Plants that have a lack or deficiency of nitrogen have performance problems and show chlorosis or yellow or light green coloration. They are more prone to pests and diseases. The lack of potassium in the soil also causes the leaves to appear yellowish or blue-green, with dark yellow edges. They are more susceptible to fungal attack. With lack of water, dry soil, the leaves are decayed and also show a yellow hue.

NITI Aayog is partnering with Perlin – a Singapore-based AI start up – to launch the "AI 4 All Global Hackathon." NITI Aayog is inviting developers, students, start-ups and companies to develop AI applications to make significant positive social and economic impact for India. With the vision to further expand the idea of'Artificial Intelligence, AI for All' articulated in the National AI Strategy, NITI Aayog organises hackathons to source sustainable, innovative and technologically-enabled solutions to address various challenges in the development space. The challenge question seeks to develop solutions in Distributed Computing and Privacy Preserving techniques, such as multi-party computation, in AI. The objective of this hackathon is to promote awareness and subsequently develop solutions that deliver the twin benefit of efficient computing to address the infrastructure challenges, while also not compromising on privacy of data for training AI algorithms.
