Pearson correlation coefficient comparisons for nodule number, nodule dry weight, shoot dry weight, shoot length, and symbiotic effectiveness.

	Correlations
	NN	NDW	SDW	SL	SE
NN	1	0.798	0.790	0.747	0.692
NDW	0.798	1	0.653	0.637	0.493
SDW	0.790	0.653	1	0.839	0.787
SL	0.747	0.637	0.839	1	0.700
SE	0.692	0.493	0.787	0.700	1

Correlation is significant and indicates correlation strongly significant at the 0.01 level (2-tailed). NN = Nodule Number, NDW  =  Nodule Dry Weight, SDW = Shoot Dry Weight, SL= Shoot Length, SE = Symbiotic Effectiveness.
