This paper used peat and coconut chaff as control to study the seedling effects of cassava stalk substrate on tomato, cucumber,luffa, eggplant, wax gourd and watermelon seedling in order to provide basis of cassava stalk substrate on seedling.The seedling resultsshowed that: (1)Cassava stalk substrate on tomato seedling, its germination percentage, plant height, stem diameter and true leaves numberwere as well as the seedling effects of peat, and the seedling effects of cassava stalk substrate(Ф<2 mm) were not so well as the effects of peatbut were better than the seedling effects of coconut chaff. Cassava stalk substrate on cucumber seedling, its germination percentage, plantheight, stem diameter and true leaves number were as well as the seedling effects of peat and coconut chaff. The tomato and cucumberseedling effects of cassava stalk substrate(Ф<2 mm) were not so well as the effects of primary cassava stalk substrate.(2)The seedling effectsof cassava stalk substrate and cassava stalk substrate sieved by 2 mm sieve on luffa, wax gourd and watermelon were not so well as the effectsof peat and coconut chaff but the effects on eggplant were better than the effects of coconut chaff. On the whole, maturity cassava stalk couldbe used on tomato, cucumber and eggplant seedling, but not suitable for luffa,wax gourd and watermelon seedling.
