Black and Navy Bean Response to Row Spacing and Plant Population in Eastern ND (05/16/19)

NDSU conducted field research trials from 2014 to 2018 in eastern North Dakota (Carrington, Prosper and Park River) to evaluate potential yield increase of black and navy bean with greater plant populations and narrower rows compared to the traditionally recommended plant density (90,000 plants per acre) in wide rows.

NDSU conducted field research trials from 2014 to 2018 in eastern North Dakota (Carrington, Prosper and Park River) to evaluate potential yield increase of black and navy bean with greater plant populations and narrower rows compared to the traditionally recommended plant density (90,000 plants per acre) in wide rows.

The following is a general summary of the research results:

*Black bean seed yield was similar among the three row spacings (14-, 21- and 28-inches). The greater plant population (slightly more than 140,000 plants per acre) increased yield only 3% compared to the low population (slightly less than 100,000 plants per acre).

*Narrow (14-inch) rows with navy bean plant populations of greater than 115,000 plants per acre increased yield 24% to 28% compared to wide rows with slightly more than 90,000 plants per acre.

The NDSU Extension publication “Black and navy bean response to row spacing and plant population in Eastern North Dakota” provides details of the research and is available online.
