Abstract
A field experiment was conducted at the Agricultural Research Station,
Kathalagere (Davanagere District, Karnataka) during rabi, 2010 to study the effect of
FYM and biodigester liquid manure (BDLM) on growth and yield of irrigated sunflower
and soil nutrient status after harvest of the crop. The experiment consisted of 14
treatments involving combination of different levels of FYM (5.0, 7.5 and 10.0 t ha-1) and
BDLM equivalent to 40, 60, 80 and 100 kg N ha-1 along with recommended FYM +
recommended dose of fertilizers (RDF) and RDF alone. The experiment was laid out in
randomized completely block design with three replications. The application of FYM at
10 t + BDLM equivalent to 100 kg N ha-1 recorded significantly higher achene yield of
sunflower (2333 kg ha-1), oil content (39.37 %), oil yield (918.57 kg ha-1), uptake of N, P,
K by sunflower (118.52, 23.84 and 111.84 kg ha-1, respectively), net returns (` 42829
ha-1) and B:C ratio (3.40) than application of RDF alone (1108 kg ha-1 achene yield,
31.44 % oil content, 348.4 kg ha-1 oil yield, uptake of 56.77 kg N, 6.78 kg P and 45.49 kg
K ha-1, ` 18701 ha-1 net returns with B:C ratio of 2.85), but was on par with application
of FYM at 7.5 t + BDLM equivalent to 100 kg N ha-1 and FYM at 7.5 t ha-1 + RDF.
Availability of N, P and K in the soil after harvest of sunflower was lower with the
application of RDF alone. Significantly higher soil bacterial, fungal and actinomycetes
population were observed with application of FYM at 10 t + BDLM equivalent to 100 kg
N ha-1 than with application of RDF alone.
