Phosphorus-use efficiency of kale genotypes from coastal Croatia
Understanding the mechanisms of P-use efficiency may contribute to enhancing crop P nutrition because species growth variability at low-P is well known. The experiment was carried out to evaluate the response of kale genotypes to different P supply in randomized block design in three replications. Low-P supply led to a decrease in most parameters, whereas an increase was recorded in root growth parameters. Genotypes differed in shoot DW, leaf area, root lenght and area, and shoot and root P content and concentration. Root traits significantly positively correlated with PUE. RR and IJK 17 were superior in terms of shoot DW production at low P supply and had the highest uptake efficiency. IJK 17 and 81 had the highest P utilization efficiency, while VBC showed the lowest PUE. Genotypes had similar shoot P content and concentration at low P supply, but large PUE differences, implying importance of P utilization efficiency.
