Abstract

The aim of this research was to study organic and mineral fertilization treatments and its effect on some Soil Chemical properties Was included pH, EC .O.M and CEC and yield and growth of cucumber plant (Cucumis sativus L. ) Used split plot design with three replicates. This research is implemented in research farm of Horti. Oapt. Fac of Agric during season 2020. For that Humic Acid (HA) as Organic fertilization and DiAmmonium-Phosphat for mineral fertilization. Used HA at four concentration (H0, H1, H2, H3) g/L and for DAP three concentration (37.0, 75.0) Kg/h Where used. A results demonstrated that. there is significantl effect on soil and plant parametes due to both fertilizations. treatments. The results showed that, the H.A and DAP treatments led to improvment yield and vegetative growth comparing with control treatmen. The best treatment was which had the fertilization adding by HA concentration of H4 and 75kg/ th with DAP fertilization. Also HA and DAP treatment led to improvment the chemical soil properties in comparing to control. In general, The HA treatments manifest the increase comparing with DAP and control treatments.
