SA03WB-03: Pre and post nutrition management

<< BACK TO R&D TRIALS


Research Site / Demonstration Number: SA03WB-03
Grower Collaborator: Littabella Pines
Location 3: South Littabella Road, Yandaran
Initiation Date: January 2019


OUTLINE

To develop and evaluate an improved pre-plant and post-plant nutrition program to improve Smooth Cayenne and 73-50 fruit quality and yield. Grown in light to moderate textured soil with a low pH.


OBJECTIVES

  1. To investigate and improve the elemental ratios, frequency and timing of foliar fertiliser programs.
  2. To investigate and improve pre-plant and post plant nutritional programs with a focus on the reducing fertiliser inputs.
  3. To undertake a cost analysis of the different nutritional program compared to standard practices.
  4. To increase yield and fruit quality in plant and ratoon crops.

METHODOLOGY

The trial site has followed a previous crop of Smooth Cayenne which was taken to plant and ratoon crop.  The previous crop was harvested in spring 2018 with major issues of Phytophthora root rot, nematode and black beetle/white grub.

The soil was prepared to standard industry conditions with good soil tilth, no crop residue, good soil moisture and a soil pH of 4.2.  Weather leading up to application had good rainfall with temperatures ranging from 20 – 30°C.  The trial was planted with Smooth Cayenne and 73-50 tops.
