The aim of the study was to investigate Q. castaneifolia seedlings growth and development at different irrigation treatments. For this purpose a trial under completely randomized design using four irrigation periods [0 (control or rainfed), 2, 4 and 6 days] was conducted on a sandy soil at coastal part of the Caspian region of Iran (Noor city). The results at the end of first growing season revealed that the seedlings under rainfed condition obtained least survival, collar diameter, leaf area, length and number of nodes at 2nd growth flush. However, there was not significance differences among treatments in root length, stem length, length and number of nodes at first growth flush. All characteristics measured did not significantly differ at three irrigation regimes (2, 4 and 6 days). If seedling production of Q. castaneifolia with high growth is an aim, it is suggested to irrigate the seedlings at 6-day period (instead of 2- and 4-day periods) and to maintain them under shade.
