To study the effect of adding organic fertilizer to the soil or spraying plant in qualitative characteristics and mineral content of the plant Squash. An experiment was carried out in the greenhouse of the department of Soil and water Faculty of Agriculture - Sana'a University  - in the spring season of 2010 in the soil of sedimentary Silty Clay loam used plastic pots for planting experiment added soil to pots 10 kg soil / pot. The experiment was designed using a split plot design with three replications. The ground organic fertilizing called the Pew Ho Moses component (25% humic substances and NPK and trace elements (Mn, Ca, B, Mo, Zn, Co, Fe) main pieces and add to the soil in three levels, namely, (0, 20.40 ) t / ha and have been given the following codes (F1, F2, F3), respectively, add compost ground into the soil and mix well before planting by the addition levels. organic fertilizer spray, called Homistar component of the same former fertilizer components and concentrations less sub-blocks in three levels, namely, (0, 20,40) me / L, was added to plants by spraying and have been given the following codes (S1, S2, S3) to levels previously mentioned was spraying fertilizer organic liquid on plants in two installments the first spray after 21 days of germination and the second after 15 days Spatter from the first by the addition of various levels, were planted the seeds of the plant Squash (Alzukina) class, was added stimulus of nitrogen fertilizer on the form of urea 46% N at a rate of 30 kg N / ha for all  treatments. Spraying the plant by organic fertilizers increased fresh weightm and dry matterm significantly. Mean while, increased TSS andNPK content especially at the third level 40 mL.L^-1.
