Abstract:
The experiment was conducted at Sri Durga Ji Post Graduate college, Chandeshwar, Azamgarh, ( U.P.) during rainy and winter seasons of 2019-20 and 2020-21.To study the Influenced by Herbicidal weed control methods in yield of blackgram mustard cropping system The experiment was laid out in a RBD with 16 treatments i.e. Imazethapyr 50 g/ha PRE (T1), Imazethapyr 70 g/ha PRE (T2), Imazethapyr 80 g/ha PRE (T3), Imazethapyr 50 g/ha POE (T4), Imazethapyr 70 g/ha POE (T5), Imazethapyr 80 g/ha POE (T6), Imazethapyr. + Imazamox (RM) 50 g/ha PRE (T7), Imazethapyr.+ Imazamox (RM) 70 g/ha PRE (T8), Imazethapyr.+Imazamox (RM) 80 g/ha PRE (T9), Imazethapyr.+Imazamox (RM) 50 g/ha POE (T10), Imazethapyr.+Imazamox (RM) 70 g/ha POE (T11), Imazethapyr.+Imazamox (RM) 80 g/ha POE (T12), Pendimethalin 1000 g/ha PRE (T13), Imazethapyr + Pendimethalin (RM)1000 g/ha PRE (T14), Hoeing twice (T15) each performed at 20 and 40 DAS and weedy check (T16) replicated thrice. Blackgram var. T9 and mustard var. Shivani was sown at 30 cm using 30 and 8 kg seed/ha, with RDF 20:40:20 and 80:40:20 k g/ha, respectively. Application of Imazethapyr.+ Imazamox (RM) 80 g/ha POE (T12) also recorded higher yield attributes and grain and straw yield compared to rest of weed treatments.
