This study was carried out to evaluate the economic benefits of sweet gourd relay with transplanted aman rice under farmer’s field condition at Farming System Research and Development (FSRD) site, Jalalpur and Multi Location Testing (MLT) site, Zakigonj of Sylhet region during 2012-2013 and 2013-2014. The treatment combinations T1: T. aman rice / sweet gourd (var. Mollika), T2: T. aman rice / sweet gourd (var. Hatirpara) local, T3: Sweet gourd (var. Mollika) sole, T4: Sweet gourd (var. Hatirpara) sole and T5: T. aman rice sole (var. Binadhan-7) was maintained. The study was based in a randomized complete block (RCB) design with six dispersed replications. Results in terms of the crops yield, rice equivalent yield, gross return and net return with benefit cost ratio showed higher in sweet gourd / transplanted aman rice relay cropping system. So, sweet gourd  relayed with  transplanted aman rice could be an economically viable technology, instead of sole cropping, for  best utilization of fallow land with residual soil moisture in Sylhet region.Bangladesh Agron.

The experiment was conducted at Multi Location Testing (MLT) site, Moulvibazar, Bangladesh during rabi season of 2016-17 and 2017-18 to study the profitability of intercropping of hybrid maize with vegetables and spices. Five intercrop combinations of hybrid maize along with sole maize were arranged in randomized complete block design (RCBD) replicated six times. There were six treatments viz., T1: Maize + potato, T2: Maize + red amaranth, T3: Maize + spinach, T4: Maize+ data shak, T5: Maize + coriander and T6: Maize as sole. The grain yield of maize in intercropped combination varied significantly. The highest grain yield (9.71 t ha-1) was in sole maize. The highest maize equivalent yield 15.60 t ha-1 was recorded from the treatment T1 (100% maize + potato) whereas the lowest yield (8.61 t ha-1) was obtained from the treatment T6 (sole maize). The highest gross return (Tk. 312000 ha-1) and benefit cost ratio (3.29) was obtained from the treatment T1 (100% maize + potato). On the contrary, the lowest gross margin (Tk. 101600 ha-1) was obtained from treatment T2 (maize + red amaranth). It revealed that the combination of maize with potato was more compatible and profitable intercropping system in Sylhet region of Bangladesh Bangladesh Agron. J. 2018, 21(2): 73-78

Benefits And Costs

Port dredging to accommodate larger vessels can create substantial national economic benefits. However, how affected individual states fare economically with dredging is often unclear and can be an important issue. The benefits and the costs to Delaware residents of dredging—with the recent proposed deepening of the Delaware Bay and River main federal channel as a case study—are examined. Benefits include ( a) lower transportation costs that residents might receive on imported goods, ( b) profits that residents would realize if cost savings (e.g., on refinery products) were not passed forward to Delaware users, ( c) project costs that residents would bear as federal taxpayers, and ( d) benefits that residents would realize if the use of dredged sediments for planned beach renourishment created savings to the state. Sensitivity analyses are used to reflect uncertainty in outcomes. The estimated net present value to Delaware today of all future annual quantifiable benefits and costs ranges between $15,528,393 and $14,195,700 over 50 years at 5.875%. Stated another way, the quantified net benefits for Delaware imply a benefit-cost ratio between 2.07 and 1.89. Hence, for every dollar of the $7.5 million that Delaware would pay as a nonfederal cosponsor, estimated quantifiable net benefits to the state are $2.07 to $1.89. Some benefit and cost estimates are vehemently debated between interested parties, and not all benefits and costs can be quantified.

Mixed crop cultivation of lentil and rapeseed could be a promising technology for yield maximization. The field experiment was carried out at multilocation testing site, Kashinathpur, Pabna during the rabi season of 2011-12 and 2012-13 to verify the performance of rapeseed as mixed crop with lentil at different seeding ratios. The treatment comprises for the experiment were T1: Sole lentil (100%), T2: Sole rapeseed (100%), T3: Lentil (100%) + Rapeseed (10%), T4: Lentil (100%) + Rapeseed (20%), T5: Lentil (100%) + Rapeseed (30%) and T6 :Farmers’ practice :Lentil (100%) + Rapeseed (15%). The highest lentil equivalent yield (2.22 t ha-1 in and 2.48 ) and maximum land equivalent ratios (1.27 and 1.28) were observed in T4 treatment in 2011-12 and 2012-13, respectively.. It was noted that all the mixed cropping systems produced higher equivalent yield and LER than that of their corresponding sole crops. . Cost and return analysis showed that the highest net return (Tk. 127774 ha-1) was found in T4 treatment while sole rapeseed gave the lowest net return (Tk. 60540 ha-1). Net return was always higher under mixed cropping system than that of sole cropping. The highest benefit cost ratio 3.48 was recorded from Lentil (100%) + Rapeseed (20%) where as the minimum (1.39) from soli rapeseed.Bangladesh Agron. J. 2014, 17(1): 33-40

