Abstract
The aim of this study is to determine the role of different organic manures viz. raw cattle dung, poultry waste and vermicompost on the growth of V. spiralis in the container in open and shadow environmental condition. Experiment was conducted to study the role of different organic manures viz. cattle manure, poultry manure and vermicompost on the growth of V. spiralis in 100 g capacity pot for 28 days. All the manures were applied at the rate of 2 g pot -1 . Significant difference was not found among the treatments for water parameters, while significant difference was observed for nutrients of soil. Plastic pools manured with poultry and cattle manure did not show significant difference for final biomass, total length, number of leaf and runners of V. spiralis . It was concluded that the application of cattle manure with soil increase biomass, total length and produced good leaf quality of V. spiralis .
Highlights
Aquatic plants refer to any organism living in water that photosynthesize and complete part or all of their life cycle in or near the water
Submerged aquatic plants can increase the transparency of water through withholding suspended solids, thereby improving water quality of shallow lakes and ecosystem stability [4]
Aquatic freshwater plant V. spiralis was obtained from Local aquarium shop (Ratnagiri)
Summary
Aquatic plants refer to any organism living in water that photosynthesize and complete part or all of their life cycle in or near the water. Aquatic plants provide food, shed, shelter and breeding places to fishes [1,2] and absorb many harmful nutrients and pollutants from water, as a buffer strip. They can significantly impact the assimilation of pollutants such as nitrogen and phosphorus from water by biological absorption or physicochemical adsorption [3,4]. Submerged aquatic plants can increase the transparency of water through withholding suspended solids, thereby improving water quality of shallow lakes and ecosystem stability [4]. V. spiralis, a beautiful submerged aquatic plant with conspicuous transverse darker bands on leaves. The plant has runners to the base through which vegetative propagation takes place [5]
