Crop combination analysis technique locates and identifies area sharing a significant proportion of crops at higher rank. Which aids in understanding the crop diversification, and operation of a given area, allowing for the creation of agricultural regionalization and a rough sketch of agricultural topology. The present study has been carried out to Monitoring the long-term crop combination followed by the farmers of North-western Haryana. Landsat-5 and Sentinel-2 based remote Sensing processed data has been used from the period of 1990-91 & 2021-22. The Doi crop Combination Statistical method (1959) has been used for the identification of crop combination in the agriculture of North-western Haryana. The major crop are cultivated in North-western Haryana are Wheat, Mustard, Rice, Cotton, Bajra, Gram and sugarcane etc. The lowest deviation has been estimated in two crop combination during the reference period and the highest deviation has shown shift from four crop combination during 1990-91 to mono crop combination during 2021-22. The two-crop combination deviation is estimated is 196.76 during 1990-91 & 14.19 during 2021-22. Thus, the statistical analysis exposed that the two-crop combination is favourable for practicing in the agricultural North-western Haryana.
