Field studies were conducted to determine the nitrogen (N) fertilizer replacement value (NFRV) when soybean (Glycine max [L.] Merrill) preceded corn (Zea mays L.) in the rotation (S-C), compared to corn preceding corn (C-C). Large, replicated blocks

Soybean [Glycine max (L.) Merr.] production in short-season areas has increased greatly because of improvements in cultivars and production practices. Previous studies of genetic improvement in soybean have reported yield increases of 0.5 to 1% per y

High levels of FFA have been a recurring problem in the seed oil of Ontario-grown, canola-quality summer rape (Brassica napus L.). Examination of seed samples from the Eastern Canadian Co-operative Cultivar Trials conducted at several locations in 19

Field studies were conducted in 1989 and 1990 to determine the FFA levels during seed development of three Ontario-grown canola-quality summer rape (Brassica napus L.) cultivars, Global, Kristina and OAC Triton, to determine the relationship between

Spring canola (Brassica napus) seed grown in Ontario frequently exhibits elevated levels of free fatty acids (FFA) in the oil. The objective of this study was to determine the effects of various agronomic practices on FFA levels. Several field experi

An automated method for measuring free fatty acids (FFA) in canola seed was developed by using gas-liquid chromatography (GLC). The results from the GLC method were linearly related (r2=+0.98) to those obtained with the traditional method involving S

Grain legumes often are credited with leaving residual N for crops that follow in the rotation. This study was conducted to determine if increasing N 2 fixation in soybean [Glycine max (L.) Merr.] would result in higher amounts of stover N at harvest

Strain 532C of Bradyrhizobium japonicum has outperformed other soybean [Glycine max (L.) Merr.] rhizobial strains in Ontario trials conducted with cv. Evans. Strain HH303 of Sinorhizobium fredii has proven effective with some Ontario cultivars. The o

In the absence of Bradyrhizobium japonicum populations in the soil, yields of field-grown soybean (Glycine max (L.) Merrill) usually respond to inoculation with B. japonicum. The objective of this research was to determine the relationship between nu
