1. Bahiagrass Canopy Size, Soil Water, and Establishment of Aeschynomene

Author:
R. S. Kalmbacher; F. G. Martin; L. C. Hammond; K. J. Boote; P. Mislevy
Source:
Agronomy journal 1993 v.85 no.3 pp. 535-540
ISSN:
0002-1962
Subject:
Aeschynomene americana; pasture plants; Paspalum notatum; sward; canopy; soil water potential; soil water content; seedlings; evapotranspiration; rain; Florida
Abstract:
... Aeschynomene americana L. is a tropical pasture legume, and in Florida, where it is usually grown with bahiagrass (Paspalum notatum Flügge), there are about 5000 ha. Limited soil water is a primary reason for stand failure of this annual. Soil water in three bahiagrass canopy sizes: small (2.2 leaf area index [LAI]), medium (4.5 LAI) and large (7.7 LAI) was measured at seeding and related to aesch ...

Agronomy journal 1993 v.85 no.3 pp. 576-583
ISSN:

Subject:
Glycine max; double cropping; Triticum aestivum; soil water content; crop yield; seeds; rain; dry environmental conditions; water stress; drought; sowing date; Kentucky
Abstract:
... Double-crop soybean [Glycine max (L.) Merr.] comprises nearly one-third of the total soybean hectarage in the southeasteirn USA. This study was initiated to investigate the water relations of soybean following winter wheat [Triticum aestivum (L.) emend. Thcll], with emphasis on the role of stored soil water. A treatment scheme was devised in which wheat was killed at heading, mid-grain fill, and m ...

Agronomy journal 1993 v.85 no.3 pp. 541-545
ISSN:

Subject:
interspecific variation; cultivars; mathematical models; forage crops; Panicum coloratum; application rate; soil water content; Cynodon dactylon; arid zones; dry matter accumulation; crop yield; rain; growth models; Eragrostis curvula; Cenchrus ciliaris; nitrogen fertilizers; Texas
Abstract:
... Models provide a quantitative means to evaluate yield response of forage grasses to applied N and water availability. The objective of this analysis was to estimate model parameters (A, b, c) for bermu. dagrasses and bunchgrasses grown at the same location and during the same time period. The logistic equation was used to relate annual dry matter production to applied N for three bermudagrasses [C ...
