Abstract

Among the different chemicals used in pre-sowing treatment, the maximum augmentation on seed quality attributes in terms of germination and vigour was obtained with potassium nitrate. Pre-soaking seed treatment with 0.75% potassium nitrate for 16 h. was found to improve germination (89.5%) and vigour potential in terms of root and shoot length, dry matter production and vigour index.
