Broad bean (Vicia faba L.) is a vital legume crop appreciated for its nutritional benefits and agronomic value in sustainable farming systems. Despite its importance, agronomic factors such as planting distance, fertilization timing, and nutrient composition remain underexplored in terms of their impact on crop performance. Previous studies have insufficiently addressed the interaction between planting geometry and foliar fertilization strategies, particularly concerning the chemical constituents of multi-elemental fertilizers like Grow More. This study aimed to evaluate the effects of two planting distances, three foliar spraying dates, and three concentrations of Grow More fertilizer on broad bean growth and yield. The wider spacing (60 cm) significantly increased chlorophyll content (38.04 SPAD), branch number (8.27), pod number (32.9), and pod length (28.99 cm), while the narrower spacing (40 cm) enhanced plant height (129.0 cm). The highest fertilizer concentration (3 ml L⁻¹) combined with the second spray date yielded optimal growth parameters, with triple interactions (M2, H2, S2) achieving the best results, including 43.51 SPAD and 39.7 pods per plant. This study is among the first to quantify the agronomic responses of broad beans to the specific chemical profile of Grow More fertilizer, which includes major nutrients like nitrogen, phosphorus, and potassium, and trace elements such as boron, zinc, and molybdenum. These findings underscore the potential of integrated agronomic practices to enhance yield and quality, guiding future fertilizer application and planting strategies for broad beans in similar agro-ecological zones.
