Wheat is a crop with poor self-tolerance, which is why the choice of predecessor is an important element of cultivation technology. The most suitable precursors are crops like (peas, beans, lentils, etc.), followed by trench crops (corn, sunflower, etc.); the most unsuitable are other winter crops (barley, triticale, rye) and perennial grasses.

Sunflower is an annual crop. The choice of growing field should be based on the requirements of the sunflower crop to the predecessor. As sunflower is attacked by a number of diseases that are spread by plant debris and soil (sclerotinia, foma, fomopsis, alternaria), it should not be sown in the same field for at least 5 years.

Corn is a thermophilic plant, whose high temperature requirements are manifested during the sowing period. Germination takes place at a soil temperature of 8-10 ° C, and at lower temperatures, the seeds can rot.
