ABSTRACT
The studies conducted with improved seed management practices are required to exploit the storability of maize. The maize COHM 5 seeds were primed with biofertilizer (20% Azospirillum, 20% Phospho bateria) and biocontrol (80% Pseudomonas fluorescens and 80% Tricoderma viride) along with hydro priming and control. Storage studies on evaluation of seeds primed with talc based biocontrol agent and liquid form of humic acid and biofertilizer revealed that seed primed with 20 per cent humic acid with the seed to solution ratio of 1:2 for 12h and stored in moisture vapour container preserved the viability for longer time recording 91 per cent germination after 9 months and 75 per cent germination after 15 months along with higher seedling and biochemical vigour characters.
Key words :
Bioagents, Bio-fertilizers, Humic acid, Maize hybrid, Seed treatment, Seed longevity.
