    • Application of variable rate fertilizer in a commercial apple orchard 

      Liakos, V.; Tagarakis, A.; Vatsanidou, A.; Fountas, S.; Nanos, G.; Gemtos, T. (2013)
      The spatial variability of yield in an apple orchard is high due to the inherent soil variability and the impact of the environment on the trees. One practice of precision agriculture is the variable rate application (VRA) ...

    • Delineation of management zones in an apple orchard in Greece using a multivariate approach 

      Aggelopooulou, K.; Castrignano, A.; Gemtos, T.; De Benedetto, D. (2013)
      Management zone (MZ) delineation is important for the application of Precision Agriculture because farm management decisions are based on it. Several factors were used for the MZ delineation including crop and soil ...

    • Farm machinery management information system 

      Fountas, S.; Sorensen, C. G.; Tsiropoulos, Z.; Cavalaris, C.; Liakos, V.; Gemtos, T. (2015)
      Management of farming operations is currently rapidly changing toward a systems perspective integrating the surroundings in terms of environmental impact, public entities and documentation of quality and growing conditions. ...

    • A flow-shop problem formulation of biomass handling operations scheduling 

      Bochtis, D. D.; Dogoulis, P.; Busato, P.; Sorensen, C. G.; Berruto, R.; Gemtos, T. (2013)
      Currently, the planning of the biomass collection operations is performed relying on the contractor's experience without the use of any dedicated planning tool. It is expected that more explicitly formulated planning tools ...

    • Management information system for spatial analysis of tractor- implement draft forces 

      Tsiropoulos, Z.; Fountas, S.; Gemtos, T.; Gravalos, I.; Paraforos, D. (2013)
      With the recent increases in fuel costs, producers are searching for ways to minimize costs and to increase productivity. The ability to monitor and collect data about tractor/implement performance can benefit farm machinery ...

    • Management strategies and practices for precision agriculture operations 

      Fountas, S.; Pedersen, S.; Sorensen, C.; Chatzinikos, A.; Pesonen, L.; Basso, B.; Vougioukas, S.; Nash, E.; Gemtos, T.; Blackmore, S. (2009)
      This paper presents a holistic farm management system combining formal management strategies, personal management goals and the technology used. The personal management goals have been identified and analysed. Six field ...

    • Management zones delineation using fuzzy clustering techniques in vines 

      Tagarakis, A.; Liakos, V.; Fountas, S.; Koundouras, S.; Aggelopoulou, K.; Gemtos, T. (2011)
      This paper presents the results of applying precision agriculture in a 1 ha commercial vineyard in Greece in 2009 and 2010. A field elevation map was produced using RTK-GPS. Soil electrical conductivity was measured using ...

    • Transplanting Machine Operation Analysis 

      Natsis, A.; Fountas, S.; Gemtos, T. (2011)
      Transplanting has been used for most vegetables and ornamental plants to achieve better establishment and early maturing of the crops. Manual transplanting is slow and labour intensive. Semiautomatic transplanters are a ...

    • Using laser scanner to map pruning wood in vineyards 

      Tagarakis, A.; Liakos, V.; Chatzinikos, T.; Koundouras, S.; Fountas, S.; Gemtos, T. (2013)
      Management zones in vineyards may be delineated by examining the spatial variability of various biophysical factors related to grapevine performance, such as vegetation indices. Among measurements of vine vigour, the ...

    • Wireless sensor network for precision agriculture 

      Tagarakis, A.; Liakos, V.; Perlepes, L.; Fountas, S.; Gemtos, T. (2011)
      Sensors are very useful in agriculture. Irregular or insufficient rainfall can be a serious limitation to the final yield, causing low yields and even crop failure. Moreover the total amount of water cannot be assessed ...

    • Yyield prediction in a commercial apple orchard by analyzing RGB and multi-spectral images of trees during flowering period 

      Liakos, V.; Tagarakis, A.; Aggelopoulou, K.; Kleftaki, X.; Mparas, G.; Fountas, S.; Gemtos, T. (2011)
      The objective of the research was to study the spatial variability in an apple orchard and to develop methods for predicting the variation of the final yield. RGB and multi-spectral images of part of the trees were taken ...
