Abstract
To investigate the effect of irrigation intervals and foilar application of salicylic
rates on growth, productivity and grain protein content of wheat (Shandweel-1), in this
respect two field experiments were conducted out at the Experimental Farm, Faculty of
Agriculture (Saba Basha), Alexandria University, Egypt during the two seasons of
2018/2019 and 2019/2020.
The precceding crop was maize in the two seasons.
This experiment was laid out in split plot design in three replications.The main
plots was irrigation treatments (normal irrigation, skipping the first irrigation, skipping
the second irrigation and skipping the third irrigation), while salicylic acid (SA)
concentration (water = control, 1 mM; 2 mM and 3 mM/L) distributed at random in sub
plot.
In both 2018/2019 and 2019/2020, wheat grains at the rate of 168 kg/ha were sown
by broadcasting method in 15th and 10th November in 2018/2019 and 2019/2020 seasons,
respectively. The area of sub plot was 10.50 m2
(3.50 m long and 3.00 m width).
The commercial salicylic acid (SA) from El Jomhoureya Company – Cairo- Egypt
were prepared in concentrations as mentioned before and sprayed during at 50 and 70
days after sowing the growing seasons.
Phosphorus fertilizer was added at rate of 60 kg P2O5/ha in form as calcium super
phosphate applied with soil perpartion. Mineral nitrogen fertilizer at 168 kg N/ha was in
the form of urea (46 % N) applied at two doses the first dose was 112 kg N/ha applied
with the first irrigation while the second dose was 56 kg N/ha applied with the second
irrigation and K fertilizer was added at rate of 60 kg K2O/ha in form potassium sulphate
applied soil perpration and all the other cultural practices were followed as Ministry of
Agriculture and Land Reclamation recommendations.
All the other cultural practices were followed as Ministry of Agriculture and Land
Reclamation recommendations.
