Agricultural meteorology deals with the relationship between weather, climate, and the growth of cultivated plants and animals. It helps farmers plan cropping patterns, reduce costs and losses, select optimal sowing dates, harvest efficiently, and manage pests and diseases. Key parameters that must be measured include atmospheric temperature, wind, humidity, moisture, and light. Weather is the current physical conditions of the atmosphere while climate is the long-term average weather conditions of an area over 30 years. Climate and weather play major roles in determining the success of agriculture.

2. Agricultural meteorology
• Agricultural meteorology is the applied branch of meteorology,
which deals with the relationship between climate, weather, life and
growth of cultivated plants and animals.
• Greek word “Meteor” means above the earth’s surface’(atmosphere)
“logus” means ‘indicating science’. Branch of science dealing with
that of atmosphere is known as meteorology.

3. Importance to crop production
• Helps in planning cropping pattern/systems.
• Reduction in waste of capital.
• Manipulation selection of sowing dates of optimum crop yields.
• Reducing losses of applied chemicals and fertilizers.
• Efficient harvesting of crop.
• Reducing or eliminating of outbreak of pest and diseases.
• Efficient management of soil which are formed out of weather action.

5. Weather
• Weather can be defined as physical condition or state of the
atmosphere at a particular time and place.
Eg. Cloudy day

7. Importance of weather
• Weather plays a major role in determining the success of agricultural
pursuits
• Most field crops are dependent solely upon weather to provide
life‐sustaining water and energy
• Adverse weather conditions can cause production losses, especially if
experienced during critical stages of growth.

8. Climate
• Climate is the long term average of weather, typically averaged over a
period of 30 years of a region or place.

9. Importance of climate
• By knowing the climate of your particular region you can decide what
to grow.
• The climate affects the availability of water in certain regions where
irrigation is not available.
• Climate also affects the soil where you want to grow crops.
