The effect of olive pomace and seaweed extract on the growth of pepper seedling

In recent years, environmental pollution problems have increased due to organic wastes. The use of wastes as fertilizer plays an important role in reducing and improving the physical, chemical biological properties soil. This study was carried out determine effect unprocessed olive pomace (OP) which is a by-product oil industry seaweed (SW) on growth pepper seedlings. study, 4 different ratios (5% OP + 95% peat, 10% 90% 15% 85% peat 20% 80% V:V) SW extract doses ( 0% 0.5%, 1% 2% ) were used. parameters such plant height, stem diameter, leaf area, fresh dry weights, chlorophyll index investigated. According results applications significantly decreased number, weight, root content, stem-root ratio total while length increased. On other hand, had no but partially imporoved zero application.
