Python library for simulation of wheat phenological development, crop growth and yield at large scales
Project description
Welcome to PyWheat
Python library for simulation of wheat phenological development, crop growth and yield.
Intro
The PyWheat simulates the wheat growth and development in a daily time-step. Most of the algorithms are based on the original routines of the CERES-Wheat 2.0[^1]. PyWheat model has also much in common with the N-Wheat model. Improvements of both models carried out in DSSAT 4.7.5.11 [^2] and APSIM-Wheat 7.5 R3008[^3] are included gradually in this beta version.
To accurately simulate wheat growth, development, and yield, the model takes into account the following processes:
- Phenological development, especially as it is affected by genetics and weather.
- Extension growth of leaves, stems, and roots.
- Biomass accumulation and partitioning, especially reproductive organs.
- Soil water balance and water use by the crop.
- Soil nitrogen transformations, uptake by the crop, and partitioning among plant parts.
Quick start
The package for estimating wheat grain yield using pywheat can be installed with pip
:
pip install pywheat
