The cultivation of pineapples requires warm climates with temperatures of 24-30 °C. A rainfall rate of 1000 -1500 mm per year promotes the yield of the pineapple. However, stagnant moisture must not build up in the soil. The plant grows reliably in sandy, peaty soil, whereby a pH below 5,5 is important. Since the plant requires relatively little water, drip irrigation is sufficient. After harvesting, it is usual to grow further fruits on the side shoots. The pineapple grows on a stem. At first, purple-colored flowers are formed that grow together to form a fruit, which only really begins to ripen when the buds have faded. It takes 16 to 23 months for pineapples to grow and the average production is 30-50 tons per ha, with good management it can reach up to 60-75 tons per ha. Pineapple seedlings can be transplanted from spring to autumn; in warm winter and well-irrigated areas, it can be planted at any time of the year.
The main nutritional demands of the pineapple crop concern potassium and nitrogen, since the yield depends on these two elements. The need for phosphorus is low, as it is primarily required during the flowering stage. However, the supply of calcium and microelements such as zinc and boron is important to increase quality and post-harvest life.
The whole life cycle lasts around 16 to 23 months, which is quite long. We can recommend our compound fertilizer NovaTec® or DuraTec® as a base application, which can increase the nutrient efficiency and save labor costs.
During the fast vegetative stage, which needs a lot more nutrients, we can recommend NovaTec® Solub for irrigation systems.
From the seedling to the slow vegetative stage, root growth is important. We can dip seedlings into Basfoliar® Kelp SL solution, then spray or irrigate Basfoliar® Kelp SL and Basfoliar® CaBMg SL after transplanting.
During the flowering stage, Basfoliar® Boro SL and Basfoliar® Zn Flo are good for pollination.
During the fruit growing stage, Basfoliar® CaBMg SL can be applied to increase fruit weight and reduce the black heart disease infection rate after the harvest. Micronutrients from the Fetrilon® Combi line can boost the plant growth. Basfoliar® Avant Natur SL can be used during the whole stage, especially in abiotic stress situations.
