ABSTRACT
The reaction of several bread wheat cultivars (Triticum aestivum L.) and spermine under new recovered sandy soil conditions was examined during the winters of 2021–22 and 2022–23 at Al-Dakhla –New Valley, Egypt. The experiment included 40 treatments, which were combinations of wheat cultivars Misr-1, Misr-2, Misr-3, Sakha-94, Sakha-1001, Sids14, Gemmeiza12 and Shandaweel1 and levels of spermine (0, 2, 4, 6 and 8 ml/ha^-1). The findings showed notable variations in all examined features between wheat cultivars. The Sakha-94 cultivar greatly outperformed other cultivars in both seasons for grain yield/ha.  Wheat cultivar Misr-3 outperformed the others in terms of plant height and spike length. Sakha-1001 produced the No. of spike m-2. Application of either spermine 8 ml greatly improved all examined properties. The Sakha-94 wheat cultivar achieved the maximum grain yield (4190 kg/ha^-1 in the first season and 4295 kg/ha^-1 in the second one). However, this study recommends the importance of the Sakha-94 wheat cultivar with the application of Spermine 8 ml under Al-Dakhla –New Valley, conditions.
