INTRODUCTION
Tomatoes (Lycopersicon esculentum) are among the
most widely cultivated and consumed vegetables
worldwide, holding significant economic importance in
global agriculture [10]. The increasing global
population and evolving consumer preferences have
driven a continuous demand for both high yields and
enhanced fruit quality, characterized by attributes
such as soluble solids content (Brix), flavor, and
nutritional value [2, 19, 20, 25, 38]. To meet these
demands efficiently and sustainably, modern tomato
cultivation, particularly in controlled environments like
greenhouses and hydroponic systems, relies heavily on
optimizing various horticultural strategies and
environmental factors.
Greenhouse and hydroponic cultivation offer precise
control over growing conditions, enabling year-round
production
and
protection
against
adverse
environmental factors [20, 21, 27]. However, achieving
optimal yield and quality in these systems is a complex
endeavor, requiring a deep understanding of plant
physiology and its interaction with environmental
parameters. Factors such as planting density, pruning
techniques (pinching), water supply, nutrient solution
composition, and disease management all play critical
roles in determining the final crop performance [1, 4,
7, 16, 29, 30].
The delicate balance between vegetative growth and
reproductive development, often influenced by
resource allocation (dry matter partitioning), is central
to maximizing fruit yield without compromising quality
[8, 14, 15, 18, 21, 33, 34]. Furthermore, the increasing
prevalence of intensive cultivation systems, such as
hydroponics, introduces specific challenges related to
waterborne pathogens and nutrient solution
management [9, 11, 12, 26, 30, 35].
This article aims to provide a comprehensive review of
the key horticultural strategies and environmental
factors that are essential for optimizing both yield and
quality in tomato cultivation. By synthesizing findings
from recent research, we will explore how various
management practices influence plant growth, dry
matter production, fruit characteristics, and overall
crop productivity. The objective is to highlight
integrated approaches that can contribute to more
efficient, sustainable, and high-quality tomato
production systems.

RESULTS AND DISCUSSION
Optimizing tomato yield and quality is a multifaceted
challenge that requires a precise understanding and
control of various horticultural strategies and
environmental factors. The findings from the literature
review highlight several key areas of influence, from
plant management techniques to sophisticated
environmental controls in modern cultivation systems.
Cultivation Techniques and Plant Management
Effective plant management strategies are crucial for
directing plant resources towards fruit development,
thereby enhancing both yield and quality.
•
Planting Density and Pinching: High-density
cultivation systems, often combined with low-node
pinching orders, have been explored as a means to
improve tomato yield [1, 16, 28, 30]. Research indicates
that specific planting densities and the number of leaves
per truss can significantly affect yield components [29,
30]. For instance, studies on cucumber, a related crop,
also show that pinching and lowering influence yield
[16]. The goal is to optimize the balance between
vegetative growth and fruit set, ensuring efficient
resource allocation.
•
Root Restriction: Root restriction is a technique
that can influence plant performance and fruit quality.
Studies have shown its effect on three-truss cultivated
tomatoes in high-density systems, demonstrating its
potential to modify plant growth and resource
partitioning [1]. Similarly, the use of capillary mats and
root restriction sheets has been investigated for
producing high soluble solids tomatoes [29].
•
Grafting: Grafting onto vigorous rootstocks,
such as 'Maxifort', has been shown to improve the yield
and dry matter production of tomato cultivars like the
Japanese 'Momotaro York' [17]. Grafting can enhance
disease resistance and nutrient uptake, contributing to
overall plant health and productivity.
•
Leaf Area Management: The estimation of leaf
area and light-use efficiency through non-destructive
measurements is vital for growth modeling and
determining the recommended leaf area index in
greenhouse tomatoes [32]. Optimizing leaf area ensures
efficient light interception for photosynthesis, which
directly impacts dry matter production and,
consequently, yield.
Water and Nutrient Management in Hydroponics and
Salinity Control
Precise control over water and nutrient supply is
paramount in modern tomato cultivation, especially in
hydroponic
systems,
where
nutrient
solution
management directly affects plant growth, yield, and
fruit quality.
•
Water Stress and Irrigation Management:
Moderate water deficit can be strategically applied to
improve fruit quality, particularly soluble solids content,
without severely compromising yield [2, 4, 19, 27].
However, severe water stress can negatively impact
yield and fruit growth [8, 27]. Effective irrigation
management techniques, often based on solar radiation
or plant weight measurements using load cells, are
crucial for high-quality tomato production [19, 28, 30].
The interplay between water deficit, soil texture, and

