Two field experiments were carried out during 2013/2014 and 2014/2015 seasons at the Experimental Farm, Fac. Agric., Minia Univ. to investigate the effect of compost (0, 5, 7.5 and 10 ton/fed), mineral NPK, effective microorganisms (E.M.), vit. E, vit. B1, E.M. + vit. E. and E.M. + vit. B1 on the growth and productivity (fruits and essential oil) of coriander plants. The obtained data revealed that vegetative growth characters (plant height, stem diameter and herb dry weight/plant), yield components (number of umbels/plant, fruit yield/plant and /fed) and all studied oil production (oil %, oil yield/plant and /fed) were significantly increased due to the application of all levels of compost over those of control treatments. The maximum values were recorded at the high level of compost (10 ton/fed). Vegetative growth characters, fruit yield and essential oil productivity parameters were significantly augmented as a result of using the different six treatments. The most effective treatments in this concern were mineral NPK (full dose) followed by E.M. + vit. E without significant difference between such superior treatments. While, E.M. plus either vit. E or vit. B1 gave the highest essential oil %. Moreover, E.M. + vit. E followed by NPK (full dose) recorded the highest essential oil yield/plant and /fed. It could be recommended to supply Coriandrum sativum plants with compost at 10 ton/fed in combination with E.M. + vit. E. to alternative to compost (10 ton/fed) with mineral NPK (full dose) to ensure the safety, not only for human but also for the environment in which we live.
