We had lecture of Cost & Revenue Analysis lecture by JICA Expert. We had interview to farmers about farm management, and we analyzed the data. we have to consider income, inputs, labor cost, depreciation, etc. And we had to get these information from farmer. I realized how important is recording everyday. A farmer couldn’t answer amounts well. Another farmer could answer most of inputs and data. I thought the differences is that recording of farm activities. … After analysis, we could see farm management easier. What part has more loss, and what inputs are high cost for farming, and so on. This analysis is should be advising to farmers in the future. Probably our analysis practice is going to show how important to make own compost and use it.
