The effect of integrated nutrient management (INM) on crop yield in the potato-rice-rice pattern was studied through some field experiments in Bangladesh during 2009-2010. There were six fertilizer-manure treatments - control (no fertilizer or manure), farmer's practice, 100% recommended rate of nutrients from fertilizers, and the rest treatments with 100% nutrients from manure (5 t ha-1 for cow dung, 3 t ha-1 for poultry manure or 10 t ha-1 for compost) supplemented with fertilizers. Their direct effects were evaluated on potato ('Granola', Netherlands origin) and the residual effects on Boro rice ('BRRI dhan28') and T. Aman rice ('BINA dhan7'). The experiment was laid out in a randomized complete block design, with three replications. These trials were conducted in farmers' plots across two upazilas (sub-districts) of the country. Integrated use of manure and fertilizer produced significantly higher tuber yield at all 16 sites over sole fertilizer treatment. Effect of INM with compost or poultry manure was found better at all sites than that with cow dung. Integrated use of poultry manure or compost with fertilizers demonstrated about 25% yield increase over 100% fertilizer treatment. Positive residual effect of manure was observed in the following two rice crops. A separate field trial was made to evaluate the effect of INM with cow dung or poultry bio-slurry on potato crop. It revealed that bio-slurry had better effect on tuber yield compared to cow dung or poultry manure. This study indicates that integrated use of manure and fertilizers is a better practice for obtaining higher crop yield.

A field experiment was carried out to investigate the effects of prilled urea (PU) and urea super granule (USG) alone and their combinations with poultry manure (PM) on growth and yield of transplant Aus rice (cv. BR 21) and field water quality. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The treatments were T1: Control (no fertilizer), T2: (165 kg N ha-1 from prilled urea), T3: (119 kg N ha-1 from USG), T4: (82 kg N ha-1 from prilled urea + 3 t ha-1 poultry manure) and T5: (56 kg N ha-1 from USG + 3 t ha-1 poultry manure). The highest grain (3.19 tha-1) and straw yields (4.51tha-1) were obtained from treatment T5 (56 kg N ha-1 USG + 3.0 t ha-1 poultry manure) while the lowest grain (1.99 tha-1) and straw yield (3.38 tha-1) were recorded for T1 (control). Treatment T3 (119 kg N ha-1 from USG) performed better than T2 and T4 indicating the superior effect of USG over prilled urea. The N, P, K and S contents in the grain and straw and their total uptake were influenced profoundly due to application of PU, USG alone or in combination with poultry manure. In case of rice field water quality, the USG generated available NH4-N slowly but spontaneously over the entire growth period compared to prilled urea indicating a beneficial role of USG. The other properties of field water like pH, EC were also influenced by the application of prilled urea, USG and poultry manure. The overall results indicate that application of USG in combination with poultry manure was more effective in producing higher rice yield and at the same time reduce water pollution.

An experiment was carried out during rabi season of 2011-2012 in the experimental field of Soil Science, Bangladesh Agricultural University (BAU), Mymensingh. The objectives of present research work was to evaluate ash as an alternative source of potassic fertilizer for potato cultivation. The treatment combinations were i) Control (No K), ii) 100% K of recommended dose from muriate of potash (MoP), iii) 75% K from MoP+ 25% K from ash, iv) 50% K from MoP + 50% K from ash, v) 25% K from MoP + 75% K from ash, and vi) 100% K from ash. The result of the experiment indicated that various combinations of ash and MoP influenced the yield, yield contributing characters (length of the tubers, breadth of the tubers, number of tubers per hill, weight of tubers per hill, weight of ten tubers and gross yield of tubers per plot), K content of po tato as well as weed infestation. Among the treatments the highest yield was obtained from 50% K from MoP + 50% from ash (T3) treated plot. The K content in the potato tuber and weed infestation was also highest for that plot. Considering the yield contributing parameters, yield and number of weeds the T3 (50% K from MoP + 50% K from ash) treatment was found more suitable than others.

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.
