  1. CK was negative control; F was bio-fertilizer treatment; R was rotten straw treatment; RF was bio-fertilizer + rotten straw treatment. Values were represented as means ± SEs, and the different small letters within each column of cultivar (C), amendment (M) and C*M means significantly differences at 0.05 level based on ANOVA test.
