Sažetak

This experiment was conducted to explore the reasons of difference between ‘Zard’
olive orchard with the poor vegetative growth rate and fruit set and orchard with suitable
vegetative growth rate and fruit set in relation to some soil and plant factors during two
seasons. Note that assumptions were based on the overall canopy greenness of the
olive trees, so experimental orchards in which the planted trees showed optimum leaf
greenness were considered good situations for optimum vegetative growth and
productivity. Remote sensing technologies based on normalized difference vegetation
index (NDVI) were employed on olive orchards, and two orchards meeting the criteria of
highest amount of greenness and lowest amount of greenness were selected. Length of
current-year shoot (LCYS) and fruit set were considered indicators of tree vegetative
growth and productivity, respectively. Results clearly indicated a significant difference
between the two selected orchards in terms of canopy volume (CV), leaf nitrogen
content (N), leaf potassium content (K), silt, sand, Sodium adsorption rate (SAR),
available phosphorous (Pavi), total neutralizing value (TNV), electrical conductivity (EC),
chloride (Cl), and Fe variables. A stepwise regression method was used to evaluate the
effects of soil and plant variables on fruit set and LCYS. According to the obtained
results, the main reasons for differences between two orchards in fruit set and
vegetative growth was N and K deficiencies, soil salinity, and a high percentage of silt in
the soil.
