Effects of polyaspartic acid urea on rice yield and nitrogen concentrations in paddy field ponding water
To investigate the effects of polyaspartic acid salt(PASP)urea on rice yield and nitrogen(N)concentrations in the ponding water of paddy fields, a field experiment was conducted. We determined the effects of PASP-Ca urea on rice growth, N-uptake and utilization, and N concentrations in paddy field p...
