Abstract
َAn experiment was conducted in split plots in arrangement a randomized complete block design with three replications at the Khomein Bean Research Station during 2022-2023. The main plots of the experiment were: planting on a bed with 80 cm a width (p1), planting on a bed with 30 cm width (p2) and flat planting (p3). The Sub plots were including bean vareties: line 492 ,type one and upright (v1), Kusha variety, type two and semi-creeping and (v2) and Saleh variety,type three and creeping (v3). Machin field working capacity (ha/h), biology and dry grain yield (Kg/h), weight of 100 grains (g) and hrvest index were measured.The results showed that the highest grain yield was obtained in the planting on a bed with a width of 30 and 80 cm, with values of 2349 and 2261 kg/ha, respectively. The lowest yield was related to the flat method (conventional treatment), with an amount of 1489 kg/ha, which was significantly different( at the 5% level) from thoes of two other treatments. In both bean vareties of creeping and semi-creeping, the highest yield was related to the bed cultivation method. Economic analysis of the treatments showed that the method of cultivation on beds with a width of 30 and 80 cm is the most economical cultivation method. The amount of irrigation tape consumed in the flat method was 2000 m/ha:while the tapee consumed in the two treatments planting on the bed was 13,500 m/ha. Flat cultivation of bean (conventional method) is not recommende
