1. The relationship between boron deficiency of Golden Delicious and boron content in leaves and soil was investigated at the 153 orchards in 1968, and 149 orchards in 1969. Deficient orchards were estimated 24.2 per cent (1968) and 18.2 per cent (1969) of all investigated orchards.<br>2. The mean values for water soluble boron in soils were 0.62ppm in the range from 0.16 to 2.48 ppm in 1968, and 1.03ppm in the range from 0.36 to 4.09ppm in 1969.<br>3. The negative correlation of 0.537 (1968) and 0.420 (1969), significant at 0.1% level, existed between degree of deficiency and boron content in leaves. The mean values of leaf boron for deficient orchards in both years were 8.1 and 8.6ppm respectively, against 12.1 and 12.4ppm for non deficient orchards.<br>4. The positive correlation of 0.433 and 0.358 in both years, significant at 0.1% level, existed between boron in soils and in leaves. These results in both years suggested that orchards of lower than 1.0ppm soil boron and of lower than 15ppm leaf boron were subject to the occurence of boron deficiency, and in fact more than 30 per cent of such orchards showed deficiency distinctly in observation.
