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

Bald Heads

Bald heads refer to seedlings that emerge with damaged or no growing point. Cotyledons (seed leaves) may or may not be present. Plants may develop auxiliary buds at the base of cotyledons but they fail to develop. Without a growing point, plants eventually die. The most common cause of bald heads is mechanical damage to…Continue readingBald Heads

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

Plant Development

Bean varieties are characterized by their growth habit. Indeterminate plants continuously grow and exhibit long vines. Most of the commonly grown bean types have a semi-determinate growth habit, meaning they continue to grow after flowering begins and develop short to long vines. Determinate types tend to flower and ripen over a short period. Determinate types…Continue readingPlant Development

Phosphate and Potash

Phosphate and potash recommendations for dry edible beans are presented below in the tables below. Where soil fertility levels are adequate, dry edible beans show minimal response to starter phosphorous. Where potassium fertility is low, deficiency symptoms appear in white beans as yellowing of the lower leaves and necrosis on leaf margins. Dry edible bean…Continue readingPhosphate and Potash
