Country / location | 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 Grower’s revenue from yield: 183 US$/MT |
Best treatment results | 3,340 kg/ha Grower’s revenue from yield: 183 US$/MT |
Characteristics 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. |
