An experiments were conducted during spring seasons of 2015 in medicinal and aromatic plant field follow of Agriculture College/ Basrah University to study the effect of date planting , plant density and spraying with sea algae extract kelpak on growth and yield parameters seeds and oil of basil plant ˝Ocimum basilicum var. Cinnamon L.˝ The aim of the experiments was focused on the effect of two date planting (15/2 and 1/3) three plant density 60, 90 and 120 plants.m - 2 and spraying with kelpak 0 and 2 ml.l - 1 . Sprying was done three time 20, 25, 30 days after propagating. Factorial experiments was analysis with Complete Block Design Randomized ( R.C.B.D) was used with three replication, Least Significant Differences Test (L.S.D) was used at probability of 0.05 with Genstat programs. The results could be summarized as follows : - 1. Effect date planting The first date (15/2) increased significantly in plant height, leaves number. plant - 1, leaves area, the number of inflorescences, seed yield.plant - 1 (2.37 gm), total seed yields (1850 kg), weight of 1000 seed (1.39 gm), percentage oil.seeds - 1 ( 9.80%), oil yields.plant - 1 (0.26 gm) and total oil yields (0.21 kg). While the second date increased significantly in the number of vegetative branches and the date of flowering. 2. Effect plant density The first density (60plants.m - 2) increased significantly in plant height, leaves number. plant - 1, leaves area, seed yield.plant - 1 (2.52 gm), oil yields.plant - 1 (0.208 gm), percentage oil.seeds - 1 ( 9.48%) and the specific weight of the oil, while the second date (90 plants.m - 1) increased significantly in weight of 1000 seed (1.37 gm), the refractive index and specific gravity of the oil pilot, while the third days increased significantly in date of flowering, total seed yields (2.329 kg) , total oil yields (0.21 kg).3. Effect biostimulative The sprying with 2 ml.l - 1 of sea algae extract (kelpak) caused significants increasing in plant height, the number of vegetative branches, leaves number.plant - 1, leaves area, the number of inflorescences, seed yield. Plant - 1 (2.58 gm), total seed yields (2020 Kg), percentage oil.seeds - 1 ( 10.96%), oil yield.plant - 1 (0.23 gm ) , total oil yields (0.19 Kg) and specific gravity of the Volatile , in addition to the amount of chlorophyll and total carbohydrates in the leaves, while the plants spraying with distilled water caused effect date flowering. The interactions between the studied factors caused significant increased effects in all characters’.4. The hits inhibitory concentrations of alcoholic extracts of leaves , flowers and seeds of basil plants against the two types of bacteria and fungi pathogenic to humans Test was done to the effectiveness of four concentrations which were50, 100, 150, 200 mg.ml - 1 of the methyl and ethyl alcoholic extracts for leaves, flowers and seeds of the basil plants in vitro on the two types of bacteria tested Escherichia coli and Staphylococcus aureus and two types of fungus Candida albican and Aspergillus niger by using filter paper disc diffusion method. The concentration 200 mg.ml - 1 of methyl alcoholic extracts for seeds was effective inhibition the growth of the bacteria Escherichia coli.and leaves and flower weer effective inhibition the growth of the bacteria Staphylococcus aureus and the leave extracts inhibitory effect against two fungi Candida albican and Aspergillus niger
