DRYLAND

Length of Growing Period

Length of growing period is defined as a period in which the available soil moisture is enough to meet the evapotranspiration requirement of dry land crops and hence the dry land productivity is assured.
The length of growing period is given as ‘G’ with starting and ending of length of growing period in terms of Meteorological standard weeks.

Length of growing period	Crop Status
< 5 weeks	Crop failures will occur
Minimum of 14 weeks (98 days)	Permit the dry land crop to attain its potential productivity
14 weeks	A single dry land crop can be cultivated
14 to 20 weeks	Suitable inter cropping system can be cultivated
> 20 weeks	Long duration crop / double crop can be cultivated
