Abstract
The experiment was conducted in the lath house of tikrit university using plastic pots with 36cm diameter which was filled by peatmoss and loam soil at 1 : 2 ratio. The experiment included two factors : Soil inoculation treatment with cyanobicteria (with and without) and the second factors (spraying with sea algae extracts which were used in to four levels : E0 (control) E1(spraying with 2 ml/l from seaforce1 alage extract), E2 (spraying with 2 ml/l from seamino alage extract), E3 (spraying with 2+2 ml/l from seaforce1 and seamino alage extract) complete block with four replications. The solution applied as foliar application the first application was carried out after two weeks from the first. The results could be summarized as follow: 1.Inoculation with cyanobicteria significant increase in yield and its compotes. 2.Spraying with sea alage extracts gave scientifically increase in yield and its components especially in case the plants which were sprayed with mixture of sea alage extracts. 3.The effect of interaction between cyanobicteria inoculation and sprying with sea alage extracts was significant which the treatment using cyanobicteria inoculation with spraying mixture of seaforace 1 and seamino alage extracts (2+2 ml/L)respectively gave the highest values of fruit weight ,size number values in fruit and total yield 4.each of cyanobaceria inoculation and spraying with sea alage extracts caused significant increase in the concentration of nitrogen, phosphorus and potassium. 5.Interaction between the two studied factors was significant in concentrations for the three nutrients, where the treatment using cyanobicteria inoculation with spraying mixture gave highest concentration of nitrogen, phosphorus and potassium .
