Effect of Krishi Vigyan Kendra (KVK) intervention for controlling mixed weed flora in wheat at farmers’ fields

The field experiment was conducted at farmers’ fields in Jalandhar and Kapurthala districts of Punjab to see the effect of KVK intervention in controlling mixed weed flora in wheat during 2011–12. Five different herbicide treatments were evaluated in randomized block design. Application of all the herbicides caused a significant reduction in the weed density and weed dry matter over untreated plot. The effective tillers, grains/ear and grain yield were affected significantly by different herbicides application. Spray of metribuzin 125 g/ha+2, 4-D sodium salt @ 625 g/ha provided efficient control of grassy weeds as well as broad leaf weeds in wheat crop and increased grain yield of wheat significantly and gave highest benefit: cost ratio.
