Abstract
This work was conducted at the Nursery of Diarb Negm City Council, SharkiaGovernorate, Egypt during the two consecutive seasons of 2015 and 2016 to study the effect ofdifferent soil salinity levels (0.0, 1500, 3000 and 4500 ppm), lithovit rates (0, 2, 4, 6 and 8 g/l) asfoliar applications and their combination treatments on growth, yield components and some chemicalconstituents of cluster bean (guar) plants. The investigations were performed in a split-plot in completerandomized block design with 3 replications. The obtained results cleared that using salinity levelsdecreased growth parameters (plant height, number of branches /plant and dry weight of leaves/ plant),yield components (pod number and seed yield/plant), some chemical constituents (total chlorophyllcontent a+b) and active ingredient (galactomanan) compared to control. Moreover, the highest valuesin these parameters were registered by lithovit at 8 g/l treatment in both seasons, in most cases.Generally, it could conclude that lithovit at 8 g/l, showed a uniform impact in alleviating of clusterbean growth inhibition and its productivity under moderate salinity stress condition.
