The experiment was conducted to evaluate the effect of herbicide, plastic mulch as well as solarization on growth and yield parameters of brinjal hybrid ‘BH-6747’economics of weed management was also evaluated during kharif season of 2011-2012 at Vegetable Research Farm, Department of Vegetable Science, Punjab Agricultural University, Ludhiana (Punjab). Pendimethalin, oxyflourfen and trifluralin herbicides were used with two different doses and respectively with combination of hoeing and gramaxone used at 45 days interval after transplanting. It is concluded that black polyethene mulch improves the yield and its parametres as a result of which yield was improved where it recorded a yield potential of 510.55q/ha as compared to 341.06q/ha in unweeded check. Among chemical treatments maximum yield was obtained with oxyfluorfen (pre-emergence) @ 0.15 kg a.i/ha + hoeing (45 DAT) (T7) which recorded a yield potential of 489.22q/ha. It is thus concluded from the present investigation that oxyfluorfen (pre-emergence) @ 0.15 kg a.i/ha + hoeing (45 DAT) is beneficial for weed management in brinjal and also it improves the cost-benefit ratio. No phyto-toxicty effect of oxyflourfen was observed on brinjal plants hence this treatment was recorded better than rest of the treatments. It is also conclude that oxyflourfen @ 0.175 kg a.i/ha can be used in the nursery of brinjal without effect on germination percentage of seedlings.
