Soybean-corn succession according to seeding date

Using near infrared spectroscopy to classify soybean oil according to expiration date.

A rapid and non-destructive methodology is proposed for the screening of edible vegetable oils according to conservation state expiration date employing near infrared (NIR) spectroscopy and chemometric tools. A total of fifty samples of soybean vegetable oil, of different brands andlots, were used in this study; these included thirty expired and twenty non-expired samples. The oil oxidation was...

Influence of Soybean Planting Date and Leaf Age on Resistance to Corn Earworm (Lepidoptera: Noctuidae)

Environ.Entomol.21(2):264-268(1992) ABSTRACT Soybean, Glycine max (L.) Merr., resistance to insects has been shown to vary with planting date and leaf age. This study determined effects soybean genotype, planting date, and leaf age had on feeding behavior of com earworm, Helicoverpa zea (Boddie). Soybean genotypes 'Cobb' (susceptible) and 'GatIR81-296' (resistant) were planted early (29May) and...

Seeding Date and Performance of Specialty Oilseeds in North Dakota

Interest in oilseeds and oilseed crop production has recently been heightened by the growing potential for biofuels. Traditional oil seed crops, such as sunflower (Helianthus annuus L., Asteraceae), flax (Linum usitatissimum L., Linaceae), and more recently canola (Brassica napus L., Brassicaceae) have become crops of major importance in the region. The key to their production success is multi-...
