Pineapple is one of Taiwan's most representative fruits, which can be eaten fresh, used in cooking, and processed into various foods. Pineapple is available all year round in Taiwan, as it is a tropical fruit, but the best quality is produced during the peak season of spring and summer (March-July).
Pineapple is a long-term crop with a long cultivation period, and the current used cultivation system is to harvest the fruit twice in a three-year cycle. Most farmland has soil problems due to long-term continuous cropping, but reasonable fertilization can reduce fertilizer costs and ensure the sustainable use of soil.
Reasonable and moderate fertilization can promote the growth of pineapple plants, increase yield, promote early sprouting, and improve the yield in the following year. Nitrogen (N) and potassium (K) fertilizers have the greatest impact on the yield and quality of pineapple. If pineapple plants receive excessive nitrogen (N) fertilizer during the growth period or encounter low temperatures, the roots may absorb insufficient phosphorus (P) then causes leaves to turn red. During the flowering stage, excessive nitrogen (N) fertilizer, excessive temperature differences, and boron (B) deficiency may lead to fruit pedicel fracture, affecting the normal development of the fruit. During the fruit enlargement stage, excessive nitrogen (N) fertilizer application, low temperatures, and a lack of water cause calcium (Ca) deficiency may lead to fruit cracking.
Farmers use excessive nitrogen (N) fertilizer and overlook the importance of potassium (K) fertilizer. Nitrogen (N) fertilizer application can be reduced during the growth stages, while potassium (K) fertilizer should be applied more to improve fruit quality. Therefore, it is necessary to pay attention to the supplementation of different nutrients during the different stages of pineapple and avoid excessive use. In case of nutrient absorption barriers caused by climate and soil conditions, foliar fertilization can be used more to supplement the deficiency. Pineapple is a CAM plant. In the daytime, stomata close to reduce water loss, while at night, they open for carbon fixation. Therefore, foliar fertilization (liquid fertilization) is more effective when applied in the evening.
During the pineapple reproductive growth stage, appropriate water supplementation can promote fruit growth. However, the central and southern regions of Taiwan might face water shortage crises during winter. Although pineapple is a drought-resistant crop, severe water shortage can affect fruit development and quality. To avoid the growth barriers caused by winter drought, we recommend using Ca Strong 801, which is a special formula that significantly enhances crop tolerance to the environment, has good water retention and drought resistance capabilities, and is combined with high calcium (Ca) content to reduce fruit cracking happen. It also contains the important trace element – boron (B), which is necessary for pineapple growth and differentiation. When plants lack of boron (B), tissue browning may occur near the central of the fruit. When the deficiency is severe, the fruit skin may crack, and the fruit pedicel may easily break. Therefore, using appropriate amount of boron (B) can prevent the above symptoms occurring.
