Résumé : Ce papier analyse l’effet de l’efficience productive de la fonction publique sur la croissance économique dans les pays de l’UEMOA de 2003 à 2017. Pour ce faire nous avons estimé d’abord les scores d’efficience productive par la méthode d’enveloppement des données (DEA) puis, régressé le taux de croissance économique sur les scores d’efficience productive des fonctions publiques par la méthode des variables instrumentales. Les résultats nous montrent que les scores d’efficience productive expliquent positivement la croissance économique dans les pays de l’UEMOA. Ces résultats suggèrent des politiques économiques d’amélioration de l’efficience productive des fonctions publiques pour stimuler la croissance économique dans l’UEMOA. Mots clés : Efficience productive - Fonction publique - Croissance économique - DEA. 4 Effect of the productive efficiency of the public service on economic growth in WAEMU: A two-step approach Abstract: This paper analyzes the effect of the productive efficiency of the public service on economic growth in the WAEMU countries from 2003 to 2017. To do this, we first estimated the scores of productive efficiency by the Data Envelopment Analysis (DEA) method, then we regressed the rate of economic growth on the productive efficiency scores of public services by the method of instrumental variables. The results show that the productive efficiency scores positively explain economic growth in the WAEMU countries. These results suggest economic policies to improve the productive efficiency of public services to stimulate economic growth in the WAEMU. Keywords: Productive efficiency - Economic growth - Public service - DEA. J.E.L. Classification : D24 – D73 – H83 – O43 – O47.

RÉSUMÉ Au milieu des années quatre-vingt, les sociétés africaines d’électricité se sont engagées dans des programmes de réforme ayant pour objet d’améliorer leur efficience productive. Douze de ces réseaux sont étudiés dans cet article. Des frontières de production paramétriques sont d’abord estimées sur données de panel. La société ivoirienne, dont la privatisation a été effectuée en 1990, révèle que cette réforme institutionnelle a aidé à accroître la performance productive tandis que le même résultat a été difficile à obtenir lorsque l’opérateur est resté totalement public. Une analyse plus détaillée du cas ivoirien est ensuite réalisée en considérant des frontières de type DEA. Des indices de Malmquist non paramétriques sont calculés. Ils prennent en compte les dimensions économiques et sociales de l’activité du service public. L’output multiple est notamment mesuré par l’électricité produite (kWh) et le nombre de consommateurs. Une diminution de la productivité totale des facteurs (PTF) est mise en évidence, dont l’effet est principalement imputé au mouvement de l’efficience technique. On conclut sur le rôle potentiel de la régulation publique pour faciliter la compatibilité entre l’accès au service universel et l’objectif de profit.

La vache allaitante utilise près de 70% de l’énergie qu’elle ingère pour son besoin d’entretien. L’importance de cette dépense non productive détermine fortement son efficience d’utilisation de l’énergie. Les nouvelles recommandations alimentaires de l’INRA permettent de mieux quantifier cette dépense non productive afin d’en maîtriser les principaux facteurs de variation. Une base de données a été constituée en regroupant 30 expérimentations, présentant notamment des niveaux alimentaires contrastés (soit au final 101 traitements expérimentaux), menées en stations expérimentales avec des vaches allaitantes. L’Énergie des dépenses non productives (EDNP) exprimée en énergie nette (UFL) a été calculée pour chaque traitement comme la différence entre l’énergie nette ingérée et celles des besoins de lactation, de gestation, et des variations de la masse corporelle par estimation de sa composition chimique. La production de lait moyenne est de 8 kg/jour et prioritaire, quel que soit le niveau alimentaire subit. Estimée par sa composition chimique (respectivement 37 et 21% de lipides), la valeur énergétique de la variation de poids s’élève en moyenne à 2,4 UFL/kg pour les multipares et 1,8 UFL/kg pour les primipares. Les dépenses non productives peuvent s’estimer à partir d’une seule équation dont les variables sont le besoin d’entretien (Eentretien), les conditions d’activité (Iact), la variation de poids (ΔPV) et l’état initial au vêlage (NEC) : EDNP = (Eentretien x Iact) + (0,0073 x ΔPVc x NEC). Le terme interférant (ΔPVc x NEC) traduit les adaptations du métabolisme en situation nutritionnelle contraignante ou pléthorique. Cette quantification nouvelle de l’épargne énergétique associée à la baisse des apports (ou l’inverse) permettra aux éleveurs de mieux gérer l’alimentation de leurs vaches. Les variations de dépenses non productives et leurs nombreux facteurs de variation devront devenir la cible des recherches dans les années à venir.

