This study was carried out to determine the effect of salinity on growth, antioxidant contents and proximate compositions of Sabah snake grass (Clinacanthus nutans (Burm. f.) Lindau). Six salinity levels were used, namely 0 (control), 4, 8, 12, 16 and 20 dS/m. Highest salinity level, 20 dS/m, significantly increased the phenolic content (1.95 mg GAE/g), flavonoids content (3.84 mg QE/g), and proximate compositions such as ash content (19.83%), crude protein content (16.43%), crude fat content (18.45%) and crude fiber content (10.73%) of C. nutans although the plant growth and leaf relative water content were reduced. Therefore, salt-stressed C. nutans can be considered as excellent sources of antioxidant contents and protein for human consumption.

Residual effects of urea with poultry manure (PM) and biogas slurry (BS) on okra after Boro rice have been studied. Yield attributes and yield of rice and okra were the best in the treatment receiving 50% of recommended dose equivalent to 94 kg/ha N from urea and 50% N from PM equivalent to 4.5 t/ha. The same treatment combination recorded the highest grain yield of rice of 6.9 mt/ha. Application of 50% urea N and 50% PM N in preceding rice crop highest grain yield of rice (6.83 mt/ha) and fruit yield of okra (14.16 mt/ha) was obtained. The contents of organic matter, total N, available P, exchangeable K, available S, exchangeable Ca, exchangeable Mg and available Zn and pH in post-harvest soils increased compared to initial soil indicating the improved soil fertility. Results indicated that N at the rate of 94 kg/ha along with 4.50 mt/ha PMwas the best combination for producing rice and okra in rice-okra cropping sequence.

Fertilizer dose for Okra- Fallow-T. Aman cropping sequence was determined experimentally in the saline soils of the coastal regions of Bangladesh. Application of 25% more N, P and K fertilizers with 100% STB (N68.5P32.2K8.9Zn2kg/ha for Okra and N68.5P15K9.7Zn1.5kg/ha for T. Aman) increased fruit/plant, fruit length (cm) and individual fruit weight of okra, and effective tillers/hill, panicle length, filled/panicle and 1000- grain weight of BRRI dhan30. As a result the highest fruit of okra (12.89 t/ha) and grain yield of BRRI dhan30 (5.06 t/ha) were obtained from this treatment. Therefore, 25% increase of N, P and K fertilizers of STB fertilizer doses might be recommended for okra - Fallow-T. Aman cropping sequence in saline areas of coastal belt.

In the present research, the growth responses and quality of turfgrass species were studied under salinity stress. Chlorophyll content, relative water content, proline accumulation, and mineral content analysis used in this study were highly related with one another, indicating their mutual effectiveness in predicting relative salinity tolerance. Relative water and chlorophyll content were found high in Paspalum vaginatum Sw., Zoysia matrella L., and Cynodon dactylon (L.) Pers. 'satiri', whereas, proline content was low. These three species were less affected by selectivity of saline ion (Na) uptake. Physiological parameters, indicating that P. vaginatum, Z. matrella and C. dactylon 'satiri' are more salt tolerant than C. dactylon 'tifdwarf'. The SEM micrograph showed salt gland excretion presence on Z. matrella, C. dactylon 'satiri' and C. dactylon 'tifdwarf' leaves. Roots cortex cell collapsed on C. dactylon 'tifdwarf' was greater compared to other three species.

To select the most suitable salt tolerant turfgrass species, an experiment with five salt water concentrations viz., 0, 12, 24, 36 and 48 dS/m was carried out. The result of this experiment revealed that relative shoot growth of Paspalum vaginatum Sw., Zoysia matrella (L.) Merr. and Cynodon dactylon (L.) Pers. 'satiri' were 80, 68 and 67%, respectively over the control at the highest salinity level (48 dS/m). Paspalum vaginatum produced the highest shoot density in every salinity levels among the tested species. Turf quality ratings followed the same trend as leaf firing and turf colour index, which were the best in P. vaginatum and Z. matrella across all salinity levels, but quality ratings were slightly better in P. vaginatum due to higher shoot densities at all salinity levels compared to Z. matrella and C. dactylon 'satiri'. Therefore, P. vaginatum was found to be the most suitable salt tolerant species compared to Z. matrella and C. dactylon 'satiri'.

