PySawit v. 0.0.1 (README)
Oil Palm Growth and Yield Model
PySawit is a model, written in Python language, to simulate the growth and yield of oil palm. The following are various conditions among which PySawit is able to simulate:
- different planting densities
- different weather conditions (such as air temperature, rainfall, etc.)
- different soil properties (such as soil texture)
- different crop physiological conditions (such as flower sex ratios, specific leaf area, plant nutrient content, photosynthetic parameters, etc.)
At the moment, PySawit simulates crop production level 2, where oil palm is limited only by meteorological and soil water availability. Nutrients, pests, diseases, weeds, and other field practices are assumed to be optimally managed.

To simplify the installation process, download the
Anacondasuite. Make sure you only choose the Python version 3.5 or higher (NOT ver 2.7). Downloading the
Anacondasuite will include not only the Python interpreter but also the
xlwingsmodules which are required by PySawit.
Then, at your system's command line or prompt, type:
pip install pysawitto download and install the PySawit.
If you want the Excel user-interface to PySawit and the example files, just download the files from the
examplesfolder. Or download the entire
You may also want to download and install
Graphvizif you are planning to use PySawit's tracing feature to plot out a map of the program flow. Ensure you read the
Graphvizwebsite on how to set up the environment variable to recognize the location of graphviz files.
How to use
Call Python on
pysawit.py. See this file's documentation on the commandline flags or options.
