For each season, means within a column followed by different lower case letters are significantly different (p ≤ 0.05, Tukey’s Studentized range test).

For each agroecology surveyed more than once means within a column followed by different upper case superscript letters are significantly different across seasons (p ≤ 0.05, Tukey’s Studentized range test).
