Abstract
Growth and mineral distribution of a local
strain of sugar (cyamopsis tetragonoloba
(L.) taub.) were investigated in relation
to salinity. Growth in terms of height and dry matter of different plants parts decreased significantly under salinity. Threshold Ec inducing 50% reduction in seed production was 5.76dS.m-4. Net reproductive effort of the plants treated with 30% sea water was 10.85% , as compared to 27.32% in control . salinity decreased number of pods and seeds per plant , whereas , number of seeds per
pod were unaffected and averaged around 7-8 seeds . distribution of seeds among pods was leptokurtic in all the cases but with salinity variance increased and distribution tended to be more negatively skewed . absorption of Na+
and K + increased with salinity , wheras K+
declined at high salinity . absorption of these ions was almost equal at 20% sea water treatment . Ca-absorption although declined with salinity , Mg++
