Abstract
Abstract Field investigations on a moderately fertile silty clay loam soil in the northwestern Himalayas revealed that the weed flora in wheat crops in this zone comprised mainly of three grassy weeds: Phalaris minor Retz., Avena fatua L. and Lolium temu‐lentum L. Cultural manipulations such as closer spaced rows, i.e. 15 cm spacing between rows, and/or cross row sowing in combination with the application of isoproturon at 0.50 kg a.i./ha applied 2 weeks after sowing significantly reduced the density of Phalaris minor and Avena fatua weeds. The dry weight of these grassy weed species was significantly lowered with the application of isoproturon irrespective of its rate and time of application. Isoproturon application at a rate of 1 kg a.i./ha or 0.50 kg a.i./ha in combination with cross row sowing, normal row spacing of 22.5 cm or closer spaced rows of 15 cm reduced the weed competition and resulted in positive advantages in yield attributes and increased the grain yield of wheat.
