摘要

Olive is cultivated as a commercial crop in most parts of Iran. Fars province has the first rank in this country according to this crop. The present study was carried out in the southern part of this province, in Fasa city. Farmers confronted to alternate bearing, low agricultural soil depth, low quantity and quality of this crop, so the research was done in order to solve these problems. Treatments comprised boric acid and zinc sulphate at (0, 2000, 4000 mg L-1) and urea at (0, 5000, 7500 mg L-1) on olive fruit (length, diameter, weight) by foliar application at two harvest stages. The results showed that the most fruit weight, diameter were observed in the treatment with zinc sulphate applied at 4000 mg L-1 alone, but in fruit diameter was seen in zinc sulphate at 2000 mg L-1 plus boric acid at the same concentration and 5000 mg L-1 urea at first harvest. The highest fruit weight, diameter and length were seen at 5000 mg L-1 urea, 4000 mg L-1 zinc sulphate along with boric acid at 4000 plus 7500 mg L-1 urea, and 4000 mg L-1 boric acid alone at second harvest, respectively. In general, use of urea, boric acid and zinc sulphate were effective.
