What is the practice of planting grain sorghum into the stubble of a wheat crop immediately after harvest called?

The practice of planting grain sorghum into the stubble of a wheat crop immediately after harvest is known as double cropping. This agricultural method allows farmers to maximize the use of their land and resources by growing two different crops in a single year on the same field. After the wheat is harvested, the remaining stubble provides a structure for the sorghum to be planted, which can lead to better soil retention, reduced erosion, and efficient use of nutrients.

Double cropping not only enhances productivity but also optimizes the growing season, allowing farmers to take advantage of climatic conditions for successive crops. This technique can result in increased overall yields, making it a valuable strategy in certain agricultural systems. The other options involve different agricultural strategies, such as intercropping, where two crops are grown simultaneously in the same field, and fallowing, which refers to leaving a field unplanted to restore its fertility.