The American Journal of Horticulture and Floriculture Research
tomato variety also influences fruit quality [27].
•
Electrical Conductivity (EC) of Nutrient
Solution: The electrical conductivity (EC) of the
nutrient solution is a critical parameter in hydroponics,
directly influencing nutrient uptake and osmotic stress.
Increasing the EC, often by adding salts, is a common
strategy to enhance fruit quality, particularly soluble
solids (Brix), by inducing mild water stress [5, 6, 7, 13,
20, 25, 26, 31, 36, 38]. However, there's a delicate
balance, as excessively high EC can reduce yield [6, 7,
8, 13, 25, 31, 36, 38]. Studies have focused on
optimizing EC levels at different growth stages and
during specific periods to maximize quality without
significant yield penalties [19, 20, 24, 25, 28, 30, 31, 36,
38]. Modeling and prediction of soluble solids based on
drainage EC have also been developed [20].
•
Nutrient Concentration and Composition:
Beyond EC, the specific concentrations and
composition of nutrient elements in the solution affect
plant growth, nutrient uptake patterns, and fruit
quality [24, 39]. Research has explored the impact of
different nutrient strengths on yield and mineral
concentration in fruits [24].
•
Recirculating Systems and Disinfection:
Recirculating hydroponic systems conserve water and
nutrients but pose a risk of pathogen accumulation [9,
26, 30]. Effective disinfection methods, such as
membrane filtration (e.g., polyvinylidene fluoride
ultrafiltration membranes, "Torayfil HFM") [20, 26]
and other disinfection systems [9, 30], are essential for
preventing the spread of waterborne plant pathogens
like Pythium species and Ralstonia solanacearum [3, 9,
11, 12, 26, 30, 35]. Organic hydroponic systems have
also shown promise in suppressing bacterial wilt
disease [12].
Dry Matter Production and Yield Modeling
Understanding dry matter production and its
allocation within the plant is fundamental for
optimizing yield. Dry matter production refers to the
total biomass accumulated by the plant, and its
partitioning to fruits is key for high yields [8, 14, 15, 18,
21, 33, 34].
•
Modeling and Prediction: Empirical yield
prediction models based on dry matter production
have been developed for crops like sweet pepper [21,
33, 34]. Similar modeling approaches are crucial for
greenhouse tomatoes to predict and improve yield,
especially in year-round production systems based on
short-term, low truss crop management [20, 21, 33].
Non-destructive measurements can be used for
estimating dry matter production and yield prediction
[21, 33].
•
Sink Strength: The concept of "fruit sink
strength"
—
the ability of fruits to attract assimilates
(sugars) from other parts of the plant
—
is critical.
Factors affecting fruit set ratio and the allocation of dry
matter to fruit are closely studied to ensure that
increased total dry matter translates into higher fruit
yield, even under conditions like CO2 elevation [18, 21].
Fruit Quality Enhancement
The primary goal of many modern tomato cultivation
systems is to produce fruits with high soluble solids
content (Brix), which is a key indicator of flavor and
quality.
•
Salinity and Soluble Solids: As discussed,
moderate salinity stress, often achieved by controlling
the EC of the nutrient solution, is a widely used
technique to increase soluble solids in tomato fruits [5,
6, 8, 13, 20, 25, 31, 36, 38]. This is due to osmotic
adjustment and changes in assimilate metabolism
within the fruit [31, 38]. The duration of salinity
treatment and planting density can also influence fruit
size and sugar content [31].
•
Drip Fertilization: Drip fertilization systems can
be used to precisely control nutrient delivery,
contributing to stable production of high soluble solids
tomatoes [24].
•
Low Node-Order Pinching and High-Density
Planting: These combined techniques have been
demonstrated to produce high soluble solids fruits,
particularly in Japanese cultivars, by optimizing plant
architecture and resource allocation [14, 28, 30].
•
Comparison of Stresses: Studies have compared
the chemical composition of tomato fruit grown under
water and salinity stresses, providing insights into the
physiological
responses
that
lead
to
quality
improvements [38].
Overall Trends and Future Directions
The field of tomato cultivation is continuously evolving
with new technologies and integrated approaches.
•
Year-Round Production: Research focuses on
optimizing systems for year-round production of high
soluble solids tomatoes, often involving low node-order
pinching and high-density planting [20, 21].
•
Advanced Technologies: Innovations like the
Imec hydrogel membrane technology for advanced
agro-technology are emerging [23]. The use of heat
insulation films in subtropical areas is also being
explored to mitigate heat stress and improve yield and
quality [27].
•
Integrated Management: The trend is towards
integrated management systems that combine precise
control over environmental factors (e.g., temperature,

CO2, light, humidity) with optimized horticultural
practices to maximize resource use efficiency and
product quality [14, 27, 29, 30, 32].
•
Disease Management: Continued research
into biological control and eradication of plant
pathogens in irrigation water is crucial for sustainable
hydroponic systems [3, 9, 11, 12, 26, 30, 35].
These advancements collectively aim to ensure the
stable and high-quality production of tomatoes to
meet global market demands.
CONCLUSION
Optimizing yield and quality in tomato cultivation is a
dynamic and evolving field, driven by scientific
advancements and technological innovations. This
review has highlighted the critical influence of various
horticultural strategies and environmental factors on
tomato plant performance and fruit characteristics.
Precise plant management techniques, including
planting density, pinching orders, root restriction, and
grafting, are essential for directing plant resources
efficiently. Concurrently, sophisticated water and
nutrient management, particularly in hydroponic
systems, through the careful control of water stress
and nutrient solution electrical conductivity, plays a
pivotal role in enhancing fruit quality, especially
soluble solids content.
The integration of these practices, supported by
advanced modeling for dry matter production and
yield prediction, allows for a more scientific and
predictable approach to cultivation. Furthermore,
robust
disease
management
strategies
are
indispensable for the sustainability of intensive,
recirculating systems. The continuous focus on year-
round production and the adoption of cutting-edge
technologies underscore the industry's commitment to
meeting the growing global demand for high-quality
tomatoes.
Ultimately, achieving optimal yield and quality in
tomato cultivation necessitates an integrated and
adaptive approach, where environmental parameters
are precisely controlled and horticultural practices are
finely tuned to plant physiological responses. Future
research should continue to explore the synergistic
effects of these factors, develop more accurate
predictive models, and investigate novel sustainable
practices to enhance resource efficiency and resilience
against environmental challenges. This ongoing
scientific endeavor is crucial for ensuring the future of
high-quality tomato production worldwide.
