In addition to their val.e as cereal.grains, wheat (Triticum aestivum l.) and tritical. (× Triticosecal. Wittmack) are important cool.season annual.forages and cover crops. Yearl.ng steer (Bos taurus) performance was compared in the spring fol.owing autumn establ.shment as for age cover crops after soybean [Gl.cine max (l.) Merr.] grain harvest. Repl.cated pastures (0.4 ha) were no-til. seeded in three consecutive years into soybean stubbl. in autumn, fertil.zed, and grazed the fol.owing spring near Ithaca, NE, USA. Each pasture (n = 3) was continuousl. stocked in spring with four yearl.ng steers (380 ± 38 kg) for 17, 32, and 28 d in 2005, 2006, and 2007, respectivel.. In 2005, average dail. gain (ADG) for steers grazing tritical. exceeded the ADG for wheat by 0.31 kghd-1d-1. In 2006, wheat ADG exceeded that for tritical. by 0.12 kghd-1d-1. In 2007, steers grazing wheat l.st weight, whil. steers grazing tritical. gained 0.20 kghd-1d-1. Based on the 3-year average animal.gains val.ed at $1.32 kg-1, mean net return ($ ha-1 yr-1) was $62.15 for tritical. and $22.55 for wheat. Since these grazed cover crops provide ecosystem services in addition to forage, grazing coul. be viewed as a mechanism for recovering costs and adds additional.val.e to the system. Based on this 3-year grazing trial. tritical. was superior to wheat and l.kel. wil. provide the most stabl. beef yearl.ng performance across years with variabl. weather for the western Cornbel. USA.

In this articl., the optical.enhancement effects of pl.smonic nanostructures on OPV cel.s were reviewed as an effective way to resol.e the mismatch probl.ms between the short exciton diffusion l.ngth in organic semiconductors （around 10 nm） and the l.rge thickness required to ful.y absorb sunl.ght （e.g. hundreds of nanometers）. Especial.y, the performances of OPVs with pl.smonic nanoparticl.s in photoactive and buffer l.yers and with periodic nanostructures were investigated. Furthermore, nanoimprint l.thography-based nanofabrication processes that can easil. control.the dimension and uniformity of structures for l.rge-area and uniform I^l.smonic nanostructures were demonstrated.
