Abstract

To investigate the effect of bed width on yield and yield components of beans, an experiment was conducted using a split-plot arrangement in a randomized complete block design with three replications at the Khomein Bean Research Station during 2022–2023. The main plot treatments were: planting on beds with a width of 80 cm (P1), planting on beds with a width of 30 cm (P2), and flat planting (P3). The subplots consisted of three bean varieties: Line 492 (Type I, upright growth habit, V1), Kusha variety (Type II, semi-creeping, V2), and Saleh variety (Type III, creeping, V3). Measured variables included machine field working capacity (ha/h), biological and dry grain yield (kg/ha), 100-seed weight (g), and harvest index. The results showed that the highest grain yields were obtained with bed widths of 30 cm and 80 cm, yielding 2349 kg/ha and 2261 kg/ha, respectively. The lowest yield was recorded in the flat planting method (conventional treatment), at 1489 kg/ha, which was significantly lower (at the 5% level) than the other treatments. For both creeping and semi-creeping bean varieties, the highest yields were achieved using bed cultivation. Economic analysis revealed that cultivation on 30 cm and 80 cm wide beds was the most cost-effective method. The length of irrigation tape required for flat planting was 2000 m/ha, compared to 13,500 m/ha for bed planting methods. Given the advantages of bed cultivation, flat planting (conventional method) is not recommended for bean production.
