Abstract:
A field experiment was conducted at the experimental farm of Sher-e-Bangla
Agricultural University (SAU), Dhaka, during the period from March 2007 to
June 2007 to study the in uluence of different leaf clipping and fertilizer doses
on growth and yield of mungbcan. The trial comprised four treatments on
leaf
clipping (No removal, removal of new leaves developed after first flowering,
removal of subtending leaves beneath the inflorescences and removal of empty
leaves), and(.three treatments on fertilizer doses per hector (10 kg N + 20 kg
P205 + 15 kg K20. 20 kg N + 40 kg P205
± 30 kg K20 and 30 kg N + 60 kg
13205+ 45 kg K2O).'ResuIts showed that the leaf clipping treatments had
significant effect on growth and yield parameters. Removal of empty leaves
resulted in the highest plant height, dry matters from leaf. stem, root and
infioreseenees with yield and all the yield attributes as well1.flie fertilizer doses
also affected the studied parameter significantly. The highest values on most of
the growth and yield parameters were obtained with 20 kg N
4-
40 kg P205
kg K
20Tha In case of interaction of treatments, removal of empty leaves
coupled with 20 kg N + 40 kg P205
± 30 kg K2
0 (ha) showed significantly
highest values on stem dry weight (10.69
plant), root dry weight (2.49
g/plant), stover weight (2.10 g/plant), pod length (12.98 cm), number of
seeds/pod (12.31), 1000 seed weight (40.67 g).(grain yield (1.12 tiha) and
harvest index (34.78 %) The higher yield was attributed to the absence of
leaves having no infloresc-enee on their axils and also to the balanced
fertilization.
