Tillage and weed management practices affect physico-chemical characteristics of soils. Therefore, a field study was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya, during rabiseason 2017-18 with two tillage practices i.e., conventional tillage (CT), Zero tillage (ZT) and three weed management practices i.e., Clodinafop+ Metsulfuron (60+4 g ha-1) RM, Clodinafop+ Metsulfuron (60+4 g ha-1) RM fb 1 hand weeding and One hand weeding (45DAS). Effect of these treatments was observed on soil pH, electrical conductivity (EC), bulk density, soil organic carbon content (SOC), and Av. N, P, K and Zn. Among tillage practices, the mean highest SOC was found under ZT+R (3.7 g kg-1) followed by ZT (3.5 g kg-1 ) and lowest under CT (3.3 g kg-1) for soil and weed management was found under Clodinafop + metsulfuron @ 60+4 g ha-1 (30 DAS) fb 1 hand weeding (45 DAS) 3.6 (g kg-1) followed by Clodinafop+ metsulfuron@ 60 +4 g ha-1 (30 DAS) 3.6 (g kg-1) Mean highest Av. N, P, K and Zn (kg ha-1) was observed under ZT+R (170.33), (16.64) , (282.24) and (7.02) and the lowest under CT 149.67(kg ha-1), (14.62) (kg ha-1), (248.00) (kg ha-1) and (6.17) ppm for soil and weed management was found under Clodinafop + metsulfuron @ 60+4 g ha-1 (30 DAS) fb 1 hand weeding (45 DAS) 162.60 (kg ha-1), 15.89 (kg ha-1), 269.43 (kg ha-1) and 6.70ppm. Effect of tillage and weed management practices on soil pH, EC and bulk density was not significant in the soils.
