Light intensity intercepted by the soybean canopy during the reproductive period is an important environmental factor determining soybean yield components and grain yield. A 2-year field experiment was conducted to investigate the effects of light enrichment and its interaction with planting density on yield formation of soybean cultivars. Light enrichment increased seed yield per plant and yie...

co2 enrichment in greenhouse is a suitable way which reduces production time, better growth vigor and also higher plant quality. the main aim of this study was to find out the effects of artificial co2 enrichment under different light levels on rooting of the ornamental foliage codiaeum variegatum. the experiment was planned as a split plot based on a completely randomized design. co2 was consi...

Phytoplankton-grazer dynamics are often characterized by long transients relative to the length of the growing season. Using a phytoplankton-grazer model parameterized for Daphnia pulex with either flexible or fixed algal carbon:nutrient stoichiometry, we explored how nutrient and light supply (the latter by varying depth of the mixed water column) affect the transient dynamics of the system st...

Since they grow nearly exponentially, plants in their juvenile phase can benefit more than mature ones of optimal growing conditions. Transplant production in greenhouses offers the opportunity to optimize growing factors in order to reduce production time and improve transplant quality. Carbon dioxide and light are the two driving forces of photosynthesis. Carbon dioxide concentration can be e...

The impact of anthropogenic eutrophication on the productivity and metabolism of estuarine sediments has received relatively little attention. In this study, we investigated the separate and combined effects of decreased light availability and sediment nutrient enrichment, 2 of the most important impacts of anthropogenic eutrophication, on sediment primary production and metabolism in 2 eutroph...

 Environmental enrichment is one of the methods for improving fish growth performance. In the present trial, the effects of both light color and music on growth performance and survival of goldfish (Carassius auratus) (initial mean weight: 4.15±0.08 g) were investigated for 2 months. Two light color treatments (red light and white light) and three music treatments (M0: without music, M30:30 min...
