This study was conducted to determine the boron (B) status of apple orchards and examine the relations among B nutrition and some soil properties in Isparta province. For this purpose 250 gardens from the seven districts of the region were determined and soil and leaf samples were collected. In order to determine soil and leaf B status and relations among these some soil properties were determined. Similarly, other leaf nutrient concentrations were analyzed. According to the soil analysis it was seen that most of the soils are B-sufficient. If soil B concentrations were evaluated depending on the district, the lowest soil B (0.26 mg kg-1) was measured from the gardens of Senirkent, the highest B concentration (3.44 mg kg-1) was determined in Atabey. Looking at the individual districts, all apple orchards in Gönen and Keçiborlu have sufficient (0.5-2 mg kg-1) soil B. Also in Yalvaç, Atabey, Gelendost and Eğirdir 71%, 95%, 96% and 97% of the soils had higher B concentration than B deficiency level (0.5 mg kg-1). The most soil B deficiency problem was observed in Senirkent and Yalvaç. Average soil B levels for Atabey, Eğirdir, Gelendost, Gönen, Keçiborlu, Senirkent and Yalvaç orchards were calculated as 1.32, 0.96, 0.87, 0.67, 0.91, 0.49 and 0.62, mg kg-1 respectively and general average were determined as 0.84 mg kg-1. Depending on leaf analyze results, it was seen that 94.8% of the trees had sufficient B and only 5.2 percent of trees had B deficiency. According to the results, there is not B deficiency in 85 % of the soils. And this reflects the leaf analysis as well. Although this result, there was not seen any correlation between soil and leaf B concentrations. But, there were negative correlations among available soil B and soil pH and Ca. Positive correlations were determined among soil B concentrations and other micro nutrients. While a negative correlation between leaf B concentration and leaf P was found, there was a positive correlation between B and Mn.
