Enhancing Production

This paper examines the productivity of hired and family labour and determinants of technical inefficiency of fish farms in Ghana. A modified Cobb-Douglas stochastic frontier production function which accounts for zero usage of family and hired labour is employed on cross-sectional data of 150 farmers collected in 2007. The results reveal that family labour, hired labour, feed, seed, land, other costs and extension visit have a reasserting influence on fish farm production. Findings also show that family and hired labour used for fish farming production in Ghana may be equally productive. The combined effects of operational and farm specific factors (age, experience, land, gender, pond type and education) influence technical inefficiency although individual effects of some variables may not be significant. Mean technical efficiency is estimated to be 79 percent. Given the present state of technology and input level, the possibility of enhancing production can be achieved by reducing technical inefficiency by 21 percent through adoption of practices of the best fish farm.

Frontier Production Function

The inverse relationship between farm size and productivity is one of the most debated findings in agricultural productivity researches of developing countries. Aquaculture industries of Bangladesh have been expanded tremendously but most of the aquaculture farms are small and their productivity is not as high as expected. This paper has explored the relationships among farm size, productivity and efficiency of pangas fish farms. A survey was conducted on 125 farmers by direct interviewing in Mymensingh district of Bangladesh.  Stochastic frontier production function was carried out to estimates the level of technical efficiency and polynomial regression was employed to show the relationship among farm size productivity and efficiency in pangas fish farming. In general, pangas fish farming was found to be profitable, where the large size farms were more profitable than the small. Feed and salt had highly significant and positive effects on productivity, while human labor had negative influences. Larger farms were found to be more productive and technically efficient than the smaller one, and the more productive farms were found to be more efficient. These findings could be justifiable by the fact that the large size farms enjoy more financial opportunities, management and marketing facilities in commercial mode and all these facilities help them to enhance productivity and efficiency.

Objective of research: to perform the parasitological monitoring we have to study the parasite fauna in fishes from different fish farm factories, calculate the index of similarity, estimate the influence of abiotic and biotic factors on the ecosystem of fish-breeding reservoirs. Materials and methods: parasitological monitoring of factory fish farms was conducted by the method of complete and incomplete parasitological examination taking into account the data obtained from various fish-breeding reservoirs. Results and discussion: the parasite fauna of cyprinid fishes is represented by 56 species, carriage of causative agents of parasitic diseases in fishes is detected. Index of similarity of parasite fauna in carps has been studied and typification of agricultural reservoirs carried out. Index of similarity between the parasite fauna in carp and herbivorous fish was 22–33 %, carp and rough fish - 18–30,7 %. Influence of abiotic (oxidability, reduction of oxygen and nitrogen ammonia concentration, mineralization) and biotic – anthropogenic factors (violation of processing technologies, veterinary and sanitary rules of fish transport and fish farming operations) on fish infestation with parasites was studied. The role of parasitological monitoring in prevention and elimination of fish diseases was shown.

Frontier Production Function

This study aimed to estimate the stochastic frontier production function and the inefficiency function and technical efficiency of potato production by using cross-section data collected from 173 potato farms that were randomly selected in Baghdad province/ Yusifiyah for production season 2016. The results showed that 90.6% of inefficiency in production was due to technical inefficiency. Also, there was a significant relationship between the variables of inefficiency function and the inefficiency of farms. The values of the parameters of the stochastic frontier production function were positive and significant for both human work hours and the amount of seeds. However, the parameter of DAP fertilizer was negative and significant. The estimation of the technical inefficiency function showed that its parameters were significant for both the local seed provider and the agricultural season (fall), while the parameters experience in growing potatoes and the number of irrigations were significant and their impact was negative on the inefficiency. The results also showed that the technical efficiency of the study sample (50%) on average. The researchers recommended the necessity of providing imported seed tubers for the increased productivity in dunum to achieve technical efficiency.

Two models of technical inefficiency with a stochastic production frontier are considered in this paper. In the frrst model, it is assumed that the frontier itself does not vary with time, while in the second, the frontier is allowed to move. These models are applied to four years of panel data on wheat farmers in four districts of Pakistan: Faisalabad and Attock in the Punjab, Badin in Sindh, and Dir in the NWFP. Using essentially the same stochastic frontier production function in each of the four districts involved, different stochastic specifications for the inefficiency effects are obtained for the different districts. Technical efficiencies of production of the individual farmers are predicted in each year in which they are observed. Varying patterns of technical inefficiency are observed. The null hypothesis (of no technical inefficiency) cannot be rejected in only one district. In the other districts, while inefficiencies appear to be present in all of them, they are declining at a fairly rapid pace in one. The results highlight the importance of analysis at a disaggregated level because it is clear that both the rate of technical change and relative efficiencies vary across regions and explicit cognisance must be taken of this both in research and policy formulation.

