Summary

Application of gypsum (tagged Ca45SO4.2H2O) caused a considerable increase in dry matter yield and content of Ca, Ca45, Mg and K and Ca:Na and (Ca+Mg): (Na+K) ratios and a decrease in the content of Na, N and P in dhaincha tops. There was a considerable increase in the total uptake of Ca, Mg, Na, K, N, P and Ca45 by plant tops in response to gypsum. Contribution of Ca from applied Ca45SO4 varied from 78.3 to 84.7 per cent of the total Ca in plant tops, whereas, its uptake from this source varied from 52.18 to 98.73 me per 100 g plant tops. re]19720705
