Crop Weed Competition in Sugarcane-A Review

Sugarcane (Saccharum officinarum L.) is the most adaptable plant under sub-tropical and tropical conditions. Among the C₄ group of plants, sugarcane is one of the most efficient crops. Converting the efficiency of solar radiation into photosynthates is relatively higher in sugarcane than any other crops evolved. But there is a wide yield gap between the potential and actual yield. Weeds are the important major threat in a yield reduction of sugarcane crop. Hence knowledge about weed flora, a critical period of crop weed competition, the competition of weeds, the effect of weed on crop growth is helpful in deciding the method of weed management in particular crop. Reviewing these parameters is helpful, and it is carried out in this paper.
