This experiment was carried out in sandy loam soil of private from at Romana , North Sinai Governorate, Egypt during two successive winter seasons 2017 / 2018 and 2018 /2019, to study the effect of three types of biochar, (A) produced from corn stalk, straw rice , straw of faba bean and cotton stalk, (B) produced from trees stalk and (C) town refuse, with three levels from Urea fertilizer (0, 20, 30 Kg N/fed), plus control treatment which received the recommended dose of urea (46 %N), to examine the effects of biochar types combined with or without nitrogen fertilizer on faba bean productivity under saline soil conditions. Faba bean variety Giza 843 were sowed on 12 November 2017 and 2018The experiment was carried out in a split plot design with three replicates. The used to three biochar types were arranged randomly as sub plot, were different rates of mineral nitrogen fertilizer was distributed randomly as main plot. Results obtained that, the combination between biochar types with different levels of N fertilizer enhanced all tested parameters. Moreover, biochar type (C) with level 30 Kg N/fed recoded the highest values of all tested parameters. On the other hand, the same treatment was the most effective on the root rot and wilt incidences, where the survival plants was % 97.9 and 93.4 respectively and decreased the number of the pathogenic fungi.
