(1) Field experiments were conducted at Taoyuan and Taipei areas to compare the fertilizer effect of PCP-urea with that of urea. The nitrification inhibitory effect of PCP-urea was also tested in the laboratory.
(2) With the same rate of nitrogen, PCP-urea gave a slightly higher grain yield than urea in the experiment, which might be attributed to both the nitrification inhibitory and the weed controlling effect of PCP-Na cantained in PCP-urea. migh be attributed.
(3) Nitrification is suppressed by PCP-urea, which is regarded favorable for the availability of nitrogenous fertilizer to the rice plant under water logged condition, as well as the ammonification of urea itself is also affected.
(4) Rice plants were injured by PCP-urea, however within the rate of 10 kg/ha, the plants were soon recovered.
