Crop acreage estimation is an essential component for forecasting crop production. Menthol mint acreage estimation is a necessity as the crop production data change every year due to fluctuations in the market prices of menthol mint oil; hence, the rate available to farmers also changes every year. These acreage estimation studies would be helpful in reducing the uncertainties of menthol mint production as lower price results in low production and high price results in higher production next year. Thus, it in turn would help in stabilizing the market prices. Nowadays, remote sensing technologies due to their availability and adaptability are being widely used for crop acreage estimation nationally and internationally. This study focuses on menthol mint crop acreage estimation in the Barabanki district of Uttar Pradesh, India, using 2017 Sentinel-2A satellite data. Adaptive maximum likelihood classification algorithm was applied after intensive ground survey to obtain reliable menthol mint crop acreage estimation for talukwise statistics. Results have shown that menthol mint was extensively cultivated in the Fatehpur and Barabanki taluks as compared to the Haidergarh and Ram Sanehi Ghat taluks of Barabanki district. Menthol mint crop acreage estimation in the study area was estimated to be about 58,284.70 ha with (89.13% and 87.23%; users and producer’s accuracy) with overall accuracy (90.67%) and kappa value (0.844). In this study, early and late menthol mint crop acreage estimation was also attempted and it was found that about 26,123.50 ha and 29,911.40 ha were the area of early and late menthol mint, respectively. This method can be useful for localized-level crop acreage estimation from early to mature stage of menthol mint during its growing season.

薄荷醇薄荷（Mentha arvensis L.）使用多时相卫星图像估算作物面积

作物种植面积估算是预测作物产量的重要组成部分。由于薄荷油的市场价格波动，作物生产数据每年都在变化，因此必须进行薄荷种植面积估算；因此，农民可获得的费率也每年都在变化。这些种植面积估计研究将有助于减少薄荷醇薄荷生产的不确定性，因为较低的价格导致低产量，而高价导致明年的产量增加。因此，这反过来将有助于稳定市场价格。如今，遥感技术由于其可用性和适应性，在国内外被广泛用于作物种植面积估算。本研究的重点是印度北方邦 Barabanki 地区的薄荷薄荷作物种植面积估算，使用 2017 Sentinel-2A 卫星数据。在密集的地面调查后应用自适应最大似然分类算法，以获得可靠的薄荷作物种植面积估计，用于 talukwise 统计。结果表明，与 Barabanki 区的 Haidergarh 和 Ram Sanehi Ghat taluks 相比，薄荷醇薄荷在 Fatehpur 和 Barabanki taluks 中得到了广泛的种植。研究区薄荷薄荷作物种植面积估计约为 58,284.70 公顷（89.13% 和 87.23%；用户和生产者的准确度），总体准确度（90.67%）和 kappa 值（0.844）。在这项研究中，还尝试了早期和晚期薄荷薄荷作物的种植面积估算，发现早期薄荷和晚期薄荷的种植面积分别约为 26,123.50 公顷和 29,911.40 公顷。
