Monitoring of wheat crop growth plays a crucial role in ensuring effective agricultural management and enhancing food security. Valuable insights into the spatial distribution and various growth stages of wheat crop can be obtained through the combination of multi spectral remote sensing datasets, data analysis, and ground-truth verification. This work aims to monitor the wheat crop at the farm level in the Bathinda district of India during the agricultural year 2022-23. It involves collecting and analyzing multispectral satellite data collected and analyzed over five selected farmlands in study region. Preprocessing of the multispectral satellite data is performed including radiometric and atmospheric corrections. The wheat crop’s health and growth are examined by utilizing various indices such as Land Surface Water Index (LSWI), Normalized Difference Red Edge (NDRE), and Normalized Difference Vegetation Index (NDVI) retrieved from the time series remote sensing datasets. Furthermore, wheat crop monitoring is performed fortnightly data to encompass its health, moisture levels, and growth stages for individual farmland. Different farmlands have shown varying LSWI, NDRE, and NDVI values. Variations in crop growth and productivity were observed among farmlands due to differences in soil properties and sowing dates. The findings from this study offer valuable insights into the importance of timely sowing, crop health monitoring, irrigation management, and soil suitability in optimizing wheat crop production.
