Experience of using Equilibrium®, Bioiberica's synergistic biostimulant, in almond tree

Friday, 26 March 2021
Field Experience | Frut trees
Objetive:
Effect of Equilibrium® in increasing the size of the almond kernel (Penta).
 
Data:
  • 5 PLOTS (rainfed, irrigated, high density)
    •   Isso
    •   Archivel
    •   Villarobledo
    •   Ciudad Real
    •   Toledo
  • 2 years of study
  • 100 unit data
  • 8 parameters to study
  • Fruit characteristics
  • NUMBER OF DATA: + 64,000
Application times:
1st: Pre-flowering
2nd: Petals fall
3rd: Stone hardening
 
Treatments:
  • Treatment 0: Control.
  • Treatment 1: Pre-flowering.
  • Treatment 2: Post-flowering.
  • Treatment 3: Pre-hardening.
  • Treatment 4: Pre-flowering + Post-flowering.
  • Treatment 5: Pre-flowering + Pre-hardening.
  • Treatment 6: Post-bloom + Pre-hardening.
  • Treatment 7: Pre-bloom + Post-bloom + Pre-hardening.
Equilibrium® dose used: 0.3%
Mixture volume: 1,200 L/ha.
 
Average for each year and treatment for each zone and for each character studied:
Equilibrium Almond Tree 1
 
Results:
Total Average dry weight (shell & kernel):
Equilibrium Almond Tree 2
The 2 applications of Equilibrium® in Pre-flowering & Post-flowering (T4) and the 3 applications in Pre-flowering, Post-flowering & Bone hardening (T7) provide an increase of 17% & 20% respectively to the Total dry weight (shell + kernel) from kernel cv. Penta.
 
Average kernel weight:
Equilibrium Almond Tree 3
The 2 applications of Equilibrium® in Pre-flowering & Post-flowering (T4) and the 3 applications in Pre-flowering, Post-flowering & stone hardening (T7) provide an increase of 14% & 18% respectively to the average kernel weight cv. Penta, a variety characterized by a low kernel weight.
 
Remote sensing: NDVI index tracking
Equilibrium Almond Tree 4
The vigor index (NDVI) remains lower in the treatment with Equilibrium®, which is consistent with the higher proportion of future almonds.
 
Conclusions:
  • The trial, in the Penta variety, in 2 campaigns and 5 localities, with different cultivation systems (rainfed, irrigated and high density), it has shown that the best treatments with Equilibrium® are achieved with 2 and 3 applications of the biostimulant in Pre-flowering, Post-flowering and stone hardening (T7) providing an 18% increase in the weight of the kernel.
  • Likewise, the priority is the early application (2 applications in pre and post-flowering - T4) of Equilibrium®, in Penta variety, that is characterized by a low kernel weight.
