A spatially based spectral library was developed for Uma rice

The Kerala  Fisheries and Marine Research University and the Center for Water Resources Development and Management (CWRDM) have successfully developed a spectral library of Uma rice, a popular local rice variety in Kerala, using space technology.  A team led by Girish Gopinath of Kufose used remote sensing to study  variations in the spectral signal of Uma at different growth stages and identified spectra indicative of water stress conditions. Girish Gopinath said the space-based spectrum could revolutionize the monitoring of  rice cultivation in Uma, reducing the need for extensive field work, labor and costs. U Surendran led the CWRDM research team. The study, titled “Development of Spectral Library for Hyperspectral Data with Special Emphasis on Paddy”, was funded by the Kerala State Council for Science, Technology and Environment with a grant of ₹ 83.5 lakh. Stress resistant high yielding variety  Uma rice, also known as “wavy rice” characterized by its round shape and glutinous texture, is a popular rice variety released by the Mancompu Research Station of the Kerala Agricultural University in 1998. The Uma variety has been popular in Kuttanad since  its inception.

    It later became the most widely cultivated variety in Kerala. It holds a special place in the culinary landscape of Kerala, contributing to the state’s diverse food culture. Despite the challenges of paddy cultivation in Kerala due to climate change and related extreme events, Uma rice remains a staple. This library makes it possible to accurately assess the spatial distribution of the Uma variety in specific areas, to understand its current growth phase, and to assess the effects of water or nutritional stress. In addition, it enables performance evaluations using remote sensing images.
