Abstract
Wheat (Triticum aestivum L.) is of prime importance being staple food of the masses
of Pakistan. Weed infestation in wheat not only reduce the yield but also affects the
efficiency of other production factors. Allelopathy is sustainable and ecofriendly
method for the management of weeds and diseases. A field trail was carried out to assess
the allelopathic potential of mulberry and sorghum water extracts against invasive
winter weeds like Phalaris minor. Retz, Chenopodium album L., Avena fatua L. and
Convolvulus arvensis L. in wheat at Agronomic Research Farm, University of
Agriculture, Faisalabad. Experiment was laid out in randomized complete block design
(RCBD) with four replications. All the treatment application showed better weed
management and enhanced final yield of the crop. Application of sorghum water extract
(SWE) at the rate of 18 L ha-1 and mulberry water extract (MWE) at the rate of 18 L ha-
1 indicated better weed management (51-55%) and improved grain yield (28%) as
compared to control. SWE at the rate of 27 L ha-1 and MWE at the rate of 9 L ha-1 in
combined application also showed better weed management and improved the grain
yield while Atlatis (Standard herbicide) had 66-68% weed control and 32% increase in
final yield but it was not found economical. Combined application of SWE at the rate
of 18 L ha-1 and MWE at the rate of 18 L ha-1 was found best combination with
maximum net return while hand weeding and herbicide application were extravagant
because of high cost and low net return.
