Abstract The broad bean (Vicia faba L.) originated in the Near East, and is cultivated around the world, however, its cultivation is affected by drought stress in several central growing regions of the globe. The present study was designed to determine the effect of biochar on bean plant growth, acquisition of nitrogen (N), phosphorus (P), and potassium (K) and on soil nutrient contents under drought and irrigated conditions. Pyrolysis char from maize (MBC) at 2 and 4% concentrations was used for pot experiments. The shoot and/or root biomass of bean grown in soil amended with 2 and 4% MBC under irrigated condition was increased. Furthermore, increased nodule numbers of bean grown at 4% MBC amendment was observed under both irrigated and drought conditions. P and K uptake of plants under drought conditions increased by 14% and 23% under 2% MBC amendment, and by 23% and 34% under 4% MBC amendment as compared to plants grown without biochar application, respectively. This study demonstrated beneficial effects of biochar produced from maize on growth and nutrient uptake of broad bean, by improving the nodule formation and soil nutritional contents in a sandy loam soil.

Introduction Biochar is considered as a tool in climate change mitigation and also used as a soil amendment for improving soil health (Barrow 2012; Ma et al. 2019a). The improvement of plant growth and health in response to biochar application was reported by many studies (Graber et al. 2010; Alburquerque et al. 2015; Egamberdieva et al. 2016, 2019; Ma et al. 2019b). Positive effects were related to improved soil * Dilfuza Egamberdieva [email protected] 1

cation exchange capacity, nutrient retention, microbial activity and soil water holding capacity (Kolton et al. 2011; Yu et al. 2013; Soudek et al. 2016). Biochar was also reportedly used for the formulation of bacterial inoculants and provided potential applications in crop production (Egamberdieva et al. 2017). Moreover, Elad et al. (2010) demonstrated an induced systemic resistance in plants to various fungal pathogens after the application of bioch
