This experiment was conducted in Lavras - state of Minas Gerais (MG), Brazil, in a protected environment, and aims to estimate the irrigation depths that maximize productivity and economic returns in the cultivation of asparagus bean and analyze the economic viability of irrigation management. The experimental delineation was randomized blocks with five treatments and four replications. The treatments consisted of five drip irrigation depths: 40, 70, 100, 130 and 160% of water replacement depth up to field capacity. The depths of water that maximize productivity and economic returns were obtained from the regression model adjusted to productivity data, cost of product relations and water cost. The economic viability was achieved on the benefit/cost ratio basis. The depth with the maximum economic return was estimated in 434.4mm, with a productivity of 35,160.6kg ha-1, which is economically viable for the cultivation of asparagus bean, with a expected profitability of R$ 1.70 for every real invested.

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.

Lentil (Lens culinaris) is one of the oldest pulse crops and most nutritious among the rabi pulses. Front line demonstration was conducted at farmer's field of Gazipur UP, India, involving improved technology. The productivity and economic returns of lentil from improved technologies were calculated and compared with the corresponding farmer's practices (local check). Results revealed that improved scientific lentil production practices recorded higher yield as compared to farmer's practices. The improved technology recorded higher yield of 13.87 q/ha and 14.70 q/ha in the year 2015-16 and 2016-17, respectively over farmer's practice10.90 and 10.67 q/ha. In the economic front too, improved technology gave higher gross return (90155 and 88200 Rs./ha), net return (63336 and 65714 Rs./ha) with higher benefit cost ratio (3.36and 3.92) as compared to farmer's practices. The variation in per cent increase in the yield was attributed by lack of scientific knowledge, and poor socio economic condition. Under sustainable agricultural practices, with this study it is concluded that the FLDs programmes were effective in changing attitude, skill and knowledge of improved package and practices of HYV of lentil adoption.

The capital and operating costs of public facilities such as fish hatcheries can normally be assigned fairly easily; the benefits are, however, much more difficult to determine. Due to the availability of an extensive data base for a hatchery proposed for Lake Huron, an estimate of the benefits was obtainable and the benefit/cost ratio derived is in support of project construction.

Aims: The study examines the profitability of rice production, its key factors, and the consumption shares at household level. Study Design: A cross-section study design was used in this research. Place and Duration of Study: The study was conducted in the two Districts of Mbarali and Kyela in the Mbeya Region of Tanzania from January to March 2018. Methodology: Structured questionnaires were used to collect primary data from 240 small scale rice producers. Data analysis was performed by descriptive statistics and Farm Budgetary Techniques was used to calculate farm economic viability variables including profitability index, return on investment, capital turn over and benefit cost ratio. The Kendall’s coefficient of concordance was used to pinpoint and examine the key factors affecting rice profitability by farmers in the study area. Results: Descriptive statistics revealed that majority farmers have 45 years and below, 95.8% of the farmers are married. Majority (83.3%) households have family size of 2-4 individuals indicating shortage of family labor. About 80.8% of the respondents allocated farm size of 1-3 hectares. The budgetary farm technique revealed that average total cost, gross margin, and net farm income was 846450 (~ US $ 368.08), 1484175 (~US $ 645.41) and 1357975 (~US $ 590.73) Tanzania Shillings respectively. The profitability index, return on investment, capital turn over and benefit cost ratio for producers were 9.5%, 160, 2.6 and 3.1 respectively. According to Kendall’s coefficient of accordance, the identified main constraints for economic viability of rice production were weather variability, lack of access to irrigation services, rice price instability, lack of access to agricultural information and technology, and poor access to the key production inputs. Conclusion: It indicates that rice production is a profitable business in the study area and still there is potential for improving from the current yield. It was demonstrated that most of rice outputs are for commercial purposes with regards to consumption shares. This shows that rice is highly growing as commercial food crop in the Tanzania.

Bangladesh has an agrarian economy in which paddy is the dominant crop. A significant amount of field losses of paddy occurs every year due to natural calamities and a shortage of time during the harvesting period. During this study, a modification was done on locally developed BAU self-propelled reaper and its performance was compared with manual harvesting system of paddy. Several experiments were conducted in Boro paddy (April–May 2017) and Aman paddy harvesting (November–December 2017) at BAU farm of Bangladesh Agricultural University after necessary modification works in the workshop. An experiment was also conducted on Aman paddy in 2017 at BAU farm for determining manual harvesting cost. The technical and economic performances of the modified BAU self-propelled reaper were determined based on the field experiments. Results reveal that average fuel consumption, effective field capacity and field efficiency were 2.71 L/ha, 0.255 ha/h and 77.27%, respectively for the modified BAU self-propelled reaper and 2.88 L/ha, 0.25 ha/h and 75.76%, respectively for the existing BAU self-propelled reaper. These results indicated that field performances of modified BAU self-propelled reaper were better than that of the existing BAU reaper. Paddy harvesting cost was found 916 Tk/ha for modified BAU self-propelled reaper and 9200 Tk/ha for manual harvesting system. The benefit-cost ratio of the modified BAU self-propelled reaper was 2.18. Considering the technical and economic performances, modified BAU self-propelled reaper was found suitable than the existing BAU reaper.  So, the modified BAU self-propelled reaper may be introduced in Bangladesh in the commercial basis.J.

