Abstract Objective & Background: The aims of this study were to investigate the effects of planting methods on riased bed with microirrigation and seed density on grain yeild and energy indicators of bean production.   Materials & Methods: In order to compare the effect of planting methods and seed density on bean line of COS-16 (Straight Type), a split plot experiment in randomized complete block design was carried out in Khomein Bean Research Station during 2016 and 2017 with 3 replications. The main plots were flat planting, single row on a ridge, double rows on a ridge and three rows on a ridges. Sub plots were seed consumption of 70, 120 and 170 kg.ha-1. The space between ridges was 75 Cm. Irrigation type was microirrigation (tape irrigation).   Results: Experiment results showed that the treatments of two rows on a ridge with seed consumption of 120 kg.ha-1 and single row on a ridge with seed consumption of 70 kg.ha-1 with yields of 2300 and 2225 kg.ha-1, respectively are beter than other methods. The lowest energy intensity with 34 MJ.kg-1 and the high energy ratio with 0.99 were related to these treatments. Energy intensity and energy ratio of conventional method were 53.7 MJ.kg-1 and 0.63 respectively.   Conclusion: The treatments of two rows on a ridge with seed consumption of 120 kg.ha-1 and single row on a ridge with seed consumption of 70 kg.ha-1 are recommended and the flat and three rows on a ridge planting methods does not recommended.
