  1. The estimation of the health status of plants and fruit by fluorescence approaches: a short review

    Valcke, Roland
    The use of non-invasive optical techniques to assess the health status of plant material, such as crops in agriculture and horticulture, has been improved much during the last decades. One can use laboratory designed instruments and or transportable-portable field equipment. The first group includes for instance spectrophotometric techniques such as absorption (UV-VIS), fluorescence and infrared spectroscopy and chlorophyll fluorescence methods. Each technique has its specific characteristics and will deliver specific information on the material examined. Field designed instruments are mostly less complicated and should be portable or at least transportable and battery operated. In this group, several techniques based on...

  2. Systems Integration for Biochar in European Forestry: Drivers and Strategies

    Sohi, Saran; Kuppens, Tom
    Biochar is a product with multiple functions and a range of uses, and which could be manufactured from a range of biomass types, including wood and forest residues. Economic production and use of biochar may take place within spatial boundaries that contrast greatly in total area and patchiness. At the moment, however, biochar is generally considered at a project level and assessed quite narrowly from the perspective of soil or crop effects or energy yield. This chapter presents a set of scenarios for how biomass from trees grown in different contexts might lead to production of biochar used and deployed...

  4. Business, development and inclusive supply chains. Exploring pathways for the sustainable incorporation of the poor as suppliers in agrifood supply chains

    Borrella Alonso de la Torre, Inmaculada
    El panorama global está cambiando, y esto influye sobre la forma en la que entendemos y tratamos de alcanzar un desarrollo humano sostenible. El crecimiento de la población conlleva una mayor presión sobre los recursos, pero también supone una mayor cantidad de mano de obra y de talento; la concentración en áreas urbanas está cambiando las dinámicas sociales y desafiando los canales de comercialización tradicionales, pero también genera nuevos mercados y fomenta la innovación; los cambios en la economía global están reduciendo los tradicionales desequilibrios de poder entre los países occidentales y el resto del mundo; y las crecientes interconexiones...

    Many prognoses of B2B e-commerce and its potential for developing countries presume that it is a panacea enabling producer firms in these countries to sell their products and services more easily in external markets by reducing the transaction costs they must incur to participate in international trade. Drawing on data from a detailed analysis of 117 B2B e-hubs in the garments/apparel and agriculture/horticulture sectors, it is argued that the kinds of transaction-related support services available at these online trading platforms are more limited in their scope and functionality that is often assumed in the literature on B2B e-commerce development. The...

  9. The productivity of Cenourete®

    Milza M Lana
    a baby carrot-like product, is directly related to the shape and size of the carrot roots (Lana et al., 2007). Cylindrical, long and thin roots result in higher productivity because more segments are obtained per root and less time of abrasion is necessary to shape the segments. Top quality Cenourete ® is obtained from segments that have diameter equal to or lower than 25 mm. Segments with a diameter between 25 and 30 mm can be used to produce a larger Cenourete®, which is more suitable for cooking than for consumption as a raw snack. Root segments larger than 30...

  11. Hydrochemical Analysis and Evaluation of Groundwater Quality in

    Tumkur Taluk; Karnataka State; C. Sadashivaiah; C. R. Ramakrishnaiah; G. Ranganna
    Abstract: Tumkur Taluk is located in the southeastern corner of Karnataka state between 13º 06'30 " to 13º 31 ' 00 " North latitude and 76º 59 ' 00 " to 77º 19 ' 00 " East Longitude. The Taluk spreads over an area of 1043 sq.km falling within the semiarid region and frequently facing water scarcity as well as quality problems. The major sources of employment are agriculture, horticulture and animal husbandry, engaging almost 80 % of the workforce. Water samples are collected from 269 stations during pre-monsoon and 279 locations during post-monsoon of the year 2006, and were...

  12. Americas. South America is considered

    the center of great diversity. Nowadays, more than 3.200 bromeliads species are known, with 70 % of the genus and more than 40 % of the species occurring in Brazil (Grant & Zijlstra, 1998), inhabiting all parts of the country, but having the Atlantic coast as the largest diversity center (Paula, 2001). The different bromeliads genera require different light intensities to their full development. The optimal climatic conditions for each species of bromeliad are those predominant in the center of origin, which determine the degree of shading for them (Carvalho et al., 1998; Carvalho & Rocha, 1999). Therefore, for growing...

    A. Emdad; M. I. Hossain; K. Kabir; M. S. Jahan
    A field experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka with a view to study character association and path analysis in six strawberry genotypes. The trial was laid out in a Randomized Complete Block Design with three replications. Data on crown height, number of flower buds per plant, number of flowers per plant, number of fruits per plant, length and breadth of fruit and fruit yield per plant were collected. All the characters showed significant correlation with fruit yield. Path analysis revealed that crown height, number of flowers per plant and length of fruit had the...

  17. A DATABASE TO AID PROBE DESIGN FOR VIRUS IDENTIFICATION

    Feng-mao Lin; Hsien-da Huang; Yu-chung Chang; Pak-leong Chan
    Viral infection poses a major problem for public health, horticulture and animal husbandry, possibly causing severe health crises and economic loss. Viral infections can be identified by the specific detection of viral sequences in two ways, the first is the amplification-based method, such as using the polymerase chain reaction (PCR), the reverse transcription-polymerase chain reaction (RT-PCR), or nested-PCR, for example, and the second is the hybridization-based approach, such as the use of southern blotting, northern blotting, dot blotting and DNA chips. The former provides the advantages of fast and specific detection and a lower detection limit, but also has some...

    This paper reviews the importance of foreign trainees to farmers whowant to expand their production oflabour-intensivecommodities.Local Japanese youth generally shun farm worker jobs, and Japan is generally closed to low-skilled migrants, but permits farmers, manufacturers andother employers to train and employ young foreigners for up to three years. In Ibaragi Prefecture north of Tokyo, the agricultural cooperatives that provide inputs to farmers and market their vegetables and other produce helped their farmer-members introduce foreign trainees, whoallowed farmers to expand their production andincreased cooperative sales. Trainees must be paid the Japanese mini-mum wage for most of the 36 months they are...
