Contact SupplierSweet corn is a particular maize species which differ genetically from the field maize. Its kernels are tender, delicious and eaten as a vegetable in many cuisines worldwide. In contrast to the traditional field corn, sweet corn crops are harvested while their corn-ears have just attained the milky stage. The cob either used immediately or frozen for later use since its sugar content turns quickly into starch.
Corn is native to the Central Americas which then introduced to the rest of the world through Spanish explorers. Sweetcorn differs genetically from the field maize by mutation at the sugary (su) locus.
The crop has achieved a major success as one of the important commercial cash crops in many tropical and semi-tropical countries, incuding the USA. Scientific name:Â Zea mays var. saccharata.
Corn grows to about 7-10 feet in height. It grows quickly under sunny, fertile, and well-drained soil supplanted with good moisture conditions. Each plant bears about 2-6, long husked "ears" filled with rows of tooth-like seeds arranged around a central woody core (cob). Optimum pollination is essential for full kernel development.
Several different sweet corn cultivars with variations in their sweetness, color, and maturation are grown keeping in mind of local and regional demands. Most farmers opt for crops that attribute superior eating and keeping quality and high yields. Examples include Standard (su), Sugary Extender (se), Supersweet (sh2), Synergistic (sy), and Augmented Supersweet. Depending on the cultivar type, the crop can be ready for harvesting in 65-90 days. Harvesting is done when the free end (silk end) of the ear is full, its silk has turned brown, and its kernels are firm but in the milky stage. Often, farmers check the kernels by pricking them with their thumbnail to ascertain harvest timing.
Baby corns are very young, miniature ears harvested when their kernels are still at the incipient stage. Its central core is sweet and tender enough to be eaten raw. Baby corns measure about 3-5 inches in length and weigh about 20-50 g each.
