Abstract: A field experiment was carried out during kharif seasons of 2017 and 2018 at College farm, Agricultural College, Bapatla, Andhra Pradesh, India to evaluate the response of direct seeded rice varieties to different doses of nitrogen on growth, yield and uptake of nitrogen and were significantly influenced by varieties and nitrogen levels. The experiment was conducted in split plot design with main plot treatments three varieties viz., NLR-145, BPT-5204 and NLR-34449 and sub plot treatments with four nitrogen levels viz., 60 kg N ha-1, 80 kg N ha-1, 100 kg N ha-1 and 120 kg N ha-1 replicated thrice. The results revealed that among varieties, BPT-5204 recorded significantly highest plant height, number of tillers m-2, drymatter accumulation, and yield and nitrogen uptake and was on par with the variety NLR-145 during both the years of study. Among nitrogen levels application of 120 kg N ha-1 showed significantly highest plant height, number of tillers m-2, drymatter accumulation, yield and nitrogen uptake over other nitrogen levels viz., 60 kg N ha-1, 80 kg N ha-1 and 100 kg N ha-1 during two successive years.
