Effects of Greenhouse Covering Materials in Tomato Cultivation for Warmer Temperatures

Publication date July 25, 2018

Region name Chubu(Ishikawa Prefecture)

Climate change impacts

An increase in climate change-induced heat waves is resulting in increased damage to agricultural produce. In tomato production, fruit splitting from higher summer temperatures is impacting the yield of saleable produce.

Adaptation activity

Applying a light-shielding material to the exterior surface of polyethylene greenhouses has been found to prevent fruit splitting. However, if too much light is blocked this may also reduce yield. The Ishikawa Prefectural government is supporting research into the effectiveness of thermal barrier netting that protects tomatoes from cracking and ensures yield.
