Effect of Npk on Growth, Seed Yield and Quality of Radish Cv. Pusa Rashmi Grown in the Calcareous Soils of North Bihar

A field experiment on radish cultivar ‘Pusa Rashmi’ was conducted at Rajendra Agricultural University Pusa, Bihar, during 1981–1983. Soil application of three levels of nitrogen, phosphorus and potash each at 0, 40 and 80 kg/ha were evaluated. Nitrogen did not show significant effect in increasing the height, number of main branches and 100 seed weight, however, phosphorus increased the height of plant significantly. Increased doses of potash reduced the height and number of main branches. The seed yield increased with increasing doses of nitrogen and phosphorus but potash beyond 40 kg/ha did not show and significant effect in increasing seed yield. The interaction of NFP had significant effect on height a.id number of main branches, however, N K affected only number of main branches. The seed yield was significantly increased through all first order interactions viz., NP, NK and PK. The maximum seed yield was recorded at 80 kg N, 80 kg P₂O₅ and 40 kg K₂O/ha application.
