Jackfruit or jack (Artocarpus heterophyllus), also known as jacquier, kathal, langka, nangka, khanun, makmi, banun, nongko, kapiak and peignai, is a plant which probably originated from the Western Ghats in India. It has become naturalized in many tropical countries, mostly in Southeast Asia where it is considered a major fruit. Where food is scarce, it is utilized as a staple. This fruit crop is adapted to warm and humid climates below 1000 masl, but it can thrive up to 1600 meters. It has poor cold, drought and flooding tolerance but has moderate tolerance to wind and salinity. It favors an annual rainfall of 1500 mm or more without pronounced dry season. It grows on various types of soil but prefers deep, well-drained, alluvial, sandy or clay loam soils with pH range of 6.0 to 7.5. This
