Phosphorus (P) deficiency is a principal yield-limiting factor for annual crop production in acid soils of temperate as well as tropical regions. The objective of this study was to screen nine corn (Zea mays L.) genotypes at low (0 mg P kg-1), medium (75 mg P kg-1), and high (150 mg P kg-1) levels of P applied in an Oxisol. Plant height, root length, shoot dry weight, root dry weight, shoot-root ratio, P concentration in shoot and root, P uptake in root and shoot, and P-use efficiency parameters were significantly (P<0.01) influenced by P treatments. Significant genotype differences were found in plant height, shoot and root dry weight, P uptake in root and shoot, and P-use efficiency. Based on dry matter production and P‐use efficiency, genotypes were classified as efficient and responsive, efficient and nonresponsive, nonefficient and responsive, and nonefficient and nonresponsive. |
