The engagement covered cocoa, coffee, animal health, pest management and chemical safety and was intended for farmers, managers and extension officers.
The program was delivered last week by Farmset chemical specialists Colin Mitchell and Steve Woodhouse; and NAQIA's regional veterinary surgeon Ian Russel Enriquez.
The events were coordinated by the Highlands Farmers & Settlers Association Inc (HFSA).
HFSA President Wilson Thompson said there were 30 participants in the Madang training, 15 for Kainantu and more than 100 in Goroka.
