Abstract:

A field experiment was carried out to assess the weed management studies in wheat-vegetable intercropping system and planting patterns at the Research Farm, Faculty of Agriculture, Gomal University D. I. Khan, Pakistan during winter season 2009-2010. Randomized complete block with sixteen treatments replicated thrice. Wheat variety “Sahar” was planted at seeding rate of 125 kg ha-1. Experiment was conducted during winter 2009 and recommended doses of farm yard manure and NPK were applied. Statistical analysis of the data revealed that highly significant (P=0.01) differences were observed for biological yield, grain yield, weeds density, fresh and dry weed biomass. Among the planting geometries, single row sole wheat depicted maximum biological (13.93 t ha-1) as well as grain yield (5.173 t ha-1). The highest reduction in weed density was recorded in treatment having 4 row strip wheat + 2 row onion. Similarly dry weed biomass was also highly significantly (P=0.01) reduced by 4 row strip sole wheat + 2 row onion. The instant results suggest that intercropping in wheat could be used as a viable weed management approach.
