Naga-King chilli suffers from poor and erratic seed germination, which affects its production and productivity as seedling germination and growth is a crucial and sensitive stage affecting overall crop yield. Considering the cultivation niches of Naga-King chili i.e. the Northeastern parts of India, which is characterized by eco-friendly and sustainable farming, there is a need to evaluate the natural plant extracts as a priming medium. It is aimed to improve seed germination and seedling growth using naturally occurring plant material without using any synthetic chemical.
