Interpretive Summary:

Technical Abstract: Container nursery production requires large inputs of water and nutrients but frequently irrigation inputs exceed plant demand and lack application precision or are not applied at optimal times for plant production. The results from this research can assist producers in developing irrigation management strategies that minimize nutrient effluent as well as produce a quality container grown tree. Overall, plants had more height and trunk growth when irrigated mostly in the afternoon compared to early morning irrigation. Reducing the volume of irrigation with a tri-cyclic irrigation regime did not affect height growth, but reduced the trunk diameter growth. Irrigation emitters had an effect on plant growth and levels of electrical conductivity, nitrate-N, and ortho-P leachate effluent. As a result, modifying cultural practices could be a viable tool for irrigation and nutrient management.
