The controlled environment of greenhouses allows for optimized conditions such as temperature, humidity, and CO2 levels, which are crucial for the growth and productivity of cherry tomatoes. For instance, the use of crop residues and animal manure composting (CRAM) in greenhouses can double the CO2 concentration, leading to a 38% increase in yield and improved fruit quality, including higher concentrations of soluble sugars and ascorbic acid (Figure 5) (Karim et al., 2020). Additionally, greenhouse conditions facilitate the precise management of irrigation and fertilization, which are critical for maximizing yield and fruit quality (He et al., 2021).

However, open field methods can be more cost-effective and accessible for small-scale farmers. The use of organic mulches in open field systems has been shown to improve growth indicators such as leaf area, plant height, and fruit weight, thereby enhancing productivity (Cipriani et al., 2020). Despite these benefits, the lack of controlled conditions in open fields often results in lower overall yields compared to greenhouse cultivation. 5.2 Use of support structures and pruning techniques Support structures and pruning techniques are essential for optimizing the growth and yield of cherry tomatoes. Sucker pruning and old leaf removal have been found to significantly improve plant height, fruit size, and overall yield. For example, sucker pruning resulted in the highest plant height and fruit size, while old leaf pruning led to the highest number of fruits per plant and yield per hectare (Ahmad et al., 2017). These techniques help in managing the plant's energy distribution, ensuring that more resources are directed towards fruit production rather than vegetative growth. Moreover, the use of support structures such as trellises can prevent the plants from sprawling on the ground, reducing the risk of disease and pest infestations. This is particularly important in greenhouse settings where space
