Standardization of seed biopriming with actinobacteria for seedling vigour in peanut (Arachis hypogaea L.)

Abstract

Bio priming: The interaction of different strains of the same bio agent (organism) with different crop species differ greatly, so screening of different isolates for plant growth promoting traits is a key factor of consideration for successful bio priming. To study the effect of biopriming duration on seed, peanut seeds were bioprimed with actinobacteria for 2, 4 and 6 hr. The seed biopriming of 2hr duration was found to be best as it increased root length, shoot length and dry biomass seedling vigour.
