A significant increase in yield and weight of grains was obtained following two foliar applications of Multi-K
|
Crop/cultivar |
Soybeans / Ocepar-14 |
|---|---|
| Country / location / date | Brazil / State of Sao-Paolo / University of Jaboticabal |
| Objectives |
Increase yield |
| Haifa product tested | Multi-K |
| Application method | Foliar nutrition |
| Tested treatment |
2 foliar sprays @ 1.0% concentration & 400lit./ha, pH adjusted to 5.5. 1st appl. at full flowering, 2nd appl. 18 days later. Harvest took place after 107 days of growth |
|
Control treatment results |
2,801 kg/ha |
| Best treatments results | 3,340 kg/ha Grower’s revenue from yield: 183 US$/MT |
| Characteristic of best treatment | Yield increase: 539 kg/ha (19.2% over control) Ave. weight of the grains was increased by 13-30% Cost of treatment (application + material) 5.6 US$/ha |
| Net benefit of best treatment | 0.539 x 183 – 5.6 = 93 US$/ha |
| Benefit/cost ratio | 0.539 x 183 / 5.6 = 17.6 |
| Conclusions | Try next year more applications. Extremely low precipitation did not allow for full benefit from the treatments. |
