The conversion from black tiger shrimp farming and crop farming to white leg shrimp production is widespread in Vietnam’s Mekong Delta provinces. However, this conversion trend also contains many risks related to the technical aspects of the production process. The study mainly aims to estimate the technical efficiency of white leg shrimp farming. It also compares the technical efficiency of white leg shrimp farming between the traditional group that historically has cultivated white leg shrimp and the group that recently converted from black tiger shrimp and crops to white leg shrimp, in order to evaluate the efficiency and adaptability of shrimp farming. Primary data were collected by directly interviewing 99 farmers in traditional areas and 101 farmers in recently converted areas in the study sites and analyzed by using the stochastic frontier method. The calculated technical efficiency was around 72.9 percent, suggesting that farmers could increase their output level by about 27.1%, given constant inputs. There was no difference in the technical efficiency of the two groups, indicating that the converted farms have sufficient adaptability when switching to white leg shrimp farming. The output loss in farmers’ production is still very high, with an average loss of 1973 kg/hectare.

Agriculture is the mainstay of Cameroon’s economy as it serves the purposes of food, livelihood and employment. Nevertheless, the country’s agriculture is plagued by low productivity and inefficiency in production. One of the main reasons for low productivity is the inability of farmers to fully exploit available technologies and production techniques. An important research question that comes to mind is, what are the major factors that hinder the technical efficiency of smallholder farmers? This study thus aimed to determine the level of technical efficiency in the production of tomato in smallholder farms, relying on primary data collected using a structured survey instrument administered to 80 tomato farmers in the Buea municipality of Cameroon. Data was analyzed using descriptive statistics and a stochastic frontier analysis method in the Cobb-Douglas production function. The STATA.14 software was used to obtain both stochastic frontier estimates and the determinants of technical efficiency. The results indicate that farmers are not fully technically efficient with a mean technical efficiency score of 0.68 with one farmer operating on the frontier. The study also revealed that most of the farmers irrespective of the size of the holdings have shown technical inefficiency problems. The older farmers were observed with the best measures of technical efficiency. Education, age and the adoption and practice of agronomic techniques had a positive and significant influence on technical efficiency while the nearest distance to the extension agent had a rather negative influence on technical efficiency. The input-output relationship showed that the area of tomato cultivation and the quantity of improved seed used were positive and significantly related to output at the 5% level of probability. As a result, it is recommended that farmers should increase their farm size, use of improved seeds and the adoption and practice of novel techniques in production. More emphasis should be placed on extension agents as they have a significant role to play in terms of improving and augmenting farmers’ education and information base through on farm demonstrations and result oriented workshops as all this will ensure increased production and productivity thereby increasing technical efficiency and achieving food self-sufficiency.

This study employed a Cobb-Douglas stochastic production frontier function to estimate the level of technical efficiency. The results of the analysis showed that cropping season of mango growers have been round year. Difference of the study compared to past researches related to tropical fruits analyzed efficiency of three seasons instead of only focusing on efficiecy of one seasson or total a year. The findings revealed that season 3 ranked first in terms of technical efficiency (58.2%), follwed by season 1 (53.6%) and then season 2 (49.2%). Moreover, the input variables that explained technical efficiency were were fertilizer (root), fertilizer (leaf) and labor in season 1; pesticide, fertilizer (leaf) and labor in seaon 2; and pesticide, fertilizer (root), fertilizer (leaf) and labor in in season 3. In addition, major determinants of socioeconomic characteristics influenced positively on technical efficiency were were plant density and land area in season 1 and season 3; market access, plant density and land area in season 2. Likewise, the constraints to mango production were wrapping bag and classifying sale in season 2, and age and wrapping bag in season 3.

The aims of this study are to measure the technical efficiency (TE) of Cambodian household&rsquo;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&rsquo;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&rsquo;s rice production, while disaster, education of household head, family size and other crops&rsquo; 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.

There is a retarded growth in poultry egg production in Ogun state, Nigeria. This has led to high cost of production and the average market prices of the product. The study therefore examined the technical efficiency of poultry egg production in Ogun state, Nigeria using the stochastic frontier production function model. Primary data were collected using a set of structured questionnaire from one hundred and twenty (120) poultry egg farmers who were selected using multi-stage sampling techniques, from Poultry Association of Nigeria, Ogun State chapter. The level of technical efficiencies (TE) varied widely across farms, ranging between 64 percent and 97 percent, with a mean value of 85.6 percent. Only years of experience negatively affected the TE while an increase in other socio-economic variables, such as education, age and location of farm led to an increase in the TE value. The major constraints in poultry egg production ranked in order of unbearable cost of feed, inadequate fund and capital, lack of disease control facilities and unstable power supply. This study recommends dissemination of improved modern technology in egg production to the poultry egg farmers.

