Abstract

The effect of girdling and/or a mixture of micronutrients (containi 9 0.05% chelated Zn, Fe and Mn and 0.05% boric acid) and a mixture of macro nutrients (containing 0.5% from each of urea, orthophosphorlc acid, potassium sui hate and magnesium sulphate) on growth. flowering, yield and fruit quality of Manz.aniUo olive trees grown In sandy soil were investigated during 2001 and 2002 season . Bearing branches were girdled at one week before full bloom Nutrients were sprayed four limes in the fi rst week of Aprit, May, June and July in both seasons. Girdling and/or spraying nutrients were effective in stimulating shoot length. number of leaves/shoo, leaf area, yield, mean fruil weight, pulp weight % a d oil % in the putp as compared with the ched treatment. The studied treatment had an announced (eduction on seed weight %. The enhanCing effects or the treatments on the number of inflorescences Ishool and number of flowerslinflorescence we e proved slali~ticaly, only In the seconc experimental season. The promotion on these characters was associated with carrying out girdling, using micronutr'ents and macronutrients, in ascending order: A synergistic innuence on growth and fruiting was ob&erved when application or nutrients was accompanied with girdling compared to establishing each alone. The striking treatment responsible for Improving yield in quantity and quality of MsnzaniIJo olive trees Included girdling the bearing shoots and the use of special nutrient mixture containing 0.5% from urea, orthophosphorlc acid, potasslum sulphate and magneSium SUlphate as well as 0.05% chelated Zn, Fe and Mn and 0.Q5% borlc acid.
