| Abstract: | Summary Application of FYM caused a gradual increase in the dry weight of dhaincha (Sesbania aculeata Pers.) tops. It also caused a gradual increase in the content of Mg and K and a decrease in the content of Ca, Na, N and
P in dhaincha tops. Increase in Ca: Na ratio was more steeper than (Ca+Mg): (Na+K) ratio. Total uptake of Ca, Mg, K, N and
P increased and that of Na decreased in response to FYM. Contribution of Ca from Ca45CO3 did not differ much at different levels of FYM and it was less than 6 per cent of total Ca in plant tops in all the treatments.
