Correlation coefficients and degree of dependence for yield indicators and general biogenesity of the soil

Traits Correlation coefficient Degree of dependence Regression equation
In rotation with complete fallow
Yield – general biogenesity Plowing r=0.62 medium direct y = 3.96x – 1.39
Loosening r=0.65 strong direct y = 3.34x + 1.34
No autumn mechanical treatment r=0.79 strong direct y = 4.78x – 1.61
In rotation with green‐manured fallow
Plowing r=0.59 medium direct y = 6.28x –5.74
Loosening r=0.79 strong direct y = 6.36x – 6.29
No autumn mechanical treatment r=0.78 strong direct y = 7.78x – 7.49
