“…On the other hand, there are negative aspects in high hill density and high number of plants per hill in later stages, such as the reduction of percentage of productive stems and smaller number of spikelets per panicle 1,6,17,41 . In addition, excessive vegetative growth 1,70 , lowered nitrogen concentration in plants and shallow root systems 62 occurred.…”

Increasing the biomass productivity of rice is a critical research target for improving the yield potential. This paper reviews ecophysiological studies on biomass production as affected by agronomic techniques and cultivars. In addition, we examined the effects of the planting pattern on the biomass production using cv. Takanari, a high-yielding and lodging resistant cultivar. The results showed that greater biomass production and grain yield were observed in plants with the combination of one plant per hill, high hill density and square hill arrangement. The factors responsible for high biomass production in this combination are; (1) vigorous tiller increase at the tillering stage resulting in higher capture of solar radiation, (2) erect leaves in the canopy after the panicle formation stage resulting in an improved light-intercepting character or smaller extinction coefficient, and (3) larger nitrogen accumulation during the ripening period resulting in a smaller decline of photosynthesis as well as a smaller midday and afternoon depression of photosynthesis possibly related to the larger water uptake ability of roots owing to better root-system development. Our results implied that an improvement in biomass production and yield is possible by optimizing the planting pattern and nitrogen management using high-yielding and lodging resistant cultivars in transplanted and direct-sown rice.
