The traditional approach to modeling productive efficiency assumes that technology is constant across the sample. However, farms in different regions may face different production opportunities, and the technologies they employ may differ due to environmental factors. Therefore, rather than using a traditional stochastic frontier model in such cases, a stochastic meta-frontier (SMF) analysis is recommended to account for environmental factors between regions. It follows that differences in environmental factors between the upland and lowland regions in Anambra State, Nigeria, may result in farmers producing rice under different production and environmental conditions. Using the SMF model, this study, for the first time, determines technical efficiency (TE) and technological gap ratios (TGRs) of rice production from the upland and lowland regions in the Awka North Local Government Area of Anambra State, Nigeria. Our data are from a cross-section sample of randomly selected rice farmers. Results reveal that lowland regional rice producers are on average, significantly more technically efficient (91.7%) than their upland counterparts (84.2%). Additionally, mean TGRs associated with lowland rice farmers are higher (92.1%) than their corresponding upland producers (84.7%). While the upland rice producers are less technically efficient and further away from their full potential, results indicate that both sets of farmers do not use advanced technologies to match the industry’s potential. We suggest that agricultural policy should focus on providing regionally specific technologies, such as improved rice varieties that fit the working environment of the lagging area, to help rice farmers improve their resource efficiency and minimize technological gaps.

The aims of this study are to measure the technical efficiency (TE) of Cambodian household’s rice production and trying to determine its main influencing factors using the stochastic frontier production function. The study utilized primary data collected from 301 rice farmers in three selected districts of Battambang by structured questionnaires. The empirical results indicated the level of household rice output varied according to differences in the efficiency of the production processes. The mean TE is 0.34 which means that famers produce 34% of rice at best practice at the current level of production inputs and technology, indicates that rice output has the potential of being increased further by 66% at the same level of inputs if farmers had been technically efficient. Furthermore, between 2013-2015, TE of household’s rice production recorded -14.3% decline rate due to highly affected of drought during dry season of 2015. Moreover, evidence reveals that land, fertilizer, and pesticide are the major influencing input factors of household’s rice production, while disaster, education of household head, family size and other crops’ cultivated area are core influencing factors decreasing TE. Conversely, the main influencing factors increasing TE are irrigated area, number of plot area and sex of household head.

This study estimated technical efficiency levels of cereal crops producers. The study employed the translog stochastic frontier model to estimate efficiency levels of maize, rice and sorghum producers in the survey area. Findings revealed that maize and sorghum farmers were operating in the efficiency range of 0.50 to 0.98, while for rice farmers efficiency estimates ranged between 0.71 and 0.98. Fur- thermore, it was also observed that a majority of the rice farmers operate in the range 0.91 and 0.98 efficiency levels. Also, about 18% of the farmers operate in the efficiency range of 0.81 and 0.90, while just about 14% operate in the range of 0.96 and 0.98 efficiency levels for rice production. Findings suggest that, all things been equal, most of the cereal crops producers could improve their current levels of production by adjusting their input combination.

AbstractProfitability of rice production in different production systems in Ebonyi State, Nigeria was evaluated. Rice is critical for food security in Nigeria, hence, farmers need to make appropriate choices of rice production systems to optimize production and ensure an adequate domestic supply. This study used 2015 survey data from rice farming households. Rice farmers in swamp, lowland and upland rice production systems showed variability in profit. Swamp production systems had the highest return per hectare (29.37%) followed by lowland production systems (20.10%) and upland production systems (13.03%). Poor access to production credit and climate change were constraints to rice production in the area. Rice production using the swamp production system is profitable and would ensure increased production and higher returns to the farmers. It is recommended that farmers should form cooperative groups to enable them to pool resources together to boost their production.

A socio-economic study was carried out in two rice production environments (Gazipur and Tangail) to assess the comparative advantages of using urea super granule (USG) over prilled urea (PU) in modern rice production and to examine the differences in producers’ technical efficiency between USG user and non- user in crop management. Stochastic frontier production model was employed to examine the farm specific technical efficiency difference in crop management between USG and PU users in the study areas. Analysis revealed that comparatively low amount (36%) of urea was needed in modern boro rice production using USG instead of PU. Nearly 366 % more labour was needed in the USG using plots compared to that of PU user plots, while weeding cost was a bit lower in USG using plots. Analysis also indicated that the sample farmers were able to achieve additional yield of 0.87 t/ha by using USG and this yield gain further resulted to additional benefit of Tk. 11506/ha. For the resource poor rice farms, this benefit is considered to be substantive. Farmers’ contact with the technology disseminators, training on rice production and the use of USG (instead of PU) were the important factors of increasing rice farmers’ technical efficiency in crop management and productivity enhancement as well. According to the farmers’ opinion, there were several constraints in using USG and out of those, requirement of more labour and non availability of USG in proper time were the dominant ones.

