(11 cards)
1
Q
what is the most widely seeded pasture grass on canadian prairies

A

3
Q
description of meadow brome
A
- many basal leaves (narrow and pubescent)
- short rhizome (kind of looks like bunchgrass)
- high level of veg tillers (rapid regrowth)
4
Q
adaptation of meadow bromegrass
A
- not as drought tolerant as smooth brome
- can grow on all soil textures
- winter hardy
5
Q
why is meadow brome good for pasture use
A
- fast regrowth (grow faster under grazing than smooth brome)
- good seasonal distribution of growth
- extended fall grazing season, as leaves stay green later in fall
6
Q
hay production of meadow brome
A
- lower yielding than smooth brome
- basal leaves lodge (make difficulty in cutting and windrowing)
- often mixed with alfalfa
7
Q
what is hybrid brome grass the offspring of
A
meadow x smooth bromegrass
8
Q
hybrid bromegrass description
A
- upright growth with some basal leaves
- short rhizomes (minimal creeping)
- pubescent leaves and stems
9
Q
what is hybrid grass used for
A
dual-purpose grass
- high yielding for hay
- fast regrowth for pasture
10

A
f, hybrid grass grows faster
11
