In addition to rice or coffee, many Indonesian farmers grow vegetables such as hot peppers, tomato, cucumber or cabbage. Unfortunately, the quality and yield of these vegetables is often too low. This is why Wageningen University & Research plant scientists started a programme called VegImpact in which they have trained over 10,000 Indonesian farmers in efficient vegetable farming. The farmers were introduced to improved vegetable varieties, and taught about adequate fertilisation and how to protect crops against pests and diseases in a responsible way.
