Soybean (Glycine max (L.) Merr.) is the most important legume for food production. Soybeans, in Serbia, in the last years, are grown on 180,000 ha to 200,000 ha. Several-year-old soybean yields were about 2.5 kg ha-1, in average. The year 2016 had the record yield of 3.5 kg ha-1. Growth of soybean production was registered in Serbia, primarily due to increase of its production area and also because of its yield increase. High yields will be reduced when deficit in essential nutrients and precipitation are present. The aim of this investigation was to estimate the effect of seed inoculation and fertilization on plant height in soybean variety, in arid year. In dry years, fertilization has a significant effect on increasing the soybean yield and mitigate the effects of drought. In tested year, for the production of soybean, it is recommended the use of 150 kg ha-1 of CAN, directly with the sowing, if it is not applied microbiological fertilizer - NS Nitragin, or use of 100 kg ha-1 of CAN, if it is inoculated with NS Nitragin before seeding.
