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 ... -
Deep Learning in Hyperspectral Image Reconstruction from Single RGB images—A Case Study on Tomato Quality Parameters
Zhao, Jiangsan; Kechasov, Dmitry; Rewald, Boris; Bodner, Gernot; Verheul, Michel; Clarke, Nicholas; Clarke, Jihong Liu (Peer reviewed; Journal article, 2020-10-07)Hyperspectral imaging has many applications. However, the high device costs and low hyperspectral image resolution are major obstacles limiting its wider application in agriculture and other fields. Hyperspectral image ... -
Organic Waste-Based Fertilizer in Hydroponics Increases Tomato Fruit Size but Reduces Fruit Quality
Kechasov, Dmitry; Verheul, Michel; Paponov, Martina; Panosyan, Anush; Paponov, Ivan (Peer reviewed; Journal article, 2021-06-23)In regions with intensive agricultural production, large amounts of organic waste are produced by livestock animals. Liquid digestate from manure-based biogas production could potentially serve as fertilizer if integrated ... -
Supplemental Light-Emitting Diode Inter-Lighting Increases Tomato Fruit Growth Through Enhanced Photosynthetic Light Use Efficiency and Modulated Root Activity
Paponov, Martina; Kechasov, Dmitry; Lacek, Jozef; Verheul, Michel; Paponov, Ivan (Peer reviewed; Journal article, 2020-01-10)We investigated the effect of supplemental LED inter-lighting (80% red, 20% blue; 70 W m−2; light period 04:00–22:00) on the productivity and physiological traits of tomato plants (Flavance F1) grown in an industrial ... -
Test of biostimulant effect of microalgae (Phaeodactylum tricornutum) on basil (Ocimum basilicum)
Øgaard, Anne Falk; Umetani, Ikumi; Kechasov, Dmitry (NIBIO Rapport, Research report, 2023)This report shows results from an experiment where it was investigated whether a powder of freeze-dried microalgae (Phaeodactylum tricornutum) had a biostimulating effect on the growth and content of nutrients and antioxidants ...
