U.; Naher, N.; Halim, A.; Habib, Z. F. B. An experiment was conducted during June 10 December. 2013 10 observe the effect of submergence at seedling stage on some of the morphological attributes and yield of some T. aman rice (Orv~a saliva L.) varieties. Four submergence duration. viz .. control (no submergence). six days submergence. ten days submergence and fourteen days submergence and six varieties, viz., BRRI dhanSI, BRR! dhan46, BRR! dhan34. BRR! hybrid dhanl, BRRI hybrid dhan2, ACI hybridl were used for this experiment. The experiment was laid OUI in split plot design with three replications. All parameters were significantly affected by the submergence duration and variety. The highest (8.S0 t ha") grain yield was found from the combination of no submergence with BRRI hybrid dhanl and the lowest (1.20 t ha') from the combination of fourteen days submergence with BRRI dhan34. BRR! dhanSI followed by BRRI hybrid dhan I showed higher submergence tolerance and thus proved as tolerant varieties. On the other hand, BRRI dh,m34 and ACI hybrid I were susceptible to submergence.

K.; Ahamed, K. U.; Alam, A. K. M. M.; Masum, R. M. Bangladesh is highly vulnerable to sea level rise. Both water and soil salinity along the coast is increasing with the rise in sea level, destroying normal characteristics of coastal soil and water. A soil survey was conducted in Satkhira district on March to July 2009 and soils samples were collected from 30 sites at 0.5 km distance and 0-50 ern, 50-100 cm and 100-150 ern depth and analyzed to determine the effect of salinity on soil properties. A field experiment was conducted from December 2009 10 March 2010 in Satkhira district to observe the yield performance of eight different tomato varieties for growing under saline area by RCBD with three replications. In the saline soils of Satkhira pH value of the surface horizon was slightly lower (5.37) than those of the subsoil (7.70). Cation exchange capacity (CEC) and organic mailer was medium to high status. nutrient deficiencies of total nitrogen, phosphorous and potassium were quite dominant but sulphur was high (15.0 to 20 mg/IOO kg). Exchangeable sodium. potassium. calcium and magnesi urn were in high level. The dominant water soluble cations were Na '. Ca", Mg'+ and K' and anions CI· and sol. In the field experiment, each tomato varieties showed a special criterion among others. variety BARI Tomato? gave the highest yield (100.33 t/ha) whereas BAR I Tomato I4 showed the highest size (17.0 cm) among others. The highest number of fruits/plant was recorded from BARI Tomato I I (212.33) which was cherry type and the lowest number was recorded from BARI Tomato 4(23.66). So. soil salinity is the most dominant limiting factor in saline regions. especially during the dry season and cropping intensity wi II be increased by adopting proper soil and water management practices with the introduction of salt-tolerant tomato varieties in saline areas.

G.; Latif, M. A. Dengue is a viral disease caused by dengue virus transmitted by Aedes mosquitoes. Extensive use of chemical insecticides for control of diseases vectors has created problems related to pesticide resistance to vectors. adverse environmental effects. high operational cost. pest resurgence and vertebrate toxicity. Hence the emphasis should be given on botanical insecticides which are more eco-friendly and effective. This study was conducted to evaluate the potential of some indigenous plant extracts to control the larva of mosquito in the laboratory of Sher-e-Bangia Agricultural University, Dhaka. The bioassay of the extracts revealed their high potential as larvacides which increase with the increase in concentration of 2. 5 and 10 mgIL respectively. The Nepeta cataria showed highest mortality rate at different concentration of the extract with LC,,, of 0.98 mg/L. The phytochemical analysis shows the three extract to contain secondary plant metabolites like alkaloids. flavonoids, saponins and terpenoids at different concentrations. The study revealed that the extracts are very potent against the larva of the mosquito, therefore more effort should be made to harness the potential of these available raw material as botanical pesticide.

N.; Bari, A.S.M. Fazle The experiment was conducted to study effect of different levels of SA (SA) on yield and yield attributes of Triticum aestivum (BARI Gom 27). The experiment included four levels of SA viz. 0 ~M. 200 ~M. 500 ~M and 1000 ~M SA. The experiment was laid out in a randomized complete block design having 7 treatments with three replications. The treatment combinations were as follows: T, = No recommended irrigation + 0 flM SA. T~ = recommended irrigation + 0 flM SA. T, = No recommended irrigation + 200 u M SA. TJ = recommended irrigation + 200 uM SA. T5= No recommended irrigation + 500 flM SA, T.= recommended irrigation + 500 flM SA and T7 = recommended irrigation + 1000 u M SA. The results revealed that yield and yield contributing characters were significantly influenced by the foliar application of SA. The maximum plant height (85.17 ern) was obtained from the T, treatment and spike length (14.80 em) was obtained from the T7 treatment. The maximum number of effective tillers per m' (297.67), maximum number of grains/spike (42.03), maximum filled grains/spike (39.9), highest 1000 grain weight (56 g), highest grain yield (4.23 t/ha) and straw yield (5.20 r/ha) were found in the treatment T7. The lowest unfilled grains/spike (2.13) was obtained from the T, treatment. On the other hand. in all cases minimum results were observed in the control treatment (T,). The results showed that grain yield of wheat increased with increasing level of SA up to 1000 u M with recommended irrigations. The yield increasing trend was also observed in the treatments having SA with no recommended irrigations (T,. T" T,). These results might be due to the foliar application of SA because SA improves the water use efficiency through the reduction of stomatal aperture. The aphid infestation of wheat was completely removed by the foliar application of higher doses of SA (1000 fl M). Our results indicated that drought stress regulatory mechanisms could be improved in wheat through the foliar spray of SA. Taken together, it can be concluded that the recommended irrigations with foliar application of SA could be applied to increase wheat yield. J. Sher-e-Bangla Agric. Univ., 9(1): 09-17.
