Governorate, Egypt during the two consecutive seasons of 2015 and 2016 to study the effect of different soil salinity levels (0.0, 1500, 3000 and 4500 ppm), lithovit rates (0, 2, 4, 6 and 8 g/l) as foliar applications and their combination treatments on growth, yield components and some chemical constituents of cluster bean (guar) plants. The investigations were performed in a split-plot in complete randomized block design with 3 replications. The obtained results cleared that using salinity levels decreased 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 chlorophyll content a+b) and active ingredient (galactomanan) compared to control. Moreover, the highest values in 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 cluster bean growth inhibition and its productivity under moderate salinity stress condition.
