Response of Schefflera Arboricola l. To Gypsum and Sulphur Application Irrigated with Different Levels of Saline Water

A pot experiment was conducted during 2009 and 2010 seasons at National Research Centre, Dokki, Cairo, Egypt,to study the effect of adding gypsum(20gm) and sulphur(20gm) on growth and chemical composition of Schefflera arboricola seedlings grown on sandy soil irrigated with three concentrations of saline water ( 0, 2000 and 4000ppm).Results indicated that saline water application alone led to a significant decrease in all parameters, while those parameters were significantly increased with gypsum or sulphur application under irrigation with normal or saline water up to 4000ppm.The use of saline irrigation water decreased the content of chlorophyll a, b and carotenoids and total carbohydrates as well as N,P,K and S concentration. While, a pronounced increase was noticed for Na, Ca concentration and proline content. On the other hand, all of those above mentioned gave the opposite results with gypsum and sulphur application. The interactive effects between gypsum or sulphur plus salinity levels showed a markedly decrease in Na, Ca concentration and proline content, while chlorophyll a, b and carotenoids and total carbohydrates as well as N,P,K and S concentration increased compared with saline water treatments. It can be concluded that gypsum or sulphur application had decreased the hazard effect of salinity, also, they had a favourable effect on growth and availability of chemical composition to Schefflera arboricola seedlings grown on sandy soil
