A research study was carried out at Agronomy Farm, B. A. College of Agriculture, AAU, Anand, Gujarat, during rabi 2019-20 to study the nitrogen management through organic sources in linseed (Linum usitatissimum L.) under irrigated condition. Different nitrogen management through organic sources viz. 100% RDF (60- 30-0 NPK kg/ha) (T1), N equivalent to 60 kg/ha through FYM (T2), N equivalent to 60 kg/ha through vermicompost (T3), N equivalent to 60 kg/ha through castor cake (T4), N equivalent to 45 kg/ha through FYM + NPK consortium as seed treatment (T5), N equivalent to 45 kg/ha through vermicompost + NPK consortium as seed treatment (T6), N equivalent to 45 kg/ha through castor cake + NPK consortium as seed treatment (T7), N equivalent to 45 kg/ha through FYM + NPK consortium as soil application (T8), N equivalent to 45 kg/ha through vermicompost + NPK consortium as soil application (T9) and N equivalent to 45 kg/ ha through castor cake + NPK consortium as soil application (T10)was laid out in a randomized block design withfour replications. Results of application of N equivalent to 60 kg/ha through vermicompost (T3) significantly influenced the seed yield (1648 kg/ha), straw yield (4819 kg/ha), nitrogen content in seed (3.50%) & straw (0.714%), nitrogen uptake by seed & straw (57.85 & 34.41 kg/ha, respectively), phosphorus uptake by seed & straw (12.20 & 5.11 kg/ha, respectively) and protein content (21.89%) in seed. Phosphorus content in seed & straw and oil content in seed of linseed was remained non-significant with application of different organic sources of nitrogen. Maximum net realization (`85359/ha) was recorded under application of N equivalent to 60 kg/ha through caster cake (T4) and benefit cost ratio (5.89) was recorded under application of 100% RDF (T1).
