Forages, Clipping times, Wheat, Barley, Triticale, Forage quality, Introduction


The present study was conducted in Sulaimani Region at two different locations,
Qlyasan and Kanipanka during the winter season of 2010-2011, to determine the effect
of different clipping times{clipping at 80 days after sowing (1st clipping time), clipping
at 90 days after sowing (2ndclipping time), clipping at 100 days after sowing (3dclipping
time), and clipping at 110 days after sowing (4th clipping time) as well as control (no
clipping)}on forage quality of three cereal crops (wheat, barley and triticale) at Qlyasan
location and the following day similarity at Kanipanka location. The design was split
plot within factorial experiment, the cereal crops were implemented in the main plots and
arranged with complete randomized design (CRBD) and replicated three times, where
the clipping times were implemented in sub plots. Means comparison were carried out
using least significant difference test (LSD) at 0.05 significant levels.
The results of the present study as the average of both locations showed that the fourth
clipping time exceeded the other clipping times in the characters: Acid Detergent Fiber
(ADF%), Acid Detergent Lignin (ADL%), Neutral Detergent Fiber (NDF%), fiber%,
starch% and Mg% with the values of 28.222%, 5.645%, 39.194% , 14.282%, 8.223%
and 0.080% respectively, while the first clipping time exhibited maximum values of
14.561% , 24.992%, 81.138%, 0.545% , 4.408%, 0.583% and 3.734% for the characters
Ash%, protein%, DP%, Ca%, K%, P% and fat% respectively.
According to the results of this study we concluded that protein and digestible protein
were differed significantly among species, where barley showed its superiority in these
characters and most quality traits compared to wheat and triticale, and The quality was
diminished as maturity increased, the nutrient composition and forage quality of small
grain plants change significantly as the plants develop; therefore, the earlier cutting dates
are recommended to achieve this purpose.
