The effects of olive oil solid waste applications on the some physiological and morphological parameters of bean (Phaseolus vulgaris L.) and sunflower (Helianthus annuus L.) plants

Abstract

By considering the storage problems and the environmental harms caused by agricultural by-products and industrial wastes, researches on reusing these wastes are gaining great importance. In this study we investigated the olive oil solid waste applications on beans and sunflower growth. Olive oil solid waste (OSW) mixed with soil at the rates of 0, 3, 5 and 7 % by weight. Some physiological and morphological parameters such as chlorophyll contents, plant height, plant thickness etc. have been examined. As a result, it is determined that direct applications of olive solid waste negatively affect bean and sunflower growths.
