Effect of some weed control treatments on potato (Solanum tuberosum)

Potato belongs to family solanaceae; as one of the most important vegetable crops for local consumption processing and exportation in Egypt. It is an annual herbaceous plant with fleshy tuber that arises underground.Nowadays a great part of potato crop is directed to chips production to supply the Egyptian and foreign markets.Weeds in Potato fields not only compete potato for growth factors but also act as hosts of insects and fungal diseases that in turn infest potato plants. Weed growth reduce the yield of potato tuber by 50 % of yield. Evaluation of herbicides in field crop depends not only on the efficiency of the herbicide to control weeds but also includes the obtaining of crop growth and high productivity and quality of yield. Thus the objectives of this study aimed to increase potato yield production.
