plant extracts and chlorine (CaOCl2+ CaCO3). CCC alone decreased seedling growth and
vigour index. Field emergence was highest with 1% leaf extract of each of pungam
[Pongamia pinnata] and Prosopis. Seed germination and vigour index were highest from this
treatment plus chlorine. The combined treatment also gave the highest vigour and seedling
growth following accelerated aging.

Abstract
Precleaned cotton seeds were treated with various combinations of KCl, CCC [chlormequat], plant extracts and chlorine (CaOCl2 + CaCO3). CCC alone decreased seedling growth and vigour index. Field emergence was highest with 1% leaf extract of each of pungam [Pongamia pinnata] and Prosopis. Seed germination and vigour index were highest from this treatment plus chlorine. The combined treatment also gave the highest vigour and seedling growth following accelerated aging.
