Abstract:
An experiment to study the impact of integrated weed management strategies in wheat crop was conducted at the Agronomic Research Area of the Faculty of Agriculture, Gomal University, D. 1. Khan, Pakistan. during 2001-02. Four post-emergence herbicides in comparison with kasola hoeing, weed free for full season and weedy check were evaluated. 2,4-D Ester and Buctril M40EC @1.25 L ha-1 each were applied alone and in combination with Puma Super 75EW @ L ha-1. One, two and three hoeings with kasola were clone after first, second and third irrigation, respectively. The data revealed that the application of herbicides and Kasola hoeings significantly affected the fresh and dry weed biomass (g in -2), number of tillers m -2, spike length (cm), number of spikelets spike-`, number of grains spike-1 and grain yield (t ha-1). Weed free crop for full season produced the highest grain yield (7.08 t ha-1). Among herbicides, the mixture of BuctrilM40EC and Puma Super 75EW produced the maximum grain yield (5.60 t ha-1), whereas three hoeings with kasola gave the highest grain yield (5.21 t ha-1) among the kascla hoed treatments.
