Effect of inoculation, late N‐ and PK‐manuring and irrigation on seed yield and N‐accumulation in the seed of several varieties of soybean at two locations in Germany Effect of inoculation with rhizobium, late N‐ and PK‐fertilization and irrigation on yield and N‐accumulation in seeds of four soybean cultivars was tested in a polyfactoral experiment design. Seed yield ranged from 11.5 to 43.7 dt DM/ha and N‐accumulation in seeds from 52 to 247 kg/ha. Irrigation and inoculation were the most effective production techniques. Cultivar MA96 yielded 38.0 dt DM/ha in Frankenthal on a sandy soil when plants were irrigated and inoculated. No further yield increase was obtained with additional NPK‐fertilization. Cultivar KW269 resulted in a significant higher yield (43.7 dt DM/ha) when late N‐fertilization was given to irrigated and inoculated plants.
