Abstract: 

The study was conducted under greenhouse conditions, to study the effect of potassium- accompanying anion on the relationship of quantity and intensity ratio (Q/I) of soil potassium, as well as to determine its correlation with soil characteristics and plant indicators of wheat (Triticum aestivum L.) in Abyek of Ghazvin region. A factorial experiment with a complete random block design was carried out in 3 replications, in which 21 soil samples were considered as the first factor and 2 fertilizer levels of 0 and 100 mg/kg of potassium, as the second factor. In order to determine the effect of potassium - accompanying anion on Q/I relationship of soil potassium, two solutions (potassium chloride and potassium sulfate) were used. The effect of potassium-fertilizers on wheat yield was significant (p=0.05), and effect of soil characteristics on yield was significant at 1 percent level. PBCK showed a strong correlation with CEC (r=0.969**), clay percentage (r=0.908**), and percentage of soil saturation (r=0.872**). The following equation was suggested for estimating the buffering capacity for soils under wheat cultivation. PBCK=7.419 CEC - 19.743, R2adj=0.782 The correlation between available potassium DK0 and ARek with the potassium absorbed by the wheat and its relative yield did not show any significance. However, PBCK illustrated a strong correlation with the potassium absorbed by the wheat (r=0.714**) and its relative yield (r=0.735**). The PBCK resulting from the two potassium solutions showed a significant difference at 5 percent. A difference at 1 percent was also seen between DK0 resulting from these two solutions. However, their ARek showed no significance. The correlation between Q/I parameters, resulting from the two potassium solutions, with soil characteristics did not show a significant difference. However, in regards to correlation with plant specifications, there was a significant difference between these two solutions, with potassium chloride having a greater preference in determining the relationship between Q/I and soil potassium.
