Rice is one of the most important staple cereals in Iran and has a main role in providing the food security. Harvesting by hand postpone the rice harvesting stage, and facing late season rainfall, and increase of yield losses during harvesting. To determine the most suitable harvesting method in Gilan, three different harvesting methods (by hand, harvester and combine) were considered as treatments and four different cities as blocks. The effective farm capacity, percent of total losses, percent of harvesting losses, number of workers and harvest costs were determined. The difference of percent of total losses and other factors were significant in different harvesting methods. Effective farm capacity in harvesting with harvester was more than other methods. Harvesting by combine had the lowest losses percent (1.92%). In harvesting by hand 98.3 percent of harvesting costs were related to harvesting and collecting of crops. In lands that have been consolidated, using combine and in small scale the use of harvester are recommended.
