RESPONSE OF RICE GENOTYPES IN ROOT RELATED TRAITS UNDER WATER DEFICIT CONDITIONS Jasmine, H. S.; Ahamed, K. U. The experiment was conducted for varietals screening of root related traits in ten rice genotypes collected from ERR! (BR21. BR24, BRRI dhan42. BRRI dhan43. BRR! dhiUl48. BRR! dhan55. BR6976-! I-I. OM I49(), BR6976-2B-15) with two water stress-tolerant genotypes Hashikalmi and Dharial used as check. The experiment was carried out at the field of Agricultural Botany in the rain protected polyethene shed house to avoid rain under natural conditions in root elongation perforated polyethene lubes which was 70 em in length. At the beginning, the rice seedlings were normally irrigated up to fourteen days for ensuring normal growth. From fifteen days onwards water stress was imposed till thirty days and data were recorded using .H)-days old seedlings. The maximum length of the root was found in BRR! dhan55 (22 em). Haxhikalmi C~2 em). Genotypes BR1I. BR24. BRR! dhan43. BR 6976-11-1 produced shortest roots than the water stress-tolerant genotypes. BRRI dhan55. Hashikalrni and Dharial. Under water stress conditions. the root shoot ratio was higher in tolerant genotypes and was lower in genotypes BR21. BR24. BRRI dhun-l J, BR 6976-11-1. The decreased root shoot ratio indicated that root dry matter rather than shoot dry matter was more affected due to water deficit conditions. Our findings suggest that deep root, small shoot and higher root-shoot ratio are the characteristics, of water stress-tolerant genotypes. J. Sher-e-Bangla Agric. Univ.. 9(2): 29-35, July 2018

COMPARATIVE ANALYSIS OF PHYSIO-MORPHOLOGICAL TRAITS OF CHILLI GROWN UNDER DISTINCTIVE ENVIRONMENTAL CONDITIONS IN BANGLADESH Khan, M. A. I.; Shapla, T.; Farooque, A. M. In Bangladesh. chilli is one of the popular spices grown in many different places around the country and in the world. This spice grows in many different environments: however, the yields do vary. In the present investigation. the open field and glasshouse experiments were compared using cultivars C0277 and C0272. The results revealed that C0277 produced the highest leaf area per plant and the lowest in rout volume. fruit diameter and stem dry weight for both field and glasshouse. For the cultivur C0272. the highest was fruit length and individual fruit weight for the field condition and the lowest in fruit diameter and stern dry weight in the glasshouse. Therefore. it can be concluded that chilli cultivar, C0277 can be grown in a glasshouse with a higher yield as compared to the open field condition. J. Sher-e-Bangla Agric. Univ .. V 9 (2): 23-28.

DETERMINA TION OF THE FEASIBLE INTERVENTIONS TO EV ALUA TE THE DEVELOPMENT AND STRATEGY FOR REDUCING DISASTER RISK IN THE COASTAL AREA OF BANGLADESH Amena, N.; Shapla, T.; Haque, A. A research work was conducted on quantifying risk reduction interventions to assess the progress and strategies for disaster risk reduction in the coastal areas of Bagerhat, Bangladesh. TIle study covered four unions, viz, Sharonkhola. which was the worst affected by the cyclone associated with storm surge. Primary and secondary data sources were used in this perspective. Death and damage of properties due to SIOR 2007 had been found to be enormous. Different NGOs and donors gave relief in cash and kinds. Natural and man-made disasters have existing working plans such as wide and raised embankment, saline tolerant trees. improved infrastructure. technology-based warning system. emergency shelter etc. which may be adapted for reduction of disaster risk in the Bagerhat coast in particular. Moreover. the homestead can be protected from cyclone and storm surge by raising fruit and timber trees. A small family can meet up its all basic requirements and expenditure if the area of the homestead is 0.33 acre at the minimum. Such homestead agroforestry system would be able to minimize disaster risk. J. Sher-e-Bangla Agric. Univ .. 9(2): 15-22, July 2018

VARIETAL PERFORMANCE OF TRANSPLANT AMAN RICE AS INFLUENCED BY NUMBER OF SEEDLINGS HILL-] UNDER SUBMERGENCE CONDITION Khanam, M. S.; Hossain, A. S. M. I.; Jahan, N.; Islam, M. K. The research work was carried out at the Agronomy Field Laboratory of Patuakhali Science and Technology University, Patuakhali during the Aman season (July to December, 2016) for optimizing number of seedlings hil l ' of rice varieties grown under submerged condition. The experiment was laid out in a randomized complete block design with three replications. Three levels of seedling numbers viz. 2 seedlings hin-',4 seedlings hillland 6 seedlings hill-' with three varieties viz, BRRI dhan41 ,BRRI dhan53 and BRRI dhan54 were considered in the study. The number of seedlings hilr' did not significantly influence all the parameters. The highest grain yield (5.54 t ha"), straw yield (5.30 t ha-I), total tillers hil l' , (9.06), effective tillers (8.98) and 1000 grain weight (23.29g)were obtained at 4 seedlings hilr'. The lowest grain yield (5.43 t ha'), 1000 grain weight (23.15g), total tillers (8.36), effective tillers (8.33) and plant height (132.11 em) were obtained from 2 seedlings hil"'. Variety showed significant differences for plant height, total tillers hin-', effective tillers hill", grains panicle", sterile spikelets panicle" and 1000- grain weight. BRRI dhan54 showed with the highest grain yield (5.75 t ha'), straw yield (5.301 ha'), grains panicle' (150m, plant height (151.33cm) and higher harvest index (52.00%). BRRJ dhan41 produced lower grain yield (5.32 t ha-I), grains panicle" (131.5), total tillers (7.50), effective tillers (7.58) and sterile spikelets panicle' ' (40.3 I ). The interaction of variety and number of seedlings hilr'had significant effect on plant height, total tillers hilr', number of grain panicle", number of sterile spikelets panicle" and 1000 grain weight. BRRJ dhan54 with 4 seedlings hill" gave highest yield (6.06t ha'). straw yield (5.45t ha-'),1000 grain weight (23.34g), total tillers (10.50) and effective tillers (10.33). J. Sher-e-Bangia Agric.
