Indonesian farmers examine mature IR5 rice from a trial and demonstration plot. - - Freedom From Hunger campaign Fertilizer programme.. Demonstration plots are an effective means of convincing farmers of the importance of using fertilizer. A farmer is given fertilizer and improved seed, when available, for planting a portion of his field, and the rest is planted in the traditional way. When the corps mature, neighboring farmers are brought to see the differences between the two plantings and the improvements achieved by selected sees and fertilizer. This is the basis of the FFHC insustry-spomsored fertilizer programme, now underway in 31 nations. In 1968 this programme was begun in Indonesia, and the Food and Agriculture Organization (FAO) sent Mr. K. Kuiper (Netherlands), Soil Fertility expert, to assist the Ministry of Agriculture?s Extension Service in carrying out the programme in Jogjakarta province, Java. The expert has conducted training courses for extension workers to show them how to organize demonstrations, how to lay out fertilizer trial plots, and how to interest village leaders and farmers in experimenting with fertilizers and improved rice varieties. Only six months after the project began, 225 fertilizer demonstrations were held and 40 trial plots were planted in key villages all over the province.
