Two pre- emergence herbicides (Stomp 330 EC, Dual gold 960 EC) and two post-emergence herbicides (Puma super 75 EW, Topik 15 WP) were applied including control treatments (weed free and weedy check). The results of this study showed that maximum seed yield of 401.0 kg ha -1 was obtained from hand hoeing treatment followed by post emergence herbicide Puma super 75 EW applied @ 1.2 lit ha -1 with 353.2 kg ha -1 seed yield against 212.2 kg ha -1 from weedy check treatment. The highest yield in top scoring treatment is due to higher number of branches plant -1 , number of pods plant -1 , number of grains pod -1 and individual grain weight. So from the results of this study it is concluded that hand hoeing can be recommended only for small land holders with sufficient available family labour while, Puma super 75 EW @ 1.2 lit ha -1 is recommended for control of chickpea weeds under semi arid rainfed conditions. Key words: Chemical control, gram, mechanical control, post and pre-emergence herbicides. I NTRODUCTI ON Chickpea ( Cicer arietinum L.) is an ancient crop that has been grown in India, the Middle East and parts of Africa for many years and is an important edible legume pulse of the family Fabaceae, subfamily Faboideae. In Pakistan, chickpea is cultivated on an area of 1094 thousands hectares with production of 760 thousand tons (Anonymous, 2009). 1 Department of Agronomy, Pir Mehr Ali Shah Arid Agriculture University Rawalpindi, Pakistan, E-mail: drmatarar@gmail.com
