In a 2-year lysimeter experiment, the effect of urea-N in the presence of the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) on the yield and nitrate uptake of flooded and nonflooded rice was examined in comparison with N-fertilized and unfertilized plots. Results show that although DMPP doesn’t increase either the dry matter at different stages of development or the mean grain yield, it may improve grain quality reducing markedly NO3-N concentration. The positive effect of DMPP on grain quality was evident in both irrigation systems but it was especially pronounced in flooded conditions where PO4-P content significantly increased

Abstract

In a 2-year lysimeter experiment, the effect of urea-N in the presence of the nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) on the yield and nitrate uptake of flooded and nonflooded rice was examined in comparison with N-fertilized and unfertilized plots. Results show that although DMPP doesn’t increase either the dry matter at different stages of development or the mean grain yield, it may improve grain quality reducing markedly NO3-N concentration. The positive effect of DMPP on grain quality was evident in both irrigation systems but it was especially pronounced in flooded conditions where PO4-P content significantly increased
