Abstract

A field study was conducted during the two successive years of Rabi, 2020–21, 2021–22 and Kharif, 2020–21, 2021–22 at the research farm of Lovely Professional University, Jalandhar, Punjab (India) in a RBD (randomized block design) with eight weed-controlling treatments with three replications. In wheat, seed yield, straw yield, and minimum total weed population and dry weight of weed in subsequent wheat were noted with Pyroxasulfone, with at equality Pyroxasulfone as (PE), followed by HW twice (20 and 40 days after sowing), and 2,4-D sodium salt with a combination of 1 HW (60 DAS). The minimum weed population and dry weight of weeds, maximum weed control efficiency and Greengram growth characteristics, number of pods per plant, number of seeds per pod, test weight, seed and straw yields were noted with Pendimethalinat 2 DAS (PE) and Imazethapyr at 30 DAS (PE), which was at par with Imazethapyr as (PE), followed by(fb) Pendimethalin as (PoE), and HW twice at 20 and 40 days after sowing. It can be used for extremelyactive weed control to increase the output of Greengram.
