Abstract
The treatments consisted of twelve fertilizer levels viz., control, GRDF (5
t FYM + 50 :75 kg N, P2O5 ha-1 + biofertilizers), 50 per cent RDF + 50 per cent N
through FYM + biofertilizers, 50 per cent RDF + 50 per cent N through vermicompost
+ biofertilizers, 50 per cent RDF + 50 per cent N through neem cake + biofertilizers,
100 per cent N through FYM + biofertilizers, 100 per cent N through vermicompost +
biofertilizers, 100 per cent N through neem cake + biofertilizers, 50 per cent N
through FYM + 50 per cent N through vermicompost + biofertilizers, 50 per cent N
through vermicompost + 50 per cent N through neem cake + biofertilizers, 50 per
cent N through neem cake + 50 per cent N through FYM + biofertilizers and 1/3 N
each through FYM, vermicompost and neem cake + biofertilizers in kharif season as
main plot treatments and three levels of recommended dose of fertilizer (50, 75 and
100 per cent) applied to wheat crop during rabi season as sub-plot treatments.
Among the nutrient management treatments application of
recommended dose of fertilizer (50 kg N + 75 kg P2O5 ha-1) + 5 t FYM ha-1 +
biofertilizers (Rhizobium + PSB) to soybean during kharif season recorded
significantly higher growth and yield attributes and yield of soybean.
The integrated nutrient management treatments showed the higher
protein and oil content in soybean seed than recommended dose of fertilizer through
organic sources alone or in combination.
