The field trial, conducted in Thailand, tested the effect of three foliar applications of multi-npK (13-3-43) as the rice fertilizer, compared to the traditional growing method. The results: increased yield and revenue
Agronomic effect of three foliar applications with multi-npK (13-3-43) was examined. Difference in yield and net profit was compared to the traditional growing method.

Crop/cultivar |
Rice / Suphan 1 ( a long season cultivar) |
|---|---|
| Country / location | Thailand / Lamphaya / Banglane / Nakornpatom/ Suphan-Niam’s farm |
| Objectives | Increase yield |
| Haifa product tested | Multi-npK (13-3-43) |
| Application method | Foliar nutrition |
| Tested treatment | 3 x foliar sprays @ 360 lit/ha (Knapsack sprayer); 33, 64, 81 days after planting @ 2%, 3%, 3%, respectively. |
| Control treatment results | Total yield: 6.6 MT/ha Grower’s revenue from yield: 171 US$/Ha |
| Best treatment results | Total yield: 8.2 MT/ha Grower’s revenue from yield: 212.4 US$/Ha |
| Characteristics of best treatment | Yield increase: 1.6 MT/ha (24% above control) Cost of treatment (application + material) 31.5 US$/ha |
| Net benefit of best treatment | 9.9 US$/ha |
| Benefit/Cost ratio | 9.8 |
| Conclusions | This result is in good agreement with many previous experiments showing high contribution to foliar feeding of rice with Multi-K as rice fertilizer |
The bottom line:
The foliar application with Multi-npK 13-3-43 increased the yield by 1.6MT/H and the revenue by 41.4 USD/Ha. The net income increased by 9.9 USD/Ha. This application will give best economical results when the grain prices are high or when agronomic condition is expected to be difficult.
