Effects of Different Light Sources on Shoot to Root Ratio and Intumescence Incidence in Tomato Seedlings Grown in a Commercial Closed Seedling Production System

Yoko Miyama

Volume 10, Issue 2 , January 2023, Pages 1-8


  Intumescence is a physiological disorder in which cell walls are disrupted. Intumescence causes leaf deformation, browning and defoliation, and commonly affects tomato plants. This is a limitation in seedling production. The causes of intumescence are not known; however, ultraviolet (UV) deficiency is ...  Read More

Impact of Irrigation and Decreased Light Level by Shade Crop on the Establishment of Cacao Plants

Vences C Valleser; Glenn Dayondon; Andrew Melencion

Volume 10, Issue 2 , January 2023, Pages 17-24


  The massive establishment of new plantations supported by the basic needs of a crop are technical approaches for an increased crop productivity. Water and decreased light levels by shade (i.e. intercropping) are considered basic needs of cacao plants, especially during the early vegetative growth stage. ...  Read More
