Effect of Terra-Sorb® and AminoQuelant®-K application on production and fruit size in avocado

Avocado is a very important crop worldwide, which adapts to very different edaphic and climatic conditions.

The characteristics of this crop, specially its great vigor, its slow production start and the adverse factors to which flowering and fruit setting are subject to, entail a high production variability.
Thus, crop management is very important in order to ensure a larger haverst.
This trial has evaluated the application of Terra-Sorb® 4 macro radicular (application through drip irrigation) and AminoQuelant®-K (foliar application) to determine whether they can be helpful to increase production in this crop.

Trial data

ORGANISM: Agrogest.
LOCATION: Salvador Heredia's estate, Vélez-Málaga. Málaga.
VARIETY: Hass.
PLANTATION AREA: 8 x 4 m.
AGE: adult.

Experimental design

TREATMENTS:

• Control: untreated.
• Terra-Sorb® 4 macro radicular + AminoQuelant®-K: 43 l/ha + 12 l/ha.

PLOTS

APPLICATION

The first application of Terra-Sorb® 4 macro radicular starts with the beginning of flowering.

Results

Conclusions

• Applying Terra-Sorb® in avocado crop from flowering until fruit development has a very positive effect on fruit setting and fruit retention.
• The important production increase thanks to Terra-Sorb® and AminoQuelant®-K treatment is observed in all commercial categories.
• AminoQuelant®-K application seems to have a positive effect on fruit size and production; however, a correction of the fertilization program is recommended to adjust it to the number of fruits set.
