Dry Bean Seeding Rate Project Results

With the support of six Ontario dry bean producers located in Huron, Perth and Oxford Counties, a large seeding rate trial was conducted over 3 years on approximately 900 acres of cranberry beans, 600 acres of white beans and 200 acres of black beans. The objectives of the project were to: Demonstrate the use of…Continue readingDry Bean Seeding Rate Project Results

Dry Bean Seeding Rate Project Results (VIDEO PRESENTATION)

A dry bean seeding rate project was conducted from 2018-2020 in Ontario farm fields. White, black and cranberry beans were seeded in large plots in a wide range of seeding rates to evaluate aspects of variable rate seeding and to validate recommended seeding rates.  Below is a 30 minute video summarizing the results. Further reports…Continue readingDry Bean Seeding Rate Project Results (VIDEO PRESENTATION)

Row Width

Row widths of 70–75 cm (28–30 in.) are standard for both white and large-seeded coloured beans when the crop will be pulled and windrowed. In fields with a high risk of white mould, wide row widths are preferred to allow more air circulation in the canopy. Narrow row widths of 36–56 cm (14–22 in.) are…Continue readingRow Width

Seeding Rate

Dry edible bean seed size varies greatly. Check to ensure the planter is calibrated properly to plant the correct number of seeds per meter of row. Adjust seeding rates for seed quality and expected germination rate, field conditions and field history. In conditions where reduced emergence is a risk, increase seeding rates by up to…Continue readingSeeding Rate

Seeding Depth

A seeding depth of 4–6 cm (1.5–2.5 in.) is normal, but deeper plantings of up to 9 cm (3.5 in.) may be necessary to seed into moisture. At minimum, planting depth should be at least 1.2 cm (0.5 in.) into soil moisture. The seeding depth for dry edible beans is critical for uniform emergence. Frequently,…Continue readingSeeding Depth

Planting Date

Generally speaking, early June is the best time to plant dry beans. Planting should occur after the risk of spring frost has past and when there is not a risk of heavy rain after planting. The ideal germination temperature for dry edible beans is 15°C or above. The table below displays the ideal planting dates…Continue readingPlanting Date

Seed Quality

Using high-quality, pedigreed seed from inspected fields is important to promote early season vigour and reduce the risk of seed-borne disease. Bacterial blights, anthracnose and BCMV are seed-borne diseases that cause serious issues in some years. Most coloured bean seed (except black bean seed) is imported from arid growing regions in the U.S. where there…Continue readingSeed Quality

Inoculation

The species of rhizobia for dry edible beans is Rhizobium leguminosarum biovar phaseoli. Dry edible beans are less efficient at fixing nitrogen through rhizobia than soybeans or other legumes. Inoculation trials and routine use of an inoculant have not shown an economic advantage in Ontario, even though other regions do suggest inoculant use for virgin…Continue readingInoculation

Stand Assessments and Replant Decisions

An adequate stand of dry edible beans is a minimum of two-thirds to three- quarters of a full stand. Dry edible beans have a limited ability to branch and compensate Continue readingStand Assessments and Replant Decisions
