抄録

In the paddy region, it is an important to develop contractors to increase roughage production. This paper examines the conditions of contractor by simulation of contractor model under the following four limitations: 1) Contractor does not select dent corn and sorghum due to poor drainage; 2) Contractor must manage agricultural management entity privately; 3) Contractor must harvest foraged rice to support change of crops for rice farmers; 4) Harvest or gathering operation must use roll baler. Our contractor model is built by linear programming.<br>Some meaningful results have been found in this work. Firstly, the contractor needs to forage rice, straw, and grass for harvest activity to ensure profit and to maintain permanent hired workers. Secondly, sales price of forage rice should be maintained to avoid competition with straw gathering activity. Thirdly, in case the operating efficiency of harvesting is low, it is important to ensure profit to maintain straw gathering period long term. If rice farmers hope to develop contractors, they should delay tilling paddy fields until after harvest of rice.
