Friday, 26 March 2021
Field Experience | Frut trees
Objetive:

Effect of Equilibrium® on the increase of almond kernel size (Penta).

 
Information:
  • 5 PLOTS (rain fed/non-irrigated, 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: Petal fall
3rd: Pit 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.
Dose of Equilibrium® used: 0.3%
Mixture volume: 1,200 L/ha.
 
Meanfor each year and treatment for each zone and for each character studied:
Equilibrium Almond Tree 1
 
Results:
Total Mean 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.
 
Mean 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:

  • For the trial on the Penta variety of almond trees over 2 seasons and in 5 locations using different cultivation systems (rainfed/non-irrigated, irrigated, and high density), it has been seen that the best treatments with Equilibrium® are obtained with 2 and 3 applications of the biostimulant at the Pre-flowering, Post-flowering, and Pit hardening (T7) stages, providing an 18% increase in kernel weight.
  • Also, priority is given to the early application (2 applications in pre-flowering and post-flowering – T4) of Equilibrium®, in the variety cv. Penta, which typically has a low seed weight.
