Abstract EN
: Two field experiments were carried out during the two successive summerseasons of 2019 and 2020 in the private Farm at Keshek Village, Abou- Hamad district, Shahrkia Governorate, to study the effect ofpotassiumrates(45, 60, 75 and 90 kg K2O/fad.
) assoil applicationsand differentsources ofpotassium, i.
e.
potassium citrate (K₃C₆H₅O₇) at 1 ml/l, potassium humate (C9H8K2O4) at 3 g/l, potassium thiosulfate (K2S2O3) at1ml/l andpotassium silicate (K₂SiO₃)at 3 ml/l, besidesprayed with water (control treatment)asfoliar application on dry weight, mineral uptake andyieldand its componentsofeggplant (cv.
long black).
The interaction between K2O at 90 kg/fad.
and foliar spray with K₃C₆H₅O₇at 1 ml/lsignificantly increaseddry weight ofbranches, leaves and shoots/plant, N, P and K uptakeby shoots, average fruit weight, yield/plant, andtotal yieldwith no significant differences with K2O at 75 kg /fad.
, and spraying with K₃C₆H₅O₇at 1 ml/l, followed by theinteraction between90 kg K2O/fad.
, and spraying withpotassiumhumateat 3g/linboth seasons.
In the same time, total yield /fad.
(14.649 and 14.768 ton/fad.
)produced from75 kgK2O and spraying with K₃C₆H₅O₇at 1 ml/l treatmentwere more than total yield/fad.
(12.320 and 12.290 ton/fad.
)produced from90 kg K2O and unsprayed (spraying with water)in the 1st and 2nd seasons, respectively.
As forpotassium use efficiency(KUE), the highest values of KUE wererecorded withthe interaction between 45 kg K2O/fad.
and K₃C₆H₅O₇at 1 ml/lfoliar spray (245.3 and 247.2 kgfruit/kgK2O) in the 1st and 2nd seasons, respectively
