Abstract: To find out shading effect of some selected tree species and different orientations on the yield and yield attributes of rice cv BR11 in agro forestry system an experiment was laid out in two factorial, Randomized Complete Block Design with three replications.Rice was grown in different orientations around the tree of Albida, Akashmoni and Jhau (North, South, East and West orientations), as the orientations were made 1 m apart from the tree base.The effect of tree-rice association was found significant on plant height, effective tillers hill -1 , non-effective tillers hill -1 , effective grains panicle -1 , sterile spikelets panicle -1 , total grain (t ha -1 ) and straw yield (t ha -1 ).It was recorded that out of the three tree-rice association, the highest yield (4.88 t ha -1 ) was found under Albida and the lowest yield (4.70 t ha -1 ) was found under Akashmoni that was statistically similar with Jhau.The highest (7.10 t ha -1 ) and lowest (6.80 t ha -1 ) straw yield were found under Albida and Akashmoni.The highest plant height (105.75 cm), effective tillers hill -1 (11.85), non-effective tillers hill -1 (1.91), effective grains panicle -1 (140.65), and sterile spikelet panicle -1 (29.88) were found under the Albida.Regarding different orientations from the tree base, the plant height, effective tillers hill -1 , noneffective tillers hill -1 , effective grains panicle -1 and grain yield (t ha -1 ) of rice were significant.The highest grain yield (4.86 t ha -1 ) of rice was obtained at the north orientation and the lowest grain yield (4.60 t ha -1 ) of rice was obtained at the west orientation, while significantly highest grain yield (5.00 t ha -1 ) was found in control.All parameters produced the highest performance in open field compared to tree-rice association in respect of orientation.
