SUMMARY
Pearl millet (Pennisetum glaucum L.) is a crucial cereal crop, particularly in arid and semi-arid regions, serving as a staple food source and livestock forage. This study investigates the quantitative relationship between spectral reflectance indices and LAI under NS and EW row orientations. The field experiment was carried out at the Research Farm of CCS Haryana Agricultural University, Hisar, Haryana during kharif season, 2022 with three cultivars, namely HHB 299, HC 20 Composite, and HHB 67 Improved sown in NS and EW row orientations. The results suggested that all three spectral reflectance indices, SR, NDVI and TVI can be used to predict LAI in pearl millet crop both under NS as well as EW row orientations with 95 percent confidence level as is evident from the r2 values; highlighting the potential of remote sensing for crop health assessment.
Key words: Pearl millet, spectral reflectance indices, LAI, row orientations
