Plant growth-promoting microorganisms as natural stimulators of nitrogen uptake in citrus
Improving nitrogen uptake efficiency by citrus in Mediterranean areas, where this crop predominates, is crucial for reducing ground-water pollution and enhancing environmental sustainability. This aligns with the Farm to Fork Strategy (European Green Deal) objectives, which aim to reduce the use...

| description | Improving nitrogen uptake efficiency by citrus in Mediterranean areas, where this crop predominates,
is crucial for reducing ground-water pollution and enhancing environmental sustainability.
This aligns with the Farm to Fork Strategy (European Green Deal) objectives,
which aim to reduce the use of mineral fertilizers by up to 20% and to eliminate soil contamination
from nitrogen entirely. In this context, exploring the potential of plant growth-promoting
bacteria application to reduce nutrient inputs is a promising opportunity. The objective of
the present study was to evaluate the effect of two Bacillus subtilis strains either individually
inoculated or in combination with Saccharomyces cerevisiae on 15N-labeled fertilizer uptake
efficiency and physiological parameters. Individual inoculations positively affected tree
water potential, leaf chlorophyll concentrations (SPAD-values) and photosynthetic performance,
enhancing tree growth. Fertilizer-15N use efficiency increased, as did phosphorus
and potassium uptakes. Conversely, no response was observed in the trees co-inoculated
with S cerevisiae. Therefore, PGPB can be considered an interesting means to reduce reliance
on synthetic fertilizers in citrus orchards, minimizing the environmental impact and promoting
sustainable production practices. |
