The yield of treatment T1 was set as reference for the t-test. SD is standard deviation. CV is coefficient of variation, i.e. SD divided by mean.

^†Treatments are explained in Table 2.

^‡Significance were displayed with numbers of asterisk, ‘***’ means p value ≤ 0.001, ‘**’ means 0.001 < p value ≤ 0.01, ‘*’ means 0.01 < p value ≤ 0.05 and ‘NS’ means p value > 0.05, i.e., not significant.
