PJTAU proposes SAR-based crop monitoring system
The project aims to deploy Synthetic Aperture Radar (SAR) data for the precise estimation of crop areas across the state. Minister Rao stated that such pre-season estimations will enhance the effective implementation of government schemes and enable more responsive policy decisions. He directed university scientists to prepare and execute the technology-based assessment plan by August–September, assuring full government support and funding for its implementation.
University scientists highlighted their ongoing experiments in collaboration with a Swiss company, demonstrating the effectiveness of SAR-based crop recording during the rainy seasons across multiple states. The precision achieved through SAR imagery enables the accurate tracking of crop distribution, even under dense cloud cover—a significant limitation in traditional satellite methods.
The review meeting explored future possibilities in agriculture, particularly focusing on how sensor technologies could help forecast pest attacks in advance. Minister Rao recommended that PJTAU (Professor Jayashankar Telangana State Agricultural University) begin field trials on various crops starting this season. Researchers highlighted that data generated by sensors allows for earlier detection and targeted pest control, outperforming traditional satellite systems in terms of responsiveness and detail.
As the state prepares to implement a new crop insurance scheme, the minister urged PJTAU to develop and distribute comprehensive technical guidelines to support effective policy implementation and enhance farmer awareness. The integration of SAR (Synthetic Aperture Radar) and sensor data will be crucial for risk assessment and claims processing under the forthcoming insurance framework.
The review included Dr. Sameerendu Mohanty, Professor of Practice; Dr. T.L. Neelima, Scientist; Dr. Y. Balaram, Research Director; and Dr. B. Balaji Nayak, Director of the Digital Agriculture Center. The proposed innovations represent a significant advancement in digitizing agriculture in Telangana. With scientific expertise and policy alignment, PJTAU's roadmap could transform how crop data is recorded, analyzed, and utilized, benefiting both farmers and agricultural planners, according to the participating experts from the university.

Wanaparthy's Bhargavi bags six gold medals
Mahabubnagar: At the 55th convocation ceremony of Professor Jayashankar Telangana State Agricultural University (PJTSAU), held on Sunday, G Bhargavi Chary, a native of Wanaparthy town and daughter of G Yadagiri Chary and Vijay Haimavathi, was awarded six gold medals for her outstanding academic performance. Bhargavi received four gold medals in the overall university category and two more gold medals in the Farm Machinery and Food Processing departments, marking a rare and remarkable achievement. The medals were presented by Jishnu Dev Varma, Governor of Telangana and Chancellor of the University. Speaking at the event, the Governor emphasized that farmers are the backbone of the nation and agriculture is its heart. He said that for the sector to continue thriving, students must innovate and excel in research and new ideas. He proudly noted that India leads globally in crops like pulses, sugarcane, and wheat and has achieved significant milestones in food security. He encouraged students to explore digital agriculture, artificial intelligence, robotics, and IoT to empower farmers and promote awareness through initiatives like AgHub and RAWE (Rural Agricultural Work Experience). The Governor also stressed the importance of recognising the hard work of farmers behind every grain we consume and called on students to remember the deep connection between agriculture and society. He highlighted that agriculture today is not just limited to fields but offers immense opportunities in innovation, digital transformation, and agri-entrepreneurship. The Governor extended congratulations to all medal winners, with special appreciation for Bhargavi for her exceptional feat of securing six gold medals in a single year. He also conveyed congratulations to her parents, recognizing their role in her success.

Agri research crucial for food security: ICAR chief
1 2 Hyderabad: India must invest at least 1% of its agricultural GDP in research and innovation to drive reforms and keep pace with global trends, said Mangilal Jat, the newly appointed director general of the Indian Council of Agricultural Research (ICAR). Speaking at the 55th convocation of Professor Jayashankar Telangana State Agricultural University on Saturday, Jat said that strengthening agricultural research is vital for improving productivity and ensuring food and nutritional security. "Despite being one of the world's largest agricultural producers, India's investment in agri-research remains low. Many countries invest a minimum of 2%; we are lagging behind," he said. He emphasised the need for science-driven innovation that reaches every farmer and called for multidisciplinary research, the establishment of a second gene bank, and greater utilisation of ICT tools and big data. He also underscored the importance of inclusive policies that address gender and social diversity.

"We've promoted practices such as reduced urea use, water conservation, and crop diversification," he said. At the convocation, degrees were awarded to approximately 830 students from the 2021–22 academic year, and around 30 students received gold medals for academic excellence.

How would NISAR expand our understanding of the Earth?
How would NISAR expand our understanding of the Earth? On July 30, the India-US space collaboration crossed a historic milestone with the successful launch of NISAR, or the NASA-ISRO Synthetic Aperture Radar satellite, a flagship earth observation mission jointly developed by the two nations' space programmes. It is the first satellite to use radars of two frequencies — the L-band radar by NASA and the S-band radar by ISRO — to continuously monitor the earth's surface. NISAR is expected to provide unprecedented data on land deformation, ice-sheet dynamics, forest biomass, and natural disasters like earthquakes and floods. With its high-resolution, all-weather, day-night imaging capabilities, NISAR aims to enhance climate resilience, agricultural monitoring, and disaster response. Beyond science, NISAR also holds commercial promise to enable new data services, geospatial analytics, and early-warning systems across sectors such as insurance, infrastructure, and agriculture.
