Seed production of farmers preferred improved maize varieties under community based seed production(CBSP) group initiated in the hills of Nepal under Hill Maize Research Project in 2000. Trained members of the community group produce improved seeds identified through participatory varietal selection procedures. Despite quantum jump in maize seed production, 14 tons by 7 CBSP groups in 2000 to 1,036 tons by 207 groups in 2012, seed marketing remained one of the challenges in HMRP districts. Main objective of this study was to analyze maize seed production trend and presowing seed contracts in hill districts under HMRP. Linear regression model showed seed production trend over the period 2000 to 2012 highly significant. Annual compounded growth rate of seed during the same period was estimated to be 34.36%. Pre-sowing seed contract in cereal crops in the hills of Nepal is a new initiative of HMRP IV. Analysis showed 63 formal contracts were signed for 170.45 tons of improved maize seed between 50 CBSP groups and 24 private seed buyers/traders.

A review on the community based maize seed production and technology dissemination in Nepal was made in 2009 to know the seed production situation and technology dissemination approaches. Twenty three open pollinated maize varieties and one hybrid were released by the Nepal Agricultural Research Council (NARC) up to 2009. A number of stakeholders were involved on improved technologies dissemination, seed production and marketing. Approaches for technology dissemination include district seed self sufficiency program (DISSPRO) and community based seed production (CBSP) program. About 4500 ton of cereal seeds annually has been producing from these approaches. Approach include subsidies on source seeds, creation of revolving funds, group/co-operative formation, their mobilization for participatory varietal selection (PVS), demonstrations, training, informal research and development (IRD) kit distribution and exchange visits. In community level, activities such as community based seed production approaches, particiapatory technology development, verification and dissemination for sustainable seed production and marketing has been taken place.

AbstractSoil microbe is crucial to a healthy soil, therefore its diversities and abundances under different conditions are still need fully understand.The aims of the study were to characterize the community structure and diversity of microbe in the rhizosphere soil after continuous maize seed production, and the relationship between the disease incidence of four diseases and the variation of the rhizosphere microbe. The results showed that different fungal and bacterial species were predominant in different cropping year, and long-term maize seed production had a huge impact on structure and diversity of soil microbial. Ascomycota and Mortierellomycota were the dominant fungal phyla and Mortierella and Ascomycetes represented for a large proportion of genus. A relative increase of Fusarium and Gibberella and a relative decrease of Mortierella, Chrysosporium, Podospora, and Chaetomium were observed with the increase of cropping year. Pathogenic Fusarium, Curvularia, Curvularia-lunata, Cladosporium, Gibberella-baccata, and Plectosphaerellaceae were over-presented and varied at different continuous cropping year, led to different maize disease incidence. Proteobacteria and Actinobacteria ranked in the top two of all bacterial phyla, and genus Pseudarthrobacter, Roseiflexus and RB41 dominated top 3. Haliangium and Streptomyces decreased with the continuous cropping year and mono-cropping of maize seed production increased disease incidence with the increase of cropping year, while the major disease was different. Continuous cropping of maize seed production induced the decrease of protective microbe and biocontrol genera, while pathogenic pathogen increased, and maize are in danger of pathogen invasion. Field management show great effects on soil microbial community.

The use of cytoplasmatic male-sterility in maize seed production contributes to increase economical efficiency and to obtain great genetical seeds. Through this theme one has followed the realization of a comparative study between some hybrids obtained to Turda on C and T cytoplasm their homologues, developed with normal and through the castration of the maternal parents. The researches aimed mainly the phenotypic and genotypic variability of the hybrids, the degree of male-sterility and the capacity of production, in phytotechnic conditions in different densities.

AbstractAuxinic herbicides, such as 2,4-D and dicamba, that act as plant growth regulators are commonly used for broadleaf weed control in cereal crops (e.g., wheat, barley), grasslands, and noncroplands. If applied at late growth stages, while cereals are developing reproductive parts, the herbicides can reduce seed production. We tested whether growth regulators have this same effect on the invasive annual grass Japanese brome. The herbicides 2,4-D, dicamba, and picloram were applied at typical field use rates to Japanese brome at various growth stages in a greenhouse. Picloram reduced seed production nearly 100% when applied at the internode elongation, boot, or heading stages of growth, whereas dicamba appeared to be slightly less effective and 2,4-D was much less effective. Our results indicate it may be possible to control Japanese brome by using growth regulator herbicides to reduce its seed production, thereby depleting its short-lived seed bank.

Deficits in reward decision-making are thought to contribute to criminal offending. These impairments have been measured in laboratory studies using the Iowa Gambling Task (IGT) which assesses implicit learning of different reward/punishment contingencies. This study compared IGT performance between a sample of justice-involved individuals and community-based individuals without an offending history. Participants included 100 adults from two Canadian federal correctional institutions (34% female, Mage = 39.14 ± 9.74) and a comparison group of 89 community adults with no history of offending (39% female, Mage = 37.04 ± 10.79). Responses on the IGT were analyzed for overall net score, learning across the task, and deck switching patterns. Associations between IGT performance and sentence characteristics and static factors assessment of recidivism risk were examined for the justice-involved group. The justice-involved group performed significantly worse than community adults in terms of net score. While the community group learned the advantageous strategy across the task, justice-involved participants exhibited minimal learning. This effect was moderated by recidivism risk within the justice-involved group, with individuals at low risk, but not medium/high risk, showing improvement over the blocks of the task. Finally, the justice-involved group also made greater use of an ineffective “win-stay/lose-shift” strategy. These results suggest that, compared with community participants without history of offending, incarcerated adults tend to employ maladaptive decision-making strategies that yield worse overall outcomes and the extent of impairment is associated with recidivism risk.

Abstract Black/African American adolescents from limited-resource communities face challenges and circumstances that are unique to their racialization and socioeconomic status; this merits community-engaged resources, such as community music therapy, that are equally unique in creating culturally responsive opportunities for limited-resource adolescents to engage socially with peers and experience meaningful success in a safe, supportive environment. The purpose of this study was to pilot and explore the feasibility of and behavioral processes in a community-based referential music-making intervention for limited-resource adolescents labeled as “at-risk.” The methods consisted of a concurrent nested (embedded) mixed methods design based on the principles of participatory actions research (PAR), during which qualitative data were collected during 8 focus group style music-making sessions. Quantitative data assessing self-efficacy were collected prior to first and following the 8th music-making session. The validity of quantitative results was challenged by the lowered reading level of participants and a high amount of mis-labeled (and thus unusable) data. Qualitative data suggest 3 themes, including creating community, artistic prioritization, and pride. All results were impacted by issues, such as inconsistent attendance and malfunctioning recording equipment. Nevertheless, participants expressed a collective desire to share their work with their community group. Discussion points are raised including how participants in this community music therapy-based approach were able to create and direct their own stories. The implementation of community music therapy approaches seems a valuable way to bring authentic representations of limited-resource adolescent participants into clinical practice.

For the factories it is essential, that the equipment and machines were available for the production process continuously. This is why we have to deal with the maintenance of the engines including diagnostics of machines and their main units. This analysis is dealing with the vibration diagnostics of conveyor’s rolling bearings. The test measurements were taken at a maize seed production factory. After analyzing the technology of the factory we have assigned which conveyors are the most important in the process of production. The measurements were taken. Based on the results of the analysis we have suggested the implementing of the vibration diagnostics.
