    Nowadays , demographic pressure on water and land resources is progressively increasing and their sustainability features have increasingly been under threat so these resources are required to using effectively. Large part of food requirements meet from irrigable area.

    Günümüzde arazi ve su kaynaklarına olan demografik baskının artması ve su kaynaklarının sürdürebilir olma niteliklerinin gün geçtikçe tehlikeye girmesi, su kaynakların etkin kullanımı ihtiyacını arttırmaktadır. Gıda ihtiyacının büyük bir kısmı sulanabilir alanlardan sağlanmaktadır.

    Nineteen microsatellite markers were used to fingerprint a set of 19 potato landraces from the island of La Palma (Canary Islands). These landraces represent relicts of early introductions from South America, although most are commonly cultivated by local farmers. The SSR primers detected 62 polymorphisms, 13 of which were present in all landraces. Several accession- and group-specific markers were detected. Jaccard similarity coefficients were estimated from the molecular data and UPGMA cluster analysis was performed. Some cultivars with related common names clustered together.

    This paper analyses the impact of the Common Agricultural Policy (CAP) and macroeconomy on land use changes in the EU. Three scenarios are simulated up to 2030: baseline, macro scenario and policy scenario. Simulation results indicate that GDP leads to a stronger effect on land use changes than the CAP. Stronger changes in land use are observed at the crop disaggregated level than at the aggregated level for the total agricultural area, arable land, grassland and permanent crops.

    The effects of subsidies on the development of organic farming (OF) in the Czech Republic and in some selected EU countries are analysed in this article. The level of subsidies for OF in the Czech Republic is continuously increasing. In 1998, the total amount of subsidies was 48 million CZK, whereas in 2004, it increased to nearly 277 million CZK. The increase of subsidies led to an increase in the number of organic farms as well as the area under OF.

    Resource-poor farmers in developing nations cultivate marginal lands, thereby exacerbating the problem of soil degradation through poor plant growth and ground coverage. An assessment of ground cover under such a practice will provide a guideline for soil conservation. Ground cover by leguminous cover crops (e.g., Mucuna pruriens, Pueraria phaseoloides and Vigna unguiculata), associated with yam, maize and rice was measured in three different experiments in southwestern Nigeria using beaded-string method while leaf area was measured using a flat-bed scanner.
