    The constat growth of the Earth’s population brings with itself a higher demand for food and protein not only in human nutrition but also for the feeding of livestock. Currently, the feed industry is mainly built onseed-based protein, wherethebaseplant is soybean, which is large lycovered by imports in Hungary, similar toother European countries. However, the long-term economically sustainable lifestock breeding demandschanges which has also worked out strategies. An alternative protein sources could be green leafy plants.

    In current work the Jerusalem artichokes as an alternative source of protein was studied, compared to alfalfa as a valuable protein plant. Our results indicate that fiber fraction ofJerusalem artichoke shootswas 34 to 37% after pressing in the autumn period while alfalfa slightly lower values were obtained (30%). On the other hand extracted green leaf protein concentration was higher in alfalfa than in Jerusalem artichoke. Along with this higher protein content could be measured from the leaf protein concentration of alfalfa and almost each amino acids were more, as well comparing to Jerusalem artichoke.

    Overall, the alfalfa proved to be advantageous as expected both in leaf protein extraction efficiency, both regarding the content of the protein in the Jerusalem artichoke. However, considering aminoacid composition and green biomass production, Jerusalem artichokecould be a promisingplant species asplant protein sourceinthefuture.

  • Will there be a horticultural triangle (cluster)? Thoughts about the reconstruction of the Hungarian horticulture between two European regions

    The authors of this study seek the answer to the question how to develop, in the first decade or decades of the 21st century, the university-level
    horticultural scientific training, the horticultural innovation and the scientific co-operation between companies and universities in Debrecen and
    in the North Great Plain Region and – in a wider sense – in Hungary to a standard being competitive even in European terms. With the synthesis
    of the prospects of past, present and future, they drew the following conclusions. The reconstruction of agriculture, horticulture and food industry
    is a part of reforming Hungary's countryside. Horticulture, producing high added value, will be able to decisively contribute to the plan whereas
    the value presently produced in an agriculturally cultivated area of 1,000 euros/hectare can reach 2,000 to 3,000 euros in the next two decades.
    A necessary and indispensable precondition to achieving this is the strengthening of the innovation output of the Hungarian horticultural sector.
    Despite the numerous technical criticisms formulated in connection with the serious problems of Hungarian agricultural and horticultural
    scientific innovation, no progress has been made in this field for the past one and a half decade. The scientific research of this topic hardly
    continued or did not continue at all, the up-to-date surveys and in-depth analyses were missing. The objective, basic principles and tasks of the
    Act CXXXIV of 2004 (TTI) enacted concerning research-development and technological innovation are clear and progressive. The co-operation
    between the National Research Technology Office and the Hungarian Academy of Sciences, the setting up of the Innovation Fund are heartening
    opportunities. These – along with the new Higher Education Bill to be passed – may as well be suitable for restarting the Hungarian agricultural
    and horticultural scientific innovation. In our opinion, this requires a new, well-considered national agricultural programme, which can be
    conceived in the framework of the "Ferenc Entz National Horticultural Plan" proposed by us for horticulture. In the most eastern Hungarian
    university knowledge centre, at the University of Debrecen, the continuing of the horticultural scientific innovation strategy started in the last
    decade may be the focal point and generator of the development of the so-called "Hungarian Horticultural Triangle”, or "Hungarian
    Horticultural Cluster". This region comprises the Northern and Southern Great Plain Regions and the area between the Danube and Tisza
    Rivers. Here, about 70 to 75% of the total Hungarian horticultural commodity stock is produced. The objective of the HORT-INNOTECH
    DEBRECEN programme planned in 2004 by the University of Debrecen, Centre of Agricultural Science is to establish the horticultural scientific
    research-development and technological innovation structure and knowledge base of the Hungarian Horticultural Triangle / Hungarian
    Horticultural Cluster. In harmony with this, the objectives are to bring about competitive, new horticultural products, to improve the conditions
    of utilising them, to enhance the competitiveness of enterprises based on technological innovation, to make use of the research-development and
    innovation opportunities available in the regions in an efficient manner, to as full extent as possible, to encourage the creation of places of
    employment producing high added value in the field of horticulture, to improve the technical skills of those employed in horticultural researchdevelopment and to promote their enhanced recognition by the society.

  • Utilization of Okra (Abelmoschus esculentus L. Moench.)

    Okra is warm season crop native to Africa. Presently it is widely grown in the northeastern parts of Brazilia, both northen, and western parts of Africa, southeast Asia, and in the eastern parts of the Mediterraneum. In Hungary it is a rarity. It’s adaptation to Hungary began about 40 years ago.The optimal sowing time under Hungarian climatic conditions is middle of May. The harvests is started – depending on the weather – first, by the middle of July, and picking continues until the first of September.
    According to our results, seed soaking, sowing under a perforated foil sheet-covered trench (2 weeks earlier the normal sowing time), and 55-65 g thousand weight seeds are favourable.
    The harvest period under Hungarian circumstances is appr. one and half months.
