Abstract:
An investigation was conducted at. the Agricultural College Farm,
Vellayani to study the effect of graded doses of N and P on nodulation,
protenin and oil content of Asiriya Mwitunde, a newly introduced high yielding
variety of groundnut from Tanganiyaka. The number and weight of nodules
were significantly reduced by, nitrogen at all stages. Whereas phosphorus application
had significantly increased the same at al! levels and stages. Maximum
number and weight of nodules were recorded at the 60th day after sowing,
Protein content of this variety w.i; significantly increased by nitrogen and
phosphorus and a maximum protein content of 29.8 percent was recorded by
the treatment combination 30 kg nitrogen and 100 kg phosphorus per hectare.
The oil content of the crop was significantly reduced by N application while
the same was significantly enhanced by P dressing. The treatment combination
of 10 kg N and 100kg P had recorded the highest oil content of 51.6 per
cent in this variety.
