Abstract
Agricultural drought is a temporary condition that occurs for a short period of time due to deficient precipitation on vegetation and prolonged deficiency of soil moisture.
This is the result of imbalance between soil moisture and evapotranspiration.
The effectiveness of horticultural practices in conserving of soil moisture and reducing of evapotranspiration area has generally been found to be higher under drought conditions.
The aim of this research was to find the best horticultural practices for reducing agricultural drought damages in the rainfed fig (Ficus carica ‘Sabz’) orchards.
The experiment consisted of 7 treatments and 5 replications and continued for three years.
The best treatments with the best effect on economic and technical characteristics were selected and recommended using the technique for order preference by similarity to ideal solution (TOPSIS) method.
Results showed if we considered yield of tree as the only criterion for selecting the best treatment, the mechanical weeds control would be the most successful method against drought.
But the survey showed that horticulturists consider other factors such as skin color, fruit size, ripening time, ostiole opening, tree damage and operation cost.
On the basis of these factors, application of licorice root residues mulch, severe top pruning and mechanical weeds control were ordered and been the best treatments to reduce drought damage on the rainfed fig orchards.
