Title: Utilization of Farm Power and Machinery in Wheat Farms in Saudi Arabia
Authors: Al-Suhaibani, Saleh A
Issue Date: 1993
Abstract: The wheat production in Saudi Arabia doubled 37 times during the period 1975-1990. Tractors and field machines were introduced on large scale and at very high rate. Consequently, some difficulties and problems occurred due to lack of research programs and limited experience of the farmers. The objective of this research is to evaluate the utilization of field machines and tractors power in the middle region of Saudi Arabia. A survey was conducted to collect data from 37 wheat farms. Data collected included farm area, soil type, tractor power, machine size and field operations data (depth, speed, field time] and working policy. For each farm, field efficiency and loading factor for each field operation were calculated. Field efficiencies were 49%, 37%, 34%, 46%, 31% and 58% for moldboard plowing, chiseling, harrowing, seed drill, harvesting and baling respectively, which is lower than that recommended by ASAE (ASAE, D497). Moreover, efficiencies greatly varied among the farms for each specific operation and they were not dependent on the farm area. Also the average loading factor of tractors was low and ranges 24% for seed drill to 67% for chiseling. The mechanization provision of tractor power and machine size was very high compared with other studies. It is suggested that poorly utilization of tractors and/or machines, should either expand their size whenever this is possible, lease the extra equipment or sell them. Also, it is necessary to establish a data bank with information needed for farm machinery selection, as well as with suitable selection models.
