Despite of this, the current productivity of the crop is below the potential. Low level of use of improved potato technology package is among the causes for low productivity. In this context, this study analysed the factors influencing adoption of potato technology package by smallholder farmers in Gurawa, Haramaya, Kombolcha, Meta, and Habro districts of Eastern Ethiopia. The analysis was based on a household survey conducted on 214 randomly selected potato growing households. A two-limit Tobit model was used to analyse the factors affecting adoption which is measured in an index computed from five components of the technology package. Variation in districts, access to irrigation, farm size, membership to cooperatives, and annual income of the households were found to significantly affect the adoption of potato technology package. Policy makers, planners and development practitioners are required to give due attention to these determinants in order to support smallholder farmers in production and productivity improvements from potato production.","PeriodicalId":320413,"journal":{"name":"Review of Agricultural and Applied Economics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130367091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The empirical results show a positive relationship between the adoption of improved maize variety and technical efficiency or productivity of farmers in the Semi-deciduous forest and Guinea Savannah zones. Generally, adopters of improved maize variety are about 6% to 8% more efficient than non-adopters. The estimated percentage increase in productivity due to the adoption of improved maize variety is about 53%. In the Semi-deciduous forest agroecological zone, adopters of improved maize variety are about 25% to 36% more efficient than non-adopters whilst in the Guinea Savannah agroecological zone, adopters of improved maize variety are about 15% to 26% more efficient than non-adopters. The estimated percentage increase in productivity due to adoption of the improved maize variety is about 8% in the Semi-deciduous forest zone and about 11% in the Guinea Savannah zone. The impact of adoption on technical efficiency in the Transitional zone is however negative. Adopters of improved maize variety are 7% to 8% less efficient than non-adopters and the estimated percentage decrease in productivity due to adoption of the improved maize variety is about 15%. Food safety net policies should pay attention to increased development and dissemination of improved crop varieties suitable to different agroecological zones.","PeriodicalId":320413,"journal":{"name":"Review of Agricultural and Applied Economics","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126809190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

QPM is an improved maize variety developed to reduce protein deficiency problems. A total of 100 maize farmers were sampled through a two-stage sampling procedure. Stochastic frontier approach using maximum likelihood estimation (MLE) was used to analyse the TE in the production of QPM, while probit regression was used to determine the effect of TE and other socioeconomic characteristics of the respondents on the adoption of QPM. The results revealed a mean TE of 0.89 and 0.78 for adopters and non-adopters of QPM respectively. This implied that adopters of QPM are more technically efficient than the non-adopters. Quantity of seed planted and fertilizer directly and significantly affected the TE of QPM while gross margin of maize farmers and income from other sources (at P<0.05), the level of education of farmers and QPM farm size (P<0.01) have significant and a negative effects on technical inefficiency from the results of the Tobit regression. The age (P<0.05) of the farmer has direct effect on technical inefficiency. In conclusion, TE, level of output, information availability on QPM and early maturity were significant determinants of QPM rather than the gross margin of production. Farmers decide to adopt QPM technology because of the high level of technical efficiency in the production of this variety. Their output from QPM can be increased by 11 percent, while the non-adopters can increase their maize output by 22 percent using the available technology.","PeriodicalId":320413,"journal":{"name":"Review of Agricultural and Applied Economics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126198864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data used were drawn from FAOSTAT, the National Centre for Atmospheric Research and World Bank Indicators respectively for the period 1961-2009. The data were separated into three sub periods, namely: entire period (1961-2009), the pre-Structural Adjustment Period (SAP) reform period (1961-1985) and the post SAP reform period (1986-2009). This was necessitated by the need to examine whether production systems may have been shifted out of the overall trajectory of system evolution by shocks e.g. policy (SAP) among others. To investigate whether there has been a degradation of the quality of the natural resource base across the diverse agro-ecological zones; the estimated TFP trends were related to changes in selected resource quality variables over time. The results showed that the Northern and Southern agro-ecological zones had non-negative trends in TFP, indicating sustainability of production systems. However, the result indicated that the policy instrument (structural adjustment programme) may have shifted farming or production systems out of the overall trajectory of system evolution in three out of the five agro-ecological zones studied which showed negative TFP trends. A degradation of resource quality over time was noted during the pre-SAP reform period, but was maintained during the post-SAP period.","PeriodicalId":320413,"journal":{"name":"Review of Agricultural and Applied Economics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122312210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multi-stage random sampling technique was adopted to select 96 beneficiaries and structured questionnaires as well as personal interview were used to collect data. Probit and logit models were used to analyse the factors influencing credit delinquency among food crop farmers in the state. Result of the descriptive analysis of the socio-economic characteristic of respondents revealed that 93% of male and 72% of female food crop farmers had one form of formal education ranging from primary to tertiary education. Empirical result from the Probit and logit models were similar and showed that borrower’s non-farm income, credit amount received, household size, net farm profit and farm size are determinants of credit delinquencies among food crop farmers in Akwa Ibom state. The study also discovered that the probability of food crop farmers being credit delinquent is about 0.427 ceteris paribus. It is recommended that food crop farmers should form marketing co-operative societies as a means of generating additional income to augment loan obtained. Furthermore, local government authorities should set up credit programmes that should focus on soft loans to rural farmers at a subsidize interest rate.","PeriodicalId":320413,"journal":{"name":"Review of Agricultural and Applied Economics","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133207874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Employee satisfaction has a significant impact on the economic and social sustainability of horticultural companies. Traditional linear relationships between environmental characteristics and subjective job satisfaction have been assumed in psychological research. Warr (2007) challenged this conception with the non-linear vitamin model. The present study examines the possibility of non-linear relationships between job characteristics and job satisfaction. For this purpose, a survey was carried out using an online and a paper-and-pencil questionnaire from August 2013 to February 2015. In addition, the preferences of employees (N=229), vocational and master craftsman scholars (N=205) and students of horticulture science (N=204) regarding job characteristics were examined. This article focuses on the later two. The relationships between characteristic values and work and life satisfaction are analysed and the results of the three groups are compared. The strongest relationships with job satisfaction can be observed for vocational and master craftsman scholars for the job features emotional dissonance and considerate leadership. Additionally, employers' fair treatment of the society as a whole has a strong impact on job satisfaction. The salary can be found only in the lower middle range. The data support the assumption of non-linear relationships between job characteristic values and satisfaction. Furthermore, the personal characteristics of the study participants are included in the analysis. The study indicates a change in the preference structure of employees, who in the future would prefer a good work–life balance in particular as well as other \"soft\" factors.","PeriodicalId":320413,"journal":{"name":"Review of Agricultural and Applied Economics","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116814575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
