e0“The investigations revealed highly significant correlations between disease severity (diseased leaf area) and yield components (pod number per plant, total grain number per plant, total grain weight per plant, percent of ripened grain, weight of hundred seed, and yield)”
e1“The correlation coefficients between leaf spot severity and each component were -0.90, -0.90, -0.92, -0.99, -0.90 and -0.94, respectively”
e2“This study was carried out to investigate yield loss due to soybean leaf spot disease caused by Cercospora sojina Hara”

Other claims from this paper (9)
- Association Leaf spot severity was negatively correlated with pod number per plant (r = -0.90).
- Association Leaf spot severity was negatively correlated with total grain number per plant (r = -0.90).
- Association Leaf spot severity was negatively correlated with percent of ripened grain (r = -0.99).
- Association Leaf spot severity was negatively correlated with weight of hundred seed (r = -0.90).
- Association Leaf spot severity was negatively correlated with yield (r = -0.94).
- Association The yield prediction model between disease severity and yield gave R2 = 0.9047 with slope -3.7213.
- Association Yield was inversely proportional to the diseased leaf area of soybean.
- Recommendation The economic injury level for soybean leaf spot is 3.3% of diseased leaf area.
- Recommendation The economic threshold level for soybean leaf spot is 2.6% of diseased leaf area.
