| Abstract | ||||
| Compost produced from shrimp shells mixed with other botanical wastes as organic soil amendment was examined in a pot experiment for a possible improvement in growth of eggplant in marginal sandy soil. Shrimp shells with rice straw, banana peels, pomegranate peels were recycled in a compost production process and used with Azotobacter chrococcum as organic and bio-fertilizer for eggplants in a greenhouse experiment. The obtained results referred to a positive growth promoting effect of the compost product and/or the bacterial inoculum on eggplants. Compost application and bacterial inoculation increased eggplant dry and fresh weight as well as improved the nutritional values of grain, i.e., total carbohydrates, total phenol and total chlorophyll. In addition, soil organic matter was increased in pots received the combined treatment with compost and the bacterial inoculum. Slight changes were recorded in soil pH and EC as a result of organic or biofertilizer application. The examined compost product from shrimp shells might be used with the bacterial inoculum as potential soil amendments in organic farming program. | ||||
