Salinity, particularly in the region of arid and semi-arid regions, is a significant limiting factor for crop development and yield. The purpose of this study is to determine how potassium humate and seaweed extract can reduce the harmful effects of salinity on green beans (Phaseolus vulgaris var. Pulista). In pots with sandy soil and saline water that had an EC of 500, 1000, and 1500 ppm, seeds were sown in March 2020 and 2021. The concentrations of seaweed extract and potassium humate used were 0.25 g/l and 0.5 g/l for the former and 1 g/l and 2 g/l for the latter. At 3, 5, 7, and 9 weeks after cultivation, application occurred. Data indicated that all elements of plant growth, including plant height, leaf count, fresh and dry weights, were better when plants were treated with seaweed extract and potassium humate as opposed to untreated plants. Yield parameters followed also the same trend. The tallest green bean plants were estimated from that plants treated by seaweed extract at concentration of 0.25 g/l followed by the treatments of 0.5 g/l seaweed extract also while, the treatment of potassium humate at concentration of 2 g/l came in the third rank. It was determined that potassium humste and seaweed extract were superior at reducing the effects of salinity on green bean plants.
