Productivity of Crimson and Arrowleaf Clovers Grown in a Coastal Bermudagrass Sod¹

W. E. Knight Agronomy Journal 1970. doi:10.2134/agronj1970.00021962006200060027x

Other claims from this paper (13)

Observation Clover species did not differ significantly in seedling counts.
Intervention effect Self-reseeding stands produced earlier growth.
Observation Total production did not differ significantly by seeding method.
Observation Crimson clover averaged 33% more forage than arrowleaf.
Mechanism Arrowleaf had lower yields due to poor recovery and regrowth during drought.
Intervention effect Grass after clover produced 18% more forage than fertilized grass without clover.
Observation Total grass yield did not significantly differ after crimson versus arrowleaf clover.
Observation The first grass harvest after arrowleaf was reduced.
Mechanism Greater competition from arrowleaf than crimson clover caused the first-harvest reduction.
Intervention effect Clover followed by Coastal bermudagrass produced 47% more total forage than fertilized grass without clover.
Observation The crimson clover–bermudagrass sequence produced the highest total forage.
Observation Crimson clover contributed 22% to total yield.
Recommendation The authors recommend winter annual clovers to supply part of summer grass nitrogen needs.

Other claims from this paper (8)

Intervention effect 2,4DB at 0.56 kg/ha was consistently selective for arrowleaf clover.
Intervention effect 2,4DB at 0.56 kg/ha adequately controlled broadleaf weeds, including curly dock seed stalk formation.
Intervention effect MCPA at 0.56 kg/ha controlled broadleaf weeds.
Intervention effect MCPA at 0.56 kg/ha was not consistently selective for arrowleaf clover.
Intervention effect 2,4-D at 0.56 kg/ha controlled broadleaf weeds.
Intervention effect 2,4-D at 0.56 kg/ha significantly reduced arrowleaf clover forage production.
Intervention effect 2,4-D reduced arrowleaf clover seed production less than forage production, with significance at one location only.
Intervention effect The 2,4D and banvel combination severely damaged arrowleaf clover.

Other claims from this paper (8)

Intervention effect Defoliation and P, K and Ca fertility increased arrowleaf top growth.
Intervention effect Defoliation and P, K and Ca fertility increased arrowleaf tiller number.
Intervention effect Defoliation and P, K and Ca fertility increased arrowleaf nodule mass.

Observation Arrowleaf alone had fertilizer N equivalence of 50 kg N ha −1.
Observation Combined arrowleaf and crimson clover had fertilizer N equivalence of 89 kg N ha− 1.
Observation Residual nitrogen fixed by arrowleaf alone raised subsequent rye yield equivalence to 111 kg N ha− 1.
Observation Residual nitrogen from combined arrowleaf and crimson clovers raised subsequent rye yield equivalence to 121 kg N ha− 1.
