Abstract
n order to investigate humic acid and complete fertilizer consuming time, on growth and yield characteristics of the Lepidum sativum L. an experiment was performed in a randomized complete design with three replications in Zabol of sistan and Baloochestan prorince, Iran, in year 2013-2014. The treatments include the spraing at 4 and 6 true leaves stayes organic fertilizer humic acid in 3 levels include: Without applying humic acid, spraing at 4 and 6 true leave stages.
