Screening for Mn efficiency in soil-based pot testing had been producing inconsistent results, and thus improvement of pot screening became an objective. One possible factor, pot size was examined as the cause, using two sizes of pot. In large pots, the expectation of higher dry matter and shoot Mn concentration in a Mn-efficient genotype compared to a Mn-inefficient genotype was realised over a wide range of Mn supply, whereas in small pots, the genotypic differences were expressed at only one, low rate of Mn supply (10 mg kg soil-1). Plants in the small pots strongly responded to root restriction by decreasing yields and increasing root/shoot ratios and Mn concentrations of shoots. The critical value of Mn concentration for shoot growth was not affected by the small pots, but the Mn mobilization by plants might be affected in the small pots. The practical outcome of these results is that using an adequate size of pot and measuring the Mn concentration of shoots, soil-based pot screening for Mn efficiency can be improved.
