Notes: India’s first Prototype Fast Breeder Reactor (PFBR) at Kalpakkam in Tamil Nadu is expected to be commissioned next year. It marks a major step in the second stage of India’s three-stage nuclear power programme. The PFBR is a 500 Megawatt electric (MWe) sodium-cooled reactor that uses fast neutrons instead of slow neutrons.

Notes: The Indian Space Research Organisation (ISRO) has predicted that wheat production from eight major states will reach 122.724 million tonnes by March 31, 2025. This estimate was made using satellite-based remote sensing technology for better accuracy and timely updates. ISRO’s National Remote Sensing Centre (NRSC) has developed a system called CROP, which stands for Comprehensive Remote Sensing Observation on Crop Progress. CROP is a semi-automated and scalable system that monitors crop sowing, growth, and harvesting in near real-time. It mainly supports agricultural planning during the Rabi season. This comes as remote sensing in agriculture marks 50 years of global use.
