Abstract

An experiment was conducted in with two insecticides, phorate and carbofuran at rates of 10.0 and 16.5 kg ha-1 respectively, to investigate its effect on the availability of nitrogen in rhizosphere soils of rice (Oryza sativa L., variety IR-50). Application of the insecticides stimulated the availability of nitrogen in the rhizosphere soils, and the stimulation was more pronounced with phorate as compared to carbofuran. The residue of Carbofuron and phorate was detected below maximum residue limit of 0.1 mg kg-1 in grain after harvest.
