Documenting the production process in agriculture includes providing all information and activities that shows the course of production from seedbed preparation stage to harvest stage. For this purpose, in present investigation all management operations performed from seedbed preparation stage to harvest stage in the studied wheat fields in 2007 and 2008 were recorded through farms survey. In this study, the method of doing each management operation undertaken in farms from stages of seedbed preparation to harvest as well as a proportion of farmers applying different method of the management operations were determined through absolute and cumulative frequency distribution. The results showed wheat cultivation was conducted from 5 to 16 December. Depending on seedbed preparation quality and type of planting tool, the rate of used seed was varied from 140 to 250 kg ha-1. The more farmers used urea, triple superphosphate and potassium sulfate fertilizers for supplying nutrient requirement in wheat farms. Traditionally, urea fertilizer was used at stem elongation stage on average with amount of 93 kg ha-1. Due to shortage rainfall during the first year, the most farms were irrigated twice (at flowering and early seed filling) but in the second year it was done once (at flowering). The time of wheat harvest was ranged from 7 to 14 June depending on environmental condition. In respect to variation of management operations in farms, the amount of yield was varied from 2.5 to 6.3 t ha-1.
