Research Project: Fertilization of Pomegranate with Drip Irrigation

Location: Water Management Research

2011 Annual Report

1a. Objectives (from AD-416)
Determine real time seasonal N requirements of drip irrigated pomegranates. Determine the effect of three nitrogen injection rates on the N leaching loss.

1b. Approach (from AD-416)
A field experiment will be conducted on 3.3 acres of land with 3 levels of N injection with surface and subsurface. The effects on tree development and fruit quality will be measured.

3. Progress Report
This Specific Cooperative Agreement supports objective 1 of the parent project. This project is to evaluate the fertilizer requirements for a developing pomegranate crop. The fertilizer injection system was installed and uniform levels of N and P were applied through the drip system to establish the crop. The full irrigation requirement of the crop was met based on water use determined by a weighing lysimeter located in the field. The lead scientist regularly meets with the field staff and visits the site to confirm the operation of the project.
