Abstract
A pot experiment was conducted during 2009 and 2010 seasons in the National Research Centre, Dokki, Giza, Egypt (Research and Production Station, Nubaria). The aim of this work was to study the effect of Nile compost application at rats of (0, 100 and 200g/pot) on growth and chemical constituents of Jatropha curcas under three levels of salinity of diluted sea water (2000, 4000 and 6000 mgL -1 ) and tap water served as control. Salinity treatments have a depressing effect on various growth parameters (i.e. plant height, stem diameter, root length, leaves number/ plant, leaf area and fresh and dry weight of all plant organs. The same tendency was observed regarding chlorophyll a, b, carotenoids content and total carbohydrate percentage as well as the percentage of N, P and K. Such depressive effect was increasingly prominent with increasing salinity level. On the other hand, proline content and percentage of Na increased by increasing salinity levels. This means that, all previous growth parameters and chemical constituents, except the percentage of Na and proline content, tended to increase by increasing the rates of Nile compost up to 200g as compared to the untreated ones. Hence, it could be recommended to treat plants, grown in regions irrigated with saline water, with Nile compost to overcome destructive effect of salinity.
