A series of seed-processing machines were used to evaluate seed quality improvement in paddy during the Kharif season 2013-14. The processing machines proved an efficient tool in producing quality seeds. The consistent and higher seed quality (germination 91.67% and physical purity 99.83%) could be achieved by efficient use of processing machines. The product and separate (reject) from individual machines were analysed to evaluate machine efficiency in separating the seed components as well as impurities from the harvested lot. The air-screen machines were found effective in removing dead seeds, whereas specific gravity separator removed abnormal seeds significantly. Gradual increase in seed quality was recorded with decrease in recovery in the processing line. Seed loss in reject port was always associated with handling of seed lots by each machine and observed only 1.30%. Specific gravity separator was found essential for the seed lot of medium-term storage or for the buffer stocking.

Purpose Increasingly, the content that libraries collect is no longer on paper, a long-lived, medium whose technology changes very slowly and with which they have centuries of experience. Instead, it is stored on relatively short-lived digital media whose technology appears to change rapidly and with which they have little history. The paper aims to discuss this issue. Design/methodology/approach The storage media industry is highly competitive and is currently evolving rapidly as flash, a solid state medium, displaces spinning disk from many applications. Long-term archival storage is a small part of the total storage market. It typically re-uses media and systems intended for more general bulk storage. Findings What are the medium-term prospects for change in this market? Originality/value Much of this material has appeared in blog posts and talks aimed at storage experts, such as the recent DARPA workshop on future of storage. It is presented here for a librarian audience with the necessary additional exposition and background.

When harvesting cabbage by machine, the heads of cabbage are severely injured. Mechanically damaged heads of cabbage are poorly stored. Therefore, the machine technology of cabbage harvesting should provide protection of heads of cabbage from mechanical damage. The purpose of the research is to study the qualitative indicators of the operation of a multivariate cabbage harvester with various harvesting technological schemes. The considered technological schemes for harvesting cabbage include: careful shipment of heads in bulk of a universal vehicle (Scheme 1); careful point shipment of heads of cabbage into containers installed in the back of a vehicle (diagram 2); shipment of heads of cabbage on a flexible flooring installed in the vehicle, with their subsequent careful transfer to containers manually (Scheme 3); stowing heads of cabbage into containers on an accompanying trailer manually (Scheme 4). During the production check, under conditions typical for the main regions of mass marketable production of cabbage, the multivariate cabbage harvester steadily performed the technological process. At the same time, its quality indicators met the established agrotechnical requirements. Combine operation according to schemes 3 and 4 ensured the preservation of product quality to the maximum extent: damage to heads of cabbage did not exceed 5 ... 6%, the completeness of cabbage leaves removal was 95 ... 100%. Therefore, its use according to schemes 1 and 2 is recommended mainly when harvesting cabbage for short-term and medium-term storage, according to schemes 3 and 4 - when harvesting heads of cabbage intended for long-term storage

AbstractSalix xerophila, S. maximowiczii, and S. koreensis are species of willow native to Korea that are important for bioenergy production. However, the native range of these species has narrowed in recent years due to the impact of climate change. Seeds of these Salix species lose viability within 4 weeks at ambient temperature, and within 4 months at -4°C. Preservation techniques are urgently needed to protect these valuable resources. The effects of seed water content (SWC; 3%, 6%, 9%, 12%, 18%, and 24%) and temperature (ambient, 4°C, -18°C, -80°C, and -196°C) on storage stability were investigated for up to 48, 52, or 60 months, depending on species. Optimal storage temperature and SWC varied between species. S. xerophila seed could be stored without deterioration for 60 months with 9% SWC at -80°C, but rapidly lost viability when stored at -18°C. In S. maximowiczii and S. koreensis, 100% and 90% of normal germination, respectively, was maintained with 18% SWC at -18°C or -80°C. Thus, for some Salix species, storage at -18 and -80°C may provide an economical alternative to cryopreservation or medium-term storage for the maintenance of seedbanks or breeding stocks.

Fresh horticultural goods often require drying post-harvest to preserve quality and allow for successful long-term storage of plant material. Given the influx of hops cultivation in the state of Florida, this 5-page publication will help Florida hops growers and hobby brewers to understand how to efficiently dry hops prior to storage.
