Awadalla AO, Mohammed T Abbas

To study the effects of N-fertilization and diazotroph inoculation on yield and its` components of Peanut (Arachis hypogaea L.) cv Giza 5 in new land soil at toshka project south valley region, tow field experiments were carried out in the farm of Toshka Research Station, Agriculture Research Center. During 2015 and 2016 seasons. Results showed that increasing N fertilization levels from 20 to 60 kgN/feddan and use of rhizobia + enterobacter inoculation, significantly increased No. pods/plant, Wt.pods/plant(g), Wt.seeds/plant(g), seed index, Wt.pods/fed.(ton) and Wt.seeds/fed. (ton). Oil and protein % in seeds compared to control treatment. The studied characters of yield and its attributes were significantly affected by the interaction between N fertilizer levels and diazotroph inoculation. Peanut fertilized with 60 kg N/fed. With rhizobium+enterobacter treatment recorded the highest significant values of most studied characters than the other treatments.
