Green Manure Boosts Maize Yield by Improving Soil Moisture and Photosynthesis

A three-year field study in Gansu, China found that returning green manure after wheat improves soil moisture and early-season soil temperature, strengthening maize roots and canopy cover. These gains raise chlorophyll (SPAD), net photosynthesis, and PSII efficiency while limiting NPQ, boosting biomass and grain yield. Green manure treatments outperformed conventional tillage across key growth and productivity indicators significantly overall consistently.
