    Effect of nitrogen and phosphorus on asiriya mwitunde groundnut in Kerala
    (Kerala Agricultural University, 1975) Jayadevan, R; Sreedharan, C
    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.

    Effect of nitrogen and phosphorus on asiriya mwitunde groundnut in Kerala
    (Kerala Agricultural University, 1975) Jayadevan, R; Sreedharan, C
    An experiment was conducted to assess the high fertilizer responsiveness of Asiriya Mwitunde, a groundnut variety introduced from Tanganiyaka in respect of N and P under the soil and climatic conditions of Kerala. The various growth characters such as height, leaf and haulm production were significantly increased by 30 kg N/ha. Application of P upto 100 kg/ha increased significantly the yield attributes such as weight of kernels, test weight, shelling percentage in this variety. Pod yield was significantly increased by 20 kg N and 75 kg P giving a per hectare yield of about 2969 kg/ha under the agro-climatic conditions of Kerala.
