Description Field experiment was conducted during 2004 on sandy
loam soils of orchard block in Agricultural College Farm, Bapatla
to study the effect of organic manures on growth, yield and
nutrient uptake of senna. Three kinds of organic manures in
combination with biofertilizers were tested in comparison with
inorganic fertilizer and control in randomized black design with
three replications.
Application of organic manures like FYM, vermicompost
and neem cake along with biofertilizer (Azospirillum + PSB)
showed increase in growth parameters viz., plant height, number
of branches per plant, number of leaves, drymatter production
and crop growth rate, when compared to their combination with
Inorganic fertilizer (P and K) and control. However, inorganic
fertilizer found superior of all these parameters after second split
of 50% nitrogen application. Same time vermicompost +
Azospirillum + PSB, was on par with inorganic treatment.
Application of vermicompost + Azospirillum + PSB and
inorganic fertilizer were found to reduce the number of days taken
for 50% flowering and also increased number of inflorescence.
There was significant increase in dry leaves and pod yield
by vermicompost + Azospirillum + PSB at first harvest, but it was
on par with inorganic fertilizer treatment during second and third
harvests. There was no significant difference among the
treatments regarding sennoside content in leaves and pods.
Plant received inorganic fertilizers removed higher
nutrients like N, P and K from the soil, which was on par with
vermicompost + Azospirillum + PSB. Regarding nutrient content
in plant, potassium content alone found non significant.
Correlation studies revealed that the yield of senna had
significant positive correlation with plant height, number of
branches, number of leaves, number of pods NP contents,
chlorophyll content and sennoside content in pods.
Economics of cultivation indicates that the crop is
economically viable even without fertilizer application.