Upland rice grown by rice farmers is having the lowest productivity in the rice production system. Drought stress is the most severe abiotic constraint for upland rice. The improvement of rice productivity in such ecosystems is essential to meet the food security needs of the population. Therefore, the cultivation of drought tolerant rice is becoming an increasingly important task. Numerous minor traits have been proposed to assist plant breeders in their selection, but most of these traits are not used in breeding because they are not practical for breeding purposes, have low heritability, or are not very correlated with grain productivity. There has been shown, that standardization of drought screening improves heritability under stress to the values similar to those obtained for the yields under well-watered conditions. Nowadays there has now been proven that drought-resistant varieties can be developed by direct selection for productivity under stressful conditions. Currently, there have been identified many quantitative trait loci (QTL) of drought tolerance in rice, but only a few of them are suitable for use in marker breeding. However, the identified genes of great drought tolerance can be effectively used in breeding for drought tolerance. The use of molecular markers will improve the efficiency of breeding work. The current review has briefly considered the importance of rice, its various production systems, and the impact of drought stress on rice production. There have been discussed the physiological mechanisms contributing to the maintenance of grain productivity under drought conditions, and there have been analyzed the breeding methods for improvement of drought resistance.

The intermittent and widespread occurrence of drought in rainfed upland rice fields across sub-Sahara Africa has led to tremendous decrease in food security in the region. Although high yielding, drought tolerant varieties have been developed over years to mitigate this trend, limited adoption had been recorded for most of these materials. This study investigated farmers’ perceptions on drought stress and their preferred traits in new upland rice varieties across two major upland rice growing states in Nigeria. Participatory Rural Appraisal was conducted among 119 rice farmers using comparative approach, probing and semi structured interviews. Result based on farmers knowledge of changes in rainfall pattern and preferred traits such as plant architecture and grain shapes in a new upland rice variety differed significantly across the two state. The results identified drought stress as one of the main constraints to upland rice production across communities. The ideal upland rice variety desired by most respondents in both states should be of medium plant height (115-130cm) characterized by white, long and bold grains. This study has demonstrated the importance of understanding farmer’s desired traits in a new upland rice variety and the need to incorporate identified traits in creation of resilient new upland rice varieties adaptable to rain-fed upland rice growing regions of Nigeria.

The development of rice irrigated farming is constrained by the conversion of land agricultural to non-agricultural. Therefore, policy to develop upland rice production in dryland and rainfed lowland is increasingly being implemented. Efforts to expand the application of technological innovations as a lever of upland rice production have intensified by introducing new superior varieties of upland rice. This research aims to analyze farmers' attitudes and satisfaction levels with introducing upland rice to attributes based. The location of this research is in Tegalgiri Village, Nogosari District, Boyolali Regency. Primary data were obtained through a survey method of 35 farmers who planted the Rindang 1, Rindang 2, Inpago 10, and Inpago 12 varieties. Farmer attitudes were analyzed using the Fishbein Multi-attribute Model, while farmer satisfaction level was analyzed using the customer satisfaction index (CSI). The results are the attributes "production" and "resistance to pests and diseases" were agronomic performance which was the most essential and primary consideration for farmers in choosing varieties. Farmers have a positive attitude towards the four new superior varieties. The meaning is that farmers want to adopt and plant the new superior varieties of upland rice. Farmers' satisfaction levels are in the "satisfied" to "very satisfied" category of the four new superior varieties. Hopefully, the new superior upland rice varieties that were introduced can be a choice of varieties by farmers.   Keywords: atributtes, farmer’s attitude, satisfaction level, upland rice, superior varieties

Rice is an important staple food in many developing countries, especially in Senegal. However, rice production in Senegal only meet 20% of the domestic demand largely due to the poor performance of rice farmers and low productivity. Access to agricultural credit has strong impacts on the technical efficiency of farmers and would promote inputs and new technology adoption. But that is not clear enough in previous studies. This study investigates the impact of agricultural credit access on rice productivity and technical efficiency with 260 random sampled rice farmers from Anambe basin in Senegal. The Stochastic Frontier Analysis (SFA) was adopted to estimate the technical efficiency. The results indicate that the inputs of rice production, including labor, pesticide, herbicides and fertilizer, have significant impacts on rice productivity. Furthermore, the results present that the average efficiency is of 0.813 and the inefficiency estimation model reveals that the influences of agricultural credit access, gender, education, ethnicity, use of improved seed and land tenure system on technical inefficiency of rice production are significant. Particularly, for the access to agricultural credit, rice farmers without agricultural credit would get 3.8% higher production inefficiency. The farmers with access to credit yield 37.32% higher rice production than their counterparts. Therefore, our study provides strong empirical evidence to promote agricultural credit in rice production.

Farmers have been encroaching fragile wetlands as a strategy to increase their rice production thus threatening wetlands’ existence and capacity to other critical ecosystem services. This calls for efficient production to strike the balance between food rice production and wetlands’ sustainable existence. The current study sought to provide assess rice farmers’ technical efficiency of resource use by detecting the determinants of rice yield and further identify the determinants of technical efficiency of the resources used by rice farmers in Kilombero wetland. A cross-sectional survey of 145 randomly sampled farmers aided in achieving the study objective. A stochastic frontier analysis (SFA) model was used to analyze data. The mean technical efficiency among farmers was at 60.54% level. The positive determinants of rice yield were land and fertilizers while labor influenced it negatively. Age, education, farming experience, group membership, and credit access reduced inefficiency while the distance to the extension agent and off-farm income increased farmers’ inefficiency. The study concludes that there is a possibility of expanding rice production without threatening the wetland’s existence. It recommends that government and other stakeholders to ensure that rice farmers are up-to-date with optimal use of fertilizers in rice production since it will assist in improving rice yield while the rate of expansion of rice lands in the wetlands will lower. Policy implementers ought to establish initiatives that inspire rice farmers to capitalize on farmer groups and join education programs to take full advantage of their potential efficiency and might participate in community development activities.