Proper sowing orientation and spacing are important factors for best crop growth. A field experiment was conducted to study the effect of different planting patterns with and without lentil intercropping on sugarcane growth and yield and farm economics. Each of these treatments were planted as sole crop and intercropped with lentil. Data were collected on plant cane and first ratoon crop. The maximum stripped cane yields (154.36 t/ha and 130.28 t/ha in plant and ratoon crop, respectively) were obtained from sugarcane planted at 120 cm trench planting both as sole as well as lentil intercropped. This treatment also attained 61% and 43% higher total sugar yields compared to traditional 60 cm single rows planting in plant and ratoon crops, respectively. Lentil intercropping did not have any significant effect on sugarcane yield, but trench planting at 120 cm with lentil intercropping had the highest lentil seed yield (598.0 in 2013–2014 and 629.8 kg ha−1 in 2014–2015) along with maximum land equivalent ratio (1.40 and 1.37), net return (Rs.321254/ha), net field benefit (Rs.491703/ha) and benefit cost ratio (2.01). Sugarcane at 120 cm trench planting with lentil intercropping also outperformed other planting patterns in improving economic returns.

School voucher programs have become a prominent aspect of the education policy landscape in the United States. The DC Opportunity Scholarship Program is the only federally funded voucher program in the United States. Since 2004 it has offered publicly funded private school vouchers to nearly four thousand students to attend any of seventy-three different private schools in Washington, DC. An official experimental evaluation of the program, sponsored by the federal government's Institute of Education Sciences, found that the students who were awarded Opportunity Scholarships graduated from high school at a rate 12 percentage points higher than the students in the randomized control group. This article estimates the benefit/cost ratio of the DC Opportunity Scholarship Program, primarily by considering the increased graduation rate that it induced and the estimated positive economic returns to increased educational attainment. We find a benefit to cost ratio of 2.62, or $2.62 in benefits for every dollar spent on the program.

Dungarpur is one of the most backward districts of Rajasthan (India) having 70.8 % of populations are tribal. Okra (Abelmoschus esculentus), Onion (Allium cepa L.) and Brinjal (Solanum melongena L.) are the three major vegetable crops grown in the district. Farm Science Centre known as Krishi Vigyan Kendra laid down front line demonstrations on these three vegetable crops under NAIP project by introducing improved and hybrid varieties and applying scientific package of practices in their cultivation. The productivity and economic returns of okra, onion and brinjal in improved technologies were calculated and compared with the corresponding farmer's practices (local checks). All the three vegetable crops recorded higher gross returns, net return and benefit cost ratio in improved technologies as compared to the plots where farmers were using traditional practices in their cultivation. It is suggested that location-specific integrated approaches would be needed to bridge the productivity gap of the vegetable crops grown in the district.

Increasing demand for maize in Nigeria has resulted in high use of inorganic fertilizers and these fertilizers are expensive for peasant farmers who dominate farming in the country. The use of inorganic fertilizers also results in hidden cost borne by man and the ecosystem. In a search for a cost-effective and safer alternative, six maize varieties were evaluated using moringa, banana-peel, maize-stalk fertilizer (MBM) both in solid and foliar forms. Gross benefit, net benefit and benefit-cost ratio (BCR) were used to determine enterprises with the highest economic returns. The results showed that maize varieties treated with 90 kg/ha of NPK had the highest grain yield which was significantly comparable with MBM. The application of 120N+50P+40K rate of MBM to single cross hybrid, SCH LY1312-1, resulted in the highest benefit-cost ratio (15.16). MBM is economically more viable than NPK Fertilizer and its application in the solid (powdered) form before planting produced double economic returns compared to foliar application. Single cross hybrids gave better economic returns when the fertilizer was applied in solid form.

An experiment was carried out in the farmer’s field at the MLT site Tularampur, Narail (AEZ-11) during the rabi season of 2011-12 to evaluate the performance of newly released mustard varieties to Zn fertilization. Three levels of zinc 2, 3 and 4 kg/ha from zinc sulphate was used in BARI Sharisha-14. The experiment was carried out in a tree with 6 dispersed replications. Response of mustard to zinc fertilizer was significantly evident for yield. The highest yield (1.42 t/ha) was obtained from T1(3 kg Zn/ha) which was statistically higher than T2 (4 kg Zn/ha) yielding 1.37 t/ha. Both the treatments gave higher yields over the control. From the economic analysis, the highest gross margin was observed (Tk. 47695/ha and Tk. 44595/ha) and highest benefit cost ratio (BCR) (1.57 and 1.45) obtained from T2 treatment followed by T3 treatment, respectively.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22037 J.
