Two field experi»zents were conducted at Moshtohor to study theeffect of hoeing treatments on yield, yield components, oil and protein contents in
seeds of some soybean varieties during 1992 and 1993 summer seasons. .
Results showed that Crawford cultivar had the tallest plant, while
Pershing cultivar had the shortest plant. Pershing cultivar gave the highest values
of number of branches/plant, number ofpods/plant, seed weight/plant, seed yield
(kg)/feddan, protein yield/feddan and oil yield/feddan and gave the lowest values
of 100-seed weight than the other cultivلrs in the combined analysis over two
seasons. On the other hand, Cutler 71 had the minimum number of branches and
pods per plant. Also Essex cultivar gave the lowest VGIUCS of pod weight and seed
weight per plant. There were insignijicant dfferenceڑ between cultivars for oil
and protein percentage in seeds of soybean.
. Number. of pods/plant, pod weight/plant, seed weight/plant, 100-seed
weight, seed yield/fed., protein yield/fed and oil yield/fed. were sign ijى cant/v
increased as affected by hoeing treatments when compared with unweeded
treatment in the combined analysis over two seasons. Whereas, unweed treatment
gave the tallest plants. On the other hand, number of branches/plant, protein %
and oil % were signijىcantly affected ‘by hoeing treatments. The increases as
percèntage in seed yield/feddan were 8.10%, 7.3%, 10.2% and 16.2% for hand
hoeing over all season, one hoeing at 3 weeks or at 5 weeks after planting, or two
hoeing at 3 and 5 weeks after planting, respectively when compared to unweeded
treatments. |
