Effects of organic fertilizer application on yield, soil organic matter and porosity on kilis oil olive variety under arid conditions

Plant and soil must use fertilizer in order to maintain productivity in agricultural production. High-oil olive varieties are grown which has specific high economic value and locally in Kilis city under dry conditions. Kilis oil olive variety has produced without fertilization in dry conditions, in our city. It is necessary to fertilizer the soil and plant in order to ensure sustainability in agricultural production. If agricultural production made from non-fertilizer of plant and soil, soil physical conditions are degraded becomes poor and low yield is emerged. In this study, Kilis olive oil variety which is important variety in our country, they are 38years old and 25 kg/tree, 50 kg/tree and 75 kg/tree farm fertilizer was applied to them. As a result of the study, soil porosity values ranged from 36.2% and 55.8%. The highest porosity value was measured from 75kg/tree organic fertilizer application. Soil organic matter was determined to be 2.28% with soil organic matter while it was 0.95% with traditional application. The highest olive yield was obtained from 75kg/tree organic fertilizer application . Close results were obtained at 50 and 75 kg/tree fertilizer doses therefore 50kg fertilizer dose is recommended for olive producers.
