Abstract
An experiment was conducted to
evaluate the effect of inflorescence-top cuttings on the seed yield and yield
attributes of different mustard varieties (V1=Tori-7, V2=BARI
Sarisha-9 and V3=BARI Sarisha-15) under varying sowing times (S1=01
November, S2=15 November and S3=30 November) during
November, 2011 to February, 2012. Three inflorescence-top cutting were also
tested (C0=control, C1=early and C2=late, 80% maximum
siliqua have set, maximum siliqua have set). Seeds were
collected from the top, middle and bottom of the inflorescences. The individual
effect of the treatments was significant. Result
revealed that S2 showed the highest fresh siliqua weight at the
middle and bottom position of the inflorescence (0.29 and 0.33 g,
respectively), V3 showed the highest siliqua fresh weight (0.26,
0.35 and 0.38 g at the top, mid and bottom of the inflorescence respectively).
Likewise, C1 showed the highest siliqua fresh weight at the
corresponding stages (0.22, 0.30 and 0.32 g). Interaction effect of sowing time
and cutting time was found significant. Siliqua fresh weight at the top, mid
and bottom of the inflorescence of S1V3 and S2V1
(0.21-0.30, 0.29-0.38 and 0.33-0.41 g respectively), S2V3
(0.24-0.31, 0.36-0.39 and 0.33-0.41 g respectively), S3V3
(0.24-25, 0.29-0.41 and 0.35-0.44 g respectively) due to inflorescence cutting
at both C1 and C2, were found to be significantly higher
compared to other interaction treatments.
