Weed in sugarcane Fields

บทคัดย่อ

One of the most important aspects of successful weed control is a knowledge of weed species and the reservoir of viable weed seeds present in the soil. Sugarcane in Thailand is cultivated in the following four widely dispersed regions: the Central, Northeastern, Western and Eastern, and weed species common throughout these regions were surveyed first. The floristic composition of weed populations is known to be influenced not only by geographical factors but also by changes in environmental conditions and cultivation practices. Therefore, seasonal and annual shifts in weed populations were also determined.
Another important factor which regulates actual weed populations is the weed reservoir in the surface layer of soil was also estimated.
