Choosing carefully plant density and spacing as these are critical to ensure crops make best use of environmental, especially light conditions, so that yield potentials are reached.Maintaining optimum soil pH to ensure nutrients are readily available. Using herbicides or cultivation to remove any weed competition.
Managing carefully temperature and light intensity as they are critical at flowering, to ensure unhindered flower formation, good pollination, fertilization and fruit set.
Avoiding high temperature stress. This can lead to bud abscission prior to flowering. The same conditions at flowering will lead to abnormal flower development and death.
Minimizing the competitive effects of excessive vegetative development with leaf pruning most commonly by removing the lower leaves to allow more light to reach the ripening fruit. This also provides better air movement around the lower stem, reducing the impact of stem diseases. It is important to avoid excessive leaf pruning in high light environments as the crops can be at risk of sunscald.
Maintaining a leaf area index of 3 to maximize fruit growth. Hand thinning of tomatoes on the end of a truss ensures more evenly sized, larger fruit.
Using growth regulators such as auxins at anthesis to help stimulate fruit set and increase fruit size, specially under low light and low temperature conditions.
Controlling salinity by good leaching practices within the root environment and managing water supply to maximize growth and ensure good nutrient availability.
