Abstract: | 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. |
