Abstract:Sweet pecan (Carya illinoensis [Wangenh.] K. Koch) seedlings were subjected to six methods of establishment at two locations in southern Louisiana. Two of the methods involved containerization and four involved top-clip-ping of bare-root seedlings. On a poor silty clay bottomland site, bare-root seedlings clipped to a 10-in. top and those left unclipped were the tallest after 3 years, averaging 22.2 in. and 20.6 in. in height, respectively. Third-year survival of seedlings clipped to a 10-in. top was 94% as compared to 85% for unclipped seedlings. Therefore, pecan seedlings planted on poor bottomland sites should be bare-root stock and may be clipped to a 10-in. top or left unclipped. On a good silt loam minor streambottom site, seedlings grown in containers in a greenhouse for 1 year prior to planting were the tallest, averaging 37.0 in. in height, 7.4 in. taller than unclipped bare-root seedlings. Third-year survival was greater than 91% for five of the six methods. Ideally, containerized seedlings should be used to artificially regenerate pecan on good minor streambottom sites. However, top-clipping of bare-root seedlings at planting time is not detrimental and results in good survival and growth for the first 3 years. South J. Appl. For. 11(1):56-59.
