A study was undertaken to observe the effect of shade of the trees on the yield of paddy and green straw of two different rice varieties, local variety, Kazol Shail and high yielding variety, BRRI-32. The yields of paddy of Kazol Shail in the shaded and un-shaded area were 0.76 and 2.21 t per ha, respectively. The yields of paddy of BRRI-32 in the shaded and un-shaded area were 1.83 and 3.63 t per ha, respectively. The yields of green straw of Kazol Shail in the shaded and un-shaded area were 4.89 and 10.11 t per ha, respectively. The yields of green straw of BRRI-32 in the shaded and un-shaded area were 7.61 and 14.17 t per ha, respectively. The results revealed that the yield of paddy of Kazol Shail and BRRI-32 in the un-shaded area are 190.79% and 98.36% higher than in the shaded area, respectively. The yield of green straw of Kazol Shail and BRRI-32 in the un-shaded area are 106.75% and 86.20% higher than in the shaded area, respectively.
