Other claims from this paper (17)
- Intervention effect Foliar fertilization increased soybean yields at seven sites.
- Intervention effect Foliar fertilization decreased soybean yields at two sites.
- Intervention effect Foliar fertilization increased mean soybean yield by 60 kg ha −1 in 1994, not significantly.
- Intervention effect Foliar fertilization increased mean soybean yield by 30 kg ha −1 in 1995, not significantly.
- Intervention effect Foliar fertilization increased mean soybean yield by 60 kg ha −1 in 1996.
- Intervention effect Foliar fertilization increased mean soybean yield by 54 kg ha −1 across the 48 sites.
- Intervention effect A single 28 L ha −1 foliar application gave the highest mean yield increase across responsive sites, 375 kg ha −1.
- Observation Differences between foliar fertilization treatments in soybean were small and inconsistent.
- Association In 1994, higher soybean yield responses to foliar fertilization occurred when plant P concentration was low.
- Observation No foliar fertilization treatment caused soybean leaf burning.
- Intervention effect Foliar fertilization seldom increased P and K concentrations of soybean leaves at the R2 stage.
- Intervention effect Foliar fertilization did not affect soybean maturity, grain moisture or grain weight.
- Observation No simple set of measured variables explained the occurrence of soybean yield responses to foliar fertilization.
- Association Soybean yield responses to foliar fertilization tended to occur when plant-available P was low.
- Association Soybean yield responses to foliar fertilization tended to occur when spring and midsummer rainfall was low.
- Observation The group of tested variables explained only 14 to 23% of soybean yield responses across years.
- Recommendation Effective foliar fertilization of soybean in predominantly high-testing soils needs further research on conditions with positive responses.
