Copy link Drone Delivery FertiBuzz Fertilizer Evaluation
Yokakaichi, Mie 2020
Key Conclusions
- FertiBuzz is ideal as a low volume foliar spray, with a very low salt index (SI) and optimum acidity. The results show that both T1 and T2 are safe for ultra-low volume (ULV) application, but FertiBuzz is safer to use.
- FertiBuzz induced lower grain moisture content with no yield or quality reduction, possibly indicating earlier maturity and an earlier harvest.
Objective
To evaluate the feasibility and safety of drone application of ultra-low volume, high concentration FertiBuzz foliar fertilizer, and to monitor its effect on rice performance.
Trial Details
Trial station
Yokakaichi, Mie
Crop
Rice
Treatments
The trial included 3 treatments and 4 repetitions of foliar application by drone. Application was at rice’s max tillering and heading development stages. The water temperature at dissolving was 25 ̊C. Spraying was intentionally overlapped during each foliar treatment. This allowed the edges to be used to assess phytotoxic risk (from the double quantity). The yield survey consisted of 5 plants/row.

- No significant effects on yield parameters were observed.
- Grain moisture was significantly lower in T1 compared to T2 (but not compared to the control). This may indicate earlier maturity following FertiBuzz treatment.
- No other differences in grain quality were significant.
