Abstract: A study was conducted to prepare a cropping pattern changes of Krishna delta region of Andhra Pradesh using satellite data, by following analysis in ERDAS and GIS environment. Sustainability of agriculture can be achieved through optimum cropping pattern or crop rotation in an area. Multi date satellite data of Landsat TM, IRS P6-LISS III and OLI satellite data were used for the generation of cropping pattern and extent of crops in kharif and rabi seasons. In the present study extent of crop in season wise and cropping pattern has been determined for rice, maize, sugarcane, cotton and rice-rice, rice-maize, respectively. Rice has been the dominant crop of kharif in the study area contributing to 59.77, 59.73 and 46.60 per cent followed by sugarcane contributing to 0.72, 1.46 and 1.81 per cent and cotton of 0.63, 0.50 and 1.07 per cent of the total geographical area in 1996, 2005 and 2015, respectively whereas, in rabi pulses were dominant crop and contributing of 44.09, 24.39 and 32.57 per cent of the total geographical area in 1996, 2005 and 2015, respectively followed by rice and maize. The extent of maize in the study area was found to be 53.43 and 76.86 (`000 ha) covering 8.56 and 12.32 per cent in 2006 and 2016, respectively. Temporal remote sensing data revealed a drastic reduction in extent of area in rice-pulse pattern with an increase in rice-maize in 2006 and 2016 compared to 1997.
