Aman rice. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. Three genotypes significantly influenced almost all the growth and yield parameters in both non-saline and saline field. Genotype Hysun-33 showed maximum germination percentage in non-saline soil but minimum in saline soil. Whereas, KUSL- 1 performed the best in saline soil but worst in non-saline condition. Hysun-33 produced maximum leaf at flowering in both conditions but minimum leaf by BARI Sunflower-2 in saline soil and by KU-SL-1 in non-saline soil. In both non-saline and saline soils, plant height at flowering, head diameter, total seed head</span><span style="font-size: 6.0pt;">-1 </span><span style="font-size: 9.0pt;">and filled seed head</span><span style="font-size: 6.0pt;">-1 </span><span style="font-size: 9.0pt;">were maximum for the genotype Hysun-33 and that of minimum for the genotype BARI Sunflower-2. Genotype KU-SL-1 showed maximum value for 1000- seed weight followed by Hysun-33 in both saline and non-saline soils. In case of seed yield head</span><sup><span style="font-size: 6.0pt;">-1</span></sup><span style="font-size: 9.0pt;">, Hysun-33 performed best in saline soils but worst in non-saline soil. In non-saline soil, KU-SL-1 produced maximum seed yield head</span><sup><span style="font-size: 6.0pt;">-1</span></sup><span style="font-size: 9.0pt;">. Biomass at harvest, head diameter and number of filled seed head</span><span style="font-size: 6.0pt;">-1 </span><span style="font-size: 9.0pt;">was well correlated with number of seed head and seed yield head</span><sup><span style="font-size: 6.0pt;">-1</span></sup><span style="font-size: 9.0pt;">. Thus genotype Hysun-33 may be considered as best for saline and KU-SL-1 for non-saline soil.</span></p> <p style="margin: 0in; margin-bottom: .0001pt;"><em>Bangladesh Agron.

A pot experiment was conducted at polythene house at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur-1706 during May to August, 2017 to determine the effect of salt stress on growth and yield performance of foxtail millets. Five foxtail millets genotypes viz. (i) BARI Kaon-1 (check), (ii) BD-878, (iii) BD-897, (iv) BD-891 and (v) BD-881 were tested under three salt stresses viz. (i) control (0 dS/m), (ii) 6 dS/m and (iii) 12 dS/m. Completely randomized design (CRD) with three replications was followed in the study. The growth parameter viz. stem dry matter, leaf dry matter and root dry matter production of foxtail millets genotypes were significantly varied due to salinity stresses. Salinity stresses also significantly influenced yield and yield contributing characteristics of foxtail millets. The genotypes BD-897 and BD-881 produced the higher dry matter, grains per panicle and grain yield per plants under the saline level of 6 dS/m. The higher stress tolerance index of both the genotypes demonstrate that the genotypes BD-897 and BD-881 were more salt tolerant.</span></p> <p style="margin: 0in; margin-bottom: .0001pt;"><em>Bangladesh Agron.

The Lentil - Mungbean-T.Aus -T. Aman rice cropping pattern was considered as improved pattern (IP) and compared with the farmers’ practice (FP) of Boro - Fallow -T.Aman rice cropping pattern. The Lentil-Mungbean- T.Aus -T.Aman cropping pattern was involved with higher cultivation cost but having the higher rice equivalent yield (REY 15.01 t ha</span><sup><span style="font-size: 6.0pt;">-1</span></sup><span style="font-size: 9.0pt;">), gross return (Tk. 265500 ha</span><span style="font-size: 6.0pt;">-1</span><span style="font-size: 9.0pt;">), gross margin (Tk. 134750 ha</span><sup><span style="font-size: 6.0pt;">-1</span></sup><span style="font-size: 9.0pt;">) and marginal benefit-cost ratio (1.38). This cropping pattern gave 46% higher REY compared to the existing Boro-Fallow-T. Aman rice pattern. The four crop pattern took 345 days in a year for its cycle completion. Incorporation of legume residues into the soil in IP increased soil organic matter, total N, available P and Zn contents, as observed after two crop cycles. The IP increased N, P and K uptake by the crops in the sequence. The apparent balance, i.e. difference between inputs and outputs for N and K was negative. The apparent P balance was positive in IP while it was negative in FP. Therefore, it is concluded that the practicing Lentil- Mungbean-T.Aus-T.Aman rice cropping pattern is a productive and profitable system of production technology in the high Barind Tract.</span></p> <p style="margin: 0in; margin-bottom: .0001pt;"><em>Bangladesh Agron.

The study was conducted in a factorial Randomized Complete Block Design with three replications. The result showed that planting methods had significant effects on the yield of rice. The SRI method along with BRRI recommended fertilizer dose produced the maximum grain yield of 4.49 t ha</span><sup><span style="font-size: 5.0pt;">-1</span></sup> <span style="font-size: 8.0pt;">which was statistically similar with that produced in SRI method day- and soil test-based nutrient management combination. The highest gross margin (Tk. 36,308.00 ha</span><sup><span style="font-size: 5.0pt;">-1</span></sup><span style="font-size: 8.0pt;">) and cost benefit ratio (2.06) were observed in direct seeding of sprouted seed in line sowing method along with BRRI recommended fertilizer dose. So, direct seeding of sprouted seed in line could be a suitable planting method due to reduction of 26.0% production cost associated with seedling raising and transplanting operations.</span></p> <p style="margin: 0in; margin-bottom: .0001pt;"><em>Bangladesh Agron.

An experiment was conducted at the Seed Laboratory, Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Jamalpur in 2011 and 2012 to find out the effect of seed moisture content and types of storage container on soybean seed germination and seedling vigour. In 2011, soybean seed having 94% initial germination was stored at 8, 10 and 12% moisture levels but in 2012 seeds having 96% initial germination was stored at 6, 8, 10 and 12% initial moisture levels in four different types of storage containers viz., polythene bag, plastic pot, tin can and glass jar. weredays after storage ().The experiment was arranged in a factorial completely randomized design with three replications. In 2011, high germination of soybean seed (77-85%) was retained at 200 DAS for those stored at 8% initial seed moisture content (SMC) in any of the containers. Germination index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. Tin preserved higher seed moisture contents of 9.93, 11.71 and 14.15% for seed stored at 8%, 10% and 12% initial seed moisture content, respectively. In 2012, 80-94% seed germination was retained at 200 DAS for those stored at 6% initial SMC in any of the containers. The germination declined to a range between 75.0 and 91.3% within 200 DAS at 8% initial SMC while those stored at 12% SMC showed rapid germination loss and the value showed down to between 9.3 and 22.0%. Vigour index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. Tin also Seeds stored in tin container showed the higher final seed moisture contents irrespective of initial seed moisture content.</span></p> <p style="margin: 0in; margin-bottom: .0001pt;"><em>Bangladesh Agron.
