“The results showed that the treatment of plant compost applied as an organic amendment and 1.5 L ha -1 of biostimulants (VIUSID agro) with foliar application significantly increased seed yield of cultivars, Sakha-4, Sakha-1, and Giza-843 by 17.2, 33.0, and 19.8 % respectively, compared to control under a sandy soil and irrigation water affected by salts.”
