Abstract
The aim of this research is to study the effect of foliar spraying with mineral ,fertilizers , seaweed and hemichemic acid on the development and growth of hazelnut seedlings, especially on the, length diameter, leave number and the leave area. The results showed that the soluble fertilizers exceeded the all treatments conceding the seedling length, which was (28.27cm) and leaves , the diameter arrived to (23.60 leaves) , the diameter (11.95m.m) and root length arrived to (22.26cm) and leave area (7.105cm2) , while the concentration of 10g\l was exceeded the other concentration conceding the length of seedling which was (22.88cm) and leaves number (19.50) , diameter (17.32m.m). When studying the interaction the result showed that the soluble fertilizers exceeded at the conceding the seedling length, which was (35.84cm) and the treatment of hemichemic acid at concentration of 15g\l conceding leaves number (31 leaf) , leaf area (9.53cm2) and the treatment of seaweed of concentration 10g\l conceding the seedling diameter which was (17.32m.m).
