Table 5 The effects of CR and ORF cultivation patterns on the micronutrient availabilities in the soil (extracted with 1āM ammonium acetate), concentrations in the shoot and seed at 2013 and 2014. In the table, calculated by ANOVA with Tukey test (pā<ā0.05), differences between treatments were significantly representing by bold-filled column on the mean ranks with letters (a-b). CR: conventional rice planting system; ORF: organic rice-frog coculture system.
