Yield reductions have been widely observed under water-saving irrigation in lowland rice. The yield gap has been related to decreases in the number of spikelets per panicle and decreased spikelet fertility. Since these yield components highly depend on the thermal environment of the meristem which is subjected to changes when a ponded water layer is omitted, the impact of irrigation system on yield...
Growth and grain yield reductions have been widely observed when traditionally flooded rice fields were subjected to water-saving irrigation measures, where a continuous floodwater layer is avoided. These observations led to the perception of rice being a plant extremely sensitive to water stress even when grown in soils where water is sufficiently available. Since the rice plant's meristem is below...
