In order to clarify the effects of the seeding rate and the preparing method of silage on the quality of silage, the paddy rice, cultivar Kinmaze, seeded on drained paddy field was grown on flooded paddy field after fourth leaf age. The seeding rate was 8,16 and 32kg/10a. To make a whole crop silage, rice plants were harvested during a period from milk-ripe to dough-ripe stages (15 to 20 days after heading). The farm operating systems for harvesting rice plants as whole crop silage were investigated using a forage harvester and a head feeding type combine. The rated output of the engine of the combine was 9.5PS and cutting rows were 2. The farm operating systems using the head feeding type combine were classified into 4 groups according to with or no threshing and using a packing or combine cutter. The rice plants packed in a sack were carried to the farm road by a crawler type self running carrier and transported to the trench silo (about 1m×1m×2m) by a truck. When the combine cutter were used, the rice plants were cut and scattered on the field, and transported to the silo by a pick-up wagon. The number of culms per unit area and leaf area per unit area increased with a increase of the seeding rate. On the contrary, the length of culm and ear increased with a decrease of the seeding rate. Consequently, the yield of rice plants per unit area was not significantly different among the seeding rate. No consistent effects of the seeding rate and the preparing method of silage on the chemical composition of the silage (feeding value) were observed. The rice plants harvested with the combine produced a good silage by drying them before storing into the silo. And also, the rice plants harvested by the forage harvester (flail type) produced a good silage. But, the baling treatment before storing did not give a good silage. The efficiency and loss of the farm operating were investigated. The farm operating loss was about 30-40%, which was thought to be resulted from the loss of blower and choking. The farm operating efficiency was in a range of 40-80%.
