Amaranthus is a vegetable rich in dietary fibre, protein, minerals, and antioxidants. Theheavy demands of nutrients are often met through chemical fertilizers and its prolonged usage can result innutrient imbalances, soil degradation, and environmental pollution. Application of liquid organic manureslike panchagavya, vermiwash, fish amino acid and egg amino acid can enhance productivity withoutdeteriorating soil health. A study was conducted at College of Agriculture Vellayani, Kerala, India, tounderstand the influence of liquid manures on growth and yield of leafy vegetable amaranthus. Thesemanures were applied 15 days after transplanting and continued till harvesting at weekly intervals.Panchagavya spray at a rate of one per cent at weekly intervals recorded maximum height, number ofleaves and girth. The highest fresh weight and dry weight were noticed in panchagavya and vermiwashtreated plants. Liquid manures can offer sound and sustainable agricultural practices by reducing thedependence on chemical fertiliser.
