Abstract: The experiment is carried under greenhouse conditions of Resource and Environment Institute of Hebei Academy of Agriculture and Forestry Sciences. Providing required nutrients of N, P, K and other essential nutrients thisstudy aims to determine the effects of different levels of sulfur on the herbage yield output, biological characterist ics andspeed of regeneration of alfalfa. Research results show that S2 has best effects on plant height, leaf diameter, herbage yieldoutput and it is economically efficient in increasing production from first stubble branching to first stubble floweringstages,while S3 has best effects on the regeneration speed.The plant stem leaf ratio decreases as sulfur nutrit ion level increases. Analysis of each biological character shows that S2 is best sulfur treatment for alfalfa in this study.

Key words: Alfalfa, Sulfur nutrition, Biology character, Regeneration speed
