Abstract Readily available chemical fertilizers have resulted in a decline in the
use of organic manure (e.g., green manures), a traditionally sustainable source
of nutrients. Based on this, we applied urea at the rate of 270 kg ha−1 with and
without green manure in order to assess nitrogen (N) productivity in a double rice
cropping system in 2017. In particular, treatment combinations were as follows:
winter fallow rice-rice (WF-R-R), milk vetch rice-rice (MV-R-R), oil-seed rape
rice-rice (R-R-R) and potato crop rice-rice (P-R-R). Results revealed that green
manure significantly (p ≤ 0.05) improved the soil chemical properties and net soil
organic carbon… More >
