Soybean Yield and Nutrient Composition as Affected by Early Season Foliar Fertilization

Mazhar U. Haq; Antonio P. Mallarino Agronomy Journal 2000. doi:10.2134/agronj2000.92116x

Other claims from this paper (10)

Intervention effect Foliar fertilizer treatments significantly increased yields at some of six responsive sites.
Intervention effect Foliar fertilizer treatments significantly decreased yields at some of six responsive sites.
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.

CHALLENGES OF POST-HARVEST RESIDUE MANAGEMENT IN THE LOUISIANA SUGARCANE INDUSTRY

Ryan P. Viator; Richard M. Johnson; Edward P. Richard 2005

Other claims from this paper (10)

Intervention effect Winter soil temperature was lower with residue left in place than with residue removed.
Intervention effect Winter soil moisture was higher when residue remained than when removed.
Observation Most cultivars had similar responses to residue conditions.
Intervention effect Nonremoval reduced sugar yield by 0.7 tlha compared with January residue removal.
Intervention effect Mechanical residue removal and burning produced similar yields.
Intervention effect Burning residue after January reduced sugar yield by 1.2 tlha.
Recommendation The authors recommend January removal by burning or mechanical means.
Recommendation The authors recommend mechanical removal after January.
Association Higher moisture and lower soil temperature under residues appear related to sugarcane yield losses.
Recommendation The authors consider removal especially critical during cold, wet conditions.
