Cropping Pattern

Back to Agrimet Division's Research Activities

By analysing the rainfall records of 2000 stations for 70 years, the periods and amounts of assured rainfall have been worked out for various regions particularly in the dry farming tract of India. The lengths of dry spells and wet spells during the monsoon, drought-proneness and agro-climatic classifications have also been studied with climatological data. This information is helpful in

1. Choosing appropriate crops for various regions

2. Determining the most favourable growing seasons for rainfed crops

3. Selecting drought-tolerant crop strains.
