The on farm demonstration was conducted in farmers fields in five locations of Khammam District of Central Telangana Zone during three kharif seasons of 2013, 2014 and 2015 by District Agricultural Advisory and Transfer of Technology Centre, Khammam belongs to Professor Jayashankar Telangana State Agricultural University, Hyderabad in order to find out the suitable pre and post emergence of herbicides in direct sowing rice crop viz, T1- Butachlor@ 1.5kg/ha fb Bispyribac sodium 250 ml/ha, T2-Pendimethalin @ 2.5 Lt/ha fb Bispyribac sodium 250 ml/ha T3-Pyrazosulfuron ethyl 200 gr/ha +Bispyribac sodium 250 ml/ha, T4-Oxadiargyl 100 gr/ha + Bispyribac sodium 250 ml/ha, T5-FarmersPractice (Delayed and Ignored Practices). The experimental results revealed that the significant influence on both growth and yield attributes as well as on economics of the direct seeding rice. The maximum growth in terms of plant height (98.6 cm), no of effective tillers (308), and no of hills per square meter (32) as well as the yield (5964 kg/ha), no of panicles per square meter (300), and length of the panicle (24.6 cm), Harvest Index (42.6 %) were higher with the application of Pyrazosulfuron ethyl 200 gr/ha +Bispyribac sodium 250 ml/ha than other treatments. Similarly maximum monitory net returns (58,373/-) and weed control efficiency (84.4%) were recorded with the application of Pyrazosulfuron ethyl 200 gr/ha +Bispyribac sodium 250 ml/ha, however it was on par with application of Oxadiargyl 100 gr/ha + Bispyribac sodium 250 ml/ha. The lowest growth and yield attributes were observed in Farmers Practice.
