This experiment was carried out at the Agricultural Experiment and Research
Center of Cairo University, Giza. Egypt in 2001 and 2002 seasons. The aim of this
investigation was to determine the suitable number of cuttings and stubble height of
sewpea to get the highest and best forage and seed yield of cowpea. Four cutting
treatments were: one cut at seed harvesting, two cuts, three cuts and four cuts. Three
stubble heights were 10, 20 and 30 cm. Taking three cuts significantly surpassed
other cutting number treatments in seasonal fresh fomge yield in the first season by
34.5, 19.8 and 22.3 “lo and in the second season by 23.5. 2.4 and 2.4 % for one cut at
seed harvesting, two outs and tour cuts, respectively. Leaving 30 cm as a stubble
height significantly surpassed other stubble heights in seasonal fresh and dry forage
yields of cowpea in the first season. This superiority of seasonal fresh forage yield
was 21.5 and 14.4 % in 2001 and the superiority of seasonal dry forage of cowpea
was 18.8 and 12.5 "/c. for 10 and 20 cm. in the respective Order. Taking three cuts with
stubble height at 30 cm significantly gave the highest seasonal fresh and dry yields in
the first season. Whereas. in the second season. taking four cuts with the same
stubble height (30 cm) significantly recorded the highest seasonal fresh and dry
yields. Taking three cuts gave the highest seasonal protein yield in the first season.
whereas. in the second season taking four cuts significantly gave the highest
seasonal protein yield. increasing stubble height from 10 to 30 cm increased seasonal
protein yield in the first season, but in the second season this increase in seasonal
protein yield stopped at 20 cm. The highest pod yield was significantly obtained by
taking one cut at seed harvesting in both seaSons. increasing stubble height from 10
to 30 cm gradually increased pod yield with insignificant differences in both seasons.
Taking one cut at seed harvesting surpassed the other cutting numbers in seed yield
in both seasons. This superiority of seed yield was 64.9. 21.3 and 44.3 % in 2001 and
61.8. 92.7 and 92.3 % in 2002 for two cuts. three cuts and four cuts in the respective
order. increasing stubble height from 10 to 30 cm gradually increased seed yield
without significant differences in both seasons.
