Why sesame crop rotation and changing crops can achieve comprehensive yield increase

(Agricultural Wealth Network) First, the secretions from sesame roots can promote the reproduction of microorganisms in the soil, accelerate the decomposition of organic matter in the soil, improve soil fertility, and have the effect of usefully nourishing the land, thereby increasing the yield of the following crop. Second, it significantly increases sesame yield per unit area. In continuous cropping land, the average seedling death rate at the initial flowering stage of sesame was 41.1%, while there was no seedling death in non-continuous cropping land; at the maturity stage, the average disease incidence rate was 79.2% in continuous cropping land and 1.34% in non-continuous cropping land. The yield of non-continuous cropping was 29% higher than that of one year of continuous cropping, and 80% higher than that of two years of continuous cropping. In production, “planting in two of four years” (that is, leaving a 2-year gap without planting sesame in between) is preferable, and paddy-upland rotation is even better.
