Interplanting ryegrass with tobacco at specific times can improve the quality of tobacco leaves. Early interplanting between certain growth stages enhances physical characteristics and chemical balance in the leaves. This results in reduced nicotine and chlorine levels, increased potassium content, and improved sugar levels. While the yield of tobacco leaves may slightly decrease, the quality and value of the crop increase significantly. The best quality and highest yield are achieved when ryegrass is interplanted with tobacco after 30 days of transplanting.
