Pine Cone as a Plant Growing Media in Strawberry
摘要
Growing media composition plays a vital role in soilless strawberry cultivation, affecting plant development, physiological responses, and production sustainability; therefore, evaluating alternative media from domestic sources is essential for both reducing import dependency and optimizing horticultural practices. This study evaluated the performance of pine cone (Pinus nigra) mixtures as growing media across multiple developmental and physiological parameters in strawberry cultivation. Seven different media treatments were tested: pine cone alone, cocopeat (control), peat–perlite (1:1), cocopeat–pine cone (1:1), peat–pine cone (1:1), peat–perlite–pine cone (1:1:1), and peat–vermiculite–pine cone (1:1:1). Based on our results, significant differences (p < 0.05) were observed between media types for all analyzed parameters. In general, pine cone mixtures demonstrated superior performance compared to pine cone alone, with peat–vermiculite–pine cone and peat–perlite–pine cone consistently showing enhanced plant development. The peat–vermiculite–pine cone mixture exhibited the highest leaf number per plant, primary root number, primary root length, and total chlorophyll content. Plant fresh and dry weights were maximized in peat–vermiculite–pine cone and peat–perlite–pine cone media, while root fresh weight peaked in peat–perlite medium. In contrast, pine cone alone showed consistently lower performance across most parameters, with developmental metrics declining compared to conventional media. Statistical analyses revealed distinct performance clustering, with pine cone mixtures achieving comparable results to the cocopeat control treatment. The results clearly distinguished high-performing mixture media from pine cone alone, demonstrating reduced effectiveness when used as a sole growing media. Overall, these findings demonstrate that pine cone mixtures offer viable alternatives to imported growing media in soilless strawberry cultivation. The results provide valuable insights for reducing production costs, utilizing forest byproducts, and developing sustainable cultivation strategies that support Turkey’s agricultural economy while maintaining optimal plant development.
