This investigation aimed to study the effect of organic
fertilizers, nano-fertilizers and salicylic acid on the growth and yield of
rocket (Eruca sativa L.) and the content of active compounds and
antioxidants when the plants were exposed to salt stress. The experiment
was conducted using a randomized complete block design (RCBD)
according to the split-plot system. The main factor was water quality
(1.2 dS m–1 and 8 dS m–1). While the combination treatments of Nano
fertilizer, Salicylic acid and poultry manure were distributed in sub-plots
and each treatment included three replicates. The treatments irrigated with
saline water showed a reduction of glucosinolate and ascorbate contents
(58 μg g–1 and 105.71 μg g–1, respectively). Salinity led to an increase in
glutathione and proline in the leaves (1146 and 2.2 μg g–1, respectively),
while the fertilization treatments (poultry manure + nano-NPK; poultry
manure + salicylic acid + nano-NPK) resulted in an increase in the
glucosinolate content of the leaves under salt stress (85.6 and 89.2 μg g–1,
respectively). The nano-NPK treatment achieved a high value of the
leaves’ ascorbic acid content under the unstressed conditions
(166.73 μg g–1), while the salicylic acid + nano-NPK treatment achieved
the highest value of ascorbic acid under salt stress (137.4 μg g–1). The
combination of salicylic acid + poultry manure + nano-NPK obtained the
highest value of glutathione content in the leaves (1950 μg g–1) under the
stress conditions. There is a positive correlation between salt stress and
glutathione + proline, while the salt stress condition had a negative effect
on glucosinolate, ascorbate and yield.
