Abstract

Aim: To determine the ideal concentration of each priming agent among several selected concentrations which could produce robust paddy seedlings under laboratory conditions.

Place of Study: The present investigation was carried out at College farm, Agricultural College, Bapatla.

Methodology: Certain seedling vigour traits such as germination percentage, shoot length, root length, seedling length, seedling dry weight, seedling vigour index-I & II were recorded and analysed using crompletely randomized block design (CRD). Best concentration is the one with higher vigour indices.

Result: The results revealed that, 1% Nacl, 40 ppm ascorbic acid, 150 ppm gibberellic acid, 2 % neem leaf extracts, 0.5 & 0.1 % P & Zn were optimum concentrations under each priming technique. When compared among all the techniques, priming with gibberellic acid @ 150 ppm performed better in terms of all the vigour traits.

Keywords: Hormonal priming, paddy, seed invigoration, seed priming techniques
