Abstract

This study aimed to evaluate the effect of organic growing media prepared from two types of compost (compost from leguminous crops “lens culinaris, Vicia faba, Cicer arietinum” and gramineous crops “Triticum aestivum, Hordeum vulgare,” and compost from wood carpentry waste and leguminous residues) on the germination of Laurus nobilis L. seeds and the growth of its seedlings. Four growing media were used: (T1) Control: nursery soil, and three media containing compost entirely or partially (T2) 50% leguminous and gramineous crop residue compost + 50% wood carpentry and leguminous residue compost, (T3) 50% leguminous and gramineous crop residue compost + 50% nursery soil, (T4) 50% wood carpentry and leguminous residue compost + 50% nursery soil. The results showed that treatment T2 was superior in all germination indicators, with an average germination percentage of 81.66% and an average germination speed of 20.8 days/seed, while the control treatment T1 recorded the lowest germination percentage of 41.66% and the slowest germination speed of 25.81 days/seed. The organic media also showed a clear improvement in morphological growth, with treatments T3 and T4 excelling in terms of shoot and root length. Treatment T2 achieved the highest average dry weight (1.74 g shoot, 2.44 g root) and the highest average number of leaves (24.3 leaves/plant).
