Abstract: A field experiment was conducted at Highland Agricultural Research and Extension Centre, Kukumseri (Himachal Pradesh) during 2010 and 2011 to develop weed management practice for tomato (Lycopersicon esculentum Mill) under dry temperate conditions of western Himalayas. Application of pendimethalin @1.5 kg ai ha-1 and fluchloralin @ 1.0 kg ai ha-1 being equally effective gave maximum control of weed by lowering the weed density, weed dry matter accumulation and thereby recording higher weed control efficiency of 97.5 and 98.5%, respectively. However treatment two hand weedings at 30 and 60 DAT was also statistically at par with these above treatments giving weed control efficiency of 97.8%.These three treatments were also statistically at par with each other for average fruit weight, number of fruits per plant with corresponding fruit yield of 21.80, 21.08 and 23.23 t ha-1, respectively .The highest net return of INR 3, 82,196 ha-1 and B: C ratio of 4.63 was obtained with treatment two hand weeding(30 and 60 DAT) which was followed by application of pendimethalin @1.5 kg ai ha-1(net return INR 3, 75,153 and B:C ratio 5.01).
