With its porous structure, high water storage capacity and high levels of macro- and micronutrients, vermicompost can play an effective role in plant growth and development. The purpose of this research is to reduce the use of inorganic fertilizers in large agricultural holdings where dry beans are grown to protect soil and crop health, and to popularize the use of cow and worm manure. The research was carried out from April to August of 2020 and 2021, in the Faculty of Agriculture of Dicle University in the southeastern Anatolia of Turkey, and the aim was to evaluate the effect of separate and combined applications of cow manure (2.5, 5.0 and 10 t ha-1) and liquid vermicompost (recommended 50% and 100%) on the growth, yield and yield components of dry bean (Phaseolus vulgaris L.). The experiment was laid out in the randomized complete block design with three iterations. The soil was treated with vermicompost as foliar spray at the crop’s flowering stage and with cow manure - during sowing.  Plant samples for growth parameters were collected every 20 days starting from 20 days after emergence (DAE) until maturity, and plots were harvested for yield and yield components. Differences among the applications were significant for growth, yield, and yield components. 10 t ha-1 of cow manure + 100% recommended dose of vermicompost produced high levels of vegetative parts, such as leaves and stems until 80 DAE, but the highest seed yield (14.2 g plant-1) and yield components were achieved in the 5 t ha-1 of cow manure + 100% recommended dose of vermicompost combination. Even a separate vermicompost application increased in the vegetative parts and yield components of bean plants compared to control.
