Adding more light improves the lighting conditions, which is a crucial factor in enhancing the color development of sweet peppers. Adequate light exposure helps stimulate the production of pigments, leading to better coloring. During the fruiting stage, it's essential to promptly remove old and yellowing leaves from the lower parts of the plant, as well as any non-fruit-bearing or disorganized branches. This practice ensures good air circulation and light penetration both between plants and within the plant structure, promoting even color development. However, during periods of high temperature and intense sunlight, it's important not to remove too many leaves around the fruits, as this can cause sunburn and damage to the plant.
In addition, during the color change phase of sweet peppers, it's recommended to clean the greenhouse film regularly to maintain its transparency and maximize light transmission. Clearing dust and debris from the cover allows more sunlight to reach the plants, further supporting the ripening process.
Cooling the greenhouse environment is also vital for optimal growth and coloring. The ideal temperature for sweet pepper development is around 25°C, which supports the formation of lycopene—the pigment responsible for the red color in peppers. If temperatures rise above 35°C, especially during midday, the peppers may develop unevenly or fail to color properly. To manage this, early ventilation should be implemented. At around 9 a.m., open the upper vents and front-side vents to lower the internal temperature. Additionally, night temperatures in the greenhouse are often too high, so it's important to reduce them to create a larger day-night temperature difference. A difference of at least 10°C helps increase the accumulation of sugars and other photosynthetic products, which in turn enhances fruit coloration. Once the afternoon temperature drops to about 18°C, close the vents to maintain an appropriate nighttime temperature.
Proper watering and fertilization are also key to supporting the coloring process. Applying top-dress fertilizers rich in potassium and boron can significantly improve color development, while excessive nitrogen should be avoided, as it can delay ripening. The recommended ratio of potash fertilizer to nitrogen fertilizer is typically around 2:1, ensuring balanced nutrition that supports both growth and fruit quality. Combining these practices with proper light and temperature management will lead to healthier, more colorful sweet peppers.
