“…Reports of row spacing effect on soybean plant height are inconsistent. In many studies, plant height increased as row spacing decreased (Hicks et al, 1969;Beaver and Johnson, 1981;Bharati, 1984). Other studies have indicated that plant height is reduced with a decrease in row spacing (Sesay, 1972;Taylor 1980).…”

“…Several studies have shown a decrease in plant height with a reduction in row spacing (Sesay, 1972;Taylor, 1980). Other reports have shown an increase in plant height when row spacing was reduced (Beaver and Johnson, 1981;Bharati, 1984).…”

“…This research supported the hypothesis that there is a row spacing by water supply interaction. Bharati ( 1984) reported on row spacing and population effects on soybean seed yield in Iowa; averaged over three population levels, soybeans planted in 25-and 51-cm row widths yielded significantly better than those planted in 76-cm rows. His results did not show a statistical difference in yield for 25-and 51-cm rows.…”

“…: The lack of plant lodging also provides evidence that the plant height differences were not significant. Row spacing influence on plant height has been very inconsistent in past research, suggesting that other variables, such as planting date and plant population, are more important in plant height determination (Taylor, 1980;Bharati, 1984).…”

Can Weeds Overtopping Soybean or Adzuki Bean Be Mechanically Pulled to Reduce Their Seed Input?

2019

Tall weeds escaping early weed management, such as weeds resistant to one or multiple herbicides, are an increasing concern. When weeds reach a certain size, few options other than hand weeding will limit the production and dispersal of seeds. The objective of this project was to evaluate the efficacy of the Bourquin Organic Weed Puller® (a rotating series of wheels that grab and pull) at removing tall weeds before they shed seeds in soybean and adzuki bean. Trials were set up in Canada at the Agriculture and Agri-Food Canada research farms at Saint-Jean-sur-Richelieu (SJR), QC (2 yr), and Harrow (HAR), ON (1 yr), on a loamy and a sandy soil, respectively. The experimental design included crops of different potential heights (different soybean cultivars and adzuki bean), two weed species per location (common lambsquarters [both locations] and common ragweed or redroot pigweed at HAR), and two pulling dates. The set-up also included weedy and herbicide-treated control plots. Weeds overtopping the crop canopy by at least 10 cm were tagged and characterized. Damage from the weed puller was rated as 1, pulled (desired effect); 2, cut; 3, folded; 4, stripped; and 5, intact. The seed production of damaged and intact weeds was also recorded. Less than one-third of common ragweed or redroot pigweed plants were pulled during any treatment combination. The highest pulling rates were observed for common lambsquarters at SJR (43%), but very few were pulled at HAR (3.1% max). Pulling rates were not high enough to potentially control seed inputs from herbicide-resistant populations, and successfully pulled common lambsquarters left on the ground produced thousands of viable seeds.
