Abstract
A field experiment was carried out during the period 2092007-2022008 in the Experimental Farm of the Faculty of Agriculture at Shambat to investigate the response of Senna plant (Cassia senna L.) to organic, mineral and microbial fertilization.
Generally, the soil of the experimental site is non saline, non sodic and not expected to impose adverse impact on growth and development of Senna plant.
The application of almost all combination treatments consisting of chicken manure and biofertilizer substantially contributed to promoting production of green biomass increasing Senna plant vegetative growth parameters. The super phosphate applied in a single dose provided progressive increase in dry weight of plant, number and dry weight of pods. The super phosphate once being combined with urea reduced the plant dry weight.
The combination treatments (CM4+ Bio), (CM3+Bio) provided the highest increase in the contents of sennosides A and B in leaves as well as in pods, while super phosphate applied in a single dose or in combination recorded very low contents. The control almost invariably revealed the lowest values among all combination treatments including organic and inorganic fertilizers.
The study recommended application of organic manure combined with biofertilizer for the production of dry biomass, plant growth and yield parameters. For provision of sennosides A and B in leaves, super phosphate in a single dose or in combination could be avoided.
Key words: Senna plant, Biofertilizer, Organic Fertilizers, Mineral Fertilizers, Sennosides.
