This trial aimed to study the separate effects of nano-fertilizers and sugar alcohols in
mitigating salt-stress on eggplant (Solanum melongena L) crop. For this purpose, two different
concentrations of lithovit®-guano25 (A1:0.5 g L
-1
and A2:1 g L
-1
) and sorbitol (B1:5 g L
-1
and
B2:10 g L
-1
) were sprayed on eggplant irrigated by three NaCl solutions (EC1:1.5 dS m-1
,
EC2:3 dS m-1
and EC3 6 dS m-1
). Control plants were salt-stressed without any product. Results
revealed an inhibitory effect of increasing in salt-stress on vegetative traits (plant height, leaf
number, weights of plant parts and root mass fraction), reproductive traits (fruit number, fruit
weight, yield plant-1
, fruit diameter) and photosynthetic pigments. Control plants at EC6 had the
highest cell electrolyte leakage (51.26%). Plant height and fruit number were maximized by A1
at all salinity levels. Additionally, A2 increased fruit weight by 89.98g, 85g and 92.3g compared
to control respectively at 1.5, 3 and 6 dS m-1
. Yield plant-1
increased by this treatment at all EC
levels. At 3 and 6 dS m-1
, A2-treated plants had the highest chlorophyll a (respectively 1.67 and
1.4mg g-1
fresh weight), total chlorophyll (respectively 2.38 and 1.9mg g-1
fresh weight) and
carotenoids (respectively 193 and 172µg g-1
fresh weight) contents. A2-treated plants had the
lowest cell electrolyte leakage at 1.5 dS m-1 (14.27%), 3 dS m-1
(25.31%) and 6 dS m-1 (37.78%).
Treating plants with B1 and B2 maximized respectively fruit diameter at 1.5 dS m -1
and water
content in all plant parts at 3 dS m-1
. Both products helped plants reducing the adverse effects
caused by salinity.
