Abstract: The study on weed control in chickpea was conducted at the National Agricultural Research Centre, Islamabad to evaluate the performance of selected Pre-emergence herbicides; ronstar, stomp, tolkin and tribunil and post-emergence herbicides; flex, fusilade and tribunil. Treatment-wise per hectare cost incurred on pre-emergence herbicides was Rs.540, Rs.247, Rs. 270 and Rs.369, whereas on post-emergence herbicides,it was Rs.36, Rs. 225, Rs.261, Rs.374, Rs. 369 and Rs.1050. These herbicides were applied alone and in combinations to study broad spectrum performance, if any. Two checks, hand weeded and weedy plots were kept for comparison of yield and economic gains. Chickpea variety was CM-72. Almost all the herbicides treated and hand weeded plots controlled the weeds density per unit area by 21 to 141% and significantly increased the grain yield by 14 to 141% or 332 kg ha–1 to 735 kg ha–1. Amongst pre-emergence herbicides, ronstar and Stomp gave the highest net return/per rupee investment of Rs.1:3.76 and Rs.1:2.74 respectively, followed by tribunil and tolkan to the tune of Rs.1: 2.70, while the post-emergence herbicide Fusilade applied at 0.75 and 0.50 kg a.i. ha–1 gave net return of Rs.2.36 and 2.10. post-emergence herbicide flex followed these treatments and earned net return of Rs.1.99. Low return from flex alone or when mixed with fusilade are likely due to phytotoxicity caused by flex being non-selective against broadleaf plants. Hand weeding though gave quite reasonable yield of 776 kg ha–1, yet its return were lowest because of low labor efficiency at high cost of prevailing daily wages.