This study examines the determinants of productive efficiency of banks operating in 8 member countries of the Association of Southeast Asian Nations (ASEAN). This study uses the economic theory approach to examine the existence of economies of scale on the ASEAN banking market, especially its impact on cost efficiency. The author applies a concept of average cost (AC) as a proxy for the productive efficiency. He finds that economies of scale exist on the banking market and economies of scale and scope should be considered in the industrial policy. Stronger capital position is also positive to banks’ efficiency and means that stronger capitalized banks are more efficient. Bank that remunerates better tends to be more efficient as a result of economic capital effect.

The present paper estimates the technical, allocative and economic efficiency of tomato growers. The study was conducted in two villages, namely, Tarnab and Akbarpura of the District Peshawar, the Khyber Pakhtunkhwa province, Pakistan. The data were collected by conducting a farm level survey of 300 tomato growers in the study area. The findings show that there was a big gap between the maximum and minimum technical efficiency indices, with an average technical efficiency index of 66%. There was also a huge gap between the highest and the lowest index of allocative efficiency of tomato growers. Economic efficiency indices also varied significantly. The study concluded that the farmer education, extension visits, age and access to credit were the significant determinants of these efficiencies. One of the most important policy implications of this study is that there is enough potential to increase the present level of efficiencies for tomato production in the study area.

The impacts of zero tillage (ZT) on soil physical, biological, and chemical properties have been fairly documented in the literature. However, there is still an information gap in the developing world in general and in integrated crop–livestock production systems in dry areas of the world in particular. Using a sample of 621 farmers in Syria, this study assessed the implications of adoption of ZT technology on productive efficiency, input-specific resource use efficiency, and production risk. A stochastic production frontier model, which explicitly and simultaneously accounts for technical inefficiency and production risk, was used to estimate total factor and input-specific technical efficiencies and the risk of obtaining lower levels of yields for each of the sampled farms. Model results show that adoption of ZT proved to be an effective risk management strategy in this dryland production system, where it led to 95% and 33.3% reductions in the risk of obtaining wheat yield levels below 1000 kg/ha and 1500 kg/ha, respectively. Overall, the results have a clear indication that using ZT leads to improvements in productive efficiency as the adoption of ZT led to 93% reduction in the risk of obtaining efficiency levels below 40%. Future research will be needed to shed light on whether coupling ZT with the other components of conservation agriculture will reverse some of these effects.

This paper presents the results of stochastic parametric approach used in estimation of production frontier. The estimation of output oriented technical efficiency was based on the Stochastic Frontier analysis with Cobb-Douglas production function. The model also included a dummy variable which expressed production conditions in which Slovak farms are operating. We divided farms into two groups regarding production conditions: productive regions (PR) and less favorable area (LFA) regions. The data set included 79 Slovak farms operating in different regions in the 2003–2005 time periods. The following input variables are included in the model: capital, material, labour and agricultural land according to the LPIS system. Total output was used as the output variable. From the achieved results, we can conclude that the significant statistical differences in average technical efficiency were detected only in year 2005 between the farms of the mentioned production conditions. A higher level of variability in technical efficiency was detected in farms operating in productive regions compared to technical efficiency of farms in the LFA regions.

