Agrometeorology

an introduction to agro-meteorology

1. By: Mr. Sandeep Singh PG Department of Agriculture GSSDGS Khalsa College, Patiala An Introduction to Agro- meteorology

2. Introduction Environment the aggregate of all external conditions & influence affecting the life & development of an organism, plays a dominate role in crop production. Climatology: is the science that seeks to describe & explain the nature of climate, how it differs from place & how it is related to human activities. It deals with average conditions representative of long term state of the atmosphere & its variability. Meteorology: as physics of the weather phenomena. It specially concerned with the physics of weather phenomena & deals with day to day atmospheric conditions & their causes. Greek word “ Meteoro ” means ‘above the earth’s surface’ (atmosphere) “logy” means ‘indicating science’. Branch of science dealing with that of atmosphere is known as meteorology. Cont……………….

3. Introduction Agro-climatology: the science that deals with the aspects of climatology having direct relevance to agriculture. It seeks to relate climatic regimes to agriculture production. Agro-meteorology: as a science investigating the meteorologic , climatologic & hydrologic conditions that are significant for agriculture owing to their interaction with the object & processes of agricultural production. Another definitions….. It is a branch of meteorology that examines the effect & impact of weather & climate on crops, livestock & various agricultural operations. Branch of meteorology, which investigates the relationship of plants & animals to the physical environment.

4. Intro……….. It is the science of meteorology to service of agriculture for sensible use of land, accelerate production of food & to avoid irreversible abuse of land resources. It is the study of response of living organisms to the physical environment. The living organisms are cultivated plants, livestock, insects & microorganisms. Task of meteorology is to apply relevant meteorological skill to helps farmers to make most efficient use of physical environment for profitable crop production.

5. Importance to Crop Helps in planning cropping patterns/systems. Reduction in waste of capital. Manipulation selection of sowing dates for optimum crop yields. Reducing losses of applied chemicals and fertilizers. Judicious irrigation to crops. Efficient harvesting of all crops. Reducing or eliminating outbreak of pests and diseases. Efficient management of soils which are formed out of weather action.

6. Climate & Weather Pertains to the day to day state of the atmosphere at a particular place. Refers to specific instant of time to and place. It is always changing & differs from time to time. Pertains to the atmosphere over a given region. Refers to a large region & for a long period of time. It is more or less stable and differs from region to region.

7. Scope of Agro- meteorology Its helps in improving the crop production as it is concerned with the interaction between meteorological & hydrological factors on one hand agriculture on other hand The scope of agro-meteorology is to make use of meteorology knowledge for sustainable agricultural system.
