“…It is mostly grown under flooded conditions and consumes up to 43% of the world's developed irrigation resources (Bouman et al, 2007). About 22 million hectares of irrigated dry season rice experience "economic water scarcity" in South and Southeast Asia (Tuong and Bouman, 2002).…”

“…Despite the general water scarcity in this area, high rainfall and severe water-logging often occurs in mid-summer, which causes damage to upland crops and reduces yield and yield stability (Wang et al 2002). Aerobic rice, which is adapted to aerobic non-flooding soils like wheat and maize but still tolerates flooding, is ideally suited for such dual floodprone and drought-prone areas (Bouman et al 2006;Yang et al 2005). Therefore, the interest in 'aerobic rice'-'winter wheat' systems is increasing in the Huai River Basin (Bouman et al 2007a;Feng et al 2007).…”

“…Some recent research focused on water use and yield potential of aerobic rice (Bouman et al , 2006Yang et al 2005), but its response to fertilizers and nutrient-use efficiency have rarely been documented. The shift from flooded to aerobic soil conditions causes changes in soil water status, soil aeration and nutrient availability (Timsina and Connor 2001).…”

In the aerobic rice system, adapted rice cultivars are grown in non-flooded moist soil. Aerobic rice may be suitable for double cropping with winter wheat in the Huai River Basin, northern China plain. Field experiments in 2005 and 2006 were conducted to study the response of aerobic rice and winter wheat to sequential rates of nitrogen (N), phosphorus (P) and potassium (K) in aerobic ricewinter wheat (AR-WW) and winter wheat-aerobic rice (WW-AR) cropping sequences. Fertilizer treatments consisted of a complete NPK dose, a PK dose (N omission), a NK dose (P omission), a NP dose (K omission), and a control with no fertilizer input. Grain yields of crops with a complete NPK dose ranged from 3.7 to 3.8 t ha -1 and from 6.6 to 7.1 for aerobic rice' and 'winter wheat', respectively. N omissions caused yield reductions ranging from 0.5 to 0.8 t ha -1 and from 1.6 to 4.3 t ha -1 for rice and wheat, respectively. A single omission of P or K did not reduce rice and wheat yields, but a cumulative omission of P or K in a double cropping system significantly reduced wheat yields by 1.2-1.6 t ha -1 . N, P and K uptake of both crops were significantly influenced by fertilizer applications and indigenous soil nutrient supply. Nutrient omissions in a preceding crop reduced plant N and K contents and uptake additionally to direct effects of the fertilizer treatments in wheat, but not in rice. Apparent nutrient recoveries (ANR) differed strongly between 'aerobic rice' and 'winter wheat'; in rice: for N it ranged from 0.30 to 0.32, for P from 0.01 to 0.06, and for K from 0.03 to 0.19 and in wheat: for N from 0.49 to 0.71, for P from 0.09 to 0.15, and for K from 0.26 to 0.31. Further improvements of crop productivity as well as nutrient-use efficiencies, should be brought about by developing cropping systems, by an appropriate choice of adapted cultivars, by a site-and timespecific fertilizer management and by eliminating other yield-limiting factors. It is concluded that nutrient recommendations should not be based on the yield response of single crops only, but also on the after-effects on nutrient availability for succeeding crops. A whole cropping system approach is needed.

“…One possible candidate is reduced sensitivity of grain filling to mild water stress during the grain development phase. Bouman et al (2006) suggested that the relatively high yields of aerobic rice cultivars developed in China may be attributed to their capacity to maintain a high HI through high spikelet fertility under aerobic conditions. In IRRI's aerobic ricebreeding programme, crosses are being made between lowland semi-dwarf indica and upland tall varieties for achieving aerobic adaptation (Atlin et al 2006).…”

Abstract. Increasing yield potential of lowland rice remains to be the top priority in rice geneticimprovement programmes, because rice farmers' primary concern is still grain yield and world rice production has to increase by 1% annually in the next 20 years to meet the demand of the growing population. Improvements in yield potential of irrigated lowland rice were achieved under ample supply of water and nutrients. Water use efficiency (WUE) and nitrogen use efficiency (NUE) were seldom included in the breeding objectives for irrigated lowland rice. Scarcity of freshwater resources has threatened the production of the flood-irrigated rice crop, and excessive use of N fertilizer is causing environmental concerns. We have to increase lowland rice yield with less water and N. Newly developed crop management strategies have proven to be effective in increasing WUE and NUE. Several watersaving technologies such as alternate wetting and drying (AWD) and aerobic rice system have been developed to increase the water productivity of rice. However, yield penalty occurred when these watersaving technologies were practised with current varieties. New varieties have to be developed to reduce the yield loss under AWD and aerobic rice system in order to increase WUE further. Direct selection for WUE under flood-irrigated lowland conditions may have a negative impact on grain yield under watersaving strategies. Optimizing the timing and rate of N application to synchronize supply and demand of N by the crop has resulted in a great reduction in fertilizer-N input without yield loss and greater NUE. Genetic improvement of NUE has not been achieved in rice. Genotypic variation in NUE has been reported in many studies. Plant traits that are associated with high grain yield and high NUE should be identified so that breeders are able to use these traits easily as selection criteria in the breeding programme to develop N-efficient varieties without sacrificing rice yield potential. New breeding techniques such as development of F 1 hybrids, marker-aided selection, transformation and genetic engineering should be combined effectively with the empirical breeding method in order to increase rice grain yield with less water and N.
