The on farm trial (OFT) was conducted to find out the cost-effective weed management practices for pigeonpea during Kharif season of 2021-22 with four replication one at in crop cafeteria (Technical Park) of Krishi Vigyan Kendra and remaining three conducted at farmers’ field of village Bharauli block Sohaon, district Ballia Uttar Pradesh. Seven treatments were viz., T1-weedy check, T2-Hand weeding, T3-Pendimethalin @ 750g a.i. ha-1 as PE, T4 -Imazethapyr @ 100g a.i. ha-1 at 30 DAS, T5 - quizalofop-ethyl @ 50g. a.i. ha-1 at 30 DAS , T6 - Pendimethalin @ 750g a.i. ha-1 as PE fb Imazethapyr @ 100 g a.i.ha-1 at 30 DAS [POE], T7 - Pendimethalin @ 750g a.i. ha-1 as PE fb quizalofop-ethyl @ 50g. a.i. ha-1 at 30 DAS [POE]. The pre-emergent herbicide i.e., Pendimethalin was sprayed within 24 hr of sowing and post emergence herbicides i.e., Imazethapyr and Quizalofop-ethyl were sprayed 30 DAS between the crop rows (directed sprays). Among all the treatments, pre-emergence application of Pendimethalin followed by Imazethapyr at 30 days after sowing (DAS) was significantly recorded lowest weed growth and weed dry weight with WCE of 82.64 per cent at 60 DAS and 76.80 percent at 90 DAS, respectively.
