Abstract Future rice systems must produce more grain while minimizing the negative environmental impacts. A key question is how to orient agricultural research & development (R&D) programs at national global scales maximize return on investment. Here we assess yield gap and resource-use efficiency (including water, pesticides, nitrogen, labor, energy, associated warming potential) across 32 cropping covering half of harvested area. We show that achieving high yields efficiencies are...
Abstract Southeast Asia is a major rice-producing region with high level of internal consumption and accounting for 40% global rice exports. Limited land resources, climate change yield stagnation during recent years have once again raised concerns about the capacity to remain as large net exporter. Here we use modelling approach map gaps assess production potential exports by 2040. We find that average gap represents 48% estimate region, but there are substantial differences among...
Abstract Africa produces around 60% of the rice continent consumes, relying heavily on imports to fulfill rest domestic demand. Over past 10 years, rice-agricultural area increased nearly 40%, while average yield remained stagnant. Here we used a process-based crop simulation modelling approach combined with local weather, soil, and management datasets evaluate potential increase production existing cropland in assess expansion by year 2050 for different scenarios intensification. We find...
Identifying cropping systems with small global warming potential (GWP) per unit of productivity is important to ensure food security while minimizing environmental footprint. During recent decades, double-season rice (DR) in central China have progressively shifted into single-crop, middle-season (MR) due high costs and labor requirements rice. Ratoon (RR) has been proposed as an alternative system that reconciliates both annual relatively low requirements. Here we used on-farm data...
Selecting rice varieties with a high nitrogen (N) use efficiency (NUE) is the best approach to reduce N fertilizer application in production and one of objectives Green Super Rice (GSR) Project China. However, performance elite candidate GSR under low supply remains unclear. In present study, differences grain yield NUE thirteen fourteen two controls were determined at rate 100 kg ha-1 field experiments 2014 2015, respectively. The for all ranged from 8.67 11.09 t ha-1, except japonica...
Yield loss (YLoss) in the ratoon crop due to crushing damage left stubble from mechanical harvesting of main is a constraint for wide adoption mechanized rice ratooning technology. Soil drying before harvest has been proposed overcome this problem. The objective study was determine effect soil during mid-to-late grain filling stage on yield system. Field experiments were conducted compare YLoss between light (LD) and heavy (HD) treatments Hubei province, central China 2017 2018. calculated...
Abstract Hybrid rice has been planted throughout China to ensure food security owing its higher yield potential than inbred rice. Meanwhile, substantial nitrogen (N) fertilizer applied feed hybrid varieties for maximizing grain yield. However, what extent the of depends on N input remains unclear. A meta‐analysis was conducted in this study (1) quantify difference uptake and utilization between rice; (2) determine whether requires more producing per unit yield; (3) evaluate impact crop...
Labor scarcity requires double-season rice to be planted by direct seeding as an alternative transplanting. Only ultrashort-duration varieties can used in direct-seeded, (DSD) central China where thermal time is limited. Whether grown DSD productive and efficient nitrogen (N) use transplanted (TPD) remains unclear. Field experiments were conducted Hubei province, with two establishment methods (DSD, TPD) three N rates the early late seasons of 2017 2018. Nitrogen treatments included zero-N...

Crop production is threatened by the increased nitrogen (N) input and declining N use efficiency (NUE). Information on total from planted seeds/tubers, atmospheric deposition, irrigation water, crop residues, animal manure, biological fixation, synthetic fertilizer NUE based these inputs in China’s limited. We calculated amount of various 117 primary crops 1961 to 2012 China. The 8.0 Mt 60.8 2012. substantial shift types was observed manure fixation toward fertilizer. Animal plus accounted...
Rice yield potential was greatly improved since the green revolution, but occurrence of lodging often restricts achievement yield. Currently, it is still obscure about how lodging-related traits change along with genetic improvement in rice, although much efforts have been devoted to study trend and physiological mechanisms underlying changes grain Therefore, fourteen rice mega-varieties that were released disseminated from 1930s 2005 China investigated through a two-year experiment field...
Increasing rice yield and its stability are important to achieving the sustainability of production. Rice yields have increased substantially in China during recent decades, but information on trend has been limited. In this study, trends from 1949 2015 were analysed China's production.The results showed that for all 16 provinces presented an increasing study period. The national annual gain was 86.0 kg ha-1 last six varying 48.4 106.0 different exhibiting linear, bilinear, or trilinear...
