Title

The Effect of Irregular Disposition of Rice Plant on Yield in Direct Sowing Culture

Masami HIMEDA; Seiichi IZUMI Japanese Journal of Crop Science 1965. doi:10.1626/jcs.33.399

Other claims from this paper (9)

Intervention effect More irregular disposition of rice plants caused a greater decrease in grain weight per unit area.
Intervention effect The decrease in grain weight with irregular disposition was more remarkable in Fujiminori than in Manryo.
Mechanism Decrease of grain weight was caused by a decrease in the number of panicles per unit area.
Association In Fujiminori, the number of panicles decreased as irregularity in plant disposition increased.
Intervention effect In Fujiminori, grain weight per panicle remained unchanged as irregularity in plant disposition increased.
Association In Manryo, grain weight per panicle increased.
Association In Manryo, the number of panicles decreased.
Intervention effect In plots of cv 30∼100 %, no decrease of grain weight was observed relative to the plot of cv 0 %.
Intervention effect In Manryo, the difference in the effect of irregular disposition on grain weight between spacing densities was not clear.

Studies of Direct-sowing Rice Culture by Broadcasting of Seed on submerged Paddy Field : IV. Relationship of seeding density to plant growth and rice yield

Seiichi AKAMATSU Japanese Journal of Crop Science 1966. doi:10.1626/jcs.35.131

Other claims from this paper (10)

Intervention effect Dense sowing gave higher rice culm height early than sparse sowing.
Intervention effect The early culm height ranking reversed later.
Intervention effect Dense sowing increased tillers per unit area at peak tillering.
Observation At harvest, 90-hill plots had the greatest panicle number, 502 per square meter.
Observation At harvest, 30-hill plots had the smallest panicle number, 304.
Observation More densely sown plots had about 405 panicles, lower than the 90-hill plot.
Intervention effect Rice yield was highest in the 90-hill plot.
Intervention effect Rice yield above 120 hills was lower than in the 90-hill plot.
Mechanism The authors attributed lower dense-plot yield to inadequate customary fertilizer in later growth.
Recommendation Improved split fertilizer application may make dense-plot rice yield more favorable.
