10. Yuta Sonoda, Kazato Oishi, Yosuke Chomei, Hiroyuki Hirooka, How do human values influence the beef preferences of consumer segments regarding animal welfare and environmentally friendly production?, Meat Science, 10.1016/j.meatsci.2018.07.030, 146, 75-86, 2018.12, [URL], Animal welfare and environmental impacts have been emphasized in the sustainable production of livestock. Labels are useful tools for clearly providing such attribute information to consumers. The aim of this study was to evaluate how human values influence consumer segments for beef with information on animal welfare and environmentally friendly production. Using a choice experiment, we examined whether animal welfare and environmentally friendly labels, country of origin and price impact consumer choice. As results, five heterogeneous consumer classes were identified using a latent class model: label conscious, domestic beef preferring, price conscious, animal welfare preferring and not interested in production method. Almost 90% of consumers were interested in and willing to pay for beef with animal welfare or environmentally friendly label. The classes with significant preferences for such labeled beef were affected by “openness to change” “self-enhancement” and “security”. Improving consumer attitudes and strengthening consumer perception towards labeled beef by marketers and policy makers will be required..

12. Dongpo Li, Teruaki Nanseki, Yosuke Chomei, Shuichi Yokota, Production efficiency and effect of water management on rice yield in Japan
two-stage DEA model on 110 paddy fields of a large-scale farm, Paddy and Water Environment, 10.1007/s10333-018-0652-0, 16, 4, 643-654, 2018.10, [URL], Abstract: Water management is increasingly important for rice productivity to maintain soil temperature and fertility with the presence of global warming. Meanwhile, rice production in Japan is in urgent need to reduce the costs through improving the efficiency and market competitiveness. This paper aims to measure effect of water depth and water temperature on rice yield of individual paddy fields and improve the practice of water management for them. In the first stage, we measure the production efficiency of rice yield through the adoption of data envelopment analysis. The results indicate that enlarged scale of the paddy fields increases the efficiency, and rice quality can be improved more than quantity. Moreover, the most inefficiently used inputs include the amount of fertilizer nitrogen and the soil capacity, which is a compound measurement of 21 soil chemical properties. In the second stage, after comparing the 20 paddy fields with highest and lowest technical efficiency, an observation shows that the rice yield is much more affected by water temperature than by water depth. The data of all the variables used in this study were sampled in 2015 and comprised of 110 paddy fields of Koshihikari, one of the most popular Japanese rice varieties, from a large-scale farm located in Kanto Region of Japan. In the analysis, the outputs include yields of raw paddy, paddy with 15% moisture, unsorted brown rice, sorted brown rice, milled grain rice, and perfect grain rice. The inputs include the field area, air temperature, solar radiation, fertilizer nitrogen, soil capacity, and farming conditions. Graphical Abstract: [Figure not available: see fulltext.]..

IOP Conference Series: Earth and Environmental Science
, 10.1088/1755-1315/185/1/012026, 185, 1, 2018.08, [URL], Japan is in urgent need to reduce the production costs through increasing rice yield, which depends highly on soil fertility. This study aimed to investigate determinants of rice yield, from the perspectives of fertilizer nitrogen and soil chemical properties. The data were sampled in 2014 and 2015, from 116 paddy fields, on a large-scale farm located in the Kinki Region of Japan. The rice included Koshihikari and other seven varieties, cultivated in conventional, special and organic regimes. The nine soil chemical properties included pH, cation exchange capacity, ammonium nitrogen, effective phosphoric and silicic acid, saturation of base elements, exchangeable potassium, lime and magnesia. Multiple regression analysis indicated that positive effects were identified for silicic acid, exchangeable potassium, and ammonium nitrogen; while phosphoric acid affects the yield negatively, controlling the rice variety, cultivation regime, and field area. Finally, countermeasures were put forward to improve soil fertility and rice yield..

22. 田中 一弘, Teruaki Nanseki, Yosuke Chomei, 仮想カタログ法によるIT生産管理サービスの評価―稲作経営体における収穫・水管理・施肥を対象として―, 農業情報研究, 10.3173/air.27.39, 27, 2, 39-52, 2018.06, [URL], We used a virtual catalog-based questionnaire to evaluate the attitude of rice farm managers to an information technology (IT)-based production management service. With the data, we assessed the likelihood of adoption of IT-controlled combine harvesters, paddy field sensors, automatic water supply systems, and fertilizer pouring machine on rice farms, by using cross-tabulation analysis, the Mann–Whitney U-test, and McNemar's test. More than 60% of farm managers showed an interest in or an intention to test these technologies; this result suggests a strong need among farm managers to improve yields. We identified a difference between farm managers and extension organizations in the desire to identify low-yielding paddies and the need for advice on increasing yields. Extension organizations were more likely to stay at the interest stage without recommending trials to test the merits of reducing the frequency of paddy visits to assess water management. To build a model for the diffusion of IT production management services, it is important for extension organizations to recognize the characteristics of farmer and managers..

29. Thi Hai Yen Dang, Teruaki Nanseki, Yosuke Chomei, The impact of microfinance on household welfare in rural Vietnam
A case study in Phu Tho province, Journal of the Faculty of Agriculture, Kyushu University, 63, 1, 185-189, 2018.02, In Vietnam, microfinance is regarded as one of the important measures to reduce poverty. However, empirical findings indicated that microfinance services can only meet less than half of the poor's demand. About 3.6 poor and near poor households remained vulnerable to external shocks in 2012. Therefore, this study aims to examine whether and to what extent microfinance programs have helped to increase household economic welfare in rural Vietnam. A survey was conducted in Phu Tho province - one of the poorest areas in the northern of Vietnam through face-to-face structured interviews with 257 respondents. The study employs a two stage least square regression model to deal with self-selection bias in the evaluation of the impact of microfinance on household welfare. The main outcome indicates that formal microfinance has helped to increase the household economic welfare in terms of per capita income, expenditure and value of non-land asset of the household with the coefficients are 0.002, 0.004, 0.003, respectively. Although the effect is small, microfinance has helped the better-off groups to increase their income and expenditure, while the poor groups increase their expenditure and acquire more assets, implying that the credit is distributed to other purpose besides income generating. However, these small impacts suggest a further study about the cost-effective of the microfinance programs..

Growth curve models and growth curve parameters were compared and analyzed for different genotypes and litter types. A total of 20,393 weight-age data from 208 female goats belonging to various crossbreeding genotypes were individually fitted to four growth curve models (Brody, Bertalanffy, Gompertz and Logistic). The goodness of fit was highest in the Brody model in most cases. A comparison of R2 among genotypes showed that they were highest for KK. There were no significant differences of genotypes for estimated mature weight in the Brody model. The estimated mature weights for KK were significantly lower (P < 0.05) than for GF × KK (F1), backcrosses with 75% GF genes (BC) and F1 × F1 (F2) in the other models. The correlations between estimated mature weights and the maturing rates were lowest for BC. The genotype significantly (P < 0.01) affected the age at the constant degree of maturity (67% and 90% of mature weight) in all models. The BC genotype was the youngest at maturity and KK the oldest. All models well expressed the growth pattern of the target animals when they were older than 2.5 years of age. The results from the present study showed that the growth pattern may be altered by crossbreeding of KK with the GF breed..