Several approaches to improve grain nutritive values involve in increasing seed accumulation of protein and micronutrients in rice. Therefore, a study was conducted to select a suitable combination of dicyandiamide (DCD) with organic manure (OM) and urea to improve protein and mineral content in rice grain of MR219. The protein (9.07-12.50%) and Ca, Mg, Zn, Cu, Fe and Mn concentrations increased from 1.92 to 21.05, 3.56 to 18.25, 2.25 to 20.22, 9.14 to 25.66, 3.34 to 27.20 and 5.17 to 23.86%, respectively due to the application of DCD with urea and OM. Moreover, the highest content of protein in grain was obtained for the application of DCD with urea and oil palm compost (OPC). Iron and Mn contents were also highest for DCD with urea and OPC, but Ca, Mg, Zn and Cu contents were highest for DCD with urea and poultry dung (PD) and kept similarity with DCD with urea and OPC.

The accurate prediction of N transformation is an importantrequisite for optimizing N use efficiency in cropping systems. Anincubation study was conducted to verify the impacts of nitrificationinhibitor (NI) with organic manure (OM) and urea on N dynamicsand N2O emission in acid sulphate soil. The conducted experimentwas two-level factorial with 4 N sources (N1 = 100% of N from urea,N2 = 75% of N from urea + 25% N from rice straw, N3 = 75% of N fromurea + 25% of N from cow dung and N4 = 75% of N from urea + 25%of N from poultry dung) and two levels of NI (with and without DCD).The NI (Dicyandiamide — DCD) with OM + urea enhanced mineralN contents and it was the highest (255.07 μg∙g–1) for urea with DCDapplications. The highest net N-mineralization (213.07 μg∙g–1) wasrecorded for the application of urea with DCD and net nitrification(16.26 μg∙g–1) was recorded for the application of urea alone, but thehighest cumulative N2O emission (5.46 μg∙g–1) was in urea + poultrydung (PD). In addition, DCD most effectively inhibited net nitrification(28.78%) and N2O emission (32.40%) from cow dung (CD) and ureain the tested soils. The combination of DCD with CD and urea wasmore effective in reducing N2O emissions (43.69%). These resultssuggest that the DCD with CD and urea may be the most potentialcombination to reduce nitrification and N2O emission as well as Nloss from acid sulphate soil. © 2016, Instituto Agronomico.

This article decribes the nutrient composition of four strawberry genotypes cultivated at the Sher-e-Bangla Agriculture University horticulture farm in Dhaka (Bangladesh). AOAC and standard validated methods were employed to analyse the nutrient composition. Protein, fat and ash contents were found to be vary significantly (LSD < 0.05), while the variation in moisture (LSD < 1.33), dietary fibre (LSD < 0.15) and total sugar (LSD < 0.09) were found to be insignificant among the genotypes. Vitamin C content ranged from 26.46 mg to 37.77 mg per 100 g edible strawberries (LSD < 0.060). Amount of carotenoids were found to be very low being in a range of 0.99-3.30 μg per 100 g edible fruit. Analysis of mineral revealed that strawberry genotypes contained a wide array of minerals including Ca, Mg, Na, K, P, Mn, Zn, Cu and Fe; most of which varied significantly (LSD < 0.05) among the genotypes. Strawberries could be a potential dietary supplement for vitamin C along with minerals, particularly for the children who do not like local fruits, but love to eat the colourful strawberries. © 2015 Elsevier Ltd.

Shifting cultivation is a form of land use among resource poor communities with a rotation of cultivation and fallow in the same unit of land. Millions of indigenous people are dependent on shifting cultivation practice, with majority households for subsistence living. This practice is in transition these days with rising population of shifting cultivators and demand for more food. Bangladesh like other neighboring countries has hills which are subjected to degradation due to deforestation enhanced by shifting cultivation. There has been a continuous debate on shifting cultivation. Soil erosion is in large extent in Chittagong Hill Tracts (CHT) due to faulty cultivation in hill slopes, shifting cultivation, change in land use and reduction of land cover. This paper provides a review on shifting cultivation practice in the world with reference to Bangladesh, with an insight on emerging land use transition, its impacts and future priorities. © 2011 Academic Journals.
