Soybean Plant Stand Assessor
Using Row Length Method
Number of Plants Per Row
Count the number of plants along the same length of row indicated above in at least 3 areas
Plant Population
High: (>160,000 plants/ac)
Beyond the recommended plant stand, disease pressure may be increased
Good: (140-160,000 plants/ac)
Within the recommended range
Adequate: (120-140,000 plants/ac)
Within 5% of the recommended range
Low: (80-120,000 plants/ac)
Risk of yield loss
Very Low: (60-80,000 plants/ac)
High risk of yield loss, particular attention to weed control and pod height important
Plant population and yield information is based on final research results from Mohr et al. 2014. The effect of actual plant stand on relative yield of soybean was determined based on13 site years of data in Manitoba from 2011-2013.
