experiment was conducted at private farm located at Sanor village, Beni Suif Governorate (120 k southern Cairo city), Egypt. The main target of this study was examining the effect of spraying salicylic acid (SA) at 100, 200,300 and 400 ppm every concentration was applied once, twice and three times plus the control treatment on growth, seed yield guaran contents and nutritional status of guar plant grown in sandy soil under Beni Sueif Governorate conditions. Increasing SA concentration resulted in a gradual and significant promotion in all vegetative growth characteristics and seeds yield/plant and seeds yield/feddan. In addition, the guaran production remarkably and significantly increased in response of SA treatment. However, no significant differences were observed between the two highest concentrations (300 and 400 ppm of SA) as well as between the two or three frequencies. Guaran yield per plant as well as per feddan remarkably enhanced as a result of spraying SA, this increment was parallel with increasing the concentrations and number of applications. Spraying SA at 100 to 400 ppm once, twice and thrice times considerably improved leaf chlorophylls content and carotenoids contents as well as leaf N, P, K and Mg % of guar plants over the control treatment. Generally, the positive effect of SA was in proportional to the increase the frequencies of application from one to three times.
