Phenological traits of the common bean accessions grown in native and agricultural soils. Data for root dry weight and the number of days to reach the flowering stage is shown

The mean values of four replicates (agricultural) and three replicates (native) per accession are shown, followed by the standard deviation of the mean. The harsh conditions of the native soil prevented us to have four replicates for all the accessions; therefore, it was decided to normalize the number of replicates to three in native soil samples. Statistical analysis of root dry weight and days to flowering were done between bean accessions per soil type. ANOVA and LSD (P < 0.05) tests were applied after checking for assumptions of normality and homoscedasticity. Accessions with the same letter are not significantly different
