- W3183431881 abstract "Abstract Aims: In the absence of tillage, perennial rice is an innovation and supplement to rice production. Evaluating crop N uptake and N requirements and maintaining soil N balance are essential for informing decisions regarding optimal N management and the accessibility of the soil environment benefits of perennial rice cropping systems. Methods: To assess the soil nitrogen cycle and balance, formulate optimal N fertilizer management for perennial rice, a field experiment with four nitrogen rates (N0, N1, N2 and N3 refer to 0, 120, 180 and 240 kg N ha -1 , respectively) integrated with three planting densities (D1, D2 and D3 refer to 100×10 3 , 167×10 3 and 226×10 3 plants ha -1 , respectively) was conducted for two years over four seasons (2016-2017) in southern China. Results: The results showed that N2D3 mode could sustainably produce higher dry matter accumulation (15.15 t ha -1 ) and grain yields (7.67 t ha -1 ) over four seasons, showed significantly higher N uptake (201 kg ha -1 each season) and less soil N loss (27.1%). Additionally, the N2D3 mode could reach the optimal N balance (-0.2 kg ha -1 ) in perennial rice fields with low N requirements (23.9 kg N Mg -1 grain), resulting in higher N use efficiency (NAE: 26.5 kg N kg -1 , NRE: 64.9%). Conclusion: In the perennial rice cropping system, 180 kg N ha -1 integrated with 226×10 3 plants ha -1 resulted in higher grain yields with lower N requirements, higher N use efficiencies, and lower soil N losses, thereby maintaining the soil N balance for sustainable perennial rice production." @default.
