Other claims from this paper (10)
- Intervention effect Foliar fertilizer treatments significantly decreased yields at some of six responsive sites.
- Observation The mean yield increase or decrease at responsive sites was 400 kg ha −1.
- Intervention effect The 3–8–15 fertilizer caused no leaf damage.
- Intervention effect Other fertilizers caused little or no leaf damage.
- Association Leaf damage was not clearly related to yield decreases.
- Intervention effect Foliar fertilization seldom increased tissue N–P–K composition, nutrient uptake, or photosynthesis at R2.
- Intervention effect Foliar fertilization seldom increased plant weight at R2.
- Association A combination of nutrient availability, vegetative growth, and rainfall explained 27% of variation in yield response.
- Association Positive yield responses tended to occur when soil or weather reduced plant growth and nutrient availability.
- Recommendation Foliar fertilization across all conditions will not offset application costs.
