A tailor-made crop growth model for the tomato production systems in Colombia

Abstract: Potential crop models simulate the plant growth under non- limiting biophysical conditions with no other factor than the climate to which the plants are exposed to. These models may fail to adequately represent the crop performance if they are not

Combined effect of green-colored covers and shading on the growth of sisal (Furcraea hexapetala) plants

Abstract: Plants have the ability to respond in different ways to the quality of light, its intensity, and the combination of both. In addition, chlorophyll absorbs light in the blue and red bands of the spec - trum, but green and infrared light are poorly absorbed o

Fitting of photosynthetic response curves to photosynthetically active radiation in oil palm

Abstract: Light saturation curves represent the response of the net photosynthetic rate to the photosynthetically active radiation. These curves were obtained from individual leaves of oil palm genotypes ( Elaeis guineensis, E. oleifera and the O×G intersp

Effect of deficit irrigation on yield and quality of pear (Pyrus communis cv. Triumph of Vienna)

Abstract: Crop demands for irrigation require different technologies to optimize the use of water. Regulated Deficit Irrigation (RDI) is a strategy that enables a significant reduction of water application without affecting the crop yield and quality, with the advan
