Abstract

The experiment was carried out during 2008 to 2009 and 2009 to 2010 with the aim to study the effect of girdling and foliar application of zinc and boron on growth, quality and leaf nutrient status of olive cv. Frontoio. The experiment was laid out in a randomized block design with seventeen treatments. Maximum shoot extension growth (8.92 cm) was observed with the spray of 0.6% ZnSO4 in combination with 0.6% boric acid. Maximum pulp:stone ratio of 2.57 and oil content of 25.62% was recorded with the foliar application of 0.6% ZnSO4 in combination with 0.6% boric acid and 0.6% ZnSO4 in combination with 0.4% boric acid, respectively. The highest leaf K (1.74%), Ca (1.71%) and Mg (0.15%) contents were recorded with spray of 0.5% ZnSO4 in combination with 0.4% boric acid, 0.5% ZnSO4 in combination with 0.5% boric acid and 0.6% ZnSO4 in combination with 0.6% boric acid, respectively. From this study, it is concluded that foliar application of zinc sulphate in combination with boric acid resulted in better growth, physical characteristics and oil content of olive fruits.

 

Key words: Olive, girdling, zinc, boron, leaf nutrient, oil content.
