Research Project: Improving Pomegranate Fertigation and Nitrogen Use Efficiency with Drip Irrigation Systems

Location: Water Management Research

Project Number: 2034-13000-011-19
Project Type: Reimbursable

Start Date: Jan 01, 2013
End Date: Jan 31, 2016

Objective:
Determine real time seasonal nitrogen requirements to improve FUE of mature pomegranates using drip and subsurface drip irrigation. Determine required level of nitrogen to maintain N levels in mature pomegrantes. Determine effect of N fertilization on macronutrient concentrations.

Approach:
The project will use a complete randomized design of 2 irrigation treatments and 3 fertilization treatments with 5 replications. The water requirement will be determined by weighing lysimeter and the fertiliztion will be determined by tissue sampling. This is a field project on 2 acres.
