A new quarterly newssheet is being put out by the US Office of Agriculture, Bureau for Science and Technology/AID (Agency for International Development) in Washington ~C:.
STAR (Science and Technology Agriculural Reporter) was initiated ~ response to a demand for regular communications between AID's Office of Agriculture and a worldwide audience. It provides current information on collaborative research programmes sponsored by AID/S and T/AGR, and shares research findings, explores applications, and discusses accomplishments. As such it invites contributions on project accomplishments and now aid-funded agricultural research is making an impact.
SIAR's objective is thus to increase professional collaboration avoid duplication of professional effort, and facilitate the transfer of agricultural technology.

Cassava multiplication in plastic bags
Cassava ministem cuttings popped into polyethylene sprout within seven days. The sprouted cuttings establish more quickly in the field and the crop is thus ready for harvesting earlier.
Five years ago scientists at the International Institute for Tropical Agriculture (IITA), Nigeria, developed a technique for sprouting cassava cuttings. This involved putting the cuttings into plastic bags with soil. The cuttings took four to six weeks to sprout, and there was the added labour for handling the soil. There was also the danger of the soil carrying pests and diseases.
With the new technique the minister cuttings are dipped in a fungicide, then they are put directly into perforated polyethylene bags and stored in a shaded area. Depending the variety of cassava, 95% to 100% of the cuttings sprout within 7 days. High humidities and temperatures promote a quick and uniform sprouting. In trials with three varieties of cassava, sprouted cuttings were transplanted into the field. After eight weeks 86% to 89% of the cuttings were growing well.
