Response of Soybean (Glycine max (L.) Merrill) to Mineral Nitrogen Fertilization and Bradyrhizobium japonicum Seed Inoculation

摘要: A growing interest in soybean cultivation Poland has been observed the recent years, however it faces a lot of difficulties resulting from poorly understood effectiveness plant nitrogen fertilization and introduction Bradyrhizobium japonicum to environment. The aim study was evaluate consistency response two cultivars three different rates mineral N seed inoculation treatments with B. field conditions over four years regardless previous presence soil. highly-diversified-over-years rainfall temperature season do not allow for definite statement differences applied separately or jointly soybean. high sensitivity nodulation process deficits noted, which resulted decreased amount DNA measured qPCR dry matter nodules. ‘Annushka’ demonstrated higher yield seeds protein, plants 1st pod setting. ‘Aldana’, due significant decrease density, produced number pods, per 1000 weight plant. Both responded an increase after HiStick, also application 30 60 kg N, as well Nitragina N.
