Title : Effect of post emergence herbicidal combinations tank mixed with zinc or/and iron sulphate on yield attributes and grain yield of wheat crop (Triticum aestivum L.)

Abstract :

Wheat (Triticum aestivum) is an important cereal crop of the world. Major biotic stress on wheat yield is the weeds. Wheat growing areas are now suffering from deficiency of micronutrients. Field experiment was conducted at RRS, Bawal during Rabi season of 2018-19 to evaluate the post-emergence herbicidal combinations with Zn or/and Fe in wheat. Experiment consisted of 18 treatments replicated thrice, was laid out in Randomized Block Design. Four herbicidal combinations viz. clodinafop + metsulfuron @ 60 g/ha, sulfosulfuron + metsulfuron @ 32 g/ha, mesosulfuron + iodosulfuron @ 14.4 g/ha, pinoxaden + carfentrazone @ (50 + 20g/ha) were evaluated with Zn, Fe and with both Zn as well as Fe. Yield components as well as grain yield of wheat increased significantly under the influence of herbicidal treatments over weedy check. Addition of iron and zinc to the herbicidal combinations resulted into increase in yield components and grain yield of wheat. Application of combined (Zn + Fe) with herbicidal combinations enhanced the grain yield of wheat significantly over application of sole herbicidal combinations. Highest grain yield was obtained under the influence of mesosulfuron + iodosulfuron @ 14.4 g/ha + ZnSO4 (0.5 %) + urea (2.5 %) + FeSO4 (0.5 %).
