Patil P. D., Darade Arya M. and Darade M. S.*

ABSTRACT

The aqueous extract of Pistia stratiotes affects on growth parameters of Arachis hypogaea. The leaf extract of Pistia was prepared into different concentrations like 1 %, 2 %, 4 % and 6 %. The experiment was conducted on groundnut variety called as Mahabeej. The seeds of groundnut were soaked in extract of pistia for one hour. The maximum seed germination (100 %) was recorded in 1 % over the control. The minimum seed germination (46.66 %) was noted in 6 %. The maximum seedling height (12.48 cm) was noted in 1 % and minimum height (4.13 cm) in 6 % concentration. The maximum root length (5.14 cm) was recorded in 1 %. The shoot length (7.34 cm) noted in 1 % concentration. The biomass increase is observed in 1 % concentration of extract over the control. The fresh weight of seedling was recorded maximum (1.78 gm ) in 1 % concentration. The decrease in dry weight (0.146gm) was recorded in 6 %. The maximum (336.2 gm) vigour of seedlings recorded in control. It is observed that as concentration increases then there is decrease in growth parameters. The increase in concentration becomes inhibitory for growth of groundnut.
