An experiment was carried out at Agricultural Research Station, Mannuthy, Kerala to evaluate the effect of nutripriming on tray nursery technique in rice. Nutripriming treatments viz. priming with 0.1% urea, 0.01% borax, 0.05% ZnSO4, combinations of urea with borax and ZnSO4, combination of urea, borax and ZnSO4, 1% Pseudomonas fluorescens and 1% PGPR mix I were applied to seeds grown in seedling trays filled with growing media containing 60% rice husk charcoal + 20% soil + 20% coir pith compost. Combined application of urea, zinc and borax was superior with respect to growth parameters of seedling and mat characteristics. Higher Ca, Mg, S and B uptake was also observed in this treatment. Hence, nutripriming with 0.1% Urea + 0.05% ZnSO4 + 0.01% Borax was found to be a better practice for quality tray nursery production in rice.
