There are more than 37,000 hectares of land cultivated with date palm in Hormozgan Province producing around 145,000 tons of date annually. Therefore, increasing date yield and quality can ender positive effects, especially on farmers, income in the region. One of the most important agricultural practices is mineral nutrition nd soil fertility management that can improve yield and fruit quality of date palm.
This research was conducted for a duration of three years to study the effect of essential nutrients application on Date Bunch Wilt and ry disordr (DBWD) which has caused large production reductions in recent years. Two palm groves of “Mordasang” cultivar were chosen as experimental sites. One was afflicted with DBWD and he other one healthy.
Fertilizer treatments were applied on the basis of soil and leaf nalysis as follows:
1- Control (with no use of fertilizers)
2- Addition of balanced amounts of macro-nutrients and
3-Addition of balanced amounts of macro as well as micro-utrients. Theexperiment was arranged with a complete randomized block design of five replications. Maintenance operations consisted of pollination, weeding, disease and pest control. Such plant esponses as fruit yield, bunch number and percentage of bunches fflicted by DBWD were determined and compared among treatments. There was no significant difference observed between bunch numbers per tree in the fertilizer treatments. Application of ssential nutrient elements (treatments 2 and 3) resulted in a onsiderable increase in date yield and a decrease in dried bunches percentage.
