Abstract:

A research work was conducted at the experimental field of SCS College of Agriculture, Assam Agricultural University, Dhubri, Assam during Rabi season of 2019-2020 to study the “effect of soil and foliar fertilization of nitrogen on morpho-physiological, growth characters and seed yield of rapeseed variety TS-46. The experiment comprised of ten treatments. Results revealed that there were significant differences among the treatments in terms of total leaf chlorophyll content, leaf area per plant, specific leaf weight (SLW), plant height, number of branches per plant, plant dry matter, number of siliquae per plant, number of seeds per siliqua and seed yield. Split application of nitrogen (recommended basal dose + foliar spray) significantly increased the morpho-physiological, growth characters and yield attributing parameters. Amongst all the treatments, T10 (Recommended dose of NPK + Foliar spray of 2% urea at 20 DAS and 40 DAS) proved to be the best followed by T6 (Recommended dose of NPK + Foliar spray of 1% urea at 20 DAS and 40 DAS) and T9 (Recommended dose of NPK + Foliar spray of 2% urea at 20 DAS). The treatments T10, T6 and T9 recorded 57.36 %, 57.28% and 52.13%, respectively higher seed yield over T1 (Control i.e. without fertilizers) and 26.65%, 26.52% and 17.65% respectively over T2  (soil application of recommended dose of NPK alone).
