The application of organic fertilizer materials (fish scrap, goat manure and olive pomace), application method (surface and trench) and biofertilizer (Nitrobein and Rhisobacterein) on growth and leaf mineral content of Manzanillo olive trees were investigated. Fish scrap fertilizer surpassed olive pomace and goat manure in enhancing tree growth and leaf mineral content Number of shoots per branch, shoot length, No. of leaves per shoot, leaf surface area and chlorophyll (a & b) were remarkably increased with fish scrap fertilizer applied in trenches and supported with Rhisobacterein. Also, leaf N, P, K, Ca, Mg, Fe, Mn and Zn content were enhanced with fish scrap fertilizer or olive pomace applied in trenches and providing with Rhizobacterein. In general, corporation of organic materials in trenches with biofertilizer resulted in synergistic effects on both growth and leaf nutrient content. |
