Abstract

The field experiment was conducted at a farm in Wadi Elrabie area (Tajura), which located at the east of Tripoli, Libya, during 2017 and 2018 seasons (loam sandy soil,  pH 8), to study the effect of interaction between organic (Dung) and bio fertilizers (Burkholderia sp), that isolated from Libyan soil (Wadi Elrabie soil) on soft wheat (Triticum aestivum L.) (Balady var.) productivity. Burkholderia brasilensis species belonging to the genus Burkholderia have the ability to improve crop production and fix nitrogen. The results showed that the highest percentage of productivity was achieved when the plants inoculated with bacteria Burkholderia and organic fertilizer treatments. In terms of plant dry weight, weight of 1000 grains and percentage of N and protein in grains, the results showed significant differences comparing to the control treatment. Thus, it can be concluded that the use of a bacterial inoculation with organic fertilizer is effective on wheat productivity.

Key words: Organic fertilizer, Biofertilizer, Wheat.
