ASEANCOF (DJF 2025) - Temperature(2) - Chart Description

In DJF, many countries in ASEANCOF will be at harvest (Indonesia,  Philippines) or planting (Laos, Myanmar, Thailand, Vietnam) season for the rice crop.

For rice crop at harvest stage, above normal temperature will delay rice harvest time and reduce grain filling rate, negatively affecting the crop yield.

For rice crop at planting stage, below normal temperature may impede germination and reduce seedling vigor, increasing seedling mortality.

Please see the Methodology for documentation of crop calendar and hazard affecting crops in ASEANCOF members.

In DJF, many countries in ASEANCOF will be at planting (Cambodia, Vietnam), mid-season (Myanmar) or harvest (Philippines) season for the corn crop.

For corn crop at planting stage, above normal temperature can lead to oxidative stress in corn seedlings, causing growth abnormalities.

For corn crop at mid-season stage, above normal temperature can negatively affect pollination during flowering and limit the kernel number.

For corn crop at harvest stage, above normal temperature can have negative affect by disrupting the plant’s phenology, reducing pollen viability, impacting the female component of the plant, altering biomass allocation, and reducing kernel number and weight.
