In this paper, we propose a new method for time series prediction which is based on the concept of time series motifs. Time series motif is a previously unknown pattern appearing frequently in a time series. In the proposed approach, we first search for time series motif by using EP-C algorithm and then exploit motif information for forecasting in combination of a neural network model. Experimental results demonstrate our proposed method performs better than artificial neural network (ANN) in terms of prediction accuracy and time efficiency. Besides, our proposed method is more robust to noise than ANN.

A set of 12 stable crop wild relative (CWR)‐derived rice lines with introgressions from wild rice Oryza rufipogon Griffiths and O. nivara S.D. Sharma & Shastry was evaluated for their phenotypic response to salinity tolerance by a participatory selection approach on farm in the Phuoc Long and Gia Rai districts, Bac Lieu province. The evaluation of the results showed that four lines derived from CWR are well adapted to the local environmental conditions, with high grain yield (>6.5 t ha−1), early maturity, and short plant height. These CWR‐derived lines were adopted by farmers and proposed for testing on a larger scale in different areas of the coastal zone.

A collection of 200 crop wild relative (CWR)‐derived BC3F3‐4 rice (Oryza sativa L.) lines developed at the International Rice Research Institute (IRRI) were evaluated by farmers in the Mekong Delta over two seasons for agronomic performance. Fifty stable BC3F5 lines were selected and subsequently screened in hydroponics using three NaCl concentrations to assess their phenotypic response to salt stress. The lines and check varieties were grown in a salinized Yoshida nutrient solution at three concentrations: 68, 102, and 13 mM NaCl. Several lines were identified to be tolerant to salinity stress and ANOVA showed significant differences among genotypes and NaCl concentrations. Root and shoot growth parameters showed an inverse relationship with increasing NaCl concentration. Population genetic analysis suggested four groups of genotypes, where the median salt injury score across the three NaCl concentrations was identified as the main clustering factor. Lines from Cluster 3 were identified as the most promising donors of salt tolerance.

Most of existing systems use only one approach to make recommendation for all employees, while a specific method normally is good enough for a group of employees. Therefore, this study proposes an adaptive solution to make job recommendation for different groups of user. The proposed methods are based on employee clustering. Firstly, we group employees into different clusters. Then, we select a suitable method for each user cluster based on empirical evaluation. The proposed methods include CB-Plus, CF-jFilter and HyR-jFilter have applied for different three clusters. Empirical results show that our proposed methods is outperformed than traditional methods.

These changes have been documented through their on-farm research and intervention activities for 11 crops in Phu Thuong Co-op, Phu Tan district of An Giang province and Kenh 7b Co-op, Tan Hiep district of Kien Giang province. With the Participatory Technical Development approach, the VLCRP’s low carbon rice farming protocol namely 1Must 6 Reductions (1M6R) has been piloted, and more than 500 farmer households have been trained to cultivate rice on an area of 540 hectares, for 3 crops per year. Over the two communities were VLCRP has worked, rice farmers that have adopted 1M6R have reduced their seed density by 50%, fertilizer by 30-40%, water irrigation by 40-50%, pesticide by 30%, and labor costs by 20% while increasing their yield from 5-10% resulting in an increase their net profit...

Household interviews were conducted with the male head as well as spouses of each selected farm families that take part in Sustainable Rice Platform (SRP) training course. The total sample size of the study was 150 respondents (including 75 male and 75 female respondents). A designed structured questionnaire was prepared for the data collection as the research instrument with the three-point and fivepoint Likert scale. The data thus collected were coded on SPSS for analysis and interpretation. Results of the study showed that there was a significant difference in age and educational status of male heads and their spouses. The farming sources are the primary income sources in all households. The intensity of participation of male respondents in different crops, and livestock activities was comparatively high as compared to their female counterparts. Their participation in crops and livestock activities showed that male-headed households had access to agricultural extension services and SRP training course as the same as women' participation. Especially, there are four common factors affecting women's participating decision in SRP training course including: spending too much time on house matters, spending less time on participating social activities, lacking experience regarding production, and depending too much on the decision made by their husbands.

Such evaluation of crop plant genomic structures may reveal useful resources and/or unique characteristics hidden in local collections (Hermisson and Wagner, 2004;
