What are 4 effects of temperature on crop growth?
Temperature influences most plant processes, including photosynthesis, transpiration, respiration, germination and flowering. As temperature increases (up to a point), photosynthesis, transpiration and respiration increase.
Changes in ozone, greenhouse gases and climate change affect agricultural producers greatly because agriculture and fisheries depend on specific climate conditions. Temperature changes can cause habitat ranges and crop planting dates to shift and droughts and floods due to climate change may hinder farming practices.
However, when there is a heat wave and soil temperatures increase, plant roots are less able to compensate for varying levels of soil moisture within the soil profile. When soil temperature rises above an optimum threshold, plant water and nutrient uptake can be impeded, causing damage to plant components.
The four most important factors that influence crop yield are soil fertility, availability of water, climate, and diseases or pests.
High temperature, even for short period, affects crop growth especially in temperate crops like wheat. High air temperature reduces the growth of shoots and in turn reduces root growth. High soil temperature is more crucial as damage to the roots is severe resulting in substantial reduction in shoot growth.
Warmth induces vegetation development in terms of water and nutrient uptake and overall plant growth. Low temperatures inhibit water uptakes due to lower water viscosity and slow down the process of photosynthesis.
In annual crops, higher temperatures can drive shorter life cycles, resulting in less seasonal photosynthesis, shorter reproductive phase, and thus lower yield.
These factors are grouped in three basic categories known as technological (agricultural practices, managerial decision, etc.), biological (diseases, insects, pests, weeds) and environmental (climatic condition, soil fertility, topography, water quality, etc.).
Environmental factors that influence the extent of crop agriculture are terrain, climate, soil properties, and soil water. It is the combination of these four factors that allow spe- cific crops to be grown in certain areas.

What are the 4 main factors that affect temperature?
The main factors influencing temperature include latitude, altitude, distance from oceans and lakes, and ocean currents. First, Earth's surface is divided into three temperature zones based on latitude. The tropical zone is near the equator and has a warm climate since it receives direct sunlight all year.
- The latitude of the place.
- The altitude of the place.
- Distance from the sea.
- The air- mass circulation.
- The presence of warm and cold ocean currents.
- Local aspects.
- the latitude.
- height above sea level.
- distance from the sea.
- ocean currents.
- prevailing winds.
Temperature is the measure of the average heat or thermal energy in a substance. Air and water temperatures are primarily determined by the amount of sunlight that is absorbed by the surface of the Earth, and the amount of heat that is re-radiated in the atmosphere by the greenhouse gases.
The most important factor is latitude because different latitudes receive different amounts of solar radiation. The maximum annual temperature of the Earth, showing a roughly gradual temperature gradient from the low to the high latitudes. The Equator receives the most solar radiation.
The two most important factors in the climate of an area are temperature and precipitation. The yearly average temperature of the area is obviously important, but the yearly range in temperature is also important. Some areas have a much larger range between highest and lowest temperature than other areas.
- The latitude of the place.
- The altitude of the place.
- Distance from the sea.
- The air- mass circulation.
- The presence of warm and cold ocean currents.
- Local aspects.
Overview. Many factors affects temperature. Among them, three factors that affect temperature are altitude, latitude and distance from sea. This note provides an information about the factors affecting climate.
The most important natural factors are: distance from the sea. ocean currents. direction of prevailing winds.
