Abstract:
A field experiment was conducted at the Agronomy field, Sher-e-Bangla
Agricultural University (SAU), during July to December, 2010 with a view to find
out allelopathic (eco-friendly concept) effect of different weed residues to control
weeds in Aman rice field. The experimental treatments included three T-aman rice
varieties viz. BRRI dhan46. Guti Swarna and Ranzit variety and five different
allelopathic materials viz.Control, Lantena camera, Goose weed, Ban sharisha and
Araich. Results showed that rice cultivars differed significantly in all growth and
yield contributing characters and Ranzit produced highest grain yield (5.35 t h&
5.
Among the treatments of allelopathic materials araich performed the best on
all the parameter studied and gave highest grain yield (5.44 th&). Interaction
showed significantly higher grain yield, was given by Ranzit with allelopathic
materials araich (6.51 t h&5. The higher grain yield was attributed to the
higher effective tillers hilF1(13.67). filled grains panicle'(256.00) and 1000-
grain weight (23.83g).
