Pineapple is a good source of Vitamin A,B,C and also calcium, magnesium, potassium and iron. It is also a good source of bromelin, a digestive enzyme. It is consumed fresh or in the form of juice, jam, squash and syrup.... It takes knowledge, time, and plenty of patience to grow and harvest a pineapple crop. Most of the process cannot be automated, and must be done by hand. To propagate a pineapple is to use the green, leafy top of the pineapple, called the crown, as planting material. Each crown is planted by hand. Plantation workers use a spade-shaped tool to pierce the plastic mulch, dig a shallow hole, then place the crown in the hole, right side up. A skilled planter can plant more than 10,000 pineapple crowns a day—nearly half an acre.
