Assessment of Effect of Nitrogen and Phosphorus Fertilization Module on Growth, Yield and Quality of Linseed (Linum usitatissimum L.)

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.
