ABSTRACT = {Agriculture is a primary activity in many countries, with wheat being a major cereal crop in India. Accurate pre-harvest forecasts of crop acreage and production are critical for policymakers to address supply-demand dynamics, pricing, and trade. This study focuses on estimating wheat acreage and yield in Barwala block, Hisar district, Haryana, for the 2019–2020 Rabi season using remote sensing techniques. Multi-temporal satellite data capturing phenological stages of wheat (Seedling to Ripening) were processed using supervised classification with a maximum likelihood classifier in ERDAS Imagine. Wheat crop acreage was determined by overlaying ground truth points on the classified data. The estimated acreage showed a relative deviation of −1.07% compared to statistics from the Department of Agriculture (DoA), Haryana. Yield assessment employed a Semi-Physical model based on the Modified Monteith Model. Key parameters included Photosynthetically Active Radiation (PAR), fraction of PAR absorbed by wheat (fAPAR), light use efficiency, and water stress derived from the Land Surface Water Index (LSWI) using Sentinel-2 NIR and SWIR-1 bands. Net Primary Productivity (NPP) was computed for the wheat growth period, and grain yield was estimated using a harvest index obtained from literature. The estimated yield had a relative deviation of 9.3% from DoA data. The study demonstrates the potential of multi-temporal satellite imagery for accurate block-level wheat acreage and yield estimation, providing a valuable tool for agricultural planning and policy-making.},
