| Abstract | ||
| Field experiment was conducted at one of the private agricultural field private of Al-Jazira – Al-Boasaaf area, west of Ramadi, in loamy soil texture to investigate the role of A. chrococcum and G.mossae biofertilizer, as single addition or in combination with NPK (chemical fertilizers) to increase the availability of concentrations of nutrients in the soil and the absorbed amount in potato tuber CV. Burren. The result showed that the bio-fertilizer A. chrococcum, G.mossae and NPK as individual addition led to a significant increases of the nutrients average concentrations in both soil and plant. The three factor interaction between A. chrococcum,G.mossae, A. chrococcum and chemical fertilizes achieved the highest concentration in increasing of nutrients ( N, P, K, Fe and Zn) in the soil and potato tuber compared with all other study factor, comparing to the complete(100%) of fertilizer recommendation by ( 78.67, 33.67, 260, 14.18 and 1.23) mg kg-1except of the Zn elements which approached to the maximum value in 75% level of fertilizer recommendation used. The amount of absorbed nutrients in potato tubers reached to a highest rate when 75% level of fertilizer recommendation which, was used by CX ( 128.5, 35.99, 236.97, 0.983 and 0.246) kg ha-1, respectively. | ||
