Organic and conventional method of coffee farming on microbial diversity indices.

Systems	Soil depth (cm)	Microbial diversity indices
		Shannon-Weiner Index ()	Simpson’s Index of Diversity ()	Simpson’s Reciprocal Index (1/)	Shannon Evenness ()	Simpson’s Evenness ()
Organic	0–15	2.68	0.40	2.52	0.90	0.55
Conventional	0–15	2.56	0.44	2.28	0.85	0.51
	CD (0.05)	0.035	NS	0.02	0.024	NS
Organic	0–30	2.54	0.42	2.32	0.84	0.51
Conventional	0–30	2.55	0.43	2.27	0.85	0.51
	CD (0.05)	NS	NS	NS	NS	NS

All the values are mean of 5 replications; CD: critical difference; NS: nonsignificant.
Superscript letters indicate statistical significance following Tukey multiple comparison tests.
