a Phenotypes of peanut plants under control conditions and when treated with Pseudomonas sp. 1502IPR-01, unchelated pyoverdine and control group, in intercropping peanut and monocropping peanut in sterilized soil, and monocropping peanut in normal soil in greenhouse conditions (rhizosphere watering application). b Soil Plant Analysis Development (SPAD) values and active iron in young leaves, biomass and available iron in the rhizosphere of peanut under the three treatments (control, 1502IPR-01, unchelated pyoverdine of 1502IPR-01) in greenhouse conditions. c Phenotypes of peanut plants under control conditions and when treated with either Pseudomonas sp. 1502IPR-01 (rhizosphere application), unchelated pyoverdine (rhizosphere application), or EDTA-Fe (foliar spraying) in monocropping peanut in field conditions. d SPAD values in young leaves, active iron concentrations in young leaves, available iron in the rhizosphere and peanut yield under the four treatments (control, 1502IPR-01, unchelated pyoverdine, spraying EDTA-Fe) in field conditions. For b bars and error bars represent the mean ± standard deviation (SD) and dots represent individual values. For d boxplot center lines show the median, boxplot bounds show the first quartile Q1 and the third quartile Q3, and whiskers show 1.5 (Q3-Q1) below and above Q1 and Q3, and black dot represent outliers and open dots represent individual values, respectively. For b and d data obeyed normal distribution and homogeneity of variance, ANOVA with LSD as post-hoc test is used in parametric test. For skewness data or data with heterogeneity of variance, data is transformed using BoxCox algorithm for parametric test. Kruskal test with Dunnett T3 test is used if data did not meet the assumptions of parametric test after BoxCox algorithm. Different letters indicate significant differences among groups. Multiple testing corrections are performed by BH algorithm. Asterisks indicate significant differences between two groups: *p < 0.05; **p < 0.01; ***p < 0.001, n.s not significant. For all parameters, n represents the number of biologically independent samples. Two-sided tests were used for alternative hypothesis testing. Source data are provided.