This paper estimates a stochastic production frontier based on experimental data of cereals production in Finland over the period 1977-1994. The estimates of the production frontier are used to analyze nitrogen and phosphorous productivity and efficiency differences between soils and crops. For this input specific efficiencies are calculated. The results can be used to recognize relations between fertilizer management and soil types as well as to learn where certain soil types and crop combinations require special attention to fertilization strategy. The combination of inputs as designed by the experiment shows significant inefficiencies for both N and P. The measures of mineral productivity and efficiency indicate that clay is the most mineral efficient and productive soil while silt and organic soils are the least efficient and productive soils. Furthermore, a positive correlation is found between mineral productivity and efficiency. The results indicate that substantial technical efficiency differences between different experiments prevail.;

Agricultural productive services provide a new entry point to solve the “labor dilemma” and contributes to the sustainable development of the apple industry. In this study, we establish a random frontier model with the Translog production function to analyze the influence of productive services on the technical efficiency of apple production based on a microscopic survey data of 661 apple farmers. The results indicate that the purchasing proportions of productive services are obviously different among the different links of apple production, while those among different regions are not obvious. Overall, productive services have a positive effect on improving the technical efficiency of apple production, but productive services in different links have a different effect; specifically, productive services in the bagging link have a positive effect on the technical efficiency of apple production, productive services in the pest controlling link have a negative effect, and productive services in other links have no significant effect. We suggest that policymakers should promote the orderly development of agricultural productive services, focus on improving the popularity of productive services in bagging links, and improve the quality of productive services in the pest control link.

Purpose The purpose of this paper is to measure technical efficiency of Indian thermal power sector employing the recent by-production approach. Design/methodology/approach The by-production approach is used in conjunction with data from the Central Electricity Authority (CEA) of India to compute the output-based Färe, Grosskopf, Lovell (FGL) efficiency index and its decomposition into productive and environmental efficiency indexes for the ITPPs Findings The authors show that given the aggregated nature of data on coal reported by CEA, CEA’s computation of CO2 emissions through a deterministic linear formula that does not distinguish between different coal types and the tiny share of oil in coal-based power plants, the computed output-based environmental efficiency indexes are no longer informative. Meaningful measurement of environmental efficiency using CEA data is possible only along the dimension of the coal input. Productive efficiency is positively associated with the engineering concept of thermodynamic/energy efficiency and is also high for power plants with high operating availabilities reflecting better management and O&M practices. Both these factors are high for private and centrally owned as opposed to state-owned power-generating companies. The example of Sipat demonstrates the importance of (ultra)supercritical technologies in increasing productive and thermodynamic efficiencies of the ITPPs, while also reducing CO2 emitted per unit of the net electricity generated. Originality/value This paper uses the by-production approach for the first time to measure technical efficiency of ITPPs and highlights how the nature of the Indian data impacts on efficiency measurement.

To increase shallot production in Indonesia is faced with the issue of the dichotomy between Java and outside Java. Data shows that more than 70% of shallot harvested area is on Java, even though it is only 17% of Indonesia's total agricultural area. This research aims to identify factors that determine shallot production and measure the technical efficiency of shallot production and its determining factors. We used survey data from the Central Bureau of Statistics in 2014, which consisted of 2,860 input-output units of shallot production on Java and 940 outside Java. Using the stochastic frontier production function, it is found that production factors of land, labor, seeds, fertilizers and pesticides significantly determine shallot production in Java and outside Java. The marginal productivity of land, labor, seeds, fertilizers and pesticides in Java is higher than outside Java. The average technical efficiency score of production outside Java is higher than in Java. However, land productivity outside Java is lower than in Java. These findings indicate that the majority of shallot farming outside Java is already at its production frontier, whereas in Java only a small portion has reached its production frontier. Technical efficiency of production is determined by season and type of land, as well as farmers' membership in farmer groups, partnerships, and cooperatives. This conclusion implies that increasing shallot production outside Java requires new technology that can increase marginal input productivity. Technology to be developed is the use of true shallot seeds, accompanied by irrigation and agricultural institutions.

