Description	Not Available A study was carried out to develop useful. quantitative relationships between spectral indices (lR/R and NDVI) and leaf area index (LAl) in chickpea crop under irrigated and unirrigated conditions under field conditions. Six varieties differing in their growth habits and plant types were grown on sandy clay loam soils of Indian Agricultural Research Institute research farm during two rabi seasons of 2000-01 and 2001-02 under irrigated and unirrigated conditions following the recommended agronomic practices. The coefficients of determination (r2) values were obtained for the relations between LAI and spectral indices (lR/R and NDVI). Various types of regressions were tried and finally it was inferred that LAI can be best estimated by both lR/R and NDVI derived from the spectral reflectance data using linear or polynomial equations.
