Simulation of crop water and mineral relations in greenhouse soilless culture
A composite model was developed for water and mineral relations of greenhouse tomato (Solanum lycopersicum L.) cultivated in semi-closed or open soilless (rockwool) culture. The model simulated on a daily basis: (i) the evolution of crop leaf area index and water uptake using empirical equations; and (ii) the variations of ion concentrations and electrical conductivity (EC) in the recirculating...
متن کاملGreenhouse tomato limited cluster production systems: crop management practices affect yield.
Limited-cluster production systems may be a useful strategy to increase crop production and profitability for the greenhouse tomato (Lycopersicon esculentum Mill). In this study, using an ebb-and-flood hydroponics system, we modified plant architecture and spacing and determined the effects on fruit yield and harvest index at two light levels. Single-cluster plants pruned to allow two leaves ab...
متن کاملMineral deficiencies influence on tomato leaves: pigments, hydrogen peroxide and total phenolic compounds contents
The detection of hydrogen peroxide, chlorophyll pigments, anthocynin, carotenoids, total phenolic compounds and lipid peroxidation levels as potential stress signaling molecules in tomato (Lycopersicon esculentum Mill.) leaves in response to specific mineral deficiency were studied. The stress signaling molecules were measured in the plant leaves at different growth time points cultured in spec...
متن کاملDynamic Modeling of Economic System in Iran
The long term goal attaining of economic system management requires the establishment of a dynamic framework to integrate multiple perspectives. This article considers the problem of economic development in macro level. As economic systems are complex adaptive systems composed of numerous numbers of components of dynamic and multidimensional nature, dynamics method is applied in this research. ...
متن کاملSimulating Growth and Development of Tomato Crop
Crop models are powerful tools to test hypotheses, synthesize and convey knowledge, describe and understand complex systems and compare different scenarios. Models may be used for prediction and planning of production, in decision support systems and control of the greenhouse climate, water supply and nutrient supply. The mechanistic simulation of tomato crop growth and development is described...
