Abstract: A field experiment was conducted on medium black soil during kharif 2016 & 2017 at Agricultural Research Station, Gangavathi to study the effect on weed growth, yield and yield attributes of direct dry seeded rice. The results revealed that among the different drip irrigation systems the surface drip irrigation proved best over subsurface drip irrigation systemand among herbicidal treatments, pretilachlor @1.0 kg a.i/ha followed by one hand weeding @ 45 DAS significantly reduced the weed density (5.33/m2), dry weight of weeds (5.51 g/m2), weed index (20.17%) and the hand weeding thrice @ 20, 40 and 60 DAS recorded higher weed control efficiency (65.62%) than other treatments at harvest. This was followed by pretilachlor @1.0 kg a.i/ha followed by one hand weeding @ 45 DAS which recorded WCE of (51.05%). Among the treatments, hand weeding thrice at 20, 40 and 60 DAS recorded higher grain yield (5365.88 kg ha-1) which was followed by pretilachlor @1.0 kg a.i/ha followed by one hand weeding @ 45 DAS with a grain yield of 4273.08 kg ha-1 which was significantly superior to other treatments
