Abstract
Seed priming is one of the most important developments to help rapid and uniform germination and emergence of seeds and to increase seed tolerance to adverse environmental conditions. The study aims to investigate the effect of sowing windows and seed invigoration treatments on Physiological Traits of soybean (Glycine max L. Merrill). The study was carried out at the Seed Technology Research Unit, Dr. PDKV, Akola (MS), in late kharif 2021–2022, by using factorial randomised block design with eight (8) treatments, two (2) sowing windows and three (3) replications. The dates for sowing are (i) August 15, 2021 and (ii) September 1, 2021. The treatments with the highest values of plant height, leaf area, leaf area index, dry matter production, Relative Growth Rate (RGR), and Net Assimilation Rate (NAR) were (T6) NPK capsule Hydropriming and (T8) KNO3 1% Hydropriming. While the days to 50% flowering were lowest in T6-NPK capsule Hydropriming. The interaction effect between different sowing windows and seed invigoration treatments was found nonsignificant with respect net assimilation rate of soybean. In comparison to the control, other priming treatments were also found to be significant. The research is helpful to researchers to find the right seed invigorating treatment to get better physiological traits.
