Maize is gaining importance in recent years as a promising crop, but some constraints are intensifying with increased concern over input supply and soil-related environmental sustainability. So, we were interested to assess the financial profitability of maize production over the existing rice cropping system and factors responsible for changing land-use decisions in Northern Bangladesh. The comprehensive comparison revealed that maize farmers got higher returns than the farmers producing boro rice as the calculated BCR for the former (2.14) was higher than the later (1.29). The results of regression analysis showed that maize labor use, maize gross margin, availability of rice for home consumption, and the least rice-producing area had a significant effect on deciding to shift the land from rice to maize cultivation. Therefore, there was a great prospect of maize farming in the study area as a profitable enterprise.

Hybrid Maize

The present study is an attempt to assess the existing agronomic practices of hybrid maize cultivation, its profitability, constraints, and factors affecting hybrid maize production. The majority of the total farmers sowed seeds during the first week of December. The average seed rate was found to be 20.94 kg per hectare. About 16 varieties were found to cultivate by farmers, of which majority farmers used NK-40 followed by Pacific-II. All kinds of fertilizer used by the farmers were below the optimum level of recommendation. About 33 and 28 percent of the total variable cost was for human labour and chemical fertilizer, respectively. The average yield of hybrid maize was found higher than the national average. The average gross margin was observed to be Tk. 28456 on total variable cost basis. The cost per kilogram of maize cultivation was Tk. 4.12 and return from one kilogram of maize production was Tk. 7.80. It is found that the coefficient of human labour, land preparation, irrigation, urea and borax have significantly impact on gross return. Timely non-availability of seeds, high price of fertilizer, and low price of yield were the major problems for hybrid maize production. Farmers cultivated hybrid maize because of higher yield, higher income, and easy growing. Keywords: Gross return; gross margin; profitability. DOI: 10.3329/bjar.v35i1.5869Bangladesh J. Agril.

The study was carried out in four major maize growing areas namely Chuadanga, Dinajpur, Bogra and Lalmonirhat during 2006-2007 to know profitability level of maize production in Bangladesh. A total of 200 randomly selected maize growers taking 50 from each location were interviewed using pre-designed interview schedule. The average yield was found to be 8.00 t/ha. The average costs of maize production were Tk 44197, Tk 33195 and Tk 24441 per hectare on total cost, variable cost and cash cost basis respectively and gross return was Tk 69773 per hectare. The gross margin was Tk 36578/ha on total variable cost (TVC) and Tk 45332/ha on cash cost basis. The net return was observed to be Tk 25575 per hectare. Benefit cost ratios were calculated as 1.58, 2.10 and 2.85 on total cost, variable cost and cash cost basis respectively. As a result, maize cultivation was more profitable. Lack of capital and high price of TSP were the main constraints to its higher production.Key Words: Maize; production; agro-economic.DOI: 10.3329/bjar.v34i1.5748Bangladesh J. Agril.

Aim: This study was conducted to investigate the economic implication years after an outbreak of armyworm among the smallholding farmers in Ekiti State, Nigeria. Methodology: A combination of purposive and snowball sampling techniques were used to select 60 respondents in four communities of the State. Thematic information from the semi-structured questionnaire related to the socio-economic characteristics of respondents, their enterprise characteristics, farmers’ perception of significant constraints militating against maize production in the study area, as well as the efficacy of management strategies adopted by the respondents. Data was analyzed with descriptive statistics and Tobit regression. Results: The study revealed that maize farming was mostly on smallholdings owned by males within the active age of 35 years. These farmers practised mixed cropping system whereby maize is planted with other crops in a shifting cultivation pattern. Also, the respondents identified lack of inputs, lack of fund and credit facilities, climate change, disease and pest outbreak, inadequate storage and processing facilities, and imperfect information dissemination as significant constraints militating against self-sufficiency in maize production. The most debilitating of these constraints was the outbreak of the Fall armyworm, which ravaged maize farms. Information gathered revealed that higher percentages of the respondents combated this notorious pest with the use of synthetic chemicals alongside other management approaches. The result of the gross margin revealed that net return per hectare to maize production was N27, 510. The Tobit results revealed that only pests’ infestation in the previous year and age were significant with maize output loss. Conclusion: The Fall armyworm outbreak resulted in an economic downturn for maize farmers in Ekiti State.

