Abstract:
A field experiment was conducted on rice during rabi season of 2015 to
study the effect of balanced nutrient management in nutrient availability,
yield, uptake, protein and oil content in niger. The experiment was
conducted using five levels of potassium viz., 0, 20, 40, 60 and 80 kg ha-1
,
four levels of sulphur viz., 0, 15, 30 and 45 kg ha-1
, four levels of zinc viz.,
0, 2, 4 and 6 kg ha-1
, four levels of Boron viz., 0, 0.5, 1.0 and 1.5 kg ha-1
and nitrogen in a single dose @ 40 kg ha-1
using niger as the test crop.
Stover and seed yield was increased with increasing application of sulphur.
The highest seed yield (4.69 q ha-1
) was recorded with application of
highest doses of sulphur. Oil content of niger varied from 31.7% to 38.8%.
Sulphur application also increased oil content. Protein content ranged
between 15.05 to 21.12%. Both micronutrients and sulphur application
resulted in increase in protein content in niger seeds.