ABSTRACT In an environment where individual productivity can be increased through efforts directed at a conventional task approach and more efficient task approaches that can be identified by thinking outside-the-box, we examine the effects of productivity-target difficulty and pay contingent on meeting and beating this target (i.e., target-based pay). We argue that while challenging targets and target-based pay can hinder the discovery of production efficiencies, they can motivate high productive effort whereby individuals work harder and more productively using either the conventional task approach or more efficient task approaches when discovered. Results of a laboratory experiment support our predictions. Individuals assigned an easy productivity target and paid a fixed wage identify a greater number of production efficiencies than those with either challenging targets or target-based pay. However, individuals with challenging targets and/or target-based pay have higher productivity per production efficiency discovered, suggesting these control tools better motivate productive effort. Collectively, our results suggest that the ultimate effectiveness of these control tools will likely hinge on the importance of promoting the discovery of production efficiencies relative to motivating productive effort. In doing so, our results provide a better understanding of conflicting prescriptions from the practitioner literature and business press.

Abstract The need to complement the supply of animal products with other sources of poultry necessitates exploring the potentials of domestic duck production. Studies conducted on indigenous ducks in Nigeria have paid less attention to the resource requirements and its determinants to duck production. This study therefore estimated technical efficiencies of domestic duck producers in South-western Nigeria, and identified some socio-economic factors, which influence them. A combination of purposive and random sampling was employed. Stochastic frontier production function approach using a translog production function was used to estimate the technical efficiencies of indigenous duck producers, while inefficiency model was used to determine the socio-economic factors affecting the technical efficiencies. The results showed that the level of technical efficiency ranged from 48% to 96% with a mean of 83.3%, which suggests that average duck output was 16.7% short of the maximum possible level. This implies that productive efficiency could still be improved using the subsisting resource base. The study concluded that mounting capacity building programmes for duck farmers generally, and availability of credit could increase the productivity of duck enterprise if monitored.

The company focuses on producing quality products by implementing the Toyota Production System, known as TPS. The current constraint is the absence of maintenance on the Leak Test, thereby reducing production profits caused by high engine damage. This also causes the average repair time for the Leak Test Model 4L45W engine to be above the repair target set by the company, where the company targets an average repair time per month of 12 minutes. For this reason, corrective steps are needed so that the production process runs smoothly according to operational standards. This step involves proposing the implementation of Total Productive Maintenance (TPM). It is known that the average Overall Equipment Effectiveness (OEE) Leak Test machine in June–August was 60.09%. The Japan Institute of Plant Maintenance (JIPM) stipulates that if the OEE value is equal to 60%, it indicates that there is a lot of room for improvement. After implementing Total Productive Maintenance (TPM) on the Leak Testin September, the OEE value rose to 94.33%, and the average monthly repair timemet the company's target of 9.2 minutes. This greatly affects the cost of production due to lower production costs due to overtime. This indicates improvement, and the first step in the proposed implementation of the Total Productive Maintenance Machine Leak Test model 4L45W is said to be successful

Energy transformation powers change in the universe. In physical systems, maximal power (rate of energy input or output) may occur only at submaximal efficiency (output/input), or conversely, maximal efficiency may occur only at submaximal power. My review of power and efficiency in living systems at various levels of biological organization reveals that (1) trade-offs (negative correlations) between power and efficiency, as expected in physical systems, chiefly occur for resource-supply systems; (2) synergy (positive correlations) between power and efficiency chiefly occurs for resource use systems, which may result from (a) increasing energy allocation to production versus maintenance as production rate increases and (b) natural selection eliminating organisms that exceed a maximal power limit because of deleterious speed-related effects; (3) productive power indicates species-wide ‘fitness’, whereas efficiency of resource acquisition for production indicates local ‘adaptiveness’, as viewed along a body size spectrum and within clades of related species; (4) covariation of the power and efficiency of living systems occurs across space and time at many scales; (5) the energetic power/efficiency of living systems relates to the rates and efficiencies/effectiveness of nutrient/water uptake/use, the functional performance of various activities, and information acquisition/processing; and (6) a power/efficiency approach has many useful theoretical and practical applications deserving more study.

