FRUIT / BERRY: Tomato, “Alpha” variety

PRODUCT: Fe20 (foliar application)

YEAR:  2023

COUNTRY: Kazakhstan

‍

APPLICATION:

1. Control. NPK background.
2. Background NPK + Fe20. Foliar application: 1st - 10 days after seedling planting, then 2 more times with a 14-day interval, product consumption - 0.5 kg/ha, working solution consumption - 300 l/ha. (Variant 1).
3. Background NPK + Fe20. Foliar application: 1st - 10 days after seedling planting, then 2 more times with a 14-day interval, product consumption - 1.5 kg/ha, working solution consumption - 300 l/ha. (Variant 2).
4. Background NPK + Fe20. Foliar application: 1st - 10 days after seedling planting, then 2 more times with a 14-day interval, product consumption - 3.0 kg/ha, working solution consumption - 300 l/ha. (Variant 3).

‍

Trial plots area – 10 m², observed plots area – 5 m². Trial repetitiveness — four times.

‍

RESULT:

1. Yield increase compared to control with NPK background: 8.7-25.78%.
2. The yield increase resulted from improvements in yield structure: the number of fruits per plant increased by 8.8-32.9%, and the size of the fruits increased by 10.2-22.4%.
3. Quality indicators improved: vitamin C content increased by 3.6-19.6%, and the total sugar content increased by 0.3-0.8% (in absolute values).
4. The maximum result was achieved with a double application at a 3.0 kg/ha dose.
5. All yield increases exceeded the experimental error and were statistically significant.
