Abstract

ER, F., H. POLAT and F. BAYRAKLI, 2003. Boron content of vineyards and soil in Hadim Aladag part of Konya. Bulg. J. Agric. Sci., 9: 157–160

This Study was made to determine relations between boron content and other plant nutritional elements in soil and plant samples collected from important vineyards area in Hadim Aladag region. Soil and plant samples that taken from 52 vineyards and the results are as follow.

• The Boron content of soil samples at 0–30 cm depth is between 0.05–4.33 ppm and at 30–60 cm depth it's between 0.05–3.96 ppm.
• Available boron content of plant samples at fruit set period in leaf blades is ranging between 29.75–105.80 ppm and in leaf petiole it's ranging btw. 19.8–59.8 ppm.
• At veraison period, in leaf blade it's ranging between 18.30–42.00 ppm.
• Available boron content of plant sample's shows a decrease from fruit set period to veraison period. Moreover, it was confirmed that; Boron content of leaf blades is more than that of leaf petiole's.
• Statistically important positive relations were fond between. the B / Ca ratio of leaf petiole and leaf blade's of plants and available boron content of soil (**P < 0.01).
• Statistically important positive relations were found between The Boron content of leaf petiole and blades and The boron content of soil (**P < 0.01).
• Statistically important negative relations were found between Ca content of leaf blades and available boron content of soil at 30–60 cm depth (*P < 0.05). Statistically important negative relations were found between. The clay content of soil and boron content of leaf petiole (*P < 0.05).
