<strong>of</strong> both <strong>of</strong> the center rou/s <strong>of</strong> each p1ût was hand
harvested and threshed in a Vogel Plot Thresher,
except at Carman, 19?6 where whole plots were
f iel-d harvested with a "lüGE" pl-ot combine.
(J) Number <strong>of</strong> spikes per unit aï'ea - the number <strong>of</strong>
fertile heads was counted in a random one meter
section <strong>of</strong> one <strong>of</strong> the two center rows <strong>of</strong> each
plot. (Íhis is equivalent to a 0.11 square rneter
area " )
(4) Kernels per spike
(5) 2oo Kernet weight
(6) legree <strong>of</strong> lodging - recorded as a value on a scale
<strong>of</strong> one to nine, with one being no lodging. Taken
ín 1975 only.
(7) fest weight - recorded as tg./trt. and determined
by standard procedure s.
(B) oays to Heading
(9) nays to maturity
(lO) Post-anthesis period
( 11) Percent barley nitrogen
(1e) ,tlpfra-amylase 1eve1s - taken in L9? 5 only
(13) Saecharifying activity - taken in IgZ5 onlry
(t4) Sotu¡te amino-nitrogen - taken in 1975 onl.y
Analyses <strong>of</strong> variance were computed for each character
at each location to deternine: (1) if differences existed
between treatments and (2) if any nitrogen fertilizer by
genotype interactions had occurred r
