Abstract
Salt-tolerant Boro rice response under the interaction of variety and urea fertilizer was assessed in the southern coastal region of Bangladesh for developing coastal agriculture in Bangladesh. A field experiment was carried out at the research field of Agriculture department, Noakhali Science and Technology University (NSTU), Noakhali-3814 in a Randomized Complete Block Design (RCBD) with two varieties viz. BINA dhan-8, BRRI dhan-67 and three doses of urea viz. 250 kg/ ha., 150 kg/ ha. and 120 kg/ ha. were used as treatments where each treatment was replicated three times. Data were collected on plant height (cm), tiller/hill, grain/panicle, 1000 grain weight (g), grain yield (t/ha.), straw yield (t/ha.) and harvest index (%). All the parameters were influenced significantly by the interaction of variety and different doses of urea fertilizer and better performance was obtained from the variety BINA dhan-8 and the doses of 250 kg urea/ ha. Finally, the present study suggests that for obtaining higher yield salt-tolerant BINA dhan-8 variety may be cultivated with 250 kg urea/ ha. in the southern coastal region of Bangladesh.

Highlights
The highest plant height (95.36 cm) was observed in Bangladesh Institute of Nuclear Agriculture (BINA) dhan-8 compared with Bangladesh Rice Research Institute (BRRI) dhan-67 (85.57 cm) and this result is consistent with some other researcher (Sarker et al, 2013; Shel et al, 2015; Islam et al, 2015; Alam et al, 2012)
BRRI dhan-67 produced more tiller/hill (18.12) than BINA dhan-8 (13.22) which is similar with the findings of other researcher (Islam et al, 2015; Tyeb et al, 2013; Sarker et al, 2013)
Highest number of grain/ panicle was found in BINA dhan-8 (131.08) in comparison with BRRI dhan-67 (107.9)
Summary
About 76% of the total population of the country live in rural areas and 47.5% of the total manpower is involved in agriculture (BBS, 2016). In Bangladesh, rice is the most extensively cultivated cereal crop. It provides about 75% of the calories and 55% of the protein in the average daily diet of the people of our country (Bhuiyan et al, 2002). It supplies nearly 48% of rural employment, about 2/3rd of total calorie intake and about 50% of the total protein intake of an average person in the country (BBS, 2013).
