Heat is used by the plant in order to grow and many plants thrive in warm environments. The rates of photosynthesis and respiration in plants both rise with increasing temperatures. This can cause an increase in growth rates, meaning the crop could be more productive. Some special varieties of plants/crops germinate at higher temperatures.
Warmer than typical maximum temperatures will impact cattle stress, reducing milk yields and reproduction of stock. When temperatures get too warm, they can “bake” crops in the field, cause the growth rate to slow and reduce the sugar content of produce, making fruits and vegetables less sweet. This leads to reduce crop yields and increased disease burden.
