FARMER EVALUATION OF SOYBEAN PLANTING PATTERNS

Overview

To identify the planting pattern of soybean that increases the production of the crop in Malawi without compromising on yield and economic returns. Specific objectives 1. To allow farmers evaluate the performance of soybean planting patterns so that they can choose the one convenient for their area for large scale production of soybean 2. To demonstrate improved agronomic practices in soybean production Expected outputs • Soybean planting pattern with higher grain and biomass yields with potential for reducing labour selected and characterized • Farmers adopt improved soybean agronomic practices for increased soybean yields and yield components

Protocols

The One v3.0 (Phi2, NPQt, using Multi-Phase Flash)

The One Protocol to rule them all! Phi2, NPQt combined.

Changes from previous The One protocol: - Removed the Phi1 measurement, which was producing a lot of invalid data (removed by Dan and Frank) - Implemented the multi-phase flash protocol created by Tom Avenson

Chlorophyll content (SPAD) III

REQUIREMENTS: Firmware v0.41 or higher. Measures transmission at 940nm and 650nm in order to determine the 'greenness' of a leaf, an indicator of chlorophyll content and nitrogen content. The 940 is used to account for leaf thickness. Improvements over Chlorophyll content (SPAD): - performs 3 different spads at 3 intensities for thin and thick leaves - auto-chooses appropriate intensity - is calibrated to a Minolta SPAD device from factory.

Improvements over previous version -

  • Compatible with firmware v0.41 or higher.