<strong>Indonesian</strong><br />Defisit produksi gula dalam negeri antara lain disebabkan oleh rendahnya produktivitas usaha tani tebu. Peningkatan efisiensi teknis dapat menjadi solusi untuk meningkatkan produktivitas dan pendapatan petani. Penelitian ini bertujuan untuk menganalisis efisiensi teknis usaha tani tebu dengan metode MLE stochastic frontier production function. Data primer diperoleh dari 61 contoh yang dipilih secara acak dari populasi petani tebu di pabrik gula Pakis Baru dan Trangkil di Kabupaten Pati pada April-Mei  2018.  Analisis menunjukkan bahwa efisiensi teknis dan pendapatan usaha tani tebu dengan sistem benih baru lebih tinggi daripada dengan sistem kepras. Penggunaan pupuk kimia sudah berlebihan. Keanggotaan kelompok tani berdampak signifikan dalam meningkatkan inefisiensi pada sistem benih baru, sedangkan keanggotaan dalam koperasi berpengaruh signifikan dalam menurunkan inefisiensi pada sistem benih baru. Jumlah anggota keluarga berpengaruh signifikan dalam mengurangi inefisiensi teknis sistem kepras.  Efisiensi teknis dan pendapatan usaha tani tebu dapat ditingkatkan melalui optimasi penggunaan sarana produksi dengan mematuhi rekomendasi pabrik mitra dan pemerintah, khususnya penggunaan pupuk sesuai dosis rekomendasi dan penggantian ratun yang sudah berumur tiga tahun dengan benih baru bermutu tinggi sesuai agroekosistem spesifik lokasi. Untuk itu, penyediaan layanan penyuluhan yang efektif merupakan syarat keharusan. <br /><br /><br /><strong>English</strong><br />Domestic sugar production deficit is partly caused low productivity of sugarcane farming. Improving technical efficiency may increase farm productivity and income. The study aims to analyze the sugarcane farming technical efficiency by using the stochastic frontier production function. The primary data were obtained from 61 randomly selected samples of sugarcane farmers population of the Pakis Baru and Trangkil sugar factories in Pati Regency in April-May 2018. The study shows that the sugarcane farming technical efficiency and income of the new sugarcane seed system is higher than the ratoon system. Chemical fertilizers have been over used.  Farmer group membership significantly increases inefficiency of the new sugarcane seed system, while the cooperative membership significantly decreases inefficiency of the new sugarcane seed system. Family member significantly decreases technical inefficiency of the ratoon system. Technical efficiency and farmers’ income can be improved by allocating production inputs in efficient manner based on the recommendations of partner Sugar Factory and Government, of in particular, fertilizer utilizations according to the recommended dosages and replacement of the already three years ratoon seeds with new high-quality seeds in accordance with the local agroecosystem condition. To this end, provision of an effective extension service is imperative.

The main objective of this study is to explore the major impacts of salinity intrusion on coastal agriculture and farmer’s livelihoods in Bangladesh. The study has attempted to identify some effective measures for the sustainability of coastal agriculture. The study was conducted based on both primary and secondary data during 2010-2020. To collect primary data, a total of 150 respondents out of 240 households were randomly interviewed and samples are drawn proportionately from study sites. Descriptive and inferential statistics have been done to analyze data. The ArcGIS mapping tool was adopted to represent the spatio-temporal change of saline area. It reveals that due to high salinity intrusion the coastal agriculture has already experienced noticeable adverse impacts especially in increasing rate of salinity, loss in cultivable land and production. Shrimp farming with brackish water and tidal inundation are explored as the main causes for salinity intrusion. In study sites, the level of salinity in 2020 is much stronger than in 2010. It reveals that due to strong salinity in agricultural land the farmer's are suffering from low income, unemployment, scarcity in irrigation and freshwater. It was identified that the planned shrimp culture, management of the embankment, cultivation of saline tolerant crops and raising public awareness will be the possible measures to control the intrusion of salinity. Therefore, it is expected that the evaluation of the revealed impacts of salinity intrusions and the explored measures will be effective to ensure the sustainability of coastal agriculture in Bangladesh.

SUMMARYGiven the importance of irrigation for rice production, this study compared the technical efficiency of irrigated and rain-fed rice (Oryza sativa) farms in the Upper Niger River Basin and Rural Development Authority (UNRBDA), Nigeria. Primary data were collected from 300 irrigators and 325 rain-fed rice producers. Applying the stochastic frontier Cobb–Douglas production function, net income analysis and Likert scale rating techniques, the study found that irrigated scheme increased marginal factor productivity and profitability. The study revealed the existence of large technical inefficiency in rain-fed farms when compared with irrigated farms. This suggests that there is room for output gains through technical efficiency improvement in the rain-fed system. The mean value of the marginal physical product of inputs (VMPPX) in the irrigated farms (₦2.32) was more than that of rain-fed farm (₦1.67). Thus, if the average producers in the rain-fed are to achieve the technical efficiency level of the average producer in the irrigated farms, they can realize 38% output gains. Similarly, the mean net farm income (NFI) of ₦62,280.00 per ha in the irrigated farm was more than double of that of rain-fed farms ₦22,391.00. The partial regression coefficients for the individual production factors (β1) and (β3) for labour input (X1) and other variable inputs (X3), respectively, were positive and significant at 1% level, suggesting that the partial elasticity of crop output with respect to labour and other costs was higher in the irrigated farms than in the rain-fed farms. The Likert scale rating techniques showed that the poor knowledge of irrigation techniques, insufficient water for irrigation during the dry season, high cost of labour and lack of access to credit were the critical constraints preventing the rain-fed rice producer from joining the irrigation scheme. In view of this, rice irrigators should be encouraged to train more rain-fed farmers on some rudiments of irrigation techniques. They should also be linked to the sources of finance. Water Users Association (WUA) should be established in communities within the scheme areas for effective communication between farmers and the officials of the UNRBDA. Decision on the allocation of resources to Fadama sites including water should be given to WUA to strengthen the membership of the organization, while the government officials serve as supervisory and advisory body.
