This project is an continuation of an objective of existing CRDF funded project (# 00124558 ; ended in March 2019, final report submited to CRDF) with some added treatments to be evaluated in comparison to control (dry conventional fertilizer with foliar micronutrients). Objective 1 which is the continuation of # 00124558 included 10 treatments.
The added treatments from objective 2
1. CRF + Tiger Micronutrients+ Mn 50%
2. CRF + Tiger Micronutrients+ Zn 50%
3. CRF + Tiger Micronutrients+ Fe 50%
4. CRF + Tiger Micronutrients+ B 50%
5. CRF + Tiger Micronutrients+ Mn +Zn 20%
6. CRF + Tiger Micronutrients+ Mn +Fe 20%
7. CRF + Tiger Micronutrients+ Zn +Fe 20%
8. CRF + Tiger Micronutrients+ Zn +B 20%
9. CRF + Tiger Micronutrients+ Fe + B 20%
10. CRF + Tiger Micronutrients+ Mn +Zn 50%
11. CRF + Tiger Micronutrients+ Mn +Fe 50%
12. CRF + Tiger Micronutrients+ Zn +Fe 50%
13. CRF + Tiger Micronutrients+ Zn +B 50%
14. CRF + Tiger Micronutrients+ Fe + B 50%
The treatment for objective 3:
1.CRF + Foliar Micronutrients + Tiger 90;
2.CRF + Tiger Micronutrients
So altogether currently there are 25 treatments of citrus nutrition that are being compared to control.
These treatments have been initiated at all sites in spring of 2019. The pretreatment data and first and second round of fertilizer application have been already made. The leaf and soil nutrient analysis has been completed and currently we are interpreting the data. Overall, the trees are looking good and they have a good crop load.
The yield and consumer panel results from Objective 1 have been presented at Citrus Expo 2019. These results will be additionally presented at SWFREC and CREC on October 29th, 8th, respectively.’
This a fertilizer evaluation trial and the progress on it is timely and as per expectations
