Country / locationBrazil / State of Sao-Paolo / University of Jaboticabal
ObjectivesIncrease yield
Haifa product testedMulti-K
Application methodFoliar nutrition
Tested treatment2 foliar sprays @ 1.0% concentration & 400lit./ha,

Control treatment results2,801 kg/ha
Grower’s revenue from yield: 183 US$/MT
Best treatment results3,340 kg/ha
Grower’s revenue from yield: 183 US$/MT
Characteristics of best treatmentYield 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$/ha
Net benefit of best treatment0.539 x 183 – 5.6 = 93 US$/ha
Benefit/Cost ratio0.539 x 183 / 5.6 = 17.6