This research's objective aims to determine the factors of production that influence siam oranges production and to analyze the efficiency of production factors on siam orange farming in Batang Hari Regency. In this research, a restriction was conducted on the analysis of the factors that affect the production of siam oranges, that productive trees, organic fertilizer, chemical fertilizers, pesticides, and labor. The research was conducted in Senaning Village, Pemayung District and Pompa Air Village, Bajubang District. The selection of the study sites was purposive sampling and deliberately determined on the basis those villages were production areas of siam oranges in Batang Hari Regency. The functional form of production function was the Cobb-Douglas model and to see the level of efficiency of using production factors on siam oranges farming used allocative efficiency analysis. Based on the results of this study factors of organic fertilizers and labor significantly affect siam oranges production. Generally, siam oranges production was relatively responsive to the number of production factors used. The use of factors production i.e. productive trees, organic fertilizer, and chemical fertilizers were relatively efficient but the pesticide and labor variable was not. There were productivity differences between siam orange farming in Senaning Village and Pompa Air Village. Government and societies should concern a suitable agroecological and skilled farmers to develop a new area production of siam oranges in Batang Hari Regency.

Today, manufacturing companies, on a global level, are facing major changes that cause a complex form of successful business. Given the rapid growth of the IT information industry, high technology in complex industries, complex production processes, know – how and other innovations, increasing efficiency should be a strategic goal of all developed companies in the world. Basically, the business management of these industries is aimed at increasing efficiency by applying efficient methods and techniques that give good results in engineering. This primarily refers to those techniques that today in a complex time of business, can give a high quality approach to business management, highly efficient organization and high quality products and services that will conquer world markets today and in the future. The concept of TQM – total quality management throughout the company worldwide, originated from Japanese companies in the 1970's and quickly spread to all manufacturing companies in the world. On that basis, it can be said that the strategic intention, assessment and goal of the path of each management that will lead the business towards the fulfillment of market laws of business. One of the most important methods of the TQM concept is Business Process Reengineering, which brings fundamental business improvements to both the main and ancillary processes of industrial business.

Besides frontiers and Data Enveloped Analysis approaches, a combination between the aggregate production function and technical efficiency can be performed using the Corrected Ordinary Least Square approach. Unfortunately, there are no studies in Indonesia that use this approach. This paper mainly studies how the Corrected Ordinary Least Square approach combines aggregate production function and technical efficiency. The methods are aggregate production function modeling, aggregate production function correcting, and technical efficiency measuring. The data are Gross Regional Domestic Product at a constant price, the number of workers, investment expenditure, education, and health data of Indonesian provinces from 2015 to 2020. There are three results. First, the Indonesian fixed effect panel data aggregate production function is the best model. In this model, Gross Regional Domestic Product at a constant price is influenced by the number of workers, investment expenditure, and human capital. Human capital consists of education and health level. Second, the deterministic frontier aggregate production function shifts the best-fixed effect model so that the constant becomes –15.36. Third, the Indonesian technical efficiency when no factors influence inefficiency is on average 0.9936. All the results indicate that human capital, aggregate production and technical efficiency combination, and the Corrected Ordinary Least Square approach are practical values.

The changing food demands by the teeming urban population, job search, and sector profitability have made vegetable production indispensable as it contributes to increased incomes and livelihoods of urban dwellers.This study investigated the current level of productive efficiency (technical and allocative) of vegetable farmers in the Kumasi Metropolis using cross-sectional data obtained from 135 sampled farmers using a semi-structured questionnaire. Data analysis was conducted using the stochastic frontier approach to estimate firm-specific technical efficiencies and the factors that influence efficiency levels. The results show that inefficiency exists among the sampled vegetable farmers as they currently achieve an average technical efficiency score of 66.7%. Allocative efficiency estimates for land and labour revealed that both factors of production are over utilised by farmers. The age of the farmer is the main socio-economic determinant of technical efficiency.The study recommends that farmers be educated on the correct use of inputs by extension agents. The government policy of recruiting community extension agents under the ‘planting for food and jobs’ programme is in line with addressing inefficiency in the production sector and should be promoted.

