Compared to drought-susceptible rice cultivars (DSRs), drought-resistance (DRRs) could drastically reduce the amount of irrigation water input and simultaneously result in higher grain yield under water-saving conditions. However, mechanisms underlying these properties are unclear. We investigated how improved agronomic traits contribute use efficiency (WUE) DRRs than DSRs alternate wetting drying (AWD). Two two were field-grown 2015 2016 using different regimes: continuous flooding (CF)...
Deep placement of controlled-release fertilizer increases nitrogen (N) use efficiency in rice planting but is expensive. Few studies on direct-seeded have examined the effects deep conventional fertilizer. With prilled urea serving as N fertilizer, a two-year field experiment with two rates (120 and 195 kg/hm2) four basal application treatments (B50, all was broadcast 50% N; D50, D70 D100 corresponded to 50%, 70% 100% deeply placed N, respectively) were conducted 2013 2014. Soil distribution...
