A field experiment was.carried out at Is.ailia Res.arch.s.ation, Is.ailia Governorate from 2020-2022 to improve th. growth.of Kh.ya s.negalens.s.and s.ietenia mah.goni by us.ng a combination of mineral fertilizer (NPK) and biological fertilizer (Azotobacter ch.oococcum, Bacillus.megath.rium, and Bacillus.circulant) as.recommended dos. under new s.ndy s.ils.conditions. s.lit plot des.gned with.four treatments.(Control, (50% Mineral fertilizer (M.) + 50% Biological fertilizer (Bio.)), 100% M. and 100% Bio.) of each.s.ecies. Vegetative growth. leaf area, tree biomas., s.ored carbon, bas.l area, tree volume, and in th. s.il both.of microbial account and mineral content were determined. Th. experimental res.lts.s.0}wed no s.gnificant differences.between s.udied s.ecies.among th. mos. s.udied parameters.except for Kh.ya s.negalens.s.wh.ch.gave th. h.gh.s. s.gnificant difference in root biomas. and below-s.ored carbon th.n s.ietenia mah.goni. Evidently, th. h.gh.s. s.gnificant growth.parameters.were 100% mineral fertilizer followed by (50% M. + 50% Bio.) as.compared with.control. No s.gnificant difference between 100% M. and (50% M. + 50% Bio.) of s.0}ot dry biomas. (15.19 and 12.02 kg, res.ectively) and above-s.ored carbon (0.28 and 0.22 Mt, res.ectively). Microbial account and mineral content in s.il were improved after cultivation of tree s.ecies.compared to before planting and control, es.ecially with.50% mineral fertilizer and 50% bio-fertilizer treatment. In conclus.on, a treatment containing 50% mineral fertilizer and 50% bio-fertilizer h.s.led to th. ideal Kh.ya s.negalens.s.and s.ietenia mah.goni growth.in s.ndy s.il for ch.aper and s.s.ainable.
