Impact of Planting Dates on Dry Edible Bean (05/12/16)

Six planting date trials were conducted by NDSU during 2012-15 to explore if dry edible bean seed yield and quality can be increased with early planting compared to the normal planting period (last 10 days of May through first 10 days of June).

Impact of Planting Dates on Dry Edible Bean

Six planting date trials were conducted by NDSU during 2012-15 to explore if dry edible bean seed yield and quality can be increased with early planting compared to the normal planting period (last 10 days of May through first 10 days of June).  Table 1 lists yield across market types with planting dates by year and location. hans.table.1

 Table 2 displays yield by planting dates averaged for each market type.

Summary

The research indicates the planting period of late May through early June normally used by farmers remains appropriate. 

  • Seed yield: The early planting period shows potential for increasing yield but with increased risks. However, yield with early planting was statistically similar to the normal planting period, including during ‘early’ planting seasons (e.g. 2012 and 2015).
  • Seed quality: Test weight tended to increase with normal versus early planting periods, with generally no consistent impact on seed size or appearance (data not presented).
