• Artificial top-light is more efficient for tomato production than inter-light 

      Verheul, Michel; Maessen, Hendricus; Paponov, Martina; Panosyan, Anush; Kechasov, Dmitry; Naseer, Muhammad; Paponov, Ivan (Peer reviewed; Journal article, 2022-09-17)
      Studies of whole-plant responses of tomato to light environments are limited and cannot be extrapolated from observations of seedlings or short-term crops in growth chambers. Effects of artificial light sources like high ...
    • Bio-economic evaluation of greenhouse designs for seasonal tomato production in Norway 

      Naseer, Muhammad; Persson, Tomas; Righini, Isabella; Stanghellini, Cecilia; Maessen, Hendricus; Verheul, Michel J. (Peer reviewed; Journal article, 2021-11-20)
      Greenhouses are complex systems whose size, shape, construction material, and equipment for climate control, lighting and heating can vary largely. The greenhouse design can, together with the outdoor weather conditions, ...
    • Bioeconomic evaluation of extended season and year-round tomato production in Norway using supplemental light 

      Naseer, Muhammad; Persson, Tomas; Righini, Isabela; Stanghellini, Cecilia; Maessen, Hendricus; Ruoff, Peter; Verheul, Michel (Peer reviewed; Journal article, 2022-02-28)
      CONTEXT For high latitude countries like Norway, one of the biggest challenges associated with greenhouse production is the limited availability of natural light and heat, particularly in winters. This can be addressed by ...
    • A greenhouse climate-yield model focussing on additional light, heat harvesting and its validation 

      Righini, Isabella; Vanthoor, Bram; Verheul, Michel; Naseer, Muhammad; Maessen, Hendricus; Persson, Tomas; Stanghellini, Cecilia (Peer reviewed; Journal article, 2020-03-31)
      A greenhouse climate-crop yield model was adapted to include additional climate modification techniques suitable for enabling sustainable greenhouse management at high latitudes. Additions to the model were supplementary ...
    • Life cycle assessment of tomato production for different production strategies in Norway 

      Naseer, Muhammad; Persson, Tomas; Hjelkrem, Anne-Grete Roer; Ruoff, Peter; Verheul, Michel (Peer reviewed; Journal article, 2022-08-30)
      The availability of fresh vegetables grown in greenhouses under controlled conditions throughout the year has given rise to concerns about their impact on the environment. In high latitude countries such as Norway, greenhouse ...
