Almond Pollination Trials
Perennial Horticulture Development Project Kabul, Afghanistan The PHDP has collected some 99 clones. To test all the combinations for incompatibility, there would need to be nearly 10,000 individual crosses. There are many clones collected which have little immediate commercial value, so the work on testing incompatibility will be less than that. The work will also be easier when the germplasm is collected into the reference collections. However, due to the total lack of knowledge in the country about pollination compatibility, it was considered an urgent priority for PHDP, and a simple trial at three sites was designed, using the original in situ trees from which the budwood for the germplasm collection was collected.
Almond Export Market Assessment
Perennial Horticulture Development Project Kabul, Afghanistan The easiest way to make an assessment was to ask the traders to give a price per seer (7kgs) which is the usual trading practice. The exchange rate of the Afghani at the time was 50 Afs= US$1.00. The trader was asked to provide his offer price, which is nearly equivalent to a farmgate price. The two traders were asked to make their assessments independently, and while there is a broad consistency between the two traders, there are some differences....

Impact of Bees and Other Cultural Practices on Almond Yield
Report developed by Mohammad Sharif, Roots of Peace Horticulturalist J.D. “Zach” Lea, Ph.D., Roots of Peace Country Director - Almond Industry Development Project (AIDP) EC Perennial Horticulture Development Project (PHDP) Funded by the European Union. The data from our studies show that use of the package of cultural practices (not including bees) promoted by the Almond Industry Development Project (AIDP) can increase almond yield on traditionally managed Afghan almond trees by 46% to 154%. The use of bees to increase pollination can increase almond yield on traditionally managed Afghan almond trees by 40% to 160%. Thus, the ADIP objective of demonstrating a 35% increase in almond yield attributable to project-promoted cultural practices is achieved. The results of this study are adequate to support a generalized recommendation that improved cultural practices, including the appropriate use of agricultural chemicals, and bees can result in a significant increase in almond yield per tree over that of traditionally managed trees. However, the specific levels of chemicals and bee hives used here should not be considered a recommendation for general use. Instead, these results should to be used only to guide further research, supported by competent integrated pest management principles, into the specific practices to be used in any given orchard.
