“…The treatment N 5 received highest dose of N (225 kg ha -1 ) and able to facilitate high vegetative growth rather than reproductive output. Sui et al, (2013) and Ghosh et al, (2017) noticed that biomass production under high N fertilized fields was faster and higher than that of optimized N treatments at vegetative stages but not at the reproductive stages.…”

“…Compared to the traditional cropping mode, our results demonstrated that the reduction in panicle number with 25% less basal N application might be compensated by 25% higher planting density. The later top-dressing N application amounts were the same with the CK mode, which might be enough for the rice plant demand during the later growing stages (Kamiji et al, 2011;Sui et al, 2013). Further decrease in basal N application might have significantly inhibited rice tillering (Zhong et al, 2003), which couldn't be compensated by the increase in planting density.…”

“…Evidences showed that panicle number is the key factor determining rice yield (Ottis and Talbert, 2005;Lee et al, 2010), suggesting an increase in panicle can increase rice yield (Zeng et al, 2012;Sui et al, 2013). Some experiments also demonstrated that increasing planting density to some extent could increase panicle number without adverse impact on other yield components (Latif et al, 2005;Hayashi et al, 2006;Lin et al, 2009).…”

“…Thus, dense planting can be good approach to get further increases in rice yield Zhao et al, 2013;Huang et al, 2013), especially for the mechanical rice transplanting, which will be dominant in rice cropping areas (CMA, 2011). Meanwhile, many improved N managements have been made to increase NUE for rice cropping systems (Dobermann et al, 2002;Peng et al, 2010;Rehman et al, 2013;Sui et al, 2013). For example, Peng et al (2006) found that 30% reduction in N application during the early vegetative stage could double agronomic NUE without obvious reduction in rice yield compared to the farmers' practice in China.…”

Rice cropping innovations for high yield with high N use efficiency (NUE) and low greenhouse gas (GHG) emissions are significant in ensuring food security and coping with climate change. The objective of this study was to investigate the comprehensive effects of dense planting with less basal N application (DR) on rice yield, NUE and GHG emissions. Field experiments were conducted at three sites in China: Shenyang, Danyang and Jinxian representing annual single rice cropping system, wheat-rice cropping system and double rice cropping system, respectively. Four planting densities with 25, 50, 75 and 100% higher each time correspondingly with about 25, 50, 75 and 100% less in basal N rate (i.e., DR1, DR2, DR3 and DR4 correspondingly) relative to traditional cropping for high yield (CK). Across three tested sites, the DR1 mode showed a large potential of NUE enhancement by 19.6% and GHG emissions mitigation by 12.2% at area-and yield-scaled with similar rice yield compared to the CK. However, further increase in planting density and decrease in basal N application caused a significant reduction in rice yield with a large increase in GHG emissions. Our results will provide important reference to rice cropping innovations for the integrated goals of food security, environmental health and climate change mitigation in China.

“…Improving NUE together with reducing the application of N fertilizers is an important consideration for the protection of the environment and sustainable production of rice [33]. Many optimized nutrient management strategies have been applied to improve rice yield and NUE in China, most of which have achieved a higher yield and NUE than the usual fertilizer practices by farmers [34]. Rice planting regions and N rates have a significant influence on grain yield, N uptake, and NUE values.…”

Abstract:The objectives of this study were to evaluate the effects of different fertilizer types and application rates on ammonia volatilization loss and to explore nitrogen distribution and nitrogen use efficiency using the 15 N isotope tracing technique in different alkaline salt-affected conditions in the Songnen Plain, Northeast China. The results showed a decreasing trend in ammonia volatilization loss from ammonium nitrate and ammonium sulfate, but not that from urea, as the electrical conductivity gradient increased, whereas the reverse trend was found as the pH gradient increased. Ammonia volatilization loss increased in moderately salt-affected soil compared with that in slightly salt-affected soil, particularly during the tillering stage, regardless of the N fertilizer rate. The percentage of N absorbed by rice plants increased from urea but decreased from the soil as the amount of nitrogen was increased. Interestingly, the N retention rate in soil decreased and rice grain yield and nitrogen agronomic efficiency increased as the amount of nitrogen increased in both salt-affected soil conditions. The nitrogen application amount of highest N physiological efficiency was 225 kg·N/ha. Considering high rice production and a minimal environmental threat, we should fully consider controlling ammonia volatilization losses by adjusting the fertilizer type and the crop stage when the fertilizer is applied.
