Abstract
This experiment was conducted in an acid soil low in available K. The treatments were dolomitic lime rates as the main plots and potassium rates as subplots. The soybean seeds of the cv. IAC-14, were inoculated with Bradyrhizobium japonicum. The results demonstrated that liming increased protein content of the seeds, concentration of N in the leaves and seed weight. However, it reduced the hard seed percentage and seed vigor. The supply of K increased oil content, seed weight, concentration of K in the leaves and diminished protein content and hard seed percentage. Possibly, K fertilization and primarily liming may have increased symbiotic activity in the “rooting zone”, and in this way helped to increase the supply of nutrients such as N to the plants, consequently altered the physiological and nutritional quality of the soybean seeds.
