One of the main problems in the mass production of pepper transplant is the stickiness of seed coat to the cotyledony leaves that can lead to no emergence or having poor emergence of pepper seedlings.Therefore, in order to evaluate the effects of different soil compactions on emergence and early seedling growth of pepper, a greenhouse experiment was conducted in the Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, in 2011, using a completely randomized design with factorial fashion and four replications. The experimental treatment factors included different levels of soil compactions 0 (no compaction), 340.5,681.31and 1021.7pa and different pepper varieties (Olter, California Wonder, EM Bell, Anahiem and Iranian Falei). The results indicated that except the seed coat adherence to cotyledons leaves and the emergence percentage traits, the compaction treatments had a significant effect on (dry matter seedlings, height, leaf area, number of abnormal seedlings and mean emergence time.
