The protein from maize is further enhanced by protein contributions from beans and pumpkin seeds, while pumpkin flesh provides large amounts of vitamin A; with the Three Sisters, farmers harvest about the same amount of energy as from maize monoculture, but get more protein yield from the inter-planted bean and pumpkin. Mt.
The modern combine harvester, also called a combine, is a machine designed to harvest a variety of cultivated seeds. Combine harvesters are one of the most economically important labour-saving inventions, significantly reducing the fraction of the population engaged in agriculture. [1]
In Africa, post-harvest losses of maize from harvest to market sale are believed to amount to around 10-20%. Approximately 40% of these losses occur during storage at the farm and market, 30% during processing (drying, threshing, and winnowing), 20% in transport from the field to the homestead/farm, and the remaining 10% during transport to market.
Maize is a tall annual grass with a single stem, ranging in height from 1.2 m (4 ft) to 4 m (13 ft). [31] The long narrow leaves arise from the nodes or joints, alternately on opposite sides on the stalk. [31] Maize is monoecious, with separate male and female flowers on the same plant. [31]
Maize, beans, and pumpkins were dried, packed into rawhide bags, and stored in bell-shaped underground storage pits. The Pawnee followed the harvest with a month of celebrations and in early December departed their villages again for a winter hunt, their stored agricultural products hidden beneath in underground pits.
Maize reached the Southwest via an unknown route from Mexico. Its diffusion was relatively rapid. One theory is that the maize cultivation was carried northward from central Mexico by migrating farmers, most likely speakers of a Uto-Aztecan language. Another theory, more accepted among scholars, is that maize was diffused northward from group ...
Maize and whole crop silage are cut directly by the header, using reciprocating knives, disc mowers or large saw-like blades. Kernel processors (KP), modules consisting of two mill rolls with teeth pressed together by powerful springs, are frequently used when harvesting cereal crops like corn and sorghum to crack the kernels of these plant heads.
In batch drying methods, certain amount of grain is placed first, usually 2 to 4 inches, the batch is dried and cooled later, then drying is stopped and batch is removed. The batch dryers are usually operating under this sequence and repeating this sequence for several times. The bin-batch drying methods employ a full perforated floor as the dryer.
