Effect of integrated weed management on growth parameters and yield performance of spinach beet (Beta vulgaris var. bengalensis L.)

The present study was carried out during 2021-2022 at Krishi Vigyan Kendra, Samba, of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu. The experiment comprised of 12 treatments,viz. Oxyfluorfen @ 150 g/ha (Pre-emergence), Oxyfluorfen @ 150 g/ha (Pre-emergence) + 1 handweeding (40 DAS), Pendimethalin @ 750 g/ha (Pre-emergence), Pendimethalin @ 750 g/ha (Pre-emergence) + 1 hand weeding (40 DAS),Imazethpyr @ 70 g/ha (Pre-emergence), Imazethpyr @ 70 g/ha + 1 handweeding (40DAS), Oxadiargyl @ 100 g/ha (Pre-emergence),Oxadiargyl @ 100 g/ha) + 1 handweeding (40DAS), Two hand weeding at 20and 40 DAS, Mulching with paddy straw, Weedy check, andWeed Free. The experiment was laid out ina randomized block design with three replications. The variety used for this experiment was “Jammu Spinach beet-07”. The results revealed that weed weed-free treatment recorded the highest plant height, leaf length, leaf width, leaf area index, and yield(232.77 q/ha), and the weedy check recordedthe minimum yield (113.66 q/ha). Whereas among herbicidal treatments, the Pendimethalin @ 750 g/ha (Pre-emergence) with one hand weeding (40 DAS) outperformed the other treatments.
