Therefore, photosynthesis decreases in shaded leaves and loss of asimilant comes true with the increase of respiration. This study was planned to determine leaf area change, yield and properties effective on yield of broad bean sowed in different densities. Experiment was conducted in Samsun conditions for two years with Filiz-99 broad bean variety and at six different sowing densities (25x15, 25x25, 50x15, 50x25, 75x15, 75x25) according to randomized completed block design with three replications. Datas were combined over the years and variance analysis was done. According to variance analysis result, those were determined that row spacing affected pod number, stem diameter, a hundred seed weight, seed yield and leaf area; intrarow distances affected plant height, first pod height and seed yield; years affected plant height, branches number, pod number, stem diameter, pod length, a hundred seed weight, seed yield and leaflet number, statistically. As a result of correlation analysis made separately for different row spacing distances, a positive correlation between seed yield and pod number, stem diameter, pod height and a hundred seed weight was seen at three row spacing. When there was no relationship between leaf area and other features at 25 cm row spacing, a positive correlation was determined between leaf area and stem diameter at 50 cm row spacing and also for 75 cm row spacing leaf area had a positive correlation with leaflet number and a negative correlation with seed number in the pod.
