Mean and standard error values were calculated for plant growth,
insect performance, and foliar protein and polyphenol oxidase content.
Two factors of this study included PGPM and fertilizer. A two-way
analysis of variance (ANOVA) and Tukey's multiple-range test (Version
6.2; SAS Institute Inc., Cary, NC, USA, 1996) were used for comparing the
interaction effects between fertilization and microbial application.
