« Crop info 


Juicy fruits, substances for cosmetics, cloth and industry Bromeliads, including pineapple, are grown for their leaf fibres, and many more are grown as ornamentals. Ananas comosus (L) Merr. is the only species grown commercially for its fruit.

Pineapple is cultivated for fruit, used fresh, canned, frozen, in desserts and other types of fruit dishes or made into juices, syrups, or candied. A mixture of several proteases, bromelain is used in meat tenderizers, in chill-proofing beer, manufacturing precooked cereals, in certain cosmetics, and in preparations to treat edema and inflammation. Ethyl acrylate, found in fruits, is used in creams, detergents, food, lotions, perfumes, and soaps.
Ecology and planting
Pineapple can be grown in a wide variety of soil types as well as under a wide range of rainfall, from 600 mm to over 3.500 mm annually. The optimum temperature is close to 30°C day and 20°C night. Major areas of commercial cultivation are found between 30°N and S latitudes. Time from planting to harvest depends primarily on the mass of the propagule (different for crowns, slips and suckers) generally 14-24 months. Plant density from 44,444 to 58,700 plants per ha.
Mycorrhiza & Bio-fertilizers
The inoculum can be introduced by dipping the cuttings into the gel formulation of inocula before planting or in a nursery by mixing dry inoculum formulation in the planting substrate. The expected effect of mycorrhiza combined with biofertilizers in the field is a larger number of fruits by 15% and early onset of fruiting. Treated plants should be more resistant to soil borne diseases; prolonged survival and full fruiting can be expected. Mycorrhiza was also reported to increase production of sugars in fruits. Reduction of fertilizer application within the first season by 50% due to application of mycorrhiza and biofertilizer products.
