SPATIAL DISTRIBUTION OF QUALITATIVE CHARACTERISTICS AND PRODUCTION FACTORS OF KIWIFRUIT AT "BEIRA LITORAL", PORTUGAL

Objective of the present research was to generate information about the evolution of production factors and qualitative characteristics of 100 geo-referenced orchards of Beira Litoral-Portugal during three consecutive years. Graphical interpretation of quantitative and qualitative characteristics of kiwifruit production was done using GIS, geostatistics. Maps of biophysical characteristics of the region were then related to the areas of higher production and quality and it was studied their evolution over time. Those maps help to make decisions about harvesting time or localized correction of production factors and to choose the adequate location for vineyard installation in the region. Despite our enthusiasm for this technology, we are not proposing that it is a solution to all crop management problems or that it is appropriate for every operation. Meanwhile, we believe that the use of GIS and geostatistics provides a tool for sustainable production.
