Potassium Partitioning in Response to Genotype and Potassium Fertilization

Whole plant samples from three contrasting cultivars and four potash fertilization levels were sampled at pinhead square, first flower, three weeks after first flower, and six weeks after first flower and divided into stems and branches, reproductive units, leaves, and petioles. These plant components were then dried, weighed, and analyzed for potassium concentration. Using this data, potassium partitioning changes in response to both cultivar and fertility were assessed through the growing season.
