Review of optimum temperature, humidity, and vapour pressure deficit for microclimate evaluation and control in greenhouse cultivation of tomato: a review

Abstract

Greenhouse technology is a flexible solution for sustainable year-round cultivation of Tomato (Lycopersicon esculentum Mill), particularly in regions with adverse climate conditions or limited land and resources. Accurate knowledge about plant requirements at different growth stages, and under various light conditions, can contribute to the design of adaptive control strategies for a more cost-effective and competitive production. In this context, different scientific publications have recommended different values of microclimate parameters at different tomato growth stages. This paper provides a detailed summary of optimal, marginal and failure air and root-zone temperatures, relative humidity and vapour pressure deficit for successful greenhouse cultivation of tomato. Graphical representations of the membership function model to define the optimality degrees of these three parameters are included with a view to determining how close the greenhouse microclimate is to the optimal condition. Several production constraints have also been discussed to highlight the short and long-term effects of adverse microclimate conditions on the quality and yield of tomato, which are associated with interactions between suboptimal parameters, greenhouse environment and growth responses.

An Analysis of Global Research Trends on Greenhouse Technology: Towards a Sustainable Agriculture

“…The greenhouse industry is continually developing new strategies and technologies to resolve specific limitations of the crops, reducing any related environmental impact and adapting to the new market requirements [35]. Therefore, soilless crops [36]; the comprehensive control of the factors that constitute the microclimate inside the greenhouse [47,48]; the creation of vertical agroecosystems that can be located in urban environments [49]; the development of specific environmentally sustainable solutions for supplying greenhouse production with renewable energy [50,51]; the development of new materials and structures capable of optimising production [52,53]; etc. are all now possible.…”

Investigation of energy-efficient solid desiccant system for wheat drying

“…Grains drying at industrial level requires safe storage limit of moisture contents, otherwise, spoiling of grains may be the development of molds and fungus. Therefore, the allowable safe storage time is calculated by using Equation (13). Table 1 represents the allowable safe storage time for both drying methods at different supply air conditions.…”

“…temperature and humidity control systems [2] . For example, in case of greenhouses, several new concepts of CEA such as vertical farming and plant factories are presented in the literature [12,13] . Some of the research on the sustainability and clean energy application for high-tech greenhouses and plant factories can be found via the analysis of microclimate control and environment modelling [14][15][16][17][18][19][20] .…”

Application of the Climograph for the Greenhouse Plan of Subtropical and Tropical Regions

“…The purpose of a greenhouse is to maintain an optimum environment for plant production. The microclimate in the greenhouse is mainly influenced by the local weather, structure and covering materials of greenhouses, and controlling equipment [1].…”
