I. Technical Services


I1. Biofuel Linkages

The Biofuel Unit will provide the advisory and coordination role on improvement to energy security, decreasing vehicle contribution to air pollution and reducing or even eliminating greenhouse gas emissions are primary goals compelling government to identify and commercialize alternatives to petroleum fuels currently. This section will coordinate and link to cassava, coconut, jethropha plant and sago development projects and work with the DAL Regional PISS offices including PNGBioNET, CEPA, NARI, NAQIA, Foreign Affairs and Trade, Commerce and Industry, Universities, Private Sector and NGOs.


I2. Taro and Mushroom Development

 Taro has been cultivated as a food crop for 3 000 years in the pacific region. The crop is cultivated as lowland taro in the Philippines, Hawaii, Asian and other Pacific countries. In Papua New Guinea it is cultivated under un-irrigated conditions, although irrigated taro has been recorded from a number of areas.


The classification of common aroids to which taro belongs to is:

Family:            Araceae

Tribe:               Colocasiodeae

Subtribe:          Colocaseae;

Genera:            Alocasia, Caladium, Colocasia, and Xanthosoma.

Genus:             Colocasia is said to contain five species in the Asian tropics but seven species, two of them edible, have been reported as native in Indochina. The use of the common name “taro” should be applied to the tuber-producing species of the genus Colocasia.

Science of Taro as a Traditional Crop

The science nature of Taro (Colocasia esculenta) is one of five traditional staple food crops in Papua New Guinea. It is most important in forest area, especially in the lowlands where rainfall is well distributed throughout the year, but it is also grown as a minor food in highlands areas up to more than 2000m above sea level. Taro is the most important staple food in the Solomon Islands and many other Pacific Islands. The importance of the crop may be seen in the significant place accorded to taro in the legend and ceremony of the taro growers in Papua New Guinea and other Pacific islands. For instance certain varieties were restricted to big men or leaders.

Related edible species, most of which are emergency foodstuff, include Alocasia macrorrhiza (paragum), Cyrtosperma chamissonis (swamp taro), Xanthosoma sagittifolium (Chinese taro or taro kongkong) and Amorphophallus campanulatus (wild taro). Cyrtosperma is a staple food on some coral atolls where it is difficult to grow other food crops. Xanthosoma is becoming more popular in places where people can no longer grow enough Colocasia for their needs.

Almost the entire taro in Papua New Guinea is grown on a subsistence level. The importance of the crop has not been fully realized or appreciated because not very much taro is found in the market and little marketing exists on a large and international scale.

Taro is generally cultivated in forest clearings without the use of irrigation, chemical pest and disease control or fertilizers.

Yield could be increased with the introduction of better varieties, use of fertilizer, better weed control, disease and pest control and adoption of improved cultural practices.



In Papua New Guinea Mushroom has been part of our diet as food even before we understood the nutritional and medicinal value of it. The Popularity due to the knowledge of its nutritional value and medicinal properties. We have mushrooms that are edible and non-edible (poisonous). Mushroom grows anywhere and wild in forest on logs, tree stumps and even on lawns and fields including sago pulp wastes.

 What is a Mushroom

It is a macro-fungus with a distinctive fruiting body which can be either epigeous (growing above ground) or hypogenous (growing underground). Mushroom grows from spores (as seeds are for plants). Mushroom seed is called spawn (planting material).

 The High Value of Mushroom

 The edible mushrooms have high in protein. (NB: Protein is one of the most important nutrients in mushroom food.) Mushrooms contain all the essential amino acids. They are rich in lysine and leucine –  amino acids which are in few quantities or absent in the majority of the cereal used daily. Mushrooms have high vitamin content and are good sources of minerals. Mushrooms have relatively low levels of total fats and Mushrooms have high percentage of polyunsaturated fatty acid. It can be grown anywhere as long as the conditions for their growth and cultivation are met and is considered as hedge against famine and a possible cancer cure. There is an enormous potential for feeding 3rd world countries and with high cash income and as said it is the alternative protein source to meat.

 Where to grow Mushroom

  • Logs
  • Grasses – Grasses that are dried, threshed, packed in polypropylene bags and sterilized.
  • Under banana crops using old banana leaves
  • Agriculture wastes – organic substrates (waste from farms, plantations and factories)
  • Sago pulp waste 
  • Food and medicine for everybody


Anybody can grow mushroom as long as they have

  1. the proper technology

– New ways of cultivating

  1. proper substrate
  2. planting material called spaw
  • Spawn is like seed to crop. Unlike spore, spawn is already at its mycelial stage growing on its substrate
  • Substrate is material on which mushrooms grow on.

Three Factors

  • Environment control of temperature, humidity light and ventilation are important for mushroom growth (because not protected by skin layer).

Pests and Diseases

  • Acarids
  • Larvaes
  • Beetles
  • Caterpillars
  • Fungi
  • bacteria
  • virus
  • nematodes
