A collaborative effort between scientists from the Kerala University of Fisheries and Ocean Studies (Kufos) and the Centre for Water Resources Development and Management (CWRDM) has resulted in the development of a spectral library for Uma rice, a beloved indigenous rice variety in Kerala, utilizing space technology.
Led by Girish Gopinath of Kufos, the team employed remote sensing techniques to analyze spectral variations in Uma rice plants at different growth stages, notably identifying water stress conditions. The newly created spectral library is anticipated to revolutionize precision farming practices, offering enhanced crop management strategies, as stated by T. Pradeepkumar, Vice-Chancellor at Kufos.
The spectral library facilitates precise assessments of Uma rice’s spatial distribution in specific locations, aids in understanding growth stages, and evaluates the impacts of water or nutrient stress. Additionally, it enables yield estimates through the utilization of remote sensing imagery.
Dr. Gopinath highlighted the transformative potential of space technology-based spectrums in monitoring rice cultivation, potentially reducing the necessity for extensive fieldwork, labor, and associated costs. The team of scientists from CWRDM was led by U. Surendran.
Funded by the Kerala State Council for Science, Technology, and Environment with a grant of ₹83.5 lakh, the study titled ‘Development of spectral library for hyperspectral data with special emphasis on paddy’ contributes to advancing agricultural practices.
Uma rice, colloquially known as ‘unda rice,’ is renowned for its round shape and sticky texture. Introduced in 1998 from the Mancompu research station of Kerala Agricultural University, Uma rice has gained popularity in Kuttanad for its high yield and stress tolerance. Despite challenges posed by climate change affecting paddy cultivation in the State, Uma rice remains a staple, displaying resilience against uneven rainfall triggering drought conditions and water stress.
