Data were analyzed by Analysis of Variance and then further tested by Duncans New Multiple Range Test (DNMRT) at the level of 5%. Visible indicator of treatment parameters plant height, plant dry weight, the maximum number of tillers, number of productive tillers, flag leaf length and age out panicles. The results showed ash sawdust giving 5 ton/ha to 10 ton/ha green manure legume species to increase vegetative growth of upland rice which give significantly different results for plant height, plant dry weight, number of tillers and the maximum length of the flag leaf.
