ABSTRACT
An experiment was conducted to reduce the entrance of arsenic on rice plant. Experiment consisted three different density of the trap plants viz. P1: No P. vittata (control); P2: four P. vittata plant per m2 and P3: eight P. vittata plant per m2. Inter planting of four P. vittata per m2 reduced 96.24 % and eight P. vittata per m2 reduced 97.01% arsenic accumulation into rice. Maximum yield was found from P2 (34.2 g per plant) which was statistically similar with P3 (32.9 g per plant) while minimum was found from P1 (30.0 g per plant). Highest amount of arsenic accumulation was found from P1 in rice grain (1.55 ppm), husk (5.57 ppm) and straw (39.78 ppm). Arsenic accumulation was found in rice grain (0.02 ppm in both P2 and P3), husk (0.60 and 0.58 ppm in P2 and P3 respectively) and straw (1.05 and 1.00 ppm in both P2 and P3 respectively). Concerning both yield of rice and arsenic concentrations in rice plant, it can be recommended to interplant four P. vittata plant per m2 area as a trap plant to reduce arsenic entrance into rice plant from soil which can keep away of arsenic pollution in food chain.
Key words: Arsenic, rice, Pteris vittata, inter-planting and trap plant
