Description A field experiment was conducted to evaluate the effect of various
organic and biofertilizers on nutrient uptake, yield, quality and residual
soil nutrient availability in turmeric during kharif 2004-05 at Agricultural
Research Station, Anantharajapet, Kadapa district. The experimental soil
was sandy loam in texture, neutral in reaction, non-saline in nature, low
in organic carbon, available nitrogen and phosphorus and high in
available potassium. The turmeric variety Mydukur was tested in the
experiment. The experiment was laid out in a randomized block design
with twelve treatments consisting of four types of organic manures i.e.
FYM (Farm Yard Manure), VC (Vermicompost), NC (Neem Cake) and
DGLM (Decomposed Green Leaf Manure) and their combinations i.e.
FYM + VC (50:50), FYM + NC (50:50), FYM + DGLM (50:50) and
FYM + VC + NC + DGLM (25 : 25 : 25 : 25) and three treatments of biofertilizers
combined with FYM i.e. FYM + Azospirillum, FYM +
Phosphobacteria and FYM + VAM and control with recommended doses
of fertilizers (RDF) i.e. 180-60-120 kg ha-1 of N, P and K.
Application of different organic fertilizers significantly improved
the soil properties viz. organic carbon and BD (Bulk Density). However,
there was no significant change in pH and EC. Similarly, the soil
properties improved with their combinations and with biofertilizers. The
treatment FYM + VC (T5) has registered the maximum organic carbon
content and the lowest bulk density, closely followed by FYM +
Phosphobacteria (T10) and FYM + NC (T6) and FYM + VC + NC +
DGLM (T8) which were comparable among them. The treatment RDF
(T12) has recorded the lowest organic carbon content and the highest bulk
density.
The residual soil nutrient availability of major (N, P and K),
secondary (Ca, Mg and S) and DTPA extractable cationic micronutrients
(Fe, Cu, Mn and Zn) was significantly influenced by different treatments.
Among the treatments, FYM + VC (T5) has recorded the highest closely
followed by FYM + Phosphobacteria (T10), FYM + NC (T6) and FYM +
VC + NC + DGLM (T8) which were on par with each other, while
DGLM alone (T4) has recorded the lowest residual soil nutrient
availability.
Leaf nutrient concentration at 110 DAP (Days after planting) was
significantly influenced by different treatments. Of all the treatments
RDF (T12) has recorded the highest leaf nutrient concentration of major,
secondary and cationic micronutrients which was closely followed by
FYM + VC (T5), FYM + Phosphobacteria (T10), FYM + NC (T6) and
FYM + VC + NC + DGLM (T8) which were on par with each other,
while DGLM alone (T4) has registered the lowest leaf nutrient
concentration at 110 DAP.
The nutrient uptake of major (N, P and K), secondary (Ca, Mg and
S) and micronutrients (Fe, Cu, Mn and Zn) was significantly influenced
by different treatments. The treatment RDF (T12) registered the
maximum nutrient uptake, closely followed by FYM + VC (T5), FYM +
NC (T6) and FYM + VC + NC + DGLM (T8) which were on par with
each other, while, the treatment DGLM alone (T4) has recorded the
lowest nutrient uptake.
The yield attributes viz., number of rhizomes, finger rhizome
length (cm), finger rhizome girth (cm), mother rhizome length (cm) and
mother rhizome girth (cm) were significantly influenced by different
treatments. Among the treatments, RDF (T12) registered the maximum
values, closely followed by FYM + VC (T5), FYM + Phosphobacteria
(T10), FYM + NC (T6) and FYM + VC + NC + DGLM (T8) which were
on par with each other. Application of DGLM alone (T4) recorded the
lowest values.
Fresh and cured rhizome yields (t ha-1) were significantly
influenced by different treatments. Of the treatments RDF (T12)
registered the highest yield closely followed by FYM + VC (T5), FYM +
Phosphobacteria (T10), FYM + NC (T6) and FYM + VC + NC + DGLM
(T8) which were on par with each other, while the treatment DGLM alone
(T4) registered the lowest yield.
The quality parameter i.e., curcumin content (%) was significantly
influenced by different treatments. Among the treatments, FYM + VC
(T5) has recorded the highest curcumin content (%) which was closely
followed by FYM + Phosphobacteria (T10), FYM + NC (T6), FYM + VC
+ NC + DGLM (T8) and RDF (T12) which were on par with each other,
while the treatment DGLM alone (T4) registered the lowest.
The application of biofertilizers in combination with FYM was not
significantly influenced the nutrient uptake and yield of turmeric.
However, FYM + Phosphobacteria (T10) has recorded maximum values,
which was on par with other two treatments viz., FYM + Azospirillum
(T9) and FYM + VAM (T11).
