Effect of seed priming treatments on seed quality parameters and storability of field pea (Pisum sativum L.)

Abstract

In order to evaluate the effect of seed priming treatments on seed quality parameters and storability parameters of field pea (Pisum sativum L.) an experiment was conducted in the Seed Testing Laboratory of Department of Seed Science and Technology, C. S. Azad university of Agriculture and Technology, Kanpur during 2015-16 on pea variety KPMR-522 (Jay). The experiment was comprised of ten seed priming treatments viz., T0- Control, T1- Seed priming with Trichoderma harzianum @ 1.5%, T2- Seed priming with Vitavax power @ 0.25% T3- Seed priming with GA3 @ 50 ppm, T4-Seed priming with GA3 @ 50ppm + seed coating with Trichoderma harzianum@ 15g/kg seed,T5 -Seed priming with sodium molybdate @ 500 ppm, T6-Seed priming with sodium molybdate @ 500ppm + seed coating with Trichoderma harzianum @ 15 g/kg seed, T7- Seed priming with leaf extract of Lantana camara @ 10%, T8- Seed priming with water,T9- Seed treatment with Bavistin @ 3g/kg seed. The present investigation revealed that seed priming with sodium molybdate @ 500 ppm + seed coating with T. harzianum @ 15g/ kg seed was significantly improved the seed quality of harvested seeds with percent improvement of 5.75 and 8.00 % in germination, 15.37 and13.73 % in shoot length, 17.03 and 16.05% in seedling dry weight, 13.06 and 17.96 % in seed vigour index-I, 24.50 and 26.90 % in vigour index-II over control during 2015-16.