A Norwegian Standard NS 9415 (NAS, 2003) has been introduced to the offshore fish farming industry in Norway. This is the first standard dealing with offshore fish farm facilities. The main objective of the standard is to reduce environmental pollution by fish escape. The work process leading to NS 9415 revealed the need for research work in several areas to enhance design criteria with the objective of having a consistent safety level through out the life cycle of a fish farm facility. This paper presents results from a government supported research project with the objective of enhancing criteria for design and operation of fish farm facilities. A case study of a fish farm facility representative for the majority of polyethylene based fish farms in Norway is presented and the sensitivity of such fish farms to variation in the mooring system is shown and discussed for design relevance. The sensitivity of net cage volume to current and weights is presented and discussed. Possible hazards from operational conditions are listed.

Implementation of Integrated Crop Management (ICM) on maize farming in dry land is expected to increase the production and efficiency. This study aimed to: 1) analyze technical, allocative, and economic efficiencies of dry land maize farming under ICM and non-ICM implementation program, 2) identify factors that influence the technical inefficiency of maize farming under ICM and non-ICM implementation program. The study was conducted in maize production center in West Java province at Sukabumi and Garut regencies. Stratified random sampling method was used to survey 300 households in 2015. The data were analyzed using the Cobb-Douglas stochastic frontier production function; while allocative and economic efficiencies were analyzed using the input side approach with frontier dual cost function. The results showed that the productivity of ICM maize farming was 18% higher than the non-ICM. The level of technical, allocative and economic efficiencies of ICM maize farming were 88%, 22%, and 20% respectively, while the level of technical, allocative and economic efficiencies of non-ICM maize farming were 78%, 18%, and 14%, respectively. The level of technical, allocative and economic efficiencies increased by 11% to 30% higher in ICM than the non-ICM. Factors causing technical inefficiency were frequency of extension, educational level, and distance of farmland from farmers residence.

Frontier Production Function

<p><strong>English</strong><br />Technical efficiency and profitability are the key for business enterprise development. Kupang regency is a center of smallholder broiler farms in East Nusa Tenggara Province that evolve with partnership and non-partnership types of enterprises. The study aims to analyze technical efficiency and profitability of the two types enterprises that may be useful in formulating broiler farming development in policy in Kupang Regency. Data was collected from purposively selected of 30 partnership farmers and 30 non partnership farmers in July 2019-August 2020. Technical efficiency was measured using the stochastic frontier production function. Profitability was measured using the R/C ratio. Results showed that both partnership and non-partnership enterprises are technically efficient, but technical efficiency of the non-partnership group is higher than the partnership group. Determinants of technical inefficiency of the partnership group are farmers’ education and family size. Determinants of technical inefficiency of the non-partnership group are farmers’ education, length of farming experience and family size. The non-partnership enterprises are more profitable than the partnership enterprises with average R/C ratio 1.19 and 1.06, respectively. Appropriate use of inputs, technology innovation and good farm management practices should be facilitated by the government in order to further increase farm technical efficiency and profitability.</p><p><br /><em></em></p><p><strong>Indonesian</strong><br />Efisiensi teknis dan profitabilitas adalah kunci utama perkembangan suatu usaha. Kabupaten Kupang merupakan salah satu daerah sentra peternakan rakyat ayam broiler di Provinsi Nusa Tenggara Timur, yang sedang berkembang dengan pola usaha sistem mitra dan nonmitra. Penelitian bertujuan untuk menganalisis efisiensi teknis dan profitabilitas kedua pola usaha ternak ayam broiler yang diharapkan berguna dalam perumusan kebijakan pengembangan peternakan ayam broiler di Kabupaten Kupang. Data dikumpulkan dari 30 peternak mitra dan 30 peternak nonmitra yang dipilih secara purposif pada Juli 2019–Agustus 2020.  Efisiensi teknis diukur dengan mempergunakan fungsi produksi <em>stochastic frontier.  </em>Profitabilitas diukur dengan R/C rasio. Penelitian menunjukan bahwa peternakan ayam broiler pola kemitraan maupun nonmitra adalah efisien secara teknis namun efisiensi teknis kelompok nonkemitraan lebih tinggi dari kelompok kemitraan. Inefisiensi teknis usaha ternak mitra dipengaruhi oleh tingkat pendidikan peternak dan jumlah tanggungan keluarga. Sedangkan inefisiensi teknis usaha ternak nonmitra dipengaruhi oleh tingkat pendidikan peternak, pengalaman beternak, dan jumlah tanggungan keluarga. Usaha ternak nonmitra lebih menguntungkan dibandingkan sistem mitra dengan nilai R/C rasio berturut-turut 1,19 dan 1,06. Penggunaan <em>input</em> yang sesuai, inovasi teknologi dan penerapan manajemen usaha ternak yang baik perlu difasilitasi pemerintah guna meningkatkan efisiensi teknis usaha dan profitabilitas usaha ternak.</p>
