatments significantly increased rice yield (16.3-29.8%relative to control) and yield components (e.g., number of spikes per square meter, plant height, number of kernels per spike).Results from these field experiments have implications for farmers and government agencies in regard for accept ability of bio-organic fertilizer for biological weed control in rice cultivation.
