2005 Work Plan Summary*
Ubon, Thailand and Raipur, India
|
Key Site: Ubon Rice Research Center, Ubon Ratchathani, Thailand
IRRI team: G. Atlin, S. Haefele, D. Johnson, T. Paris, G. Jahn, S. Pandey
URRC team: V. Chamarerk, B. Jongdee, Y. Konboon, P. Romyen, K. Naklung

Nutrient management: Plans call for a) dry-season pot experiments, and wet-season field experiments, to evaluate the effect of carbonized residues as a soil amendment in low-CEC soils, b) split low-rate N applications to test efficiency in both upper and lower fields, and c) further analysis of Northeast Thailand's nutrient management data to refine the decision tree for nutrient management options.
Weed management: Experiments will investigate a) a reduced set of treatments involving farmers practice, post-emergence herbicides, and seed soaking combined with mungbean, in order to measure costs and benefits, and b) yield losses from weed species in upper and lower fields. Work will continue on developing a decision tree by surveying farmers on their practices.
Insect management: Multiple-location experiments will assess crop loss to insects by comparing a) organic versus non-organic practices, and b) regimes that include no insecticide, farmer practices and scheduled insecticides. The same study will be used to compare arthropod diversity in organic versus non-organic fields at various crop growth stages.
Germplasm improvement: Farmers will participate in the evaluation of promising lines for upper fields, and those obtained from NARES and IRRI-URRC breeding programs. URRC will continue to evaluate donors for high yield potential and drought tolerance.

Continued on-farm testing of cropping systems with varied establishment, weed control and nutrient management options. The experiments will involve participatory management selection methods, which allow farmers to evaluate and express their preferences.
On-station evaluations of major cultivars under promising herbicide treatments.
Continued on-farm testing and analysis of urea deep placement practices.
On-station drought-tolerance screening.
Participatory varietal selection (PVS) trials of two kinds of materials based on duration and adaptation to the toposequence.
Training IGAU partners on IRRISTAT, PVS, and breeding strategies.
Initiate the development of extension bulletins, pamphlets and posters.
Develop a decision tree to guide farmers through establishment and weed management options.
