1. SURVEY ON THE DEVELOPMENT OF CROP MODELS IN INDONESIA
A Progress Report by:
Budi I. Setiawan,
K.Honda,
R. Chinnachodteeranun,
Gardjito,
M.Taufik

2. BACKGROUND
IMPORTANCE TO KNOW ACCURATE PLANT GROWTH, HARVEST TIME & EXPECTED YIELDS
CROP MODEL NEED TO BE DEVELOPED AS A VALUABLE TOOL.
CROP MODEL SHOULD BE USABLE & UNDERSTANDABLE BY ANY CONCERNING PARTIES:
Farmers
Managers
Supervisors
Policy makers
Model Developers

Crop Modelling

3. BACKGROUND
CROP MODEL SHOULD ENABLE TO RESPONSE DYNAMIC ENVIROMENTAL CHANGES.
CROP MODEL SHOULD CONSIDER INFLUECING FACTORS:
Determining factors:
Genotype, solar radiation, temperature, and else.
Limiting factors:
Water, soil nutrients, and else.
Reducing factors:
Pests, deseases, weeds, pollution, and else.

4. BACKGROUND TO CREATE SUCH CROP MODEL NEEDS:
Robust monitoring system.
Interactive to various users.
Capable to developed by others.
Common data be shared by others.
BEFORE CREATING SUCH CROP MODEL NEED TO KNOW DEVELOPMENT OF CROP MODEL.

5. PURPOSES To know crop models for 6 commodities developed in Indonesia:
Paddy
Corn
Cassava
Sugarcane
Oil Palm
Rubber
To the status of the models
To identify scientits and institutions developing the models.
To form a research network on crop models.

6. METHODS Collect articles, research reports, etc.
Communice with the authors.
Round table discussions.
Select competent scientists and institutions.
Site visit to the selected institutions.
Interview with other scientists in sites.
Hold seminar and workshop.

7. RESULTS Documents: Crop Models: Paddy: 13 docs. Corn: 20 docs.
Cassava: 4 docs.
Sugarcane: 8 docs.
Oil Palm: 10 docs.
Rubber: 5 docs.
Crop Models:
Most models based on statistical analysis
There were ORYZA _W and 2000 but only for introduction.
Others: System Dynamics, Artificial Neural Networks
