An experiment was designed to investigate the feasibility of using extract of sorghum as a natural weed control approach in comparison with hand weeding and herbicides for wheat crop. The experiment was conducted at Agricultural University Research Farm of NWFP Agricultural University, Peshawar during 1999-2000. Ten treatments were studied in the experiment including check, hand wedding, herbicides Assert and Diazon and 20, 30 and 40 kg sorghum extract ha-1 applied once and twice. Mature sorghum herbage was used for preparing water extract in 1: 20 ratio i.e. 1 kg sorghum herbage soaked in 20 L of water. Sorghum extracts of 20, 30 and 40 kg ha-1 were applied twice, 55 days after sowing and 85 days after sowing. Hand weeding was carried out as required while no weed control was done in check plots. All the weeding control treatments significantly affected seed filling duration, weeds weight, weeds number and grain yield. Sorghum extract also reduced weeds number and weeds weight. Plots sprayed with Diazon herbicides application resulted maximum mean tiller growth rate (0.05 g day-1). Diazon reduced weds mass and weeds number. Sorghum extract at the rate of 30 kg ha-1 twice increased fresh (13.25 g) and dry (6.28 g) and grain yield (4318 kg ha-1) as compared to check plots |
