Evaluating relative efficacy of different priming treatments in brinjal (<em>Solanum</em> <em>melongena</em> L.)

Abstract

The present experiment was conducted in a CRD with three replications to study the effect of different priming agents in improving the seed quality parameters in brinjal. Seeds of four brinjal varieties were treated with GA3 (1 ppm), KNO3 (5%), Na2HPO4 (2%), PEG (10%), ZnSO4 (1%), Ascorbic Acid (50 ppm) and deionised H2O for 24 hours and then dried to original moisture content under shade. Dry seeds were taken as control. Data were recorded on germination (%), seedling vigour index-I & II in both lab and field conditions. The results revealed that GA3 ranked first in increasing germination percent, SV-I and field emergence percent (FEP) as compared to control; KNO3 ranked first in increasing SV-II and of SV-I of seedling emerged in the field as compared to control; and ZnSO4 ranked first in increasing SV-II of seedling emerged in the field as compared to control.
