The agricultural worker share of the land 41.72 ha/man. The cost of mechanization to planting one hectare was 14382 ID. The percentage of mechanization cost of total costs 44%. The effectiveness of total capital was 1.48. The effectiveness of mechanization capital was 3.61 where yields were 264.2 kg/ha.
