| Abstract | ||||
| To study the effect of different levels of potassium and phosphate fertilizers on some soil chemical characteristics in glass house affiliated to Soil and water department, Faculty of Agriculture, Sana'a University in the season of 2008. Split Plot Design with three replicates where such fertilization phosphate represent main factor and potassium fertilization sub plots consisted of transactions in the three levels of phosphate fertilizer Super triple superphosphate (21% P (is (0, 60, 120) kg p / ha and given her the following codes (P3, P2, P1), respectively, and four levels of potassium fertilizer potassium sulfate (41.5% K) are (0, 50, 100, 150) kg K/ha have been given the following codes (K4, K3, K2, K1) respectively, nitrogen fertilizer was added in the form of urea to all at once by 60 kg N/ha transactions after germination. The statistical analysis results showed that the adding of phosphate fertilizer to soil led a significant increase in the soil content of some including nutrient elements. The third level (P3) 120kg/ha has significantly increasing the phosphorus, calcium , magnesium, and sodium dissolved, as well as the degree of soil interaction and electrical conductivity in the second level P2 has dominated in terms of exchange potassium increase in soil. Also, fertilizer potassium increase significantly the soil content of some nutrients at the fourth level K4 of potassium dissolved, mutual and ready, as well as electrical conductivity, and did not impact significantly on the phosphorus, calcium, magnesium and sodium dissolved. potassium and phosphate fertilizer overlap to a significant increase in the properties of the previous soil, as treatment p < sub>2K4 gave the highest rate in the soil content of potassium dissolved and mutual, as well as the degree of soil interaction while p < sub>3K3 treatment led to a significant increase in the soil content of phosphorus ready and magnesium dissolved in while P3K4 treatment led to a significant increase in the soil content of sodium dissolved, as well as electrical conductivity. | ||||