Abstract: We use Stochastic Production Frontiers to estimate the recent levels and the evolution of productive efficiency across regions in Brazil. Results are available for agriculture, industry and services, as well as for total production. We observe a substantive efficiency growth exhibited by agriculture at the national level, which is counterbalanced by the poor performance of services. The regional results show that efficiency levels still replicate, in general, the regional inequality that marked the country’s history through decades. However, the efficiency growth reveals new signs of convergence among states, especially for industry, with effects on the aggregate production. This indicates that inequality trends in productive efficiency may be starting to change.

PurposeThe purpose of this paper is to analyze the productive efficiency and the best operational practices in an armaments manufacturer.Design/methodology/approachA longitudinal case study is performed using data envelopment analysis (DEA). Using DEA, an assessment of six years in the company manufacturing process is conducted. The research aims at developing an internal benchmark on three production lines of the company.FindingsThe results show that only one of the three analyzed production lines increased efficiency over time. With this result, the most efficient production line may be used as a reference in relation to the best operational practices of the company. Moreover, it was found that the current indicators to evaluate efficiency are insufficient and may lead to wrong management decisions.Practical implicationsThis research could allow a larger understanding of the factors that really contribute to increased operational efficiency. This is due to internal benchmark assist in the identification of the best practices. The identification of best practices can contribute to enhance the efficiency of inefficient operations without the need for external comparisons.Originality/valueDEA contributes due to its robustness, for the evaluation of productive efficiency. One of the contributions of this study is to identify opportunities for improvement in key components of the operation through targets, internal benchmarking and robust assessment of productive efficiency.

This paper Identifies factors that affect the productivity and economic efficiency of dairy breeders. The research problem is focused on low production efficiency (milk production in Egypt compared to other countries), which is reflected in the lower average consumption of Egyptian animal protein than the level of safety. The research aims to show milk producers' productivity and economic efficiency from its various sources in the Ibrahimi and Minya al-Qamh Centres in the Al-Sharkia governorate. The research used SPSS V. 20 in linear, logarithmic, and double images to reach the best images, the results of which are consistent with statistical and economic logic. The study proved that the most important factors affecting the production of cow's milk were the amount of concentrated feed and the amount of human action, while the factors affecting buffalo milk production were the amount of green and dry feed. We conclude from the indicators of economic efficiency that Minya al-Qamh is better than that of The Patriarchs (except buffalo in the first category and this is consistent with the results of the production functions because production is done in the non-economic phase).

The purpose of this study is to examine a productive efficiency index that incorporates two new production factors of sustainability—an environmental variable as an undesirable output and a well-being indicator as a desirable output—for 12 years of data from 2007 to 2018 pertaining to 47 prefectures in Japan. This study proposes a combination of a new data envelopment analysis (DEA) intermediate approach with the DEA super-efficiency model to measure the integrated productive efficiency. The approach incorporates CO2 emissions and a well-being indicator into the conventional productivity index. A three-stage analysis is conducted by sequentially adding new factors, CO2 emissions, and a well-being indicator. We also conduct a club convergence analysis of the productive efficiency and observe how clubs are formed, what their characteristics are, and how the efficiency changes over time. Through these approaches, we examine the practicality of the new efficiency measure and discuss regional policy implications. We found that higher labor productivity and carbon productivity in major industries caused increased productive efficiency. Adding sustainability factors to the conventional production factors in efficiency measurement widened the efficiency gap among prefectures.

To determine the key variables of the vineyard efficiency is imperative to account the combined effects of the inputs interactions since they have implications on the overall final production. This paper estimates the productive efficiency of a wine-farm sample from the Douro Demarcated Region (DDR) while identifies economic, social and environmental indicators that characterizes the DDR grape production system. The data was collected by face-to-face surveys performed at farm level to build a pilot study. The majority of the sampled twenty farms are dedicated to mountain viticulture and mainly feature the cordon (simple and double) training system. Through the Data Envelopment Analysis (DEA) method, the productive efficiency of the sampled was performed and the results clinched different efficiency scores. The main explanation is related to the heterogeneity of the adopted production system. In addition, they revealed how grape producers could improve their productive efficiency by adopting particular practices and identifying the key factors of their system.

