Effect of Nitrogen and Sulphur Levels on Growth and Yield of Linseed (Linum usitatissimum) Under Rainfed Condition of Nagaland

Abstract

Background: Linseed is an annual herbaceous plant belonging to the family of Linaceae, having well developed fibrous root system with several lateral roots. It has been grown since ancient times for fibre (flax) and seed, which is rich in oil. The crop has narrow leaves and alternate with shiny yellow or light brown colored seeds. The current investigation was carried out to determine the suitable level of nitrogen and sulphur and their interaction effect on growth and yield of linseed.Methods: A field study was conducted in the experimental site of SASRD, NU during the rabi season with four levels of nitrogen (0,20,40 and 60 kg ha-1) and sulphur (0,20,40 and 60 kg-1) under three replications following RBD, five random plants were tagged from each plot for field observation.Conclusion: Application of 60 kg N ha-1 resulted in highest plant height, number of branches plant-1, bolls plant-1, seed (799.87 kg ha-1) and stover yields (1619.87 kg ha-1), similarly, incorporation of 40 kg S ha-1 recorded significantly higher plant height, number of branches plant-1, bolls plant-1, seed boll-1, yield (797.54 kg ha-1) and stover yields (1557.58 kg ha-1). The combination of 60 kg N and 40 kg S recorded highest plant height, number of branches plant-1, bolls plant-1, seeds boll-1, seed weight plant-1, seed (840.72 kg ha-1) and stover yields (1713.3 kg ha-1)
