“…The RP, expressed as a function of the aerial portion of herbage mass theoretically available to grazing livestock, did not include residual herbage nor any change in plant mass occurring beneath the soil surface. Whole plant mass could reflect different photosynthate allocation patterns as a function of species, site and canopy management (Belesky, 2005a; Belesky et al. , 2008).…”

Pasture managers seek to balance leaf appearance with utilization to sustain sward productivity while meeting livestock nutritional needs. Achieving this in silvopasture must account for the influence of light and defoliation on tillering. We determined tiller production, as a function of light availability and clipping height, for two forage grasses adapted to cool, humid temperate conditions of the Appalachian region of the USA. Tiller production of cocksfoot (orchard grass) (Dactylis glomerata L.) and tall fescue (Festuca arundinacea Schreb.) was greatest in unshaded and least in shaded sites, irrespective of residual clipping height. Juvenile plants produced more than twice as many tillers as mature plants, with differences accentuated by site, reflecting a shift in reproductive and resource-use strategies. Trends in tiller production were as follows: cocksfoot > tall fescue; 10-cm > 5-cm residual clipping height; and unshaded > partially shaded > densely shaded sites. Tiller production reaches maximum earlier in the woodlot site, regardless of species or clipping height, than at the unshaded site. Plants at the wooded site extended leaves quickly, sustaining herbage production, but had less non-structural carbohydrate and fewer tillers. Cocksfoot, but not tall fescue, sustained leaf and tiller production in the shaded sites, suggesting that cocksfoot is suited for use in silvopasture in this region.

Tall fescue (Schedonorus arundinaceus [Schreb.] Dumort.) is genetically variable for many agronomic traits, so it might be possible to increase its persistence and productivity in shaded agroforestry applications. The objective of this research was to identify high yielding, shade-tolerant genotypes. Seed was obtained from eight families: seven plant introductions of European origin: 234718, 234720, 234882, 234884, 235018, 235019, 235036, and one cultivar (Kentucky 31). Two sequential experiments were conducted to select genotypes for dry mass yield during April-September. Experiment 1 included 30 genotypes of each of the eight families randomly assigned to each of two microenvironments: artificially shaded with fabric and unshaded. Maximum and minimum yields were 93.9 and 47.1 g family -1 for Kentucky 31 and 235036, respectively. After 1 year in Experiment 1, there were more survivors in the unshaded than shaded environment (0.40 and 0.09, respectively), ranging from 0 to 0.56 (235036 and Kentucky 31, respectively). Forty robust genotypes from four families (234718, 234720, 235019, and Kentucky 31) were selected from shaded and unshaded microenvironments of Experiment 1, clonally propagated, and evaluated in pots for 2 year in Experiment 2. Shade-selected Kentucky 31 yielded more (31.0 g plant -1 ) in shade than other shadeselected families (25.2-25.8 g plant -1 ). Eleven genotypes in the top quartile (yield C33.0 g plant -1 ) were selected for further testing. All genotypes were endophyte (Neotyphodium coenophialum MorganJones and Gams)-infected. Further testing is needed to measure heritability of yield in shaded, water-deficit conditions of a tree understory.
