Effect of Planting Pattern on Development and Growth of the Branch from each Node on the Main Stem in Soybean Plants.

Effect of Row-Spacing and Planting Density on Podding and Yield Performance of Early Soybean Cultivar ‘Enrei’ with Reference to Raceme Order

“…The square-or triangular-shape planting increased the space occupied by plants than rectangular-shape planting, and promoted the development of branches, thus increasing the seed yield (Cooper 1977, Costa et al 1980, Duncan 1986, Miura and Gemma 1986, Miura et al 1987, Board et al 1990b, Ikeda 2000. Nakano et al (2001) also reported that planting pattern affected the light environment within the canopy, which determined the branch node number, pod number and seed yield. In the present study, the seed yield was in the order of narrow/dense > narrow/sparse > wide/dense > wide/sparse (Table 2, Fig.…”

A high seed yield and associated attributes of dry matter production achieved by recent Japanese soybean cultivars

“…This idea was supported by an examination of the effects of the distance between rows at a constant planting density (15 plants m −2 ); Andrade et al (2002) showed that seed yield at higher light intensity (about 90%) at R1 in narrowly spaced rows (.19 m) was about 10% greater than that at lower light intensity (about 73%) at R1 in widely spaced rows (.57 m). Equidistant plant spacing in narrow-row planting is beneficial because it minimizes competition between plants and increases light interception starting from the early growth stages (Ball et al, 2000;Egli, 1994;Nakano et al, 2001;Weber et al, 1966). Recently, narrow-row planting has been increasing in popularity in Japan due to the potential to improve yield and decrease labor (Furuhata et al, 2008;Uchikawa et al, 2009).…”

Evaluation of the influence of plant population on yield and agro-morphological traits in soybean cultivars (Glycine max L. Merrill)

“…Norsworthy and Shipe (2005) stated that the number of pods per plant and the number of seeds per plant compensated for low plant densities. Nakano et al,(2001) also reported that planting pattern affected the light environment within the canopy, which determined the branch node number, pod number and seed yield. Jason and Emerson (2005) reported that low plant densities in soybean may result in an increase in the number of lateral branches and in a greater contribution of these lateral branches to the total yield.according toWells et al, (1993) radiation penetrating in to canopy was decreased with high plant density and reduced branches number.…”
