MalikBashir Ahmed 3200113The study on weed control in lentil was conducted at the National Agricultural Research Centre, Islamabad during Rabi, 1987 and 1988. The performance of selected Pre-emergence herbicides; Oxadiazon, Pendimethalin, Isoproturon and Methabenzthiazuron and Post-emergence herbicides; Fomesafen, Fluazifopbutyl and Methabenzthiazuron alone and in combinations were evaluated to know their broad spectrum performance, if any; against a lentil variety Precoz. Hand weeded and weedy plots were kept for comparison of yield and economic gains. Most of the herbicides applied and hand weeded plots controlled the weeds density per unit area by 19 and 100% and significantly increased grain yield by 9 to 113% (440 kg/ha to 936 kg/ha). Among the pre-emergence weedicides, Oxadiazon gave the highest grain yield of 764 kg/ha and earned net return/per rupee investment of Rs. 1:2.15, while post-emergence treatment hand-free check (twice) gave the highest yield of 936 kg/ha or 113% increase over control (440 kg/ha) and earned net return of Rs. 1:2.86, whereas mixture of Fluzifopbuty+ Fomesafen at given rates of 0.50+0.13 a.i/ha and 0.75+0.13 a.i/ha produced 635 and 849 kg/ha respectively by controlling grasses and broad-leaved weeds to the extent of 69/100 and 75/94% and earned net returns of Rs. 1:2.14 and 1: 3.22 respectively.]]>Anonymous,19991999Ali, A., M.
