Maize-bean intercropping


Testing the multispec tool in an intercropping trial in Tanzania.

Experiments are running in three zones at different altitudes on the slopes of Mt Kilimanjaro. In each zone, an intercropping trial is established with five plots: 1. Sole maize 2. Sole bean - local variety 3. Sole bean - improved variety 4. Additive intercrop: maize and local bean 5. Addtitve intercrop: maize and improved bean

Let's assess photosynthesis stress!


Leaf Photosynthesis - MultispeQ Beta ONLY

Measures photosynthesis-related parameters in <15 seconds, including: Phi2, PhiNPQ, PhiNO, NPQt, qL, LEF, and SPAD. In addition, measures PAR (photosynthetically active radiation), ambient temperature and relative humidity.

Works with the MultispeQ Beta device only
