Effect of nutripriming treatments on growth parameters of riceseedlings in nursery tray

Abstract

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 154 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.

Boron seed treatments induce germination and seedling growth by reducing seed-borne pathogens in safflower ( Carthamus tinctorius L.)

“…have been employed to promote seed germination and vigor (Pallaoro et al 2016;Waqas et al 2019). In recent years, minor plant nutrients have been used as seed priming agents (nutripriming) to enhance the germination and seedling growth of wheat (Iqbal et al 2017), maize (Muhammad et al 2015;Rasool et al 2019), rice (Farooq et al 2018), bean (Majda et al 2019), and rice (Ancy et al 2022). One of the key micronutrients required for priming agents is boron (B), which plays a crucial role in the construction and stability of cell walls and has a positive impact on reducing disease severity (Picanço et al 2021).…”

“…Several grades of perlite, pine bark, and peat moss have been evaluated as soilless growing media by [23] and found that coarse-grade perlite produced more commercially viable cucumber fruit compared to medium-grade perlite. Application of composted organic waste and biochar enhanced plant growth attributes and nutrient contents compared to peat media [24].…”
