| Abstract | A pot experiment was carried out in the greenhouse of Soil and Water Dept. , Faculty of Agriculture, University of Sana'a during 2008 season on a sedimentary salty clay soil, to study the effect of different levels of potassium and phosphate fertilizer in the growth and NPK contents of bean plants. The experiment was designed using a split plot design with three replications where phosphate levels were the main plots and potassium fertilization levels were the sub plots .Three levels of phosphate fertilizer, (superphosphate triple 21% P, 0.60, 120 kg P / ha.).were examined and have been given the following codes (P3, P2, P1), respectively. Four levels of potassium fertilizer (potassium sulfate ,42% K; 0,50, 100, 150 kg K / ha. ) were also used and have been given the following codes (K4, K3, K2 , K1), respectively. Nitrogen fertilizer in the form of urea was added for all transactions at the rate of 60 kg N/ ha after germination. The third level (P3) of phosphate fertilizer (120 kg / ha) was significantly increased plant height and number of branches / plant and root length and weight of the dry matter , while the the second level (60 kg P / ha) had the superiority to increase dry weight of roots. Also add phosphate fertilizer caused a significant increase in the concentration of P in plant tissues while insignificantly influence on the nitrogen content of the plant was detected . Meanwhile, potassium content of the plant was reduced due to the addition of P levels . Add potassium fertilizer led to a significant increase in the aforementioned diameters and the best significant effect of potassium fertilizer was recorded at the third level (100 kg K / ha) and fourth (150 kg K / ha). Resulted data showed that the interaction between potassium and phosphate treatments gave significant increases in the studied parameters, the treatment P3K4 highest produced the highest values of plant height , dry matter , root length and the concentration of potassium in the plant ; while the treatment P3K3 resulted in a significant increase in dry weight of roots and content of nitrogen. P3K2 treatment led to significant increase in the phosphorus content of the plant. |
