Abstract
Abstract In soybean [Glycine max L. (Merr.)] field trials during 1982 and 1983, the effects of seed inoculation with appropriate rhizobia and different levels of NPK fertilizers on yield and yield quality were assessed at two soil salinity levels (EC = 2.9 and 6.8 mmhos cm‐1). For both soils, seed inoculation with rhizobia markedly increased nodule development (number and weight), growth and grain yield, and oil and protein contents of seed. Growth and grain yield were lower in saline than in non‐saline soil. The highest yields of grain from the two soils (5290 and 4720 kg grain ha‐1) were achieved with 213 kg N + 24 kg P + 48 kg K ha‐1. Equal seed yields were obtained by dressing with 142 kg N ha‐1 or by inoculating seeds with Bradyrhizobium japonicum. Inoculation increased oil and protein contents of seed, and in some cases surpassed the oil and protein content obtained with the highest N fertilization rate (213 kg N ha‐1). Substantial increases in soybean growth, yield quantity, and seed quality were achieved either by adding P and/or K fertilizers. Response to P and K fertilizers was more pronounced in the salt affected soil. Key words: dinitrogen fixationNPK fertilization Glycine max soybean oilproteinrhizobiasalinity.
