Abstract

A field experiment on senna comprising three levels of nitrogen (30, 45 and 60 kg ha-1) through three split applications (2, 3 and 4) together with 10 t FYM ha-1, 10 t FYM + 30 kg N ha-1 and control without Nat Delhi, India, showed that FYM at 10 t ha-1 improved the total leaf and pod yield by 38.7 and 45.5%, respectively, over the control. Supplementing it with 30 kg N ha-1 increased the yield further and it was similar to the treatment of 60 kg N ha-1 applied in four splits. This treatment enhanced the yield (leaf and pod) by 24.3%. The total sennosides concentration in the leaves and pods remained unchanged.
