A field experiment was conducted from 1989 to 1991 on a Fox loamy sand soil to study the effects of harvest date on selected agronomic, physical and chemical characteristics of peppermint (Mentha piperita L.). Plant biomass and essential oil yields increased throughout the season to a maximum in very late August to early September. Menthol, neomenthol, and menthyl acetate concentrations increased in the essential oil with plant development. The amount of menthone and isomenthone was highest in immature plants. The concentrations of menthofuran and pulegone in the essential oil corresponded to the amount of flower bloom in the peppermint. Changes during the season in the concentrations of piperitone, terpinene-4-ol, α-terpineol, 1,8-cineole, limonene, γ-terpinene, terpinolene, α-terpinene, α-pinene, β-pinene, 3-octanol, β-myrcene, Linalool, sabinene, caryophyllene and Germacrene-D were typically quite small. In general, these preliminary results indicate that peppermint can be grown successfully on the coarse-textured soils of Ontario.

Three spring barley (Hordeum vulgare L.) and four annual ryegrass (Lolium multiflorum Lam.) types were intercropped to evaluate the potential yield and quality of forage which can be produced under irrigation in southern interior B.C. All treatments were intercrops; when barley cultivar effects are described they are averaged over the ryegrasses and vice versa. Barley cultivars differed in grain maturity. Ryegrass cultivars included diploid and tertraploid Italian and Westerwolds types. Intercrops including late grain maturing barley cultivars (Samson and Virden) increased the yield of the first silage cut (both by 25% over 2 yr) compared to Diamond, a medium-maturing cultivar adapted to the area. Intercrops containing the semi-dwarf barley, Samson, produced more digestible forage including higher in vitro digestible dry matter (IVDDM) and lower ADF and lignin. Annual ryegrass yield in the first cut intercropped with Samson was almost twice that with either Diamond or Virden, showing that Samson barley is less competitive. Second-cut yield (ryegrass regrowth) was greater for tetraploid than diploid annual ryegrasses. Yields of fall pasture (cuts 3 and 4) were similar among ryegrass cultivars. Cuts 2 and 3 (ryegrass only) of Italian ryegrasses had superior quality (higher IVDDM and protein; and lower ADF, lignin, and NDF) to Westerwolds ryegrassses, but all cultivars had similar quality in the late fall (Cut 4). It was concluded that a range of barley and annual ryegrass cultivars can be successfully intercropped to produce forage in south central B.C.Key words: Intercropping, barley annual ryegrass, forage yield and quality
