Sri Lanka programs / Sri Lanka project 383-0058 · 1991–1993 · Development Alternatives, Inc. (DAI)
The first of its kind compiled in Sri Lanka, this annotated bibliography assembles information from the numerous studies on specific weed species and weed management methods that have been conducted in the country's annual and perennial crop sectors during the past several years. Surveys in lowland rice fields have identified about 120 weed species belonging to 32 families, and there are estimates that weeds reduce crop yields by about 25% to 30%, while weed control accounts for nearly one-third of production costs. Due to the extent of this problem, a thorough knowledge of previous research is essential for designing future weed management programs. Citations include research publications on general aspects of weed control, weed control in various crops (rice, upland crops, tea, rubber, and coconut), biological weed control, herbicides, and special weed problems, each with a full abstract. Includes author and subject indexes.

When the program ran, from its start year to the latest document year. A hatched bar means the start is our estimate.
Axis: award years, end from years in documents. The start year comes from award fiscal year; the end is the latest document year, so the program may have run longer.
A few documents to read first. Each opens in the side panel, with the PDF to download.

DEC topic and subject tags. They describe the documents, not what the program was. Each tag opens its evidence in the drawer.
Programs worth reading next, by topic, implementer, country and years. Similar by facets (topic, implementer, country, years) and, when available, description. It says the programs look alike, not how they are related in time. Source: catalog facets
