Aim: The study was
conducted to evaluate the response of micronutrient application on herbage
yield and bio active principle of senna for better quality, and thus fetch
higher economic return in domestic and international market.
pot culture experiment was conducted during rainy season (July to September)
to investigate the effects of micronutrient cations such as Zn, Cu, Fe and
manganese (Mn) applications on herbage yield and sennoside content in senna (Cassia
angustifolia). Different doses of micronutrient cations were fixed based
on the initial availability of these micronutrients in soil. Different yield
attributes like the number of flowers and pods and leaves and pods weight per
plant was recorded, while sennoside and micronutrient cations content in leaves
and pods samples were analysed.??
study revealed that a number of flower and pod as well as total fresh and dry
herbage yield (leaf + pod) of senna were improved significantly higher under
the micronutrient treatments. Application of Zn, Cu, Fe and Mn recorded
higher fresh herbage yield up to 207.4, 202.2, 211.3 and 190.4 g plant-1
respectively over the control (173.8 g plant-1). Total sennoside
yield recorded significantly higher 1.93 and 1.93 g plant-1 under
Zn and Fe application, respectively, as compared to control (1.26 g plant-1).
Micronutrient content (Zn and Fe) in senna leaf and pod significantly
increased, while the available micronutrient status in the soil after the
harvesting of the crop also improved. ???
present study revealed that soil application of micronutrient responded
significantly in improving yield and bioactive principle of senna, while
increased the micronutrient content in leaf and pod of senna and available
micronutrient status in the soil.
