Abstract:
The potato (Solanum tuberosum L.) is a useful food and cash crop ranked third in the list as world’s most popular food hence widely grown over the world including Pakistan. In China and India about one third of the world’s potatoes produced. Potatoes are spread over a large area of Pakistan with the production of 4.1 million tons. Weeds are undesired species that stop growth and yield of cultivated crops. Weeds interfere with crops because of their direct competition for sunlight, water, nutrients and space. Competition of weed is most severe and can decrease production of potato at initial stage of growth. Weeds decrease the effectiveness of agricultural tool and excellence of fertile lands, reduce the germination capability of crops seed due to phytotoxins. Current review comprehend all available literature of weeds present in potato crop.All over the world quadrate method was used to study the weeds of potato at different 12 countries around the globe. A total of 160 weed species belonging to 46 genera and 16 families were reported. Anagallis arvensis L., Poa annua L., Lathyrus aphaca L., Phalaris minor Retz, Galinsoga parviflora Cav.,Cirsium arvense L., Cyperus rotundus L., Acalypha indica, Amaranthus spinosus L. andImperata cylindrica L. were dominantly reported weeds. In Pakistan 14 different surveys were conducted to enlist the weedy flora grown in potato crop by using quadrate method (1m2 x 1m2). These surveys reported 75 different weed species and Poaceae and Amaranthaceae as dominant families. Punjab is leading province of Pakistan for production of potato but there is no proper weed survey conducted in this area. This study is conducted to explore the weed flora of such area which were not under the phytosociological discussion before.
