Other claims from this paper (13)

Intervention effect Mixed planting clearly reduced lodging of Koshihikari.
Observation About 60% of the reduction in lodging of Koshihikari was contributed by the propping effect of Kanto 100.
Observation About 40% of the reduction in lodging of Koshihikari came from increased lodging resistance of Koshihikari due to mixed planting.
Intervention effect Mixed stand increased the number of photosynthetic leaves and leaf-sheaths of Koshihikari compared with pure stand.
Intervention effect Mixed stand increased the stem diameter and breaking strength of the lower internode of Koshihikari compared with pure stand.
Intervention effect Mixed planting increased rice yield.
Intervention effect Yield of Koshihikari increased in mixtures.
Intervention effect Yield of Kanto 100 tended to decrease in mixtures.
Intervention effect Mixed stand yield was about 6.7% higher than the mean yield of the pure stands of the two cultivars.
Observation Yield increase in Koshihikari was nearly equal to the yield reduction in Kanto 100 under no-lodging conditions.
Intervention effect With lodging prevented by a net, the yield in the whole community did not increase.
Mechanism Yield increase by mixed planting without a net resulted mainly from prevention of lodging of Koshihikari (author interpretation).
Mechanism About 40% of the yield increase in Koshihikari was due to competition compensating for the yield reduction in Kanto 100 (author interpretation).
