For the proper establishment of the corn plant, it should be noted that the seeds germinate and appear uniformly. It is clear that seed shape and size (seed grading) has nothing to do with germination, seed vigor or yield.
Almost all 400 thousand hectares of agricultural land under corn cultivation in Iran is irrigated. Therefore, improving irrigation management can have a significant impact on the quantity and quality of water, which is known as the most important resource of the country. Correct management of irrigation in corn fields can bring factors such as economic production, saving water resources and maintaining or increasing water quality. For this purpose, it is necessary to use estimation of evaporation and transpiration of corn and accurate measurement of water in the soil profile to determine the time and amount of irrigation.
Packaged silage can have variable nutrients depending on what kind of edible material it is made from, but what is used the most in Iran is corn silage.
The crop provides livestock producers with a high-yielding, relatively consistent source of forage and the animals with a highly digestible and palatable feed. Corn silage produces more energy per acre than any other crop grown in Pennsylvania.
Corn silage is a popular forage for ruminant animals because it is high in energy and digestibility and is easily adapted to mechanization from the stand-crop to time of feeding.