AbstractA case study of the nopal-vegetable agroecosystem in metropolitan Mexico City was conducted to evaluate the crop's economic productivity and sustainability using economic, social, and environmental indicators. Economic indicators were based on a gross margin analysis, commercialization strategies, and provision of employment. Social indicators were education level, family size, origin of laborers, plot size providing a measure of equity, and social self-organization. Environmental indicators were soil nutrient content and fertilizer application, technological management, and crop and natural biodiversity. Information on relevant social, technological, and economic elements was obtained through structured interviews with 100 producers of the city's nopalproducing zone of Milpa Alta in the hills southeast of Mexico City. Analysis of soil samples from cropped fields at three different depths was conducted, along with a study of nopal-associated weed species used by the community. Net income per ha was equivalent to 4 minimum wages. Estimated scores of 89, 74, and 64 (on a scale of 0 to 100) were obtained for social, economic, and environmental sustainability indicators, respectfully, for this unique cropping system. Discussion focuses on trade-offs between indicators, the cost of achieving sustainability in the metropolitan zone of Mexico City, and appropriate policy responses.

Productivity  of  the  cropping  system  is  critical  to  the  food  security  of  Bangladesh.  However,  many concerns  about  the  sustainability  of  cropping  system  exist  because  of  lack of advance knowledge of farming.  In  this context,  a study  was  performed  in  the  agro-ecological  zone  of  the  Tista Mendar  Floodplain agro ecological zone (AEZ-3)  at  Jaldhaka subdistrict under Nilphamary district of  Bangladesh. By reorganization of existing cropping patterns (using Linear Programming Model) gross output (7% to 21%), gross margin (12% to 20%) and  labour employment (6% to 20%)have been increased from plan1(existing plan) to plan2 (by reorganization of existing lands). The cause of increase gross output, gross margin andlabour employment was some cultivated land from less efficient cropping patterns has been transferred to more efficient cropping patterns. Again, by reorganization of existing and improved cropping patterns, some lands of existing patterns have been shifted to improved cropping pattern.  As a result, gross out (17% to 31%), gross margin (27% to 32%) and labour employment (13% to 26%) have been raised from plan1 to plan 3 (by combination of improved technologies with existing technologies). The result of on farm demonstration showed gross output, gross margin and labour employment have been increased 24% to 53%, 32% to 51% and 12% to 47% from plan1 to plan 3, respectively. So, this study suggest, optimum farm plan with the combination of existing and improved cropping pattern will increase farm output and generate additional employment and improved food security.Progressive Agriculture 28 (3): 204-215, 2017

Land use planning as strategic instruments to guide urban dynamics faces particular challenges in the Global South, including Sub-Saharan Africa, where urgent interventions are required to improve urban and environmental sustainability. This study investigated and identified key challenges of land use planning and its environmental assessments to improve the urban and environmental sustainability of city-regions. In doing so, we combined expert interviews and questionnaires with spatial analyses of urban and regional land use plans, as well as current and future urban land cover maps derived from Geographic Information Systems and remote sensing. By overlaying and contrasting land use plans and land cover maps, we investigated spatial inconsistencies between urban and regional plans and the associated urban land dynamics and used expert surveys to identify the causes of such inconsistencies. We furthermore identified and interrogated key challenges facing land use planning, including its environmental assessment procedures, and explored means for overcoming these barriers to rapid, yet environmentally sound urban growth. The results illuminated multiple inconsistencies (e.g., spatial conflicts) between urban and regional plans, most prominently stemming from conflicts in administrative boundaries and a lack of interdepartmental coordination. Key findings identified a lack of Strategic Environmental Assessment and inadequate implementation of land use plans caused by e.g., insufficient funding, lack of political will, political interference, corruption as challenges facing land use planning strategies for urban and environmental sustainability. The baseline information provided in this study is crucial to improve strategic planning and urban/environmental sustainability of city-regions in Sub-Saharan Africa and across the Global South, where land use planning faces similar challenges to address haphazard urban expansion patterns.

SUMMARYYam minisett technique (YMT) has been promoted throughout West Africa since the 1980s as a sustainable means of producing clean yam planting material, but adoption of the technique is often reported as being patchy at best. While there has been much research on the factors that influence adoption of the technique, there have been no attempts to assess its economic viability under ‘farmer-managed’ as distinct from ‘on station’ conditions. The present paper describes the results of farmer-managed trials employing the YMT (white yam: Dioscorea rotundata) at two villages in Igalaland, Kogi State, Nigeria. One of the villages (Edeke) is on the banks of the River Niger and represents a specialist yam environment, whereas the other village (Ekwuloko) is inland, where farmers employ a more general cropping system. Four farmers were selected in each of the two villages and asked to plant a trial comprising two varieties of yam, their popular local variety as well as another variety grown in other parts of Igalaland, and to treat yam setts (80–100 g) with either woodash or insecticide/nematicide+fungicide mix (chemical treatment). Results suggest that while chemical sett treatment increased yield and hence gross margin compared with woodash, if household labour is costed then YMT is not economically viable. However, the specialist yam growers of Edeke were far more positive about the use of YMT as they tended to keep the yam seed tubers for planting rather than sell them. Thus, great care needs to be taken with planning adoption surveys on the assumption that all farmers should adopt a technology.
