This document presents an analysis of seasonal agricultural patterns and changes in the blocks of Malda District in West Bengal, India using geospatial technology. There are 15 blocks in Malda District. The study aimed to analyze block-wise seasonal distributions of crop land, horticultural land, and non-vegetation land. Satellite imagery from LANDSAT 8 and field survey data were used with software like ArcMap and Erdas Imagine. Methods included NDVI, NDWI, supervised classification, and thresholding to extract land types from imagery from February, April and September. Results showed little change in non-agricultural vegetation but shifts in crop land between blocks by season, with more cultivation in winter in some blocks and largest

24. RESULT & COONCLUSION
 There is no such change in non-agricultural vegetation land among blocks in
February to April
 In Chanchal-II, Gazole, Kaliachak-III block we can see more cultivated land in
winter season
 Habibpur, Chanhal-II block have most cultivated land in the month of April.
 In the month of September we can see Gazole block has captured largest
agricultural area mainly paddy field
 There is no seasonal change in Horticultural Land, in English bazar, Ratua-II,
Kaliachak-I, Kaliachak-II, Kaliachak-III block have more horticultural (mango,
lychee tree) cover.
