The Indian Green revolution region “Indo Gangetic Plain” occupies nearly 15% of the total geographical area of the country. The study area covered five states (Punjab, Haryana, Utter Pradesh, Bihar & West Bengal) in the Indian part of IGP, extended from 73º E and 32º N to 89º E and 21º N. Rice- wheat system is a main food security system of the India. The analysis of rice yield with rainfall CV=0.10 was observed and coefficient of correlation between rainfall and yield was 0.44 and wheat was computed which less than linear function is provided value of R2 of 0.55, which is reasonably less indicating that 55% variation in wheat yield is explained by the yearly rainfall. The major agricultural areas identified the rice-wheat crop calendar was identified using the SPOT VGT IMAGES. The images were classified in ERDAS Imagine using Density slicing classification (Un-supervised) algorithm. The analysis of kharif and rabi time series data; the overall analysis of total DN values are divide in three range classes viz. 128, 128- 192 &192 assigned in pink, yellow and green, and re-classified in low, medium and high agriculture area. The overall DN values of kharif and rabi season average temporal data analysis are observed medium class (128-192) have 46.6% and 57.1% values coverage area and high coverage area having only 13% and 17.6 % respectively. The remote sensing and GIS technology play an important role to control and management of problematic areas. The long term study of satellite data are help to monitor with latest technology for save fertilized crop land.