Malgré son importance, la culture de l’anacarde se fait au Bénin sans application d’engrais avec des conséquences néfastes sur la durabilité des systèmes de production. La présente étude visait à évaluer les efficiences agronomique, de recouvrement et physiologique suite à l’application des différentes fumures sur les anacardiers de différents âges. A cet effet, des arbres de quatre et huit ans d’âge ont été fertilisés au cours de deux campagnes de production (2013-2014 et 2014-2015) dans les plantations paysannes de Glazoué au centre Bénin. Les types de fumure considérés étaient : témoin absolu sans application d’engrais, fumure minérale et fumure organo-minérale. L’efficience agronomique, l’efficience de recouvrement et l’efficience de l’utilisation du nutriment ont été les principaux paramètres testés. Les résultats ont montré que les efficiences agronomiques les plus élevées étaient obtenues au niveau des arbres ayant reçu la fumure organo-minérale (21,15 g/g ; 22,25 g/g ; 1,99 g/g ; 2,97 g/g). De même, les efficiences de recouvrement les plus élevées étaient obtenues au niveau des arbres ayant reçu la fumure organo-minérale (32,13% ; 28,25% ; 12,56% ; 17,75%. Par contre, la fumure minérale avait présenté les plus fortes valeurs d’efficience physiologique. Une gestion intégrée de la fertilité des sols permettra de compenser durablement les exportations de nutriments dans les noix et les pommes cajou. English title: Agronomic and nutritional efficiencies following the fertilizers application on cashew trees (Anacardium occidentale L.) in Benin Despite its importance, cashew is cultivated in Benin without fertilizers with consequence on the durability of production systems. The present study aimed to evaluate the agronomic, nutritional and physiological efficiencies following the fertilizers application on cashew according to tree age categories. Four and eight years old cashew tree from farmers plantation were fertilized during two growing seasons (2013-2014 et 2014-2015) in Glazoué (centre Benin). Fertilizer types considered were: control without fertilizer, mineral fertilizer and combined organic manure and mineral fertilizer. Agronomic efficiency, cover efficiency and nutrient use efficiency were the main parameters tested. The results showed that high agronomic efficiency values were obtained with the combined organic manure and mineral fertilizer (21.15g/g; 22.25g/g; 1.99g/g; 2.97 g/g). Also, the high recovery efficiency values were obtained with the combined organic manure and mineral fertilizer (32.13%; 28.25%; 12.56%; 17.75%). On the other hand, mineral fertilizer presented high values of physiological efficiency. Integrated soil fertility management could sustainably compensate for nutrient exports in nuts and cashew apples

This study investigates the determinants efficiency of manufacturing subsectors in the Zimbabwean economy. The study applied the panel data econometrics approach in the leading manufacturing subsectors from 1980-2005. The technical efficiency estimates using SFA shows that there are varying efficiencies across sub-sectors and through time. The log-likelihood test shows that there existed technical inefficiency in the production processes in the manufacturing sector. This shows that the industries could improve their productive capacities with the same amount of inputs. The study shows that in the Zimbabwean manufacturing industries between 1980 and 2005 industries with strong the human capital development and foreign direct investment flowsÂ had higher efficiency. The concentration of foreign owned firms in an industry and capital intensity had no effect on the efficiency of an industry.

Rootstocks play a vital role in regulating the environmental adaptability and controlling the growth and development of apple trees. M9T337, an excellent apple rootstock widely used in commercial orchards, could confer dwarf tree architectures, early fruiting and suitability for high-density planting. However, the rooting ability of M9T3337 is low when it is vegetatively propagated, and researchers have not yet established an efficient micropropagation system. The present study systematically evaluated the multiplication in adventitious shoots and the in vitro formation of adventitious roots to determine the effects of the culture media and plant growth regulators of M9T337 and a rapid micropropagation system was developed. For the shoot multiplication, the highest multiplication index of 3.93 was obtained on Murashige and Skoog (MS) media supplemented with 2.0 mg/L 6-BA, 0.1 mg/L NAA and 0.3 mg/L GA3 from 12 combinations of 6-BA and NAA. Stronger and taller adventitious shoots were grown on MS supplemented with 1.8 mg/L 6-BA and 0.5 mg/L NAA. The optimal media with 100% rooting was obtained using 1/2 MS supplemented with 0.3 mg/L IBA or MS supplemented with 0.6 mg/L IBA for the rooting induction, resulting in mean rooting numbers of 13.00 and 11.33, respectively. Additionally, the effect on rooting of adding 0.3 mg/L IBA or not on the 1/2 MS and MS media was compared; the results suggested that an appropriate IBA concentration was the key to successful rooting. The rooted plantlets were acclimatised in a shaded greenhouse with an 84% survival rate. The established micropropagation system could be used for the rapid propagation of M9T337 for commercial production.

