Abstract
Quantity of nitrogen and phosphorus assessed for growth, yield and quality of linseed during rabi 2022-23 at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, S.D.A.U., Sardarkrushinagar. Nine treatment combinations comprising nitrogen (40, 60 and 80 kg N/ha) and phosphorus (30, 40 and 50 kg P2O5/ha) were tested in FRBD and replicated thrice in loamy sand. Significantly higher plant height, branches/plant, capsules/plant, test weight, seed yield (1540 kg/ha), stover yield (2330 kg/ha), oil content in seed, nitrogen (content and uptake), phosphorus uptake by linseed were recorded under 80 kg N/ha. The same treatment gave maximum net realization (Rs.61716/ha) and BCR (2.51). Significantly higher plant height, branches/plant, capsules/plant, test weight, seed yield (1524 kg/ha), stover yield (2297 kg/ha), oil content in seed, nitrogen uptake, phosphorus (content and uptake) by seed and stover recorded under 50 kg P2O5/ha. The same treatment gave maximum net realization (Rs. 59941/ha) and BCR (2.45). Application of 80 kg N/ha and 50 kg P2O5/ha were at par with 60 kg N/ha and 40 kg P2O5/ha, respectively. Based on the result of one year experimentation, it is concluded that to achieve better growth, yield and quality of linseed, it should be fertilized with 60 kg N/ha and 40 kg P2O5/ha.
