Study has been conducted to analyses length of growing period use NDVI value. The LGP is normally analyses weather station data. In this study LGP analyses using NDVI data (1992-2015) from public domain AVHRR (Advanced Very High Resolution Radiometer) 1km resolution for Coimbatore regions. The duration of the growing period was calculated using the NDVI threshold value and compared to the NBSS&LUP normal length of growing period (1999). For J. Reddy technique validation, ground station data such as rainfall and PET analyzing LGP are used. According to the study, the maximum LGP was found in the Karamadai, Pollachi north, and Pollachi south regions, while the lowest LGP was found in the sulur region, and short-duration crops were recommended.
