Population study on dry beans
Print
EmailWhat was the effect of planting population on dry bean yield at this location this year?
A population study on dry beans was established in Huron County in 2019. Planted populations ranged from 95,000 seeds per acre to 135,000 seeds per acre, in increments of 10,000 seeds per acre. See background information on the plot below.

Row spacing: 20 inches
Variety: Black Bear black beans
Planting date: June 12
Harvest date: Oct. 10
Plot type: Strips, 260 feet by 30 feet, replicated four times.
Effect of Population on Dry Bean Yield 2019
| Planted Population | Actual Population | Yield (lbs. / A) | Sig |
|---|---|---|---|
| 95, 000 | 90,970 | 2380 | a |
| 105, 000 | 102,512 | 2273 | a |
| 115,000 | 111,327 | 2373 | a |
| 125,000 | 119,945 | 2310 | a |
| 135,000 | 128,833 | 2745 | a |
| LSD 0.05 (lbs/A) | 587 | ||
| CV (%) | 10.8 |
Yields of all five planting rates were statistically similar. These results differ from last year, where all planted populations 95,000 – 125,000 yielded statistically similarly, and the 135,000 planted population yielded significantly lower than the 95,000 and the 125,000 planted populations.
