In order to solve the shortage of roughage supply for dairy farm in Korea, winter cereal forage production after harvesting of rice in the fallow paddy field was studied. Two parts are already reported at the previous paper - One was the model development of the mechanized production, and the other was the study of feasibility of the model and its desirable direction in Korea. In this study, the model system is applied for a winter cereal wrap silage production model to practice in Kyungbook National University farm on 3ha scale for 3 years. Results of the research are summarized as follows; It takes 2 or 3 working days to process the wrap silage in middle of May in Daegu region. Also, not much particular problem can be found during the application test of mechanized wrap silage production. Field capacity and field efficiency are estimated to be 0.6-0.85 #13258;/h and 50-70% in mowing, 1.1 sim;1.7 #13258;/h and 52 sim;80% in tedding and raking, 0.6 sim;1.1 #13258;/h and 25 sim;45 #65285; in baling and 0.5 sim;0.57 #13258;/h and 75 sim;85% in wraping, respectively. Total production cost is estimated to be 1,257won/kg-TDN in oversowing and wrap-silage harvest in 1.6 #13258; working area. As a result, large scale field is recommended to produce the wrap silage in order to maximize the field capacity. |
