Groundnut is an important oil seed crop largely grown under rainfed conditions in India. Uneven distribution and or failure of monsoon rain affects the plant growth and reduces the productivity When crop is subjected to water stress it closes the stomata leading to reduced photosynthesis. Detection of plant water stress and assessing the possible effect on the growth and yield of crop is often difficult and challenging. To study the effect of water stress on the spectral reflectance properties of Groundnut and to assess the water stress using hyperspectral indices, a pot culture experiment with groundnut variety CO-7 was conducted during 2016-17. In order to induce water stress, varying soil moisture regimes were created by altering the irrigation intervals as well as the quantity of water applied. | Hyperspectral remote sensing technique to detect water stress in groundnut
