Foliar nutrition increased Soybean grains weight

 

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
Grower’s revenue from yield: 183 US$/MT

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.
