Abstract:

Field investigation on evaluation of pre and post emergent herbicides on yield parameters and yield of aerobic rice was conducted during kharif 2014 at agricultural college Farm, Rajendranagar, Hyderabad. The experiment consisted of combination of pre and post emergence herbicides alone, in combination with hand weeding and hand weedings at 20, 40 & 60 DAS and un-weeded check. The results revealed hand weeding at 20, 40 and 60 DAS recorded significantly higher growth and yield components viz., no. of panicles/m2, test weight, panicle length, panicle weight, grain yield, straw yield and higher weed control efficiency which was at par with Pretilachlor 0.75 kg ai ha-1 as PE fb Azimsulfuron 35g.ai ha-1 + Cyhalofop butyl 75 g. ai ha-1 as PoE 15-20 DAS followed by hand weeding at 50 DAS under both the seeding methods.

Keywords: Aerobic rice, Yield parameters and yield.
