The experiment was undertaken to understand the effect of different levels of nitrogen and sulphur application on growth attributes, yield attributes and seed quality parameters in two varieties of linseed. The experiment was laid out in a factorial randomized block design with two replications. There was eighteen treatment combinations in thirty six plots consisting of two varieties viz. LSL-93 (V1) and NL-260 (V2) , three levels of nitrogen viz. N1@ 0 kg/ha; N2@ 40 kg/ha and N3@ 60 kg/ha, three levels of sulphur viz. S1@ 0 kg/ha; S2@ 25 kg/ha and S3@ 50 kg/ha. The sowing was done on 25 November 2021 by line sowing. The fertilizers were applied according to the treatments before sowing. The results indicated that the growth and yield attributing characters of linseed viz. number of branches plant-1, number of capsules plant-1, number of seeds per capsule, seed yield plant-1, test weight (g) were appreciably more in the variety LSL-93 (V1) except for plant height which was higher in the other variety NL-260 (V2). The variety LSL– 93 (V1) was found to be significantly more effective in producing higher seed yield, oil yield and protein content over the variety NL– 260 (V2). Among the different levels of nitrogen, application of N@ 60 kg/ha i.e (N3) was found to be most effective for improving the growth, productivity and protein content of linseed, whereas among the different sulphur levels, S@ 50 kg/ha i.e (S3) showed better results w.r.t oil yield compared to the other levels of sulphur. Among the treatment combinations V1N3S3 (LSL-93:N60:S50) was found to be the most effective treatment compared to the rest of the treatment combinations.EnglishThesis
