Comprehensive Study

The fundamentals of an interdisciplinary approach to the design of greenhouse production systems are considered, in which biological objects (plants and humans) are present. The conceptual approach of the software solution is analyzed, synthesizing on the basis of the objectoriented concept such directions as disciplines on the construction of greenhouse production, dynamic simulation models, geoinformation systems. Based on the study of this issue, the conclusion was made about the advisability of applying an interdisciplinary approach for a comprehensive study of the projected complex biotechnical systems of greenhouse production.

Average Temperature

Temperature management has emerged as an important tool for plant height control in greenhouse production systems. This is particularly important in vegetable transplant production where chemical controls for plant height are limited or not legal. Plant height is a function of the number of nodes and the length of each internode, and both are strongly influenced by greenhouse temperatures. Node number, or formation rate, is primarily a function of the average greenhouse temperature, increasing as the average temperature increases. Internode length is strongly influenced by the relationship between the day and night temperature, commonly referred to as DIF (day temperature - night temperature). As DIF increases, so does internode length in most plant species studied. Although the nature and magnitude of temperature effects vary with species, cultivar, and environmental conditions, these two basic responses can be used to modify transplant growth. Although data are limited, controlling transplant height with temperature does not appear to adversely influence plant establishment or subsequent yield.

Further Development

Precision agricultural greenhouse systems indicate considerable scope for improvement of irrigation management practices, since growers typically irrigate crops based on their personal experience. Soil-based greenhouse crop irrigation management requires estimation on a daily basis, whereas soilless systems must be estimated on an hourly or even shorter interval schedule. Historically, irrigation scheduling methods have been based on soil or substrate monitoring, dependent on climate or time with each having both strengths and weaknesses. Recently, plant-based monitoring or plant reflectance-derived indices have been developed, yet their potential is limited for estimating the irrigation rate in order to apply proper irrigation scheduling. Optimization of irrigation practices imposes different irrigation approaches, based on prevailing greenhouse environments, considering plant-water-soil relationships. This article presents a comprehensive review of the literature, which deals with irrigation scheduling approaches applied for soil and soilless greenhouse production systems. Irrigation decisions are categorized according to whether or not an automatic irrigation control has the ability to support a feedback irrigation decision system. The need for further development of neural networks systems is required.

Abstract While there is a wide range of potentially profitable crops which can be grown in hydroponics under protected cultivation, greenhouse production is dominated by fruiting crops such as tomatoes, cucumber, capsicum and strawberries, and vegetative species such as lettuce, salad and leafy greens, herbs and specialty crops like microgreens. This chapter summarizes information on a selected range of common hydroponic crops to give basic procedures for each and an outline of the systems of production. These crops include tomato, capsicum or sweet bell pepper, cucumber, lettuce and other salad greens, strawberry and rose. Information is given on their hydroponic production systems and environment, propagation, plant density, pruning, pollination, fruit growth, crop nutrition, pests, diseases, disorders, harvesting and postharvest handling.