The economic efficiency of several beef production systems on pasture was investigated under different marketing strategies. All calculations were carried out with the computer program ECOWEIGHT. None of the considered production systems was profitable without government subsidies for the assumed economic input values. The subsidies granted when satisfying a set of conditions served for balancing the economic loss in systems selling all surplus weaned calves outside. A profitability of 10 to 25% was reached for this marketing strategy in dependence on the production system. When integrating feedlot, only the purebred system with mating female replacement at an early age (about 15 months) and selling breeding bulls showed profitability, but at a low level (5%). All other systems produced at a loss even when government subsidies were included. A detailed analysis showed a high variability of the profit and profitability of cow-calf production systems in dependence on breeding and marketing strategies and on the level of the biological and economic input parameters. When considering biological performance, reproduction of females was shown to be the main source of economic efficiency in herds producing calves for sale. When applying feedlot, the daily gain in fattening was even more important. Beef prices seem to be the most important economic factor influencing the profitability of all systems (prices for slaughtered animals in the variant with integrated feedlot, prices for calves in the variant with selling of weaned surplus progeny).

Purpose The purpose of this paper is to explore Taiwan’s regional energy efficiency trend and complement the work of the total-factor energy efficiency (TFEE) index proposed by Hu and Wang (2006). It further extends panel data stochastic frontier analysis (SFA) modeling for estimating disaggregate energy efficiency. Design/methodology/approach This paper applies the panel data stochastic production frontier to estimate the TFEE scores for 20 administrative regions in Taiwan over the period 2004-2015. The SFA models include five inputs (employed population, amount of productive electricity power consumed, amount of electricity consumed for household and non-household electric lighting, amount of gasoline sales, and amount of diesel sales) and one output (total real income in the base year of 2011). Findings This research concludes with three main findings: the inefficient administrative regions of Taiwan include mostly large industrial parks and the petrochemical industry cluster; the top five administrative regions with inefficient diesel use are mostly metropolitan areas that the concern of air pollution caused by diesel system arouses the awareness to use less diesel fuel; and the average TFEE score on household and non-household electric lighting is higher than the usage efficiency of productive electricity power, gasoline, and diesel, but there is still room for efficiency improvement. Originality/value Most administrative regions in Taiwan are not efficient in almost all kinds of energy use. The results show that the efficiencies of using productive electricity power, gasoline, and diesel need to be improved a lot more.

The purpose of this research is to find out the Role of total productive maintenance application for increasing the efficiency of timber processing production. The method of research is using TPM and OEE. The highest OEE value on the Under Cut machine is 71.91%, Thicknesses = 76.93, Surface Planner = 75.06 %, Six Drill = 69.62 %, Double-end = 86.50 %, spindle Moulder 85.21%, single shaper 72.85%, and automatic Round Dowel machine = 80.63 %. If the eight machines have OEE, there are 2 machines that reach the optimum condition, namely OEE > 85 %. While others are under optimum conditions. The factors that contributed the most so that the ideal OEE value was not achieved during the period Mei-July 2020 and became the main priority for elimination by the company on the Under Cut machine were the Indling factor and Minor Stoppages Loss of 46.83%, reduced speed loss of 29.23% on the Thicknesser factor machine. The dominant ones are Idling and Minor Stoppages loss 44.63% reduced speed loss 17.12%, then meisn 40.11%, then Reduced Speed 71.72%.
