Effect of soil mulch and fertilizers on alleviating of salt stress of chlorophyll, leaf area and hormones content of broccoli plants : (Brassica oleracea var. Italica)‎

الملخص EN

-Factorial field experiments was conducted during 2012/2013 growth season to study the effect of soil mulch (mulch and without mulch) and some fertilizers (control , sulfur, organic and high potash fertilizer) on alleviating salt stress in leaf area, chlorophyll and free and bound hormones (IAA, GA3, ABA and Zeatine) of broccoli.

The results showed that using mulch, fertilizer treatment and the interaction between mulch and fertilizer treatment led to a significant increase in leaf area and chlorophyll content.

In general, using mulch+ fertilizers, which caused increases in free and bound hormones (IAA, GA3 and Zeatine) and decrease in ABA and to less extend by using mulch without fertilizer
