Studies on the Effect of Nonuniformity of Planting on Growth and Yield of Crops. : I. Effect of nonuniforrnity of the number of seedling per hill on growth and yield of rice

Effects of Planting Pattern on the Interception of Solar Radiation by the Canopy and the Light Extinction Coefficient of the Canopy in Rice Plants Direct-sown in a Submerged Paddy Field

“…There are some reports on the effects of planting pattern on the number of tillers. At the tillering stage, the number of tillers per square meter increased as the number of plants per hill increased (Tsunoda et al, 1971;Nakano et al, 1994) and in plants grown at a higher hill density (Ehara et al, 1998). However, the number of tillers was larger in the plots with a row arrangement than a square arrangement of hills at a density of 40 to 50 hills per m 2 at the panicle formation stage, although the number was almost the same at heading (Akita and Tanaka, 1992).…”

Ecophysiological Analysis on Effect of Planting Pattern on Biomass Production and Grain Yield in Rice

“…High hill density or a high number of plants per hill are generally advantageous in early growth. At the tillering stage, the number of tillers per square meter increased as the hill density or number of plants per hill increased 6,41,66,70 . Introduction of mechanized transplanter, which was employed rapidly during the 1970's-1980's in transplanting rice cultivation in Japan, enabled higher hill density as compared with manual transplanting, which resulted in increased grain yield 14 .…”
