Abstract: The effects of EM bio-organic fertilizer on the agronomic traits,photosynthetic characteristics and yield of p otato microtuber were studied by using virus-free potato seedlings as experimental materials.The results showed that the survival rate and agronomic traits of potato seedlings were significantly improved by applying EM bio-organic fertilizer,and the yield of original seed was increased by 57.6% and 21.9% respectively by applying EM bio-organic fertilizer 1 and EM bio-organic fertilizer 2.

Key words: potato, EM bio-organic fertilizer, agronomic traits, photosynthetic characteristics, yield and quality