The terrace ecosystem is considered as hotspot of jackfruit tree (Artocarpus heterophyllus Lam) in Bangladesh having potential for understory cropping. However, most of the jackfruit orchards are often found utilized or underutilized. A field experiment was conducted under the jackfruit orchard to study the performance of aroids (Colocasia esculenta L.) from April to October, 2017 in Belabo upazila of Narsingdi district. Four distances (1, 2, 3 and 4 m) from the base of jackfruit tree were considered for aroid planting to evaluate its performance as agroforestry crop in comparison to sole aroid. Land use and economic performances of agroforestry and sole systems were also evaluated. The results indicated that the production of jackfruit increased by 62.73%, while the yield of aroid reduced by 33.48% in agroforestry systems as compared to the yields of sole (non-agroforestry) systems. In agroforestry system, the photosynthetically active radiation (PAR) was severely reduced by 85-77% on aroid crop that caused yield reduction. It was also observed that soil temperature was lower in agroforestry system as compared to sole cropping of aroid, while soil moisture showed inverse trend in sole jackfruit. Economic analysis in terms of benefit cost ratio (BCR) was 2.60 in agroforestry, while the BCR of sole aroid was only 1.83. The land equivalent ratio (LER) was 2.31 in agroforestry system. The present results indicate that aroid cultivation in jackfruit-based agroforestry system under terrace ecosystem can ensure overall higher production and improve economic return. Ann.

A field trial on soil test based (STB) fertilizer doses was conducted during the year of 2017-2018 and 2018-2019 in Jashore region (AEZ-11) to find out the most suitable fertilizer doses for four crop based cropping pattern considering the agronomic feasibility and economic return of the system. The experiment consisted of eight different treatments viz. T1: 100% NPKSZnB (STB), T2: T1 + 25% N, T3: T1 + 25% NP, T4: T1 + 25% NK, T5:T1 + 25% PK, T6:T1 + 25% NPK, T7: 75% of T1, T8: Native fertility. Randomized complete block design (RCBD) with three replications was followed. Data revealed that seed yield of mustard was remarkably influenced by fertilizer treatments while grain yield of other components of the cropping system was not affected significantly by the treatments except control or native fertility. It was observed that 25% more NPK over 100% STB dose provided the highest yield of all the component crops. The highest rice equivalent yield (3.34 t ha-1) was recorded from T6 and the lowest (1.88 t ha-1) from T8 treatment. Maximum gross return (Tk. 420000/ha) and marginal benefit cost ratio (4.08) were also obtained from T6 treatment. So, 25% NPK+ 100% STB dose of fertilizer could be followed for productive and remunerative rice based cropping system Mustard-Boro-T. Aus-T.Aman in AEZ-11. Bangladesh Agron. J. 2021, 24(1): 109-117

AbstractAn areawide program for biological control of the alfalfa weevil showed expected economic benefits of $2.2 billion, expressed in present value terms. Alfalfa producers and consumers of livestock products are the main beneficiaries. The control program was highly successful, with a benefit/cost ratio of about 91. Not all areawide biological pest control programs will be as successful; a benefit-cost analysis like the one described here should be performed before areawide control is initiated to identify programs expected to provide economic benefits.

A new approach explores the economic viability of dedicated bus reserves purely for bus bridging purposes. The approach estimates feet costs and user benefits of reduced delay by improving the response to unplanned rail disruption. The feasibility of dedicated bus reserves has not been considered in previous research. Sourcing buses for bus bridging purposes is problematic during weekday peak periods, which coincide with the highest demand for rail travel. At all other times spare buses are available. Consequently, a dedicated bus reserve would exist mainly to provide bus bridging in the peak. Results suggest that a dedicated bus bridging reserve can be economically viable. Of 18 corridors studied, a dedicated reserve was feasible for 78%. Economically viable corridors have a benefit–cost ratio ranging between 1.5 and 9.7 (average, 4.5). Reserves were not feasible where existing rail demand, disruption likelihood, or both were low. Sensitivity tests explored viability with more conservative assumptions. In each test, the dedicated bus reserve in most corridors remained economically viable. The research suggests that a dedicated bus reserve should be considered by rail operators worldwide because of strong net economic benefits. However, reserves are a net cost (with no income), so investment must be based on economic, not financial, benefits. This aspect suggests that government authorities, rather than commercial operators, may find a dedicated reserve more feasible. This approach illustrates where reserves might best be allocated to maximize investment returns.

A field experiment was conducted to explore the feasibility of blackgram fodder production in Aus rice as intercropping system at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from March to July 2009. The experiment was laid out in a randomized complete block design with three replications. The fodder crop was sown at various densities as sole crop for comparison. Growth parameters, yield components and yields were higher in sole cropping. Economic analysis reveals that intercropping systems showed better performance in terms of gross, net return and benefit cost ratio compared to sole cropping of main or fodder crop at various plant populations per unit area. Intercropping blackgram as fodder with 50 kg seed ha-1 in Aus rice row sowing of 25 cm would be the promising fodder production with minimum grain yield loss of rice with higher profit.

A field experiment was conducted at the farming system research and development site Lebukhali, Patuakhali of Bangladesh Agricultural Research Institute during 1999 and 2000 to study the effect of seed soaking duration before sowing on yield of two mungbean varieties BARImung-2 and BARImung-5. Seeds were soaked with fresh water for 0, 2, 4, 6 and 8 hours. The results revealed that plants produced with 4 hours soaking gave the maximum seed yield (1379 kg/ha). BARImung-5 produced higher yield (1457 kg/ha) than that of BARImung 2. Control (no soaking) gave lower yield. The highest benefit cost ratio (3.51) was obtained from 4 hours soaking. Key words: Mungbean variety, time of seed soaking, yield.
